How to Get Rid of Smelly Gums: 11 Proven Fixes

If you want to know how to get rid of smelly gums, start by looking for the source of the odor instead of trying to cover it with mint.

Gums themselves do not usually “smell.” What people notice is often bad breath or a bad taste caused by bacteria, plaque, trapped food, tartar, tongue coating, dry mouth, gum disease, decay, or infection.

This distinction matters because the right fix depends on the cause.

A mouthwash may hide odor for a short time. It will not remove hardened tartar, close deep gum pockets, cure a dental abscess, or replace proper cleaning.

This article is for general information and education. It does not replace medical advice, diagnosis, or treatment.

How to Get Rid of Smelly Gums: Quick Answer

The best answer to how to get rid of smelly gums is to remove the source of odor.

Start with these basic steps:

1. Brush your teeth twice a day with fluoride toothpaste.
2. Clean between your teeth once a day.
3. Clean your tongue gently.
4. Drink water regularly.
5. Clean dentures, retainers, bridges, or mouth guards properly.
6. Avoid tobacco.
7. Use mouthwash only as an extra step, not as a replacement for brushing and interdental cleaning.
8. See a dentist if bad breath keeps returning.

If your gums also bleed, swell, recede, feel tender, produce pus, or your teeth feel loose, gum disease becomes more likely.

For a complete daily routine, see our Oral Hygiene Guide.

Do Gums Actually Smell?

Usually, no.

The odor often comes from bacteria and their byproducts.

Bacteria can collect:

• On teeth
• Along the gumline
• Inside gum pockets
• Between teeth
• On the tongue
• Around dental appliances
• Inside cavities

These bacteria break down food debris, dead cells, proteins, and other material.

This process can produce volatile sulfur compounds, which are major contributors to oral malodor.

What Causes Smelly Gums and Bad Breath?

Gingivitis

Gingivitis is early gum inflammation.

Plaque collects along the gumline and may cause:

• Red gums
• Swollen gums
• Tender gums
• Bleeding during brushing or flossing
• Bad breath

Gingivitis can often improve when plaque is removed effectively and professional cleaning is provided when needed.

Periodontitis

Periodontitis is a more advanced form of gum disease.

The gums can pull away from the teeth, creating deeper spaces called periodontal pockets.

These pockets can collect:

• Bacteria
• Plaque
• Tartar
• Food debris

This can produce persistent odor and a bad taste.

Advanced gum disease can also cause:

• Loose teeth
• Pain while chewing
• Gum recession
• Pus
• Bone loss around the teeth

Trapped Food Between Teeth

Food trapped between teeth can begin to break down and create an unpleasant smell.

This is especially common when you have:

• Wide spaces between teeth
• Gum recession
• Crowded teeth
• Bridges
• Braces
• Implants

A toothbrush cannot clean every space between teeth.

This is why daily interdental cleaning matters.

Tartar

Plaque is soft enough to remove at home when you clean well.

If it stays on the teeth, minerals in saliva can harden it into tartar.

Tartar is also called calculus.

You cannot safely brush hardened tartar away.

It needs professional removal.

Tongue Coating

Your tongue can hold:

• Bacteria
• Food particles
• Dead cells

The back of the tongue is a common source of oral odor.

Cleaning the tongue gently may help reduce this buildup.

Dry Mouth

Saliva helps wash away particles and control bacteria.

When saliva production falls, bad breath becomes more likely.

Dry mouth can happen because of:

• Medicines
• Mouth breathing
• Dehydration
• Tobacco
• Alcohol
• Some medical conditions
• Radiation treatment
• Salivary gland problems

Dry mouth is not simply an inconvenience.

It can also raise the risk of tooth decay and oral infection.

Dental Decay

A deep cavity can trap bacteria and food.

Decay can sometimes cause:

• Bad breath
• A bad taste
• Tooth pain
• Sensitivity
• Visible holes or dark areas

Dental Abscess

A dental abscess is a collection of pus caused by infection.

Symptoms may include:

• Severe tooth or gum pain
• Bad taste
• Swelling
• Fever
• Difficulty chewing
• Difficulty opening the mouth

An abscess needs urgent dental treatment.

It does not reliably go away with mouthwash, salt water, antibiotics alone, or painkillers.

Smoking and Tobacco

Tobacco can cause unpleasant breath directly.

It also increases gum disease risk and can make the mouth drier.

Dentures and Dental Appliances

Dentures, retainers, bridges, and mouth guards can hold food and bacteria if they are not cleaned well.

They may also contribute to odor when they do not fit properly.

11 Proven Ways to Get Rid of Smelly Gums

1. Brush Twice Every Day

Brush in the morning and before bed.

Use fluoride toothpaste and clean every tooth surface.

Pay special attention to the gumline.

Do not scrub hard.

Hard brushing can irritate the gums and contribute to recession.

2. Clean Between Your Teeth Every Day

This is one of the most important steps.

You can use:

• Dental floss
• Interdental brushes
• A water flosser
• Another suitable interdental tool

The right tool depends on the size of the spaces between your teeth.

Interdental brushes can be especially useful when gum recession or periodontal disease has created larger spaces.

3. Clean Your Tongue Gently

Use a soft toothbrush or tongue cleaner.

Work gently from the back toward the front.

Do not scrape hard enough to make the tongue sore or bleed.

Tongue cleaning is useful, but it does not replace brushing and interdental cleaning.

4. Have Tartar Removed Professionally

If you can see or feel hard deposits on your teeth, brushing will not remove them.

A dentist or dental hygienist uses professional instruments to remove tartar.

Do not use sharp home tools to scrape your teeth.

You can damage:

• Enamel
• Gums
• Dental work

5. Treat Gingivitis Early

Early gum disease is easier to manage than advanced periodontal disease.

A useful plan may include:

• Better brushing
• Daily interdental cleaning
• Professional cleaning
• Review of plaque traps
• Regular dental follow up

Bleeding gums are a reason to improve gentle cleaning, not a reason to stop cleaning completely.

6. Get Periodontitis Treated Properly

Advanced gum disease needs professional care.

A dentist may measure the depth of the spaces around the teeth with a periodontal probe.

Treatment may include a deeper professional cleaning below the gumline.

Some people need care from a periodontist.

Mouthwash alone cannot remove deep tartar or repair bone loss caused by periodontitis.

7. Keep Your Mouth Moist

If your mouth often feels dry, try:

• Sipping water
• Using sugar free gum if appropriate
• Using sugar free sweets if appropriate
• Reducing tobacco
• Limiting excessive alcohol
• Reviewing medicines with your doctor or pharmacist

Some people benefit from saliva substitutes or other dry mouth treatments.

Do not stop a prescribed medicine because it makes your mouth dry without discussing it with the prescriber.

8. Clean Dentures, Retainers, and Mouth Guards

Clean removable appliances every day according to professional instructions.

Food and bacteria can build up on them just as they do on natural teeth.

Remove dentures at night if your dental team has advised this.

Also clean the gums and tongue.

9. Use Mouthwash for the Right Reason

Mouthwash can help some people.

There are two broad types:

• Cosmetic rinses that mainly mask odor
• Therapeutic rinses that contain active ingredients

Some therapeutic rinses can help reduce plaque, gingivitis, or bad breath.

They are an extra step.

They do not replace brushing or cleaning between teeth.

10. Stop Tobacco

Smoking and smokeless tobacco can:

• Cause bad breath
• Dry the mouth
• Increase gum disease risk
• Delay healing
• Increase oral cancer risk

If you use tobacco, ask a doctor, dentist, or pharmacist about support for quitting.

11. See a Dentist When the Odor Persists

Persistent bad breath deserves investigation.

See a dentist especially if you also have:

• Bleeding gums
• Swollen gums
• Gum recession
• Loose teeth
• Pus
• Tooth pain
• A bad taste
• Visible tartar
• A mouth sore that does not heal

The goal is to find the source rather than repeatedly cover the smell.

How Can You Tell if the Smell Is From Gum Disease?

Bad breath alone cannot diagnose gum disease.

Look for a pattern.

What Does Periodontal Bad Breath Smell Like?

There is no reliable smell test that can tell you whether you have periodontitis.

People sometimes describe gum disease breath as:

• Foul
• Sour
• Metallic
• Sulfur like

Those descriptions are not diagnostic.

A dentist needs to examine the gums, measure pockets when appropriate, and check for tartar, bleeding, recession, and bone loss.

Why Do My Gums Smell When I Floss?

This is a useful clue.

If floss smells unpleasant after passing between certain teeth, it may mean that area is holding:

• Food
• Plaque
• Bacteria

If the same area also bleeds, feels tender, or traps food repeatedly, ask your dentist to examine it.

Possible causes include:

• Gingivitis
• A periodontal pocket
• A cavity
• A poorly fitting filling or crown
• An open contact between teeth

Why Does Food Keep Getting Stuck in My Gums?

Repeated food trapping is worth investigating.

It can happen because of:

• Gum recession
• Spaces between teeth
• Loose dental contacts
• Tooth movement
• Broken fillings
• Poorly shaped dental work

Removing the trapped food is important, but fixing the reason it keeps happening can provide a longer term solution.

Does Flossing Make Bad Breath Worse at First?

Sometimes the odor becomes more noticeable because floss removes trapped debris that was already present.

This does not mean flossing created the problem.

Consistent interdental cleaning should reduce plaque and trapped food over time.

If strong odor keeps returning from one area despite good cleaning, see a dentist.

Should Bleeding Gums Stop You From Flossing?

Usually not.

Mild bleeding commonly occurs when gums are inflamed.

Continue gentle cleaning and improve your technique.

See a dentist if bleeding:

• Keeps happening
• Is heavy
• Comes with swelling
• Comes with recession
• Comes with loose teeth

Should You Use an Interdental Brush?

Interdental brushes can be very useful when the spaces between teeth are large enough.

They may be especially helpful with:

• Gum recession
• Periodontitis
• Bridges
• Implants
• Braces

The brush should fit without being forced.

A dentist or hygienist can help choose the right size.

Do Water Flossers Help?

A water flosser can be useful for some people, especially when traditional floss is difficult to use.

It can help remove debris and improve cleaning around:

• Braces
• Bridges
• Implants
• Hard to reach areas

It should be used as part of a complete oral hygiene routine.

Should You Brush Your Gums?

Brush along the gumline gently.

Do not scrub the gums aggressively.

Hard brushing can damage soft tissue and contribute to recession.

Use a soft bristled toothbrush and gentle pressure.

Does Tongue Scraping Cure Bad Breath?

It can help when tongue coating contributes to the odor.

It does not cure:

• Periodontitis
• Dental abscesses
• Cavities
• Dry mouth
• Faulty dental work

Think of tongue cleaning as one part of oral hygiene rather than a complete treatment.

Which Mouthwash Is Best for Smelly Gums?

The answer depends on the cause.

Cosmetic rinses mainly make the mouth smell fresher for a short period.

Therapeutic products may contain ingredients that help control plaque, gingivitis, or odor.

Examples can include:

• Cetylpyridinium chloride
• Essential oil combinations
• Chlorhexidine in selected situations
• Zinc compounds

Use prescription mouthwash only as directed.

What About Chlorhexidine?

Chlorhexidine can reduce plaque and bacteria and may be useful for selected gum problems.

It is not usually a product to use indefinitely without professional advice.

Possible effects include:

• Tooth staining
• Tongue staining
• Changes in taste

Your dentist may recommend it for a specific period and reason.

Can Mouthwash Replace Floss?

No.

Mouthwash cannot physically remove all the plaque and food between tightly contacting teeth.

Daily cleaning between the teeth remains important.

Can Salt Water Get Rid of Smelly Gums?

Warm salt water may soothe irritated tissues for some people.

It does not remove tartar or cure periodontitis.

It also does not replace dental treatment for an abscess.

Use it as short term comfort care, not as a cure.

Does Hydrogen Peroxide Cure Bad Breath?

Do not create strong homemade peroxide rinses.

Incorrect concentration can irritate or burn oral tissues.

Some commercially formulated oral products contain controlled amounts of peroxide, but that is different from using household peroxide directly.

Does Baking Soda Help?

Some tested toothpastes contain baking soda and can help clean plaque or neutralize acids.

That does not mean rough homemade baking soda scrubs should be used on your gums.

Use a properly formulated toothpaste instead.

Does Apple Cider Vinegar Help Bad Breath?

It is not a good treatment.

Vinegar is acidic.

Repeated exposure can contribute to enamel erosion and oral irritation.

It does not treat the underlying causes of gum disease.

Does Oil Pulling Cure Gum Disease?

No.

Oil pulling is not a replacement for:

• Fluoride toothpaste
• Brushing
• Interdental cleaning
• Professional cleaning
• Periodontal treatment

If you enjoy it and it does not cause problems, it should still be considered an optional extra rather than a gum disease treatment.

Can Probiotics Cure Smelly Gums?

Oral probiotics are being studied, but they are not a replacement for removing plaque and treating gum disease.

Do not use probiotics to delay dental care when you have bleeding, swelling, pus, loose teeth, or persistent bad breath.

How Dry Mouth Causes Bad Breath

Saliva naturally helps clean the mouth.

When the mouth is dry:

• Food debris stays longer
• Bacteria become harder to control
• Odor becomes more noticeable
• Cavity risk rises
• Oral infection risk can rise

Dry mouth can also be caused by hundreds of medicines.

Common examples include some medicines used for:

• Depression
• High blood pressure
• Bladder problems
• Allergies

Do not stop medication on your own.

Ask your doctor, dentist, or pharmacist whether dry mouth management or a medicine review is appropriate.

What Can Help Dry Mouth?

Depending on the cause, useful steps may include:

• Drinking water regularly
• Using sugar free gum
• Using sugar free sweets
• Avoiding tobacco
• Reducing excessive alcohol
• Limiting products that make dryness worse
• Using saliva substitutes when advised

Alcohol containing mouthwash may worsen dryness in some people.

Can Diabetes Cause Smelly Gums?

Diabetes can increase the risk of periodontal disease.

People with diabetes may also experience dry mouth and oral infections more often.

Periodontal disease can cause:

• Persistent bad breath
• Bleeding gums
• Pain
• Chewing problems
• Tooth loss

If you have diabetes and gum problems, good dental care and blood glucose management both matter.

Read our How to Keep Diabetes Under Control Guide for broader diabetes care information.

Can Tonsil Stones Cause Bad Breath?

Yes.

Tonsil stones can trap debris and bacteria.

They can cause a strong smell even when the teeth and gums are reasonably clean.

If a dentist finds no clear oral cause for persistent bad breath, other sources in the nose, throat, or digestive system may need consideration.

Can Acid Reflux Cause Bad Breath?

Reflux can sometimes contribute to bad breath.

However, most persistent bad breath begins in the mouth.

Start with a dental assessment before assuming the stomach is the cause.

Can Stomach Problems Cause Smelly Gums?

Usually the smell is not coming from the stomach.

Oral causes are much more common.

A dentist can check for:

• Gum disease
• Decay
• Dry mouth
• Tongue coating
• Dental infections

If those are ruled out, another healthcare professional may look for other causes.

Can Food Cause Smelly Gums?

Food can affect breath in two ways.

Food Trapped in the Mouth

Food left between teeth can break down and feed bacteria.

Food Absorbed Into the Body

Garlic, onions, spices, and some other foods can affect breath after digestion because their compounds enter the bloodstream and are later exhaled.

Brushing cannot immediately remove this second type.

Can Bad Breath Come From Dental Crowns or Bridges?

Yes, especially if plaque or food collects around them.

Problems may include:

• Poor cleaning access
• A loose crown
• Decay underneath
• A poorly fitting margin
• Food trapping beneath a bridge

Your dentist or hygienist can show you the best cleaning tool for the area.

What About Dental Implants?

Implants need daily cleaning too.

Inflammation around an implant can lead to:

• Bleeding
• Swelling
• Bad taste
• Odor
• Bone loss in more advanced disease

Persistent symptoms around an implant should be assessed.

How Long Should Bad Breath Take to Improve?

If the problem is mainly trapped food or tongue coating, you may notice improvement quickly after better cleaning.

Gingivitis may take longer because the gums need time to become less inflamed.

Periodontitis may not improve adequately until professional treatment removes deposits below the gumline.

There is no single timeline for every cause.

When Should You See a Dentist?

Arrange a dental appointment if you have:

• Bad breath that keeps returning
• Bleeding gums
• Swollen gums
• Painful gums
• Gum recession
• A persistent bad taste
• Visible tartar
• Pus
• Loose permanent teeth
• Persistent tooth sensitivity
• Food constantly trapping in one area

NHS guidance specifically advises seeing a dentist for bad breath and symptoms of gum disease.

When Is Dental Care Urgent?

Ask for urgent dental care if you have:

• Severe gum or tooth pain
• A dental abscess
• Facial or jaw swelling
• Fever with dental pain or swelling
• Pus
• Difficulty opening your mouth

When Is It an Emergency?

Seek emergency medical care if swelling makes it difficult to:

• Breathe
• Speak
• Swallow

Also seek emergency help for severe mouth or neck swelling or swelling affecting the eye or vision.

Common Smelly Gum Myths

Myth 1: Mouthwash Cures Gum Disease

False.

Mouthwash may help control some bacteria or odor, but it cannot remove hardened tartar or treat deep periodontal pockets by itself.

Myth 2: Bleeding Means You Should Stop Flossing

False.

Bleeding often signals gum inflammation.

Clean gently and seek dental advice if it keeps happening.

Myth 3: Bad Breath Comes From the Stomach

Usually false.

Most bad breath begins in the mouth.

Myth 4: Mint Gum Fixes the Cause

False.

Mint may mask odor temporarily.

Sugar free gum may help saliva flow, but it does not treat tartar, cavities, or periodontitis.

Myth 5: Tartar Can Be Scraped Off at Home

False.

DIY scraping can injure gums and teeth.

Myth 6: Natural Remedies Are Always Safer

False.

Vinegar, strong peroxide, harsh powders, and essential oils can irritate or damage oral tissues.

A Daily Routine for Healthier Gums and Fresher Breath

Morning

1. Brush for about two minutes.
2. Use fluoride toothpaste.
3. Brush gently along the gumline.
4. Clean the tongue if needed.

During the Day

1. Drink water regularly.
2. Limit tobacco.
3. Use sugar free gum when appropriate.
4. Rinse removable appliances after meals when practical.

Before Bed

1. Clean between the teeth.
2. Brush for about two minutes.
3. Clean removable dental devices.
4. Follow any mouthwash instructions from your dentist.

Conclusion

Learning how to get rid of smelly gums starts with finding the real source of the odor.

Plaque, trapped food, tongue bacteria, dry mouth, gingivitis, periodontitis, dental decay, appliances, and infection can all contribute.

The most useful routine is simple: brush twice a day with fluoride toothpaste, clean between the teeth daily, clean your tongue gently, stay hydrated, and keep dental appliances clean.

If the smell keeps returning, do not keep adding stronger mouthwash.

A dentist can check for tartar, gum pockets, decay, dry mouth, abscesses, and other causes that home care cannot fix.

Your next step is simple: clean thoroughly tonight, then look at your gums. If you see repeated bleeding, swelling, recession, pus, or loose teeth, arrange a dental examination.

Frequently Asked Questions

How do you get rid of smelly gums?

Brush twice a day with fluoride toothpaste, clean between the teeth daily, clean the tongue gently, drink enough water, clean dental appliances, and avoid tobacco. Persistent odor needs a dental check because gum disease, tartar, cavities, dry mouth, or infection may be present.

Why do my gums smell when I floss?

Food, plaque, or bacteria may be trapped between the teeth. If the smell comes from the same place repeatedly or the area bleeds, hurts, or traps food often, ask a dentist to examine it.

Can gum disease cause bad breath?

Yes. Gingivitis and periodontitis can cause persistent bad breath. Periodontitis can create deep pockets around teeth that collect plaque, tartar, and bacteria.

Can mouthwash cure smelly gums?

No. Some therapeutic mouthwashes can reduce bacteria and odor, but they do not replace brushing, interdental cleaning, tartar removal, or periodontal treatment.

Should I floss if my gums bleed?

Usually yes, but clean gently. Gum inflammation is a common reason for bleeding. See a dentist if bleeding continues, becomes heavy, or comes with swelling, recession, pus, or loose teeth.

Does tongue scraping help bad breath?

It can help reduce bacteria and coating on the tongue, which may improve breath. It does not cure gum disease, cavities, abscesses, or dry mouth.

Can dry mouth cause bad breath?

Yes. Saliva helps clean the mouth and control bacteria. Low saliva flow can increase bad breath, tooth decay, and oral infection risk.

Does salt water cure gum disease?

No. Salt water may soothe irritated gums for a short time, but it cannot remove tartar or treat advanced periodontitis.

Can a dental abscess cause a bad smell?

Yes. A dental abscess may cause pus, a bad taste, bad breath, severe pain, swelling, or fever. It needs urgent dental treatment.

Can diabetes cause gum odor?

Diabetes can increase the risk of periodontal disease and dry mouth. Both can contribute to persistent bad breath.

When should I see a dentist for bad breath?

See a dentist when bad breath persists despite good oral hygiene or comes with bleeding gums, swelling, recession, pus, loose teeth, tooth pain, visible tartar, or a persistent bad taste.

When is gum swelling an emergency?

Seek emergency care if swelling makes it difficult to breathe, speak, or swallow, or if severe swelling affects the mouth, neck, eye, or vision.
