How to Get Rid of Bad Breath from Mouth?

Covering your mouth while speaking mid-sentence is embarrassing. If you’ve been wondering how to prevent bad breath, you are not alone. According to the American Dental Association (ADA), approximately 50 percent of adults suffer from bad breath at some time in their lives. The NHS says it’s also “very common” and you can typically treat it at home.

The best news? Most forms of bad breath originate in the mouth, and most cases will respond to simple changes in your habits. Below, we discuss the causes and provide nine steps that can get rid of bad breath. We will also explain when you know it’s time to see a professional. Let’s dig in. 

What Fixes Bad Breath Fastest?

Clean your whole mouth, not just your teeth. The NHS says the best way to avoid bad breath is to keep your teeth, tongue, and mouth clean. Here is the short version:

1. Brush gently twice a day for two minutes with fluoride toothpaste
2. Clean your tongue once a day
3. Clean between your teeth daily
4. Keep your mouth moist and your saliva flowing
5. Skip smoking and cut back on alcohol and sugar
6. See your dentist if the smell lingers beyond a few weeks

Next, let’s look at why your mouth smells in the first place.

What Causes Bad Breath?

The ADA explains that hundreds of types of bacteria live in your mouth naturally, and your mouth is warm and moist enough to let them grow. Odor appears when the balance tips. Here are the usual reasons.

Bacteria on Your Tongue

According to Victoria’s Better Health Channel, the main cause of bad breath is sulfur producing bacteria that thrive on your tongue’s surface and in your throat. Because the tongue has a rough surface that collects food debris and bacteria, this is where you’ll find odor if you have a coated tongue. You can have great teeth yet suffer from bad breath by neglecting this area.

Gum Disease, Cavities, and Infections

The ADA says bad breath that will not go away, or a constant bad taste in your mouth, can warn of advanced gum disease. The NHS lists gum disease, holes in your teeth, and infections among the causes. Cleveland Clinic adds that a tooth abscess, a pocket of pus from infection, can release a foul odor. Smell from these sources will not fade with mints. The cause needs treatment.

Dry Mouth

Saliva washes away food particles and bacteria. If you don’t produce enough saliva odors will accumulate. The ADA notes that dry mouth can result from particular medications, salivary gland issues or just breathing through your mouth. According to Livestrong other diseases like uncontrolled diabetes and Sjogren’s can create dry mouth. Dry mouth should be high on your suspect list if you wake up with sour breath.

Food, Drink, Tobacco, and Crash Dieting

The NHS lists strong-smelling or spicy foods and drinks, smoking, and fasting or crash dieting among the causes of bad breath. It also advises limiting alcohol and sugary foods and drinks. The Better Health Channel says smoking starves the mouth of oxygen. These causes are easy to fix, but you have to notice them first.

Medical Conditions

Sometimes it comes from outside your mouth. NHS lists dry mouth, tonsillitis, and acid reflux. Cleveland Clinic includes tonsil stones. They’re small pieces of hardened calcium that develop when food debris gets trapped in your tonsils. They also note diabetes, which increases your chances of gum disease. They add reflux along with kidney disease and liver disease. Your sense of smell can also help you detect the problem. 

Chronic conditions might cause your breath to smell fishy or like rotten eggs, per Cleveland Clinic. If you smell fruity breath on someone with diabetes, however, that could indicate diabetic ketoacidosis. That’s a potentially life-threatening complication that needs medical attention.

Test Yourself First: Do You Have Bad Breath?

You often cannot smell your own breath. NI Direct, the UK government’s public information service, says it is not always easy to tell. It suggests a simple test: lick the inside of your wrist, let it dry for a moment, and smell it. If your wrist smells unpleasant, your breath likely does too. You can also ask someone you trust for an honest answer. A quick check beats guessing.

How to Get Rid of Bad Breath: 9 Steps That Work

Follow these steps in order. Most come straight from NHS and ADA guidance.

1. Brush gently, twice a day, for two minutes: Use fluoride toothpaste. The NHS says not to brush so hard that your gums or tongue bleed. It also says not to rinse with water straight after brushing, so the toothpaste can keep working. Spit, then stop.
2. Clean your tongue every day: The NHS recommends a tongue scraper or cleaner once a day. The ADA says a toothbrush works too. Since sulfur-producing bacteria collect on the tongue, this step often makes the biggest difference. Use light pressure. If your tongue bleeds, ease off.
3. Clean between your teeth daily: Use floss or interdental brushes at least once a day, says the NHS. Food that stays between teeth feeds bacteria. The ADA notes that the longer you wait to brush and floss food away, the more likely your breath will offend.
4. Keep your mouth moist: The ADA suggests chewy foods to keep saliva flowing. The NHS recommends sugar-free mints or gum after strong-smelling food and drink. Sip water through the day. If a medicine dries your mouth, talk to your doctor or dentist. Do not stop it on your own.
5. Use an antibacterial mouthwash after cleaning: The NHS says to try an antibacterial mouthwash or toothpaste. The ADA says over-the-counter rinses can help kill bacteria or neutralize and temporarily mask odor. Rinse after brushing and flossing, never instead of them.
6. Rethink what and when you eat: Spicy and strong-smelling foods leave odor behind. The NHS says fasting and crash dieting can cause bad breath too, so eat regular meals. Cut back on alcohol and sugary drinks.
7. Quit smoking: The NHS tells people not to smoke. The ADA says smoking stains your teeth, gives you bad breath, and raises many other health risks. Ask your doctor or dentist about support to quit.
8. Clean your dentures: The NHS says to keep dentures clean and take them out at night. The ADA also recommends cleaning them regularly. Plaque and food cling to dentures just as they cling to teeth.
9. Get regular check-ups: The ADA says regular check-ups let your dentist spot problems such as gum disease or dry mouth before they become more serious. A professional cleaning removes buildup that home care misses.

Give these steps a few weeks. The NHS says to see a dentist if bad breath does not go away after you treat it yourself for a few weeks.

What Does Not Work: Masking the Smell

Mints and mouth sprays feel like a fix. They are not. The ADA says over-the-counter mouthwash can temporarily mask bad breath, and it warns that mouthwash alone does not treat the cause. If you reach for a breath freshener all day to cover an odor, the odor has a source that needs attention.

One more tip from NI Direct: when you seek medical advice, do not try to hide the smell beforehand. Your dentist or doctor needs to smell it to find the cause.

When to See a Dentist or Doctor

The NHS says to see a dentist if you have:

• Bad breath that does not go away after a few weeks of self-care
• Painful, bleeding, or swollen gums
• Toothache or wobbly adult teeth
• Problems with your dentures

See a doctor if your dentist finds a healthy mouth. Cleveland Clinic says that when bad breath sticks around despite good oral hygiene, you should start with a dentist. If everything looks fine from a dental standpoint, your family doctor can investigate other causes such as sinus problems, reflux, or tonsil stones. Seek urgent care for fruity-smelling breath if you have diabetes.

What a Dentist Can Do That Home Care Cannot

That dentist will find causes you can’t. For example, NI Direct says your dentist will find signs of gum disease and help you get treated early. Causes such as a hidden cavity, tooth abscess or buildup beneath the gums will continue to cause odor despite brushing well. Rudra Dental Smilelature in Salem lists services that can target each of those issues. One is root canal treatment, which will remove infection in your damaged tooth. Another is gingival flap surgery to deep clean areas affected by severe gum disease. 

It also lists check-ups, as well as laser dentistry that takes care of gum issues with a Pioon soft-tissue laser. Check with any dentist to see which of these options would apply to your case. There are many cases where all that is needed is a professional cleaning and improved daily care. Denture wearers and elderly adults can take note that this clinic lists geriatric dentistry. Services include denture options and preventing gum disease. The NHS specifically links bad breath to dirty dentures, so that is important care to consider.

Next Steps

Begin tonight. Brush gently. Clean tongue. Floss. Don’t rinse with plain water afterwards. Stay hydrated. Avoid smoking, alcohol, sugars, and wait two or three weeks. Most people experience dramatic improvement. 

If the odor remains, visit your dentist. At Rudra Dental Smilelature in Salem, we can check your teeth, gums, dentures. Any dentist can do this. Don’t live with this for months. Many times it can be found in a quick visit.

FAQs

Can bad breath come from the stomach?

Sometimes, but most bad breath starts in the mouth. The NHS lists acid reflux as one medical cause. If your mouth is healthy and the smell persists, a doctor can check for reflux, sinus problems, or other conditions.

Why does my breath smell even after brushing?

You may be missing your tongue, the spaces between your teeth, or a deeper problem such as gum disease, a cavity, or dry mouth. Add tongue cleaning and flossing. If the smell lasts a few weeks, see a dentist.

Does mouthwash cure bad breath?

No. The ADA says over-the-counter mouthwash can kill some bacteria and temporarily mask odor, but it does not treat the underlying cause. Use it after brushing, flossing, and tongue cleaning, and see a dentist if the smell keeps returning.

How can I check my own breath?

Lick the inside of your wrist, wait a moment, and smell it. NI Direct says an unpleasant smell there likely means your breath smells too. You can also ask a trusted friend or family member for an honest opinion.

When is bad breath a sign of something serious?

See a professional if bad breath lasts weeks despite good hygiene or comes with painful gums, loose teeth, or toothache. Seek urgent medical help for fruity-smelling breath if you have diabetes. Fishy or rotten-egg smells can point to chronic conditions.
