Yes, you should brush your tongue every day. Your tongue harbors a large share of the bacteria in your mouth, and cleaning it helps fight bad breath, supports fresher breath, and keeps your whole mouth healthier. Brushing your teeth alone isn’t enough.
- Your tongue harbors bacteria in its textured crevices that brushing your teeth and rinsing alone cannot remove.
- A coated tongue is one of the most common causes of persistent bad breath, even after brushing your teeth.
- Regular tongue brushing is scientifically proven to reduce oral bacteria and may also support heart and brain health by limiting harmful bacteria from spreading beyond the mouth.
- Tongue bacteria can dull your sense of taste and contribute to oral yeast infections, making regular cleaning important beyond just fresh breath.
- Clean your tongue twice daily using a toothbrush or tongue scraper with light, gentle pressure — the same force used on your teeth is enough.
Most people focus on their teeth and stop there. But research shows your mouth is home to more than 700 types of bacteria — and many of them settle into the crevices of your tongue, where brushing your teeth never reaches. Left there, that buildup can contribute to bad breath and other oral health issues. Here’s why tongue cleaning deserves a daily spot in your routine, and how to do it right.
Why Should You Brush Your Tongue?
Your tongue isn’t smooth. Its rough, textured surface has countless tiny crevices where bacteria love to hide, tucked in between your taste buds. If you’re not cleaning your tongue regularly, that bacteria can linger and, over time, contribute to problems ranging from bad breath to gum issues. Bacterial buildup in the mouth has even been linked to broader health concerns.
6 Reasons Why You Should Brush Your Tongue
1. Rinsing Alone Won’t Do the Trick
You can’t simply swish away tongue bacteria. The buildup forms a sticky biofilm on the surface of your tongue, and mouth rinses only reach the top layer. Brushing or scraping is the only way to break up all the layers and physically remove the bacteria.
2. Your Tongue May Be the Reason Your Breath Smells
Ever wonder why your breath still isn’t fresh after brushing your teeth? A coated tongue is often the culprit. Bacteria collect there if you smoke, have dry mouth, practice poor oral hygiene, or take certain medications. Cleaning your tongue breaks up the bacteria your toothbrush leaves behind.
3. Tongue Brushing Actually Works
The science backs it up. Studies have found that regularly brushing the tongue significantly reduces the amount of bacteria in the mouth, with results improving the longer the habit is kept up. Simply put: the more consistently you brush your tongue, the cleaner your mouth becomes.
4. Tongue Bacteria Can Affect Your Heart and Brain
Oral bacteria don’t always stay in your mouth. Research suggests bacteria from the mouth may contribute to inflammation in the body, which has been linked to heart problems and conditions affecting the brain. Keeping your mouth clean — tongue included — is one simple way to support your overall health. Persistent gum problems are worth addressing too; if your gums bleed or feel sore, gum disease treatment can help.
5. Tongue Bacteria Affect Your Sense of Taste
When biofilm builds up over your taste buds, it can dull your sense of taste. Food may not taste as vivid as it should. Brushing your tongue clears that coating away and helps keep your taste buds working their best.
6. You Could Develop a Yeast Infection in Your Mouth
Oral yeast infections can develop where bacteria accumulate. White patches on the tongue can be one sign. Cleaning your tongue regularly helps reduce the buildup that contributes to these infections.
How to Clean Your Tongue Properly
The next time you ask yourself, “Should I brush my tongue?” — the answer is yes. Here’s how to do it the right way:
- Choose your tool. Use your toothbrush or a dedicated tongue scraper. Some toothbrushes even have a scraper built into the back.
- Brush your teeth first. Clean your teeth as usual, then rinse and wash off your toothbrush.
- Scrub your tongue. Apply a little toothpaste and gently brush back and forth, then side to side. Stick your tongue out to reach as far back as you comfortably can.
- Cover the whole surface — gently. Don’t scrub hard enough to make your tongue bleed. The same pressure you use on your teeth is plenty; scrubbing harder won’t remove more bacteria.
- Rinse and repeat daily. Rinse when you’re done, and clean your tongue twice a day. An antibacterial rinse afterward is a nice finishing touch.
Finally, rinse your toothbrush, let it dry, and replace it regularly — bacteria can build up on the brush itself. Pairing this daily habit with a professional dental cleaning and a routine dental exam keeps your whole mouth fresh and healthy.
Frequently Asked Questions
Should I brush my tongue every day?
Yes. Cleaning your tongue twice a day, whenever you brush your teeth, helps remove the bacteria that cause bad breath and contribute to other oral health issues. It’s a simple but important part of a daily routine.
Is a tongue scraper better than a toothbrush?
Both work well. A tongue scraper is designed specifically to lift bacteria from the tongue’s surface, but a toothbrush does a good job too. Use whichever you’ll stick with consistently.
Why does my breath still smell after brushing my teeth?
A coated tongue is a common reason. Bacteria build up in the crevices of the tongue and aren’t removed by brushing teeth or rinsing alone. Cleaning your tongue often resolves lingering bad breath.
Can brushing my tongue too hard cause damage?
Yes. Scrubbing too aggressively can irritate or even injure your tongue. Use gentle, even pressure — about the same as brushing your teeth — and stop if your tongue feels sore or bleeds.
