Have you ever felt a hard, crusty spot on your teeth — or had a piece of it chip off? That's tartar. Tartar buildup on teeth is common, and once it forms, you can't brush it away. Here's what tartar is, what it means when tartar starts breaking off your teeth, and how to get rid of it safely.
What Is Tartar?
Tartar (also called dental calculus) is hardened dental plaque. Plaque is the soft, sticky film of bacteria that coats your teeth every day. If you don't remove it by brushing and flossing, minerals in your saliva harden it into tartar within a few days.
Tartar is rough, hard, and usually yellow, ivory, or brown. It often builds up along the gumline and behind your lower front teeth. You may feel it as a sharp or gritty spot when you run your tongue over your teeth.
Can Tartar Fall Off My Teeth?
Sometimes, yes. A piece of tartar can break off on its own — especially near the gumline, where deposits get thick. It can also chip off when you eat something hard or crunchy.
But tartar breaking off your teeth is not a good sign. It usually means the buildup has gotten heavy. And the tartar left behind is still rough and full of bacteria. If you notice tartar breaking off, it's time to schedule a dental cleaning — not a reason to wait.
Why Tartar Buildup on Teeth Is a Problem
Tartar does more than look bad. Because it's rough and porous, it gives plaque bacteria even more places to stick. Over time, that can lead to:
- Tooth decay: bacteria in plaque make acids that wear down enamel and cause cavities.
- Gum disease: tartar at the gumline irritates gum tissue. Gums get red, puffy, and bleed easily — the first stage of gum disease, called gingivitis.
- Bad breath: the bacteria trapped in tartar cause an odor that brushing can't fix.
- Stains: tartar soaks up color from coffee, tea, and other foods, so it darkens over time.
Don't Try to Remove Tartar Yourself
It's tempting to pick at tartar or scrape it with something sharp. Don't. You can cut your gum tissue, scratch your enamel, and push bacteria deeper under the gumline. Only a dentist or dental hygienist has the right tools to remove tartar safely. Removing it is a normal part of a professional cleaning — learn more about how dentists remove tartar from teeth.
If buildup has spread below the gumline, your dentist may suggest a deep cleaning. Here's the difference between a regular cleaning and a deep cleaning.
How to Prevent Tartar Buildup
The best way to fight tartar is to stop plaque from hardening in the first place. Removing plaque every day is simple:
- Brush your teeth twice a day with a fluoride toothpaste and a soft-bristled toothbrush. Replace your toothbrush every three months.
- Floss once a day to clean the spots your toothbrush can't reach.
- Rinse with a fluoride mouthwash to wash away leftover bacteria.
- Cut back on sugary snacks and drinks, which feed plaque bacteria.
- Don't smoke. Smoking speeds up tartar buildup.
- Visit your dentist every six months for a checkup and cleaning.
Frequently Asked Questions About Tartar Buildup
Is tartar breaking off my teeth a good thing?
No. It might feel like progress, but it usually means the buildup is heavy. The tartar that remains still holds bacteria against your teeth and gums. Schedule a cleaning so a professional can remove all of it.
What does tartar buildup on teeth look like?
It looks like hard, crusty deposits that range from pale yellow to brown. It usually shows up along the gumline and between teeth, and it feels rough or sharp to your tongue.
Can I remove tartar at home?
No. Once plaque hardens into tartar, brushing and flossing can't remove it — and scraping at it can hurt your gums. A dentist or dental hygienist removes it safely during a routine cleaning.
How fast does tartar form?
Plaque can start hardening into tartar within about 24 to 72 hours. That's why daily brushing and flossing matter so much.
