- Plaque is a sticky bacterial film on the teeth; it can cause cavities and gum disease.
- If plaque is not removed daily, it can harden into tartar (calculus).
- Tartar above the gum line can lead to swollen, bleeding gums, an early stage of gum disease called gingivitis.
- Prevent both with fluoride toothpaste twice a day, daily cleaning between teeth and regular dentist visits.
What plaque is
Plaque is a sticky film that covers your teeth, according to the ADA. It contains bacteria that can contribute to tooth decay and gum disease. After you eat or drink something with sugar, those bacteria release acids that attack tooth enamel. Repeated attacks can break down enamel and eventually cause cavities.
What tartar is
Tartar, also called calculus, forms when plaque is not removed by thorough daily brushing and cleaning between the teeth. The plaque hardens, and once it has, it becomes harder to keep teeth clean. When tartar builds up above the gum line, the gums can swell and bleed easily. The ADA calls this early stage of gum disease gingivitis.
The difference in one line
Plaque is a soft film that daily cleaning can remove. Tartar is plaque that was left long enough to harden.
How to prevent both
- Brush twice a day with fluoride toothpaste.
- Clean between your teeth daily with floss or another interdental cleaner.
- See your dentist regularly.
Pay special attention to the places a brush reaches poorly, like along the gum line and the back teeth.
What if I already have tartar?
The ADA page we reviewed does not describe how tartar is removed, so we will not guess. Ask your dentist how often you should be seen and what they recommend for the buildup you have. Do not scrape it yourself with sharp tools, because you can hurt your gums and teeth.
Signs it is time to book a visit
- Gums that bleed easily when you brush or floss
- Swollen or tender gums
- Persistent bad breath
- Visible hard buildup near the gum line
Plaque that stays long enough is what leads to gum trouble. Our pages on reversing gingivitis and bleeding gums when flossing show what happens next, and the best cordless water flosser and best toothpaste for gingivitis guides compare everyday tools.
Tools that help keep plaque in check
Daily cleaning between teeth and brushing are what stop plaque hardening into tartar. These are tools people use for that. We have not tested these products; the details below come from the listings and brands, and prices and availability change often.
Oral-B iO Series 3 Rechargeable Electric Toothbrush
A rechargeable electric toothbrush with three modes (including Sensitive), a pressure sensor and a two-minute timer. The listing shows about 4.3 stars from roughly 19,400 ratings. Electric toothbrushes can make a thorough two-minute routine easier, but technique matters more than any gadget.

If you want to step up (higher-priced options)
