What is the difference between plaque and tartar?

Status: Approved

Short answer: Plaque is the sticky film of bacteria that's constantly forming on your teeth. You can remove it by brushing and cleaning between your teeth. Tartar, also called calculus, is plaque that has hardened. The ADA says once tartar forms, only your dentist can remove it. Both can lead to gum disease and cavities.

Plaque

The ADA describes plaque as a sticky film containing bacteria. After you eat or drink something sugary, those bacteria release acids that attack enamel. Over time this can cause cavities. Plaque also irritates the gums.

Tartar

Plaque that isn't removed by daily brushing and cleaning between teeth can harden into tartar. The ADA notes that tartar builds up along the gumline. It makes teeth harder to keep clean.

Why it matters

When tartar collects above the gumline, the ADA says gums can become swollen and bleed easily. This is gingivitis, the early stage of gum disease. If gum disease advances, a deeper cleaning may be needed. See Regular cleaning vs. deep cleaning.

Prevention

  • Brush twice a day with fluoride toothpaste.
  • Clean between your teeth every day.
  • Get regular dental checkups and professional cleanings.

Frequently asked questions

Can I remove tartar at home?
No. The ADA says only your dentist can remove tartar once it forms.

How often should I get a cleaning?
We recommend a cleaning every 6 months for healthy adults and children, and every 3 months for gum disease.

Does flossing help prevent tartar?
Yes. The ADA says daily flossing helps prevent the plaque buildup that hardens into tartar.
