Most people should get their teeth professionally cleaned about every 6 months, but some need cleanings as often as every 3–4 months depending on gum disease risk, history of cavities, and other factors. At an absolute minimum, adults should have a dental checkup with cleaning at least once a year to catch problems early.

General guideline

  • For healthy adults with low risk of cavities or gum disease, twice-yearly cleanings (every 6 months) are the standard recommendation.
  • These visits remove tartar that brushing and flossing cannot, and allow early detection of issues like cavities or gingivitis.

When you may need more often

You may benefit from cleanings every 3–4 months if you:

  • Have or previously had periodontitis (gum disease) or are at high risk for it.
  • Frequently get cavities, smoke, have diabetes, or struggle to keep plaque under control at home.

When you might stretch to once a year

Some research has suggested that the “every 6 months” rule is somewhat arbitrary and that ideal frequency depends on individual risk. For low-risk patients with excellent home care and no history of gum disease, a dentist may sometimes space cleanings closer to once a year, but an annual exam is still strongly recommended.

How to decide your schedule

  • Ask your dentist for a personalized cleaning interval based on your gum health, cavity history, medical conditions, and lifestyle.
  • If you notice bleeding gums, bad breath, or tartar buildup before your next scheduled visit, that is a sign your current interval may be too long and you may need more frequent care.
