How often do I need a cleaning?

Clinical review: Not reviewed by a dentist and not medical advice

The short answer

Many adults visit twice a year, but the right gap is individual. For check-ups and cleanings, it can be as short as three months for someone with gum disease or a high risk of cavities, and longer for someone whose mouth has stayed healthy. Your dentist or hygienist can set a schedule for you after an exam.

The American Dental Association recommends seeing your dentist regularly, without fixing one number for everyone.

Where "every six months" comes from

Six months is a habit, not a law of nature. It is a convenient, memorable gap, and many dental plans are built around two visits a year. The research covers two different questions: how often to have a check-up (an examination), and how often to have a professional cleaning.

• Check-ups for adults. A 2020 Cochrane review found high-certainty evidence of little or no difference, over about four years, in tooth decay, gum disease and quality of life between risk-based check-up intervals and check-ups every six months. Moderate- to high-certainty evidence found similar results with 24-month intervals.
• Check-ups for children and teenagers. The same review judged the evidence uncertain, so it cannot say which interval suits children.
• Cleanings for healthy adults. A separate Cochrane review found that a routine scale and polish every six months reduced hardened plaque (calculus) a little more than one every twelve months. The clinical importance of that small difference is uncertain.
• Guidance. The UK's NICE guideline tells dentists to set each person's interval between oral health reviews by their risk of oral disease, from 3 to 24 months for adults. It concerns check-ups. It is not a standard cleaning schedule.

So your dentist sets your examination and cleaning schedule according to your needs, rather than by one rule.

What affects your interval

Shorter gaps, such as every three or four months, are often suggested if you have:

• Gum disease, or a history of it.
• Frequent cavities, or new cavities at recent visits.
• Dry mouth, which can be caused by some medicines or health conditions.
• Diabetes, which is linked with gum problems.
• Smoking or tobacco use.
• Braces, aligners or other work that traps plaque.
• Heavy build-up of tartar between visits.

A longer gap can suit adults whose gums are healthy, who rarely get cavities, who brush and clean between teeth well, and who have shown over several visits that their mouth stays healthy. The change is usually made gradually, with your dentist's agreement.

What a cleaning does

A routine cleaning (dentists call it a prophylaxis) removes plaque and tartar from the teeth above the gum line and polishes the surfaces. A hygienist usually does it. It is normally combined with an examination, so the dentist can check for decay, gum problems and changes in the mouth, and with X-rays when you need them.

A cleaning does not replace brushing twice a day with fluoride toothpaste and cleaning between your teeth once a day.

A deeper cleaning is different

Early gum inflammation may improve with professional cleaning and daily home care. If gum disease has progressed, your dentist may recommend scaling and root planing and ongoing periodontal maintenance. The American Dental Association explains that scaling and root planing cleans below the gum line, then smooths the roots so the gums can reattach. It may take more than one appointment and use local anesthetic. This is why the cost estimator lists deep cleaning as not included in the new-patient exam and cleaning.

Insurance is separate from need

Many plans cover two cleanings a year, which can make "every six months" feel like a rule. Your plan's benefits and your clinical need are separate questions. If your dentist suggests a different interval, ask what your plan covers and what you would pay, before booking.

Children

For children and teenagers, NICE suggests review intervals of 3, 6, 9 or 12 months, depending on risk, though the Cochrane review found the evidence uncertain. The American Dental Association says to schedule a child's first dental visit after the first tooth comes in and no later than the first birthday.
