    How often should I go for a checkup?

    Your dentist sets the gap between checkups, based on your own teeth and risks. Enter what they told you to see your next date and get a reminder.

    What your dentist weighs up

    From the UK's NICE guideline on checkup intervals (CG19), in plain words.

      Is every 6 months a must?

      A routine cleaning and checkup usually takes 30 to 60 minutes in the chair. Bigger jobs, like a crown or a root canal, take about 1 to 2 hours a visit and often need two visits. Your dental office knows exactly how long they've booked.

      How long does a dental cleaning and checkup take?

      About 30 to 60 minutes. Cleveland Clinic says most cleanings take 30 to 60 minutes, and special cleanings take longer. A cleaning means scaling (scraping off plaque and tartar) and polishing. X-rays or fluoride may be added.

      A checkup exam on its own is shorter. An NHS dental center in Scotland says routine exam appointments usually last 20 to 30 minutes. In a 2023 survey, dentists in Wales estimated about 11 minutes for the exam itself, on average.

      At a checkup, your dentist examines your teeth, gums and mouth, asks about your health and habits, and talks about when to come back (NHS, NICE).

      How long does a deep cleaning take?

      About 1 to 2 hours for the whole mouth, done in one visit or half the mouth at a time over two visits (Cleveland Clinic). University Hospitals of Leicester says it can take up to 2 hours, often over 2 visits. Your gums are usually numbed first.

      A deep cleaning (scaling and root planing) cleans below the gum line. We found no trusted figure per quadrant (a quarter of your mouth), so for one or two quadrants the tool uses half the whole-mouth time: 30 to 60 minutes.

      How long does a new-patient exam take?

      Up to about 90 minutes at a dental school clinic. Harvard Dental Center says a first full evaluation can take up to 90 minutes, and the University of Louisville books a 90-minute evaluation. Louisville says visits there run longer than at a private practice, because teachers check each step. At Boston University's student clinic, every appointment lasts about 3 hours.

      We found no trusted figure for a first visit at a private office, so ask when you book. At Boston University, the first visit includes X-rays, and the cleaning comes at the next visit. Harvard and Boston University ask you to arrive 15 minutes early for forms; the tool adds this to your time at the office.

      How long do fillings, crowns and root canals take?

      TreatmentTime in the chairVisits
      Filling20 min – 1 hr each1
      Crown made in a lab1–2 hr, then up to 1 hr to fit it2, about 2–3 weeks apart
      Same-day crownNo trusted figure1
      Root canal1 hr – 1 hr 30 min a visit1–2
      Tooth extraction (one tooth)30 min – 1 hr1
      Wisdom tooth removalA few minutes up to about 1 hr1
      Implant placement (one implant)About 30 min1 for the surgery
      In-office whitening30 min – 1 hr1

      Fillings. A filling usually takes an hour or less, and a simple one may take as few as 20 minutes (Healthline, reviewed by a dentist). Large fillings take longer. White (composite) fillings take longer to place than silver (amalgam) ones, because there are more steps (Bristol Dental School). A regular filling is done in one visit (Cleveland Clinic).

      Crowns. A crown made in a lab usually takes two visits (Cleveland Clinic). At the first, your dentist shapes the tooth, takes impressions or a digital scan, and fits a temporary crown. The lab takes about 2 to 3 weeks. One NHS hospital leaflet says the first visit can take 1 to 2 hours and the fitting up to 1 hour. A same-day crown made on site takes one visit, but we found no trusted figure for its length.

      Root canals. Cleveland Clinic says most root canals take about 60 to 90 minutes. The American Association of Endodontists (AAE) says most need one or two appointments of roughly 90 minutes. The NHS says appointments may last 1 to 2 hours, and treatment usually takes two or more. So sources disagree a little.

      Molars (back teeth) take longest, because they have several root canals. In two studies, total treatment averaged about 37 to 48 minutes for teeth with one root or canal and 74 to 77 minutes for teeth with several roots or canals (Wong 2015, Bannister 2023). A crown often follows, which means more visits.

      How often should you get a cleaning?

      As often as your dentist suggests for you. Cleveland Clinic says most dentists recommend a cleaning every 6 months, and some people need them more often. For checkups, the UK's NICE guideline says the gap should be 3 to 24 months for adults and 3 to 12 months for under-18s, set for each person. The NHS says people with good oral health may need a checkup only every 12 to 24 months.

      NICE says your dentist should base the gap on how healthy your mouth is and your risk of problems. They look at your cleaning habits, fluoride, diet, tobacco and alcohol, health conditions such as diabetes, how past treatment went, and whether you can come at that interval. Tell your dentist sooner if something changes.

      What about the "every 6 months" habit? A 2020 Cochrane review found two trials with 1,736 people. In adults who already went regularly, checkups timed to each person's risk gave about the same results for decay, gum bleeding and quality of life as checkups every 6 months. Checkups every 24 months probably did about as well over 4 years, in adults their dentist judged suitable for that gap. There wasn't enough reliable evidence for children.

      How this tool works

      For each treatment, we use the typical time a patient information source gives (Cleveland Clinic, the NHS, the AAE, NHS hospital leaflets and dental schools), linked to its source. Then:

      • Time in the chair adds up each treatment's range. Where a source gives only an upper limit ("up to 90 minutes"), we add nothing to the low end. Fillings are added one by one, which may overstate the time when several are done together.
      • Time at the office adds 15 minutes for forms on a first visit and about an hour of recovery after IV sedation (King's College Hospital NHS). Waiting-room time isn't counted.
      • Visits: the low number assumes everything that can be done the same day is. The high number gives each treatment its own visits.

      We left out what we couldn't source: a full set of X-rays, impressions on their own (Cleveland Clinic says the material sets in a few minutes), consultations, and a same-day crown visit. Study averages (Bannister 2023, Wong 2015) are context only. Your office's times may differ. For what comes after, see When Can I Eat After Dental Work? and the Dental Numbness Calculator.

      The checkup part doesn't recommend an interval. It dates your next checkup from the gap your dentist gave you, saves it to My Smile only when you tap Save, and makes a calendar reminder. Share links include only the treatments you ticked, never dates.

      Frequently asked questions

      How long does a dental cleaning take?
      Most cleanings take 30 to 60 minutes, and special cleanings take longer (Cleveland Clinic). A checkup exam on its own is often shorter: an NHS dental center says routine exams usually last 20 to 30 minutes. A deep cleaning takes 1 to 2 hours, often over two visits.
      How many dental cleanings per year are recommended?
      Cleveland Clinic says most dentists recommend a cleaning every 6 months, and some people need more. For checkups, the UK's NICE guideline says your dentist should set the gap for you: 3 to 24 months for adults and 3 to 12 months for under-18s. A 2020 Cochrane review found that for adults who already go regularly, a gap based on their own risk worked about as well as every 6 months. Ask your dentist what suits you.
      How long does a new patient dental appointment take?
      Dental school clinics say a first full evaluation takes up to 90 minutes (Harvard Dental Center), and the University of Louisville books 90 minutes for it. Student clinic visits can last about 3 hours. Arrive 15 minutes early for forms. We found no trusted figure for private offices, which the schools say are quicker.
      How long does a filling take?
      In general an hour or less, and a simple filling may take as few as 20 minutes (Healthline, reviewed by a dentist). Large fillings and white (composite) fillings take longer. A regular filling is done in one visit; an inlay or onlay made in a lab usually takes two (Cleveland Clinic).
      How long does a root canal take?
      Most root canals take about 60 to 90 minutes (Cleveland Clinic), in one or two appointments (AAE). The NHS says appointments may last 1 to 2 hours, and treatment usually takes 2 or more. Molars take the longest. A crown often follows, which means more visits.
      How long does it take to get a crown?
      Usually two visits about 2 to 3 weeks apart, while a lab makes the crown (Cleveland Clinic). One NHS hospital says the first visit can take 1 to 2 hours and the fitting up to 1 hour. Some offices make same-day crowns in one visit, but they aren't for everyone.
