You have heard it your whole life: get your teeth cleaned twice a year. It is good advice for most people, but the honest answer is that the right schedule depends on your individual situation. Some people are fine with two cleanings a year. Some need three or four. Some new patients we see have not been to a dentist in over a decade and need a different approach entirely to get their mouth back to a healthy baseline.
I want to walk through how we actually decide what cleaning schedule makes sense for each patient, because the standard advice is not always the right advice.
Why twice a year became the default
The twice-a-year recommendation is not based on rigorous science. It started as a guideline in the early 20th century, partly based on what insurance was willing to cover, and partly because it was a memorable schedule. For people with healthy mouths and good home care, two cleanings a year does work well. The recommendation stuck.
For most patients with healthy gums, low cavity risk, and a solid home routine, two cleanings a year keeps things in good shape. Your hygienist removes the buildup that brushing and flossing simply cannot get to on their own. The exam catches small problems before they become expensive ones.
When more frequent visits make sense
There are several situations where every three to four months is the better schedule:
History of gum disease. Once you have had periodontal disease, you stay at higher risk for the rest of your life. The bacteria responsible for gum disease repopulate quickly, and more frequent cleanings, called periodontal maintenance, keep the bacterial load down before it can cause damage again. (You can read more about gum disease and how it progresses in our post on gum disease in Kittitas County.)
Diabetes. Diabetes and gum disease have a two-way relationship. Diabetes makes you more susceptible to gum infections, and gum infections make blood sugar harder to control. Diabetic patients often benefit from quarterly cleanings.
Tobacco use. Smoking and chewing tobacco both significantly increase the risk of gum disease, oral cancer, and tooth loss. More frequent cleanings, plus regular oral cancer screenings, are smart for tobacco users.
Heavy tartar buildup. Some patients form tartar quickly regardless of how well they brush. This is partly genetic and partly related to saliva chemistry. If you are a heavy tartar former, more frequent cleanings keep the buildup under control.
Pregnancy. Hormonal changes during pregnancy can cause gingivitis, sometimes called pregnancy gingivitis. More frequent cleanings during pregnancy, particularly in the second trimester, help manage this. Routine cleanings are safe during pregnancy.
Compromised immune system. Patients undergoing chemotherapy, on immunosuppressive medications, or with conditions that affect immune function need closer monitoring of their oral health.
Orthodontic treatment. Patients in braces or doing Invisalign should come in more frequently because cleaning around brackets and trays is harder. More cleaning visits during treatment prevents permanent damage to the enamel.
Why some people need less than twice a year
A small number of patients can stretch to once a year. Usually this is someone with excellent home care, no history of gum disease or cavities, low risk factors, and stable dental work. In those cases, an annual exam and cleaning is sufficient.
I do not recommend going longer than a year for most adults. Even with great home care, plaque hardens into tartar that brushing cannot remove, and tartar buildup along the gumline is what kicks off gum disease.
What actually happens during a cleaning
A standard prophylactic cleaning, sometimes called a prophy, involves:
Scaling. Your hygienist uses hand instruments and an ultrasonic scaler to remove plaque and tartar from above and just below the gumline. This is the part that takes the most time.
Polishing. After scaling, your teeth are polished with a slightly gritty paste to remove surface stains and smooth the enamel.
Flossing. Your hygienist flosses between every tooth to make sure nothing is missed.
Fluoride. Most adults benefit from a fluoride treatment, especially if you are at higher risk for cavities or have sensitivity issues.
Exam. I review the X-rays, look at your teeth and gums, check existing dental work, screen for oral cancer, and discuss any concerns.
A cleaning typically runs 45 minutes to an hour. A first cleaning for a new patient often runs longer because we need to do a comprehensive exam and X-rays.
Deep cleanings: when a regular cleaning is not enough
If you have not been to a dentist in years, or if you have signs of gum disease, you may need a deep cleaning instead of a standard cleaning. A deep cleaning, called scaling and root planing, goes below the gumline to remove tartar from the root surfaces of the teeth.
This is usually done in two appointments, one side of the mouth at a time, with local anesthesia to keep you comfortable. After a deep cleaning, you typically come in every three to four months for periodontal maintenance until your gums are stable, then we can talk about going to a regular schedule.
The real cost of skipping cleanings
I see this regularly. A patient comes in after three or four years away. What would have been a simple filling at the two-year mark is now a root canal or an extraction. What would have been mild gingivitis is now periodontal disease with bone loss.
Prevention is always cheaper than treatment. A cleaning costs a fraction of a filling. A filling costs a fraction of a crown. A crown costs a fraction of an implant. By the time decay reaches the nerve of a tooth, you are looking at root canal therapy plus a crown, which can run into the thousands.
The same is true for gum disease. Mild gingivitis is reversible. Moderate periodontitis can be managed but not reversed. Severe periodontitis leads to tooth loss.
This is not me trying to sell you on cleanings. It is just true.
What we recommend
At your first visit, we will assess your gum health, cavity risk, and overall oral health, and recommend the schedule that makes sense for you. Some patients are fine at twice a year. Some need more frequent visits, at least temporarily.
If you have been away from the dentist for a long time, do not let that stop you from coming in. Whatever shape your teeth are in, we have seen worse. We will look at where you are now, talk through what needs to happen, and figure out a path forward together. There is no shame in falling off the schedule. Life happens. The important thing is getting back on track.
