Is it ok if i have a dental exam once a year?

Probably: Frequency for dental exams is unique to each person. If you are a healthy adult with minimal dental problems once a year is often enough. Kids develop decay faster and should go more often. Those with periodontal disease need to go more often as well, often 3 or 4 times a year.

Maybe: Some of my patiebnts have such good dental health and hygiene that once a year is okay for them. Others, however, have situations that should be checked mor often than once per year. Ask your dentist what group you are in.

Patients that have excellent hygiene and minimal dental work as well as minimal plaque and tartar buildup can probably survive with a dental checkup once a year with the knowledge that they can always schedule a visit for emergency visits if the need arises.

One of the reasons for 6 month check-ups is that your teeth need to be cleaned in the places you can't, or don't reach. Failure to do so contributes to periodontal (gum) disease. If you brush 2x/day for 2 full minutes by the clock, floss or WaterPik every single day, have no existing gum or tooth disease, you may want to take the risk. If the answer is "no" to above, once a year won't cut it.
