A dental exam is a checkup for your teeth and gums. A dental exam should be performed every six months for both children and adults. Maintaining good oral hygiene is crucial. Leaving problems untreated can lead to serious problems that can be painful. By examining your teeth, you can detect tooth decay, gum disease, and other oral health problems early, when they are easier to treat. The exams are also used to educate people about how to care for their teeth and gums.
