You may assume you should have a dental check-up every 6 months, but some people may not need to go so often and others may need more frequent checks. Your dentist will suggest when you should have your next check-up based on how good your oral health is. The time between check-ups can vary from 3 months to 2 years, depending on how healthy your teeth and gums are and your risk of future problems. A check-up allows your dentist to see if you have any dental problems and helps you keep your mouth healthy. Leaving problems untreated could make them more difficult to treat in the future, so it’s best to deal with problems early, or, if possible, prevent them altogether. Generally, the lower your risk of dental problems, the longer you can wait before your next check-up. So people with good oral health will probably need to attend only once every 12 to 24 months, but those with more problems will need check-ups more often.
