Routine check-up and cleans are the best way to keep a healthy smile. As a general recommendation the interval between a check-up is 6 months. Many people tend to visit the dentist only when they are in pain or they have a dental emergency. In this case, the treatment is often major and costly, which could have been avoided if there was an early intervention. Keep your costs down and your oral health up, by visiting your dentist every 6 months.
