It all depends on your oral health and other health factors such as diabetes and smoking. The American Dental Association suggests that the frequency of your regular dental visits should be tailored by your dentist to accommodate your current oral health status and health history. Many people can benefit from "Twice-yearly cleanings“ as recommended by many dentists. Most dental insurance plans will cover two dental cleanings per year. It’s always far less expensive to prevent a dental issue than try to fix it. If your teeth are prone to cavities and plaque build-up, which could lead to gum disease and eventual tooth loss, your dentist may even recommend a deep cleaning in addition to having a regular teeth cleaning every 4 months. Your dentist should be able to tell you how often you should have a dental cleaning.
