In addition to oral hygiene at home, it is necessary to have your teeth cleaned at least every six months. Brushing, flossing, and rinsing help, however, a professional cleaning will attend to the areas that you miss. During the cleaning, your hygienist will also inform you on how to take good care of your teeth, answer questions, and inform you on products available that are specific to your needs. During the cleaning, bitewing x-rays are taken at a recommended interval specific for you. A full mouth set of x-rays is often made every 5-7 years. The dentist should also do an exam every six months.
