A great way to make your dental cleaning less painful is to set a signal for your dentist. You can do this by raising your hand. The dentist will know what to watch for, but you should still try to make the appointment as pain-free as possible. It is important that you brush your teeth at the beginning and end of your day to prevent plaque build-up. Also, it is important to floss your teeth regularly, especially if you have periodontal disease or gum disease.
