Dentures, also known as false teeth, are prosthetic devices constructed to replace missing teeth; they are supported by the surrounding soft and hard tissues of the oral cavity.
The dentist will look at all of your teeth and check your gums to make sure they're strong and healthy. The dentist will also check the way your top and bottom teeth work together. This is called your bite. If there might be a problem with your bite, you may be referred to an orthodontist (say: or-tho-DON-tist).
