Dentistry Vocabulary — FAQ
A cavity is a hole in a tooth caused by tooth decay. It forms when acids produced by bacteria in plaque break down the tooth's hard surface. If untreated, a cavity can grow larger, cause pain and lead to infection, so dentists usually repair it with a filling.
Enamel is the hard, white, outer layer that covers and protects each tooth. It is the hardest substance in the human body, but it can be worn away or damaged by acid and decay. Once enamel is lost, the body cannot grow it back, so protecting it is important.
A filling is a material a dentist uses to repair a tooth damaged by decay. After removing the decayed part and cleaning the cavity, the dentist fills the space with a material such as composite resin or amalgam to restore the tooth's shape and function.
Humans have several types of teeth: incisors at the front for cutting and biting, canines (the pointed teeth) for tearing, premolars for crushing, and molars at the back for grinding food. Each type has a shape suited to its job in chewing.
A tooth extraction is the removal of a tooth from its socket in the jaw. A dentist may extract a tooth if it is badly decayed, damaged, infected or overcrowded, or to prepare for braces. The area is usually numbed first so the procedure is not painful.
Plaque is a sticky, colourless film of bacteria that constantly forms on teeth. If it is not removed by brushing and flossing, it can harden into tartar and lead to cavities and gum disease. Good oral hygiene helps keep plaque under control.
A crown is a cap shaped like a natural tooth that is placed over a damaged or weakened tooth to restore its shape, strength and appearance. Crowns are often used after a large filling, a root canal or when a tooth is cracked.
A root canal is a dental treatment used to save a tooth when the soft tissue inside it, called the pulp, becomes infected or inflamed. The dentist removes the infected pulp, cleans and disinfects the inside of the tooth, then fills and seals it.
Incisors are the flat, sharp-edged teeth at the front of the mouth used for cutting and biting food. Molars are the larger, flatter teeth at the back used for grinding and crushing food. They work together to prepare food for swallowing.
Dentures are removable artificial teeth that replace missing natural teeth and the surrounding tissue. They can be complete, replacing all the teeth in a jaw, or partial, replacing only some. Dentures help people chew, speak and smile with confidence.
