Tartar requires professional cleaning for removal. Tartar: If plaque is not removed, it mixes with minerals to become tartar, a harder substance.Plaque develops quickly on teeth after eating sugary food, but can be easily brushed off.

Plaque: A sticky, colorless film made of bacteria and the substances they secrete.

Plaque and tartar buildup can lead to gingivitis.

Gingivitis: Inflammation of the surface portion of the gums, around and between the crowns of the teeth.

Periodontitis: Inflammation of the deeper structures of the teeth (periodontal ligament, jawbone, and cementum).

Tooth decay: A general name for disease of the teeth, including cavities.

Most cavities occur on molars and premolars.

Cavities (caries): Bacteria evade removal by brushing and saliva and damage the enamel and deeper structures of teeth.

The root of each tooth descends below the gum line, into the jaw. The crown of each tooth projects into the mouth.

Wisdom teeth or third molars (4 total): These teeth erupt at around age 18, but are often surgically removed to prevent displacement of other teeth.

Molars (8 total): Flat teeth in the rear of the mouth, best at grinding food.

Premolars (8 total): Teeth between the canines and molars.

Canines (4 total): The pointed teeth just outside the incisors.

Incisors (8 total): The middlemost four teeth on the upper and lower jaws.

Periodontal ligament: Tissue that helps hold the teeth tightly against the jaw.Ī normal adult mouth has 32 teeth, which (except for wisdom teeth) have erupted by about age 13:.

Cementum: A layer of connective tissue that binds the roots of the teeth firmly to the gums and jawbone.

Blood vessels and nerves run through the pulp of the teeth.

Pulp: The softer, living inner structure of teeth.

When the enamel is damaged, heat or cold can enter the tooth through these paths and cause sensitivity or pain.

It is a hard tissue that contains microscopic tubes. Dentin: A layer underlying the enamel.Enamel is mostly made of calcium phosphate, a rock-hard mineral. Enamel: The hardest, white outer part of the tooth.Besides being essential for chewing, the teeth play an important role in speech. The teeth are the hardest substances in the human body.
