STRUCTURE OF A TOOTH: (longitudinal section)
Any of the hard, bony conical structures of the upper and lower jaws used for chewing. A tooth consists of a crown portion above the gum, a root portion embedded in a socket (alveolus) of the jaw bone, and a neck or cervical constricted region between the crown and root. The soft-tissue gingiva covers the neck and root to a variable extent, depending on age and oral hygiene. The major portion of a tooth consists of dentin, which is harder than bone; enamel; and cementum, which is similar to bone. The pulp cavity contains the dental pulp. Each tooth has five surfaces: occlusal, mesial, distal, lingual, and facial or buccal. See: illustration; dentition

Everyone has two complete sets of teeth during his life. The 20 primary teeth are the first set of teeth a person develops. They exfoliate by age 14 and are replaced by the 32 permanent teeth. The permanent teeth include the following: incisors, canines (cuspids), premolars (bicuspids), and molars. On average, a child should have 6 teeth at 1 year, 12 teeth at 18 months, 16 teeth at 2 years, and 20 teeth at 12 years. Some children are born with a few erupted teeth; in other children the teeth may not appear until 16 months.

Patient care

Health care professionals should assess patients’ teeth and gums during physical examinations, educate patients about routine dental hygiene (brushing, flossing, gum stimulation, use of oral rinses), and refer them to a dental professional for dental caries, eruption anomalies, or periodontal problems.

accessional tooth

A permanent molar tooth that arises without deciduous predecessors in the dental arch.

anterior tooth

The central and lateral incisors and/or the canines, located adjacent to the midline of the maxilla or mandible.

baby tooth

Deciduous tooth.

bicuspid tooth

A permanent, premolar tooth. There are eight premolars, two in each quadrant (four in each jaw) between the canines and molars. Premolars have two or three cusps on the occlusal surface.

DECIDUOUS TEETH (LEFT SIDE)

deciduous tooth

Any of the 20 teeth that make up the primary dentition, which are shed and replaced by the permanent teeth.
Synonym: baby tooth; milk tooth; primary tooth See: illustration

hypersensitive tooth

A tooth sensitive to temperature changes, sweets, or percussion. It may exhibit gingival recession, exposed root dentin, caries, or periodontal disease.

Treatment

Popular treatments for hypersensitivity include topical varnishes, sealants, and topical fluoride applications. Other treatments include application of silver nitrate, formalin, glycerin, strontium chloride, potassium nitrate, calcium compounds, sodium citrate, and potassium oxalate.

Patient care

The patient can reduce sensitivity by a regimen of plaque control, dentifrice with fluoride, self-applied fluoride, and control of diet.

impacted tooth

A tooth unable to erupt due to crowding by adjacent teeth, malposition of the tooth, or developmental disturbances.

malacotic tooth

A tooth soft in structure, white in color, and esp. prone to decay.

milk tooth

Deciduous tooth.

permanent tooth

Any of the 32 teeth that develop as the second dentition and replace the deciduous teeth.
Synonym: secondary tooth See: deciduous tooth for illus

primary tooth

Deciduous tooth.

sclerotic tooth

A yellowish tooth that is naturally hard and highly resistant to caries.

secondary tooth

Permanent tooth.

succedaneous tooth

In dentistry, a permanent tooth that succeeds (replaces) a normally erupted deciduous tooth. It includes the premanent incisors, cuspids, and premolars. The deciduous molars are replaced by the permanent premolars, which are not succedaneous teeth.

wisdom tooth

Any of the third most-distal molars on each side of both jaws. These four molars may appear as late as the 25th year or may never erupt.
