Abstract:
Supernumerary teeth are more common in the permanent than the primary dentition. In the latter, the majority occur in the maxillary lateral incisor region or as a mesiodens. Indeed, in one study conducted in the USA, all 26 cases of primary supernumerary teeth examined were found to be lateral incisors. This report describes a case presenting with three erupted supernumerary (supplemental) teeth in the primary dentition, including, somewhat unusually, bilateral duplication of maxillary canines.

Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
