The mesiodens is the most common type of Supernumerary teeth and is found between the two central incisors.

Paramolars are extra molar teeth, which are found either in the buccal or lingual aspect of the regular molars.

Distomolars are also extra molar teeth but are usually located distal to the third molars.
