Some people have more than the full set of 32 permanent teeth. These supernumerary (extra) teeth may be found near the upper front teeth, near the wisdom teeth, or near the premolar teeth. They vary in size from small peg-shaped conical teeth, to full-sized teeth just like regular teeth; occasionally, they may even be super-sized. If the rest of the dentition is well aligned and not damaged by decay or fillings, these extra teeth are usually removed. If the extra teeth are embedded, surgery is required; otherwise, they can be simply extracted. If these extra teeth are well-formed, they can be used to replace adjacent teeth that have been damaged by tooth decay.
