Crowns are used both for baby and permanent teeth. In children, crowns cover primary teeth that are too decayed for fillings. Crowns are also placed over teeth that are at high risk of decay.

Implants are often capped. Crowns are also used for cosmetic purposes, such as covering malformed or discolored teeth.
