Dental restorations repair or replace tooth structure lost through decay, trauma, or wear. Understanding why a tooth is restored and how it is prepared helps explain the choices made during treatment.
A dental restoration aims to return a tooth to useful function, structural integrity, and an appropriate shape. Restorative materials may also seal or replace tooth structure around implants, or be used after procedures such as root-canal therapy.
