A crown or cap is a dental restoration which completely covers and strengthens an underlying tooth (above the gum line) that has been damaged or discoloured; this could be due to decay, trauma or large failed restorations. Crowns can often be used to improve the aesthetics of a person’s smile or can often be used to strengthen a weak tooth after root canal treatment. corwns
In the past crowns were generally made of a layer of porcelain over metal or gold alloy substructure, in more recent times crowns that contain no metal have become more popular due to cosmetic demands.
