Crowns are dental restorations which can cover the natural teeth that have been damaged. They are made out of porcelain and are cemented permanently on top of the teeth in need.
This refers to covering the tooth surface with a composite material to repair and change the colour and/or shape of a tooth. It is also sometimes called composite veneers.
Teeth Whitening and Bleaching
This is a process that teeth are bleached 2 to 3 shades lighter to their original colour. Bleaching will not whiten porcelain crowns or composite fillings and bondings.
A filling is a restorative process that removes decay and bacteria from a rotten tooth. The cleaned tooth is obturated with a white/composite filling to prevent further decay and restore function.
