Patient had a crown done in his front tooth 10 years ago by previous dentist. The crown color may have matched the next one at that time but over the course of years, his natural dentitions has become more yellow while his crown hasn’t changed its color. Please note that whitening procedure will not whiten your crowns and other fillings. Patient had a zoom whitening done to get his bright teeth back and now have a good smile again with matching colors in two front teeth as well as other teeth.
