Dental Crown Lightening
Most crowns are made from porcelain or composite porcelain. According to the whitening treatments do not work on these types of materials. However, they will remain the colour they were when your dentist put them in. So if you notice that your natural teeth are yellowing or developing stains, your goal is to whiten those teeth, so they more closely match your whiter crown.
When a dentist puts in a crown, they are careful to make sure it matches the natural teeth' colour. Life happens, and over time, your natural teeth may begin to yellow or stain. Your crown does not. So it could look whiter than the surrounding teeth. Fortunately, your crown won't discolour like natural enamel.
If you want to whiten your teeth and have one or more crowns, talk to your dentist to find out the best treatment options to make and keep your smile bright.
