What’s better than a beautiful smile? With perfectly whitened and maintained teeth you can talk confidently to everyone. This is the reason that tooth whitening is one of the most famous dental treatments. As the saying goes “no pain no gain,” but whitening is something which can bring you countless benefits without any traumatizing dental procedure. Unlike other dental procedures, whitening is vey cost effective and has no side effects. Although whitening is a simple procedure, it can be a bit challenging if the tooth to be whitened has already been subjected to a major surgery or injury.
Dental trauma refers to any dental injury caused by an external factor
Dental damage encompasses all injuries like broken teeth which are caused accidentally or during a prior orthodontic procedure. According to recent studies, more than a quarter of the US citizens have suffered from minor to major dental injuries. However, a number of people don’t know that injured teeth can react to chemicals used for whitening. It does not mean that a traumatized tooth cannot be whitened, but it might require additional treatment.
The first and the most important step in whitening damaged tooth is figuring the root cause of discoloration
Dentists conduct x-ray tests to examine whether the tooth pulp is vital or not. In case of vital pulp, bleaching can generate effective results. You can either go for in-office or take-home tray methodology, but usually dentists recommend office treatment for effective and quick results.
However, in case of injured teeth, pulp nerves are not vital. A patient has to go through pre-whitening treatment (usually root canal) to remove dead cells. It is important for preventing probable reactions caused by bleaching and for long lasting results.
Traumatized teeth should be whitened from inside out
Usually the discoloration of traumatized teeth is due to some internal factor. The whitening procedure requires removal of debris from the tooth (by drilling the tooth). The tooth is then cemented to prevent bleaching agent contact with the tooth pulp.
The next step is bleaching. Sodium Perborate is placed in an empty chamber and teeth are bleached with it. You might require more than one round to reach the desired shade of white.
Although traumatized teeth can be bleached only externally, the results will not be long lasting. So for best results, go for pre-whitening treatment.
