Only a qualified dental professional can perform tooth-whitening procedures. It is your dentist who understands your dental needs and who can protect your oral health. The results of vital tooth bleaching can be quite spectacular; however, it may not be the choice of treatment for everyone. For example, if you have an anterior white filling or a crown, the bleaching process will affect the colour of the natural tooth but not the restorations. The results can then be disappointing. That is why if you are considering whitening your teeth, you should discuss this with your dentist to determine which method will suit your needs.
