I am thinking about having my teeth whitened – where do I start? If you are considering having your teeth whitened, a consultation with your dentist can help you find out which teeth whitening option is best for you. While there are advanced technologies available to help many achieve an excellent result, there are limitations. Some stains need long-term whitening treatment and whitening cannot always achieve the ‘whitest white’ – so it is important to have realistic expectations. A lifelong white smile requires commitment.
