Over time, the outer layer of our tooth enamel deteriorates and this reveals a dark or yellow shade. Lifestyle factors can also play a part in tooth discolouration. For example, drinking coffee, tea or red wine, and tobacco use. Yellow or discoloured teeth are considered the top aesthetic concern of many patients. Not only is teeth whitening considered a simple and non-invasive treatment but it can dramatically change the colour of your teeth. You can schedule a consultation with your dentist to discuss teeth whitening further.
