Teeth can become discoloured for a number of reasons, and often the effect is temporary and can be attributed to food or drink, such as coffee, red wine or beetroot. Smoking also causes teeth staining, resulting in a nicotine smile that won’t see you dazzling anybody with your pearly whites. In addition, however, there are several diseases that can affect the tooth enamel and underlying dentin. If a nerve dies within a tooth, the tooth will darken as the nerve sheds material into the dentin. The tooth can be capped to cover the discolouration, or a bleaching solution can be utilised to whiten it. A number of other conditions can contribute to wider tooth discolouration, such as certain antibiotics and chemotherapy.
