Apart from the makeup, teeth whiteness is also their concern. To maintain the brightened and white teeth, a lot of them will avoid consuming food or drinks which can stain the teeth, such as coffee, tea, red wine and curry. What they do not know is that other than diet, medication can also stain the teeth. If discolouration is caused by diet or smoking, we can still treat it with the usual teeth whitening methods. But staining caused by medication can be difficult to reverse. The antibiotics tetracycline, which is used for fighting bacterial infections and severe aches, is proved to be one of the culprit of teeth discolouration. If pregnant women or children under the age of 12 use tetracycline, it will bind to and settle into the calcium in the teeth. After exposure to light, the affected teeth will gradually turn into a darker colour permanently. In recent year, the researchers have developed a new generation tetracycline antibiotics. U.S. Food and Drug Administration has approved the use of this medicine for acne treatment. It has proved to have a lower binding affinity with calcium, hence a lower chance of teeth staining caused by mediciation.
