We all want to look our best, and often, our smile makes a huge difference in how we feel about our appearance. However, even if you take good care of your teeth, they can become discolored for many reasons. Genetics can play a role in tooth color and how quickly tooth enamel discolors. Some discoloration takes place naturally with age. Trauma to the teeth, illness, medication, and exposure to certain foods, beverages, and tobacco can also cause discoloration. If your teeth are discolored, tooth whitening may help!
