Teeth Whitening Lombard, IL Dentist Your smile is one of the first things a person will notice when you meet. If you have stained, dull or discolored teeth, teeth whitening may be a great option for you. Even healthy teeth discolor over time. The main causes of stained teeth are genetics, antibiotics, tobacco and certain foods. As we age, our teeth darken as well. Teeth whitening is a simple and effective way to brighten your smile. You can look younger and feel more confident with a whiter smile. Your teeth and gums must be healthy enough for whitening. Before recommending whitening, we will carefully evaluate your smile.
