My teeth have yellowed – why does that happen, and what are my options now for whitening them?
Tooth discoloration is a normal part of aging. As we get older, our tooth enamel wears down, and our teeth look dull. Our teeth also can become discolored from smoking or drinking lots of coffee or tea. Other causes of tooth discoloration include side effects of medications (specifically certain antibiotics) that are sometimes used during the developmental phase of the teeth. It could be your genetic makeup, or even excessive fluoride consumption (fluorosis, seen in both children and adults). Teeth whitening and veneers are two options for those who have dull or discolored teeth.
