Even when you brush and floss regularly, your teeth can become discolored due to many external factors. Some of these factors include:
Drinking tea and coffee
Smoking
Use of certain medications
These external factors can wear down the enamel and the tooth surface becomes open and vulnerable to yellowing. Faster tooth discoloration also has genetic roots. For example, many of our patients have naturally less enamel or their enamel is more likely to wear faster.
