Tooth discoloration is a natural part of the aging process because enamel gets thinner from daily wear and tear. Genetics, poor oral hygiene, foods and drinks, and smoking can also affect teeth color. Patients concerned about discoloration often turn to store-bought whitening products, but that’s risky because not all stains are equal.
