Deciduous (baby) teeth are typically whiter than the adult teeth that appear later. As we age, our adult teeth often become darker, yellower, or stained. This is partly why white teeth make people look more youthful. The main causes of darkened teeth are genetics, antibiotics, and certain foods and tobacco.
Our office uses take home whitening trays which are custom fitted to your teeth. A specialized whitening gel is placed inside the trays and worn for up to 30 min a day for typically 10-14 days. Periodic touch up whitening can be done every few months to keep the desired shade. Brief cold sensitivity is one of the most common side affects which is easily treated with sensitive formula toothpastes before and sometimes after treatment for a short time.
