This is an option that is making adults smile even before their teeth are perfect. These are transparent aligners – similar to clear gum shields – which, when worn, will adjust tooth alignment over time. These are replaced every two weeks. Besides the fact that they are wonderfully see-through, you can remove them to eat and brush teeth.

Chipped, broken, discolored or decayed teeth may be repaired or have their appearance corrected using a procedure called composite bonding. A dental composite material with the look of enamel and dentin is applied into the cavity or onto the surface of a tooth, where it is then sculpted into shape, contoured and hardened with a high-intensity light. The result is a restoration that blends invisibly with the remainder of the surrounding tooth structure and the rest of your natural teeth to create a healthy, bright smile.
