Saving Your Tooth by Restorative Dentist in ASH Dental Irvine. As a restorative dentist, we specialize in saving teeth that may otherwise need to be pulled. It is incredibly common to damage a tooth, sometimes doing the most basic of activities. Driving a car and getting into a wreck, playing basketball, and colliding with an elbow, running into something at work, etc.; all these things can lead to tooth damage.
