Dr. Yu and his staff are efficient, friendly, and ultra-competent. Turned out I needed to have a crown replaced, as the tooth was cracked under it and the crown eroded. I am not an easy patient--I can't have epinephrine, which means it's harder to get me numb, and I've been to dentists who simply couldn't--but she did great. The temp that was put in is a masterpiece, fits so well i forget it's there. I go back soon for the crown itself, and for a quadrant of deep cleaning--yes, they do that in-house not send out to some high-priced perio. Hygienist who cleaned my teeth was excellent too.
