Ever wonder how dentists tell when all the decay is removed from a tooth? All dentists are taught to fel around with a sharp pick in order to determine if the tooth's density is soft or hard. Unfortunately, tactile ability and interpretations of "how soft is soft" varies between dentists.
In 1978, a special dye was developed in Japan that stains tooth decay. Dr. Alex Shvartsman utilizes this special dye, allowing him to eliminate the guesswork when it comes to decay. Dr. Shvartsman removes only the decay from a tooth with this conservative approach. In fact, he often finds decay under fillings and crowns that were accidentally left behind by other dentists!
