Receding gums is when the gum tissue around a tooth is lowered resulting in an exposure of the root surface of the tooth. This exposure can lead to sensitivity and in some severe cases pain. Root surface is very delicate and unlike enamel which can resist brushing. If the exposed root surface is brushed too hard then it may lead to a cavity on the side of the tooth.
Gum Graft is a surgical procedure that helps strengthen and restore the height of the gum that has been lost due to gum recession.
