What causes gum recession and can it be prevented?
Gum recession is the gradual loss or retraction of the soft tissue of the gums, eventually exposing the roots of the teeth. Unlike the visible part of your tooth, which is buffered by a hard coating of enamel, the roots are much more vulnerable. One of the first signs of gum recession is teeth that are highly sensitive to cold and heat at the gumline. Gum recession is a common problem, and if left untreated over time it can leave teeth more susceptible to cavities and infection.
