Tooth sensitivity is something that affect
s many of us. In this 2 part series
I’ll answer many of the questions you
might have regarding this often
WHAT IS DENTIN HYPERSENSITIVITY?
Dentin hypersensitivity, more commonly
referred to as sensitive teeth, can
be defined as short, sharp pains that
come from exposed dentin (the layer of
tissue found beneath the hard enamel
that contains the inner pulp).
Individuals with sensitive teeth may find
that the pain can be triggered by
hot, cold, sour or sweet beverages or foods, forceful brushing or flossing, or
even by cold air.
WHAT CAUSES THE SENSITIVITY?
Tooth sensitivity is caused by the movement of fluid within tiny tubes
(pores) located in the dentin, which results in nerve irritation. When the hard
enamel of a tooth is worn down or gum
s have receded, the surfaces of these
tiny tubes can be exposed, resulting in pain while eating or drinking certain
foods, such as ice cream or cold coffee.
HOW COMMON IS THIS CONDITION?
Dentin hypersensitivity is one of the
most common complaints among dental
patients. One in five people in
North America experience dentin
hypersensitivity at some point in his or her life.
