Tooth Hypersensitivity is a general dental problem that can occur over time as an effect of receding gums and enamel wear. It begins to happen when the softer, inner part of the tooth called ‘dentine’ becomes exposed. Dentine lies under the enamel and the gums. Thousands of microscopic channels go through the dentine towards the center of the tooth. Once the dentine is exposed, external triggers (such as a cold drink or ice cream) can stimulate the nerves inside the tooth, resulting in the characteristic short, sharp sensation of tooth sensitivity.
Myth 1: Cavities cause Tooth Hypersensitivity.
Fact: This is true, but not all the time. Tooth decay causes sensitivity, but one may also experience sensation without it. Tooth sensitivity primarily occurs when the enamel of the tooth gradually wears away, exposing softer tissue called dentine.
Myth 2: Only cold food causes sensitivity.
Fact: When exposed dentine comes into contact with anything hot, cold, sweet, or sour, it can trigger the nerves and cause a short sharp sensation.
Myth 3: Tooth sensitivity is temporary.
Fact: The sensitivity may come and go, but if left untreated, it can get in the way of your everyday life.
