What causes sensitivity?
Sensitivity is the result of the dentin section of the tooth becoming exposed. The dentin lies beneath the outer enamel layer of the tooth and it contains the pulp tissue; this is the living tissue of the tooth and includes the blood vessels and nerves. If the enamel is weakened, eroded or damaged, the dentin becomes exposed.
The enamel becomes thinner as a result of general wear and tear, but this process can be accelerated by your diet, brushing too hard and teeth grinding. Acidic foods and drinks, such as wine, juices and salad dressings can contribute to erosion of the enamel.
What happens when you have sensitive teeth?
Tooth sensitivity causes you to feel pain, usually when you eat or drink something hot or cold, like a hot drink or an ice cream. You may also suffer pain when your teeth are exposed to cold air or when you bite on something that has a sharp taste, such as an apple. Sensitivity can range from mild to severe.
What should I do if I have sensitive teeth?
Many people get mild sensitivity from time to time, but if you have severe pain or you have pain on a regular basis, it is likely that there is an underlying cause. Sensitivity is often a symptom of tooth decay and we recommend seeing your dentist, so that they can have a look at your teeth and check for potential problems; if you do have a cavity, the tooth can then be filled before the issue gets any worse.
