The sensitivity in the teeth is something that affects several people. It is usually caused by eating or drinking something hot, cold, sweet or sour. Under normal conditions, the underlying dentine of the tooth (the layer directly surrounding the nerve) is covered by the enamel in the dental crown, and the gums surrounding the tooth. Over time, the enamel coating can become thinner, thus providing less protection. The gums can also retract over time, exposing the surface of the underlying root of the dentin. Dentin contains a large number of pores or ducts that run from the outside of the tooth to the nerve in the center. When the dentin is exposed these ducts can be stimulated by changes in temperature or certain foods.




What causes it?

Dentine exposure can occur due to several factors. Some of the most common reasons are:


Gum retraction due to age or inadequate tooth brushing

The consumption of acid beverages (such as carbonated water), which cause enamel erosion and dentin exposure

The grinding of teeth - in fact, this can cause a person to feel sensitivity in most, or all, of the teeth

Brushing with a very abrasive toothpaste, brushing incorrectly and / or brushing more than three times a day could result in the loss of enamel

Gum disease, which can cause gum retraction

A chipped or broken tooth can expose dentin

In addition, some dental treatments can cause sensitivity. It is known that treatments such as teeth whitening, professional dental cleanings, the placement of dental braces or a dental filling cause sensitivity during or after the procedure.


What can I do about it?

The first step in doing something about sensitivity in the teeth is to find out what is causing it - a dental health professional can help you with this. If the sensitivity is due to the exposed dentin, there are several steps that you, like your dental health professional, can take to reduce sensitivity. These may include:


Use a very soft bristle toothbrush

Brush properly to help prevent enamel abrasion and gum retraction

Use a specially formulated toothpaste to help reduce sensitivity

The dental health professional can:

Apply a fluoride varnish on sensitive areas to help strengthen the tooth

Recipe a toothpaste with high concentration of fluoride to use every day

Place a dental restoration to strengthen the areas that have lost the enamel

In the end, whether you need a procedure at the dental clinic or products without a prescription, the most important step is to visit a dental health professional so that he or she can determine the cause of tooth sensitivity and help you Find a solution that works.
