What Causes Tooth Sensitivity?

Posted on: December 15, 2018

Dental InfoTooth sensitivity is very common among many people. For many people, avoiding extremely cold or hot foods and drinks is the easiest way to avoid the sensitive feeling. However, knowing what the causes of this uncomfortable feeling are may aid in the prevention of continuous sensitivity.

While the causes of tooth sensitivity range from different dental problems to a person’s daily routine, being aware of the different causes can be beneficial to a person seeking to prevent future sensitivity.

Causes of tooth sensitivity

Worn down enamel

The enamel is the outer surface of the tooth. It protects and shields the interior of the tooth from diseases and erosion. However, when the enamel is worn down, it creates hypersensitivity to the tooth itself. Because the enamel acts as a shield, when it is worn down it will cause the interior of the tooth to be more exposed. This makes the teeth prone to sensitive temperatures.

Using too rough of a toothbrush can wear the enamel down, as well as brushing too hard. When the bristles over brush the enamel, it will eventually erode the protective layer that is needed for the exterior of the tooth.

Acidic foods and drinks

Almost everyone knows consuming foods or drinks that are highly acidic can be detrimental to the teeth and gums. But, most may not know that highly acidic beverages like soda or juices can also cause erosion to the teeth, which leads to sensitivity. Citrusy foods and processed meats also contain a lot of acidic ingredients which will also cause erosion.

Be sure to brush the teeth when consuming these highly acidic foods and drinks. Doing so will ensure that sensitivity to the teeth will stay at a minimum. Otherwise, constant consumption of these without proper cleaning will cause the pathways to the nerves to be exposed leading to sensitivity.

Teeth grinding

Constant grinding of the teeth can be extremely harmful to the mouth as a whole, but especially with that of sensitivity to the outersurface of the teeth. Although this typically occurs when a person is sleeping, it does do a lot of damage to the enamel of the teeth. Continuous grinding for long periods of time wears the enamel thin and exposes the dentin which is where many nerves lie. Once the nerves are exposed, the teeth are prone to feeling everything – including hot and cold temperatures.

Dental procedures

After a person undergoes a dental procedure, they likely experience sensitivity to extremely cold or hot foods and drinks. The sensitivity is temporary and not something to be too concerned about. Dental procedures that include bleaching, lasering, or drilling are more likely to cause sensitivity after the procedure is complete.

Tooth sensitivity can cause a lot of discomfort to people. Being aware of the different causes will aid in avoiding the sensitivity to form. There are many ways to prevent tooth sensitivity as well as ways to treat it once it occurs.
