Common Causes of Tooth Sensitivity

Common Causes of Tooth Sensitivity

What is tooth sensitivity? When taking cold or hot foods and drinks, make you say ‘ouch,’ meaning you are suffering from tooth sensitivity. You cannot take in slightly cold, hot, or acidic foods because tooth sensitivity causes discomfort in your teeth and gums.

Even tooth sensitivity is also triggered by taking in cold air. The pain caused by tooth sensitivity is sharp that suddenly runs into your nerve endings.

Tooth sensitivity is one of the most common dental problems, but it is curable and treated through different medications and procedures. Before getting any dental solution, you need to understand the leading causes of this dental problem.

There are a few common causes for tooth sensitivity and if you’re experiencing pain, it may be due to one of the following sensitive teeth causes.


Brushing too aggressively and frequently with a hard-bristles toothbrush is the most common cause of tooth sensitivity. Aggressive brushing removes the protective enamel of your teeth, ultimately exposing the microscopic hollow canals that lead to the tooth nerve.

Thus, your teeth with no protective layer become sensitive to cold, hot, or acidic foods. To be on a safer side, always use a soft-bristled toothbrush and do not plunge into cleaning your teeth right after you have taken an acidic food; instead, brush your teeth after half an hour is an approved method.

Gum Diseases

The gum diseases like gingivitis and periodontitis are also the major contributing factors towards the sensitive tooth. Ignoring the minor gum diseases like inflammation and tenderness can lead to severe problems like periodontitis that damage your gum tissue and bone support of your teeth. Moreover, when a gum starts receding, it exposes the soft root of your teeth, ultimately leading to extreme tooth sensitivity.

Cracked Tooth

A cracked tooth perhaps causes an extreme level of sensitivity in your teeth. This causes you severe pain and sudden discomfort while biting and chewing.

Excessive Use of Acidic Foods

It will wash away the protective enamel from your teeth. If you take too many acidic foods like soda containing drinks, tomato sauce, lemon, grapefruit, kiwi, and citrus-containing products, ultimately exposing the sensitive part (soft root) of your tooth.

Teeth Grinding

Frequent and long-time teeth grinding cannot only remove the enamel of your teeth, but in severe cases, it can also cause little cracks on the upper side of your teeth. As a result, your teeth become more sensitive to acidic, hot, and cold foods.


Too much of the plaque on the surface of your teeth causes the enamel to get eroded. Consequently, this creates more sensitivity and sudden discomfort and pain in your teeth. The only solution is to visit a dentist at Cal Dental Group so that you can get the right treatment through effective dental procedures.

Dental Treatment

Sometimes getting a dental treatment like a root canal, a tooth removal, or a crown placement can also become the cause of your tooth sensitivity. However, this kind of sensitivity usually starts diminishing as your teeth start being recovered from dental procedures. These are a few causes of tooth sensitivity; there might be some other that your dentist may tell you after examining your teeth in detail.
