What causes teeth sensitivity?

The various common causes of teeth sensitivity are discussed below:

Damaged Enamel

Our teeth comprise three layers, out of which enamel is the hardest and the outermost layer. The second layer is called dentin, and the innermost layer is the nerves and blood vessels of the teeth. Sensitivity occurs when the dentin is exposed. One common reason for dentin exposure is damaged enamel due to various reasons. The enamel can be eroded or worn out due to different causes. Let us discuss the reasons one by one that damage the enamel, leading to dentin exposure and teeth sensitivity. 

Teeth Grinding

Teeth clenching or grinding is a parafunctional habit that causes the wear and tear of the enamel. So what is the solution?

Nightguards are an effective solution to the problem of teeth grinding where the user wears these plastic plates that act as a barrier between the teeth to avoid contact with each other. However, understanding the root cause of teeth clenching is important before deciding the treatment. In most cases, stress is the chief cause of teeth grinding; hence, stress management techniques are advised along with nightguard therapy.

Aggressive toothbrushing

Brushing your teeth regularly is advised to keep optimum oral hygiene levels. But do you know aggressive toothbrushing can do more harm than good? Learning the correct technique of brushing is important to protect your teeth. It is advised not to use the horizontal scrubbing method to avoid enamel abrasion. The scrubbing method wears off the enamel, leading to sensitivity. Tooth-colored composite restorations are a classic solution to such enamel defects. 


Excessive consumption of acidic food items is a major contributor to enamel erosion. Carbonated drinks and excessive citrus content are common examples of acidic food items. The best way to prevent enamel erosion is to rinse away your mouth immediately with water after eating such foods. 

Gums recession

Apart from enamel damage, another common cause of sensitivity is root exposure due to gum recession. Receding gums is a common cause and requires immediate action. The tooth’s root portion is not covered with enamel, so it is more prone to tooth sensitivity. It is important to clinically examine the cause of gum recession and formulate a treatment plan. 

Excessive teeth whitening

Many over-the-counter whitening products like teeth whitening gels and toothpaste are available these days. Excessive use of these whitening agents can harm the enamel, leading to tooth sensitivity. It is in your best interest to opt for professional teeth whitening for a smile makeover. In-office teeth whitening is the safest and most effective way of lightening the color of your teeth by several shades in a single sitting.
