Tooth hypersensitivity is a common problem that is characterized by sharp and sudden pain when exposed to hot, cold, or sweet foods, drinks, or air. It is a condition in which certain areas of the mouth become painful or uncomfortable when exposed to certain temperatures, foods, and drinks. 

This pain can range from a light, tingling sensation to a more intense, sharp pain that may only last for a few seconds. The sensitivity can occur in specific areas in the mouth, or it can be felt throughout the entire mouth. It can also vary depending on the time of day or year.

Let’s take a look at some possible causes of tooth sensitivity.

1) Regularly Consuming Acidic Food and Drink

Acidic foods and drinks can be a major contributor to tooth hypersensitivity. While they may taste great and be a part of a healthy diet, acidic items like orange juice, soda, tomatoes, red wine, coffee, fruit juices and soft drinks can erode the enamel on your teeth and cause tooth sensitivity. 

The enamel is the protective layer of your teeth and helps to keep them safe from the food and drinks that we consume. When the enamel is weakened, it can no longer provide the same level of protection and can lead to sensitivity. 

2) Brushing Too Hard

Brushing your teeth too hard can cause the enamel to wear away, leading to sensitivity. It is important to use a soft-bristled toothbrush and to brush gently. 

Constant brushing with too much force can damage the enamel layer of the teeth, leading to the dentin underneath becoming exposed. This can cause an uncomfortable level of sensitivity to heat, cold, and sweet foods.

3) Tooth Decay

Tooth decay, also known as dental caries, is caused by bacteria in the mouth that feed on sugar, creating an acid that erodes the enamel of the tooth. As the enamel erodes, the dentin underneath becomes exposed, leading to increased sensitivity.

Regular brushing and flossing can help to prevent tooth decay by removing bacteria from the mouth. Additionally, it is important to limit sugary foods and drinks, as well as to visit the dentist for regular checkups and cleanings.

4) Gum Disease

Gum disease, also known as periodontal disease, is an infection of the gums that can cause inflammation, bleeding, and even tooth loss if left untreated. It is caused by a buildup of plaque and bacteria in the mouth that irritates the gums.

Gum disease causes the gums to pull away from the teeth, leaving the roots exposed. This can lead to pain and discomfort when the exposed roots come into contact with the inside of the mouth, resulting in sensitivity in the teeth.

5) Bruxism

Bruxism is the medical term for grinding or clenching of the teeth. It is a common condition that affects many people and can lead to serious oral health problems if left untreated. It is usually caused by stress or anxiety and can be a symptom of a more serious underlying condition.

Bruxism can cause teeth to become worn and cracked, leading to sensitivity and pain. It can also cause the muscles of the face and jaw to become sore and tight, resulting in headaches and facial pain.


Tooth sensitivity can be caused by several factors, such as gum disease, tooth decay, acidic foods and drinks, and more. If you experience tooth sensitivity, it is important to speak to your dentist to identify the cause and the most appropriate treatment.
