What is Sensitivity Problem in Teeth and Why Does It Occur?

Sometimes you feel a strange aching in your teeth and you may not understand why. This situation happens to many people, especially when consuming hot and cold foods or when you consume hot and then cold foods one after another. Studies have revealed that the problem of sensitivity in teeth is especially experienced by individuals between the ages of 20 and 50. Tooth sensitivity can occur when a layer called dentin becomes irritated and damaged over time. This is exactly why the tingling you feel in your teeth while consuming hot or cold foods may occur.

Why Does Sensitivity Problem In Teeth Occur?

There may be more than one reason for the sensitivity problem in teeth. Generally, the problem of a single tooth or situations that are missed in the dental care routine causes an increase in sensitivity. Let’s examine a few different reasons with you.

Receding Gums

Under normal conditions, the uppermost parts of the teeth are covered with gums and are therefore protected. However, inflammation of the gums, irritation of the gums, or other similar conditions cause receding gums. In this case, a certain part of the upper part of the tooth will remain unprotected. This part was not as durable as other areas of the tooth. The fact that this area, called the dentine layer, remains unprotected in this way may cause sensitivity to cold or hot foods. Intense pain becomes more difficult with sensitivity.

Hard Brushing of Teeth

Damage to the gums can also cause various gum problems in the long run. For example, various medical problems may occur, sometimes referred to as gingival recession or tooth erosion. Brushing the teeth too hard or too quickly increases the pressure on the gums as a result of abrasion. This causes damage and erosion of the dentine and enamel layer of the tooth. This condition, which is also called a gingival recession or tooth erosion, causes the root surface of the tooth to emerge. This surface does not have a sufficiently high level of protection as it was previously under the gum. The sore of the teeth during the person’s consumption of drinks or food or in the case of cold air hitting his face can be called sensitivity. The main reason for the stinging here is the unprotected exposure of the root area to hot or cold heat. This is exactly why the sensitivity arises.


Tooth sensitivity and pain can negatively affect a person’s biological, physiological, professional, and cultural life in the long run. In gum recessions caused by hard brushing of the teeth, the bones that hold the teeth under the gums and around the teeth may also melt. This situation can cause the shaking of the teeth or the formation of aches and pains in the teeth. In addition, hidden bone losses in the mouth area may occur as a result of this situation.


After Dental Filling

It is known that dental sensitivity is a very common problem for many patients. Dental filling procedures made at the initial stage of dental caries may cause sensitivity especially when drinking something very cold or exposed to cold air. However, this situation can be solved easily. Progression or deepening of tooth decay causes the nerves in the relevant area to become sensitive when the cavities are cleared during filling. The filling made immediately after this cleaning results in the emergence of sensitivity. If you only have cold sensitivity, this will go away about a month after the tooth filling is completed. However, if you experience the same sensitivity problem for both hot foods and cold foods, it may be a good idea to cancel the filling treatment and perform dental canal treatment instead.

After Root Canal Treatment

In root canal treatment or canal filling, your dentist performs the following procedures: First, the dead or inflamed nerves in the root of the tooth should be removed. Then, the root should be expanded in the tooth canal very carefully and a very clean surface should be obtained. The emptied areas that are cleaned afterward are filled with dental sticks in order to prevent any leakage. A dental filling can be performed after root canal treatment and dental filling. In this way, it is possible to ensure dental integrity. Sensitivity may be experienced during the first days after tooth filling, especially during chewing. However, within a week, the chewing activity becomes more comfortable and it is aimed to eliminate the chewing pressure within a month.

You Should Pay Attention To Teeth Whitening Products

Some of the tooth whitening products can contain peroxide and soda material. These materials can damage the upper surface of the tooth in long-term use. This situation can cause sensitivity later on. Do not use teeth whitening products other than the advice of your dentist.

Teeth Grinding

Do you unconsciously grind your teeth while you sleep? Hey, this could be hurting you seriously. Grinding teeth creates a serious problem on the protective layer of the tooth and this problem causes tooth sensitivity. Because the protective layer on the tooth is damaged and the sensitive nerve endings of the tooth begin to interact directly with food.

Dental Inflammation

Flossing regularly can prevent food residue from accumulating around your teeth and gums. But if you do not use it, micro bacterial residues accumulate around the tooth over time, and these harden with saliva. This hardening structure interacts with the acids of the new nutrients over time, and the resulting situation is extremely harmful to both your teeth and gums. Damage to the layer protecting the tooth area causes sensitivity.
