Is it painful to treat cavities

To correctly answer the question “Is it painful to treat cavities?”, one should understand which type of cavity is being discussed. A cavity (caries) is a disease that occurs as a result of the destruction of hard tooth tissues under the influence of acids.

Types of caries

Stages of caries development

Depending on the type and stage of caries development, the likelihood of pain varies. There is a direct correlation: the greater the depth of tooth tissue damage from caries, the higher the probability and intensity of pain.

This is precisely why all doctors recommend seeking help at the first symptoms and not ignoring routine check-ups. In most cases, treating caries is painless when it is at the initial stage – there is no need even for anesthesia.

The absence of pain with superficial caries prevents patients from detecting it on their own. However, during a routine examination, the doctor can easily diagnose the onset of the disease and quickly eliminate it.

The second stage of the disease – moderate caries – is associated with partial damage to the dentin. Dentin is a softer tissue compared to enamel that contains nerve endings. The patient begins to experience pain and discomfort, which forces them to see a doctor.

The question “Is it painful to treat moderate caries?” is no longer so easy to answer definitively. Some patients experience only slight discomfort during treatment, while others face pain sensations, and the need for anesthesia arises.

At the third stage, when deep caries is involved, anesthesia is always used. An additional danger of deep caries development is that dentin damage can reach the nerve, leading to a condition called pulpitis. Its treatment will be more complex and involves tooth devitalization (nerve removal and canal filling).

We recommend that patients stop tormenting themselves with the question “Is deep caries painful to treat?” and not waste time on doubts. The sooner you see a doctor, the faster and cheaper they will relieve you of pain.

Treating caries between teeth (on approximal surfaces) has its own peculiarity: the doctor needs to place an isolation system (rubber dam). Installing such a system may cause the patient discomfort. Using wedges, matrices, and other instruments during treatment can also provoke unpleasant sensations.

However, this is not actually about pain, and the question “Is it painful to remove caries from approximal surfaces?” can be answered as follows: “No, but slight discomfort is possible.”

Cervical caries is associated with the destruction of the part of the tooth located between the crown and root (at the gum line). Both enamel and cement near the tooth root can be affected. Meanwhile, with cement caries, only the cement surface of the tooth root is destroyed.

Cervical caries can be of both moderate and deep degree, therefore it requires the use of good anesthesia. Cervical caries is painful to treat only in cases where additional factors influence the occurrence of pain.

Discomfort and pain that occur during caries treatment may be associated with:

• nerve irritation.

During the removal of damaged tissues, a nerve may be affected, which in turn provokes intense pain. Nerve irritation is possible during the treatment of deep caries;

• dentin sensitivity.

Removal of damaged tissues can provoke dentin sensitivity due to exposure of open tubules;

• tissue overheating.

During treatment of the affected area with a bur, tissue overheating is possible, which provokes pain;

• patient anxiety and stress.

Psychological factors can also influence the intensity of pain and its perception.

It should be noted that the presence of pain is not related to the location of the tooth. Therefore, all clarifying questions such as: “Is it painful to treat caries on front teeth?”, “Is it painful to treat caries on back teeth?”, “Is it painful to treat caries under a filling?” can be answered: “It depends on the degree of carious destruction.”

Modern dentistry uses the best anesthesia that guarantees good pain relief, does not cause allergic reactions, and is suitable even for pregnant women, as it does not penetrate the hematoplacental barrier. However, human physiology is quite complex, and there are things that even modern anesthetics cannot overcome.

In the coronal part of the tooth, beneath odontoblasts (cells involved in tooth formation), lies the Weil zone. It contains blood capillaries and nerve fibers (Raschkow plexus). It is impossible to anesthetize the Raschkow plexus with any type of anesthesia, so minor periodic pain sensations at the enamel-dentin border may occur in patients during tooth treatment with a bur, even with a fully anesthetized tooth.

Partly, it is the impossibility of affecting the Raschkow plexus that generates patients’ fears and numerous questions about whether it is painful to remove caries from teeth. However, there is no need to worry, as experienced doctors know how to minimize pain even in cases when the Raschkow plexus reacts.

How pain is minimized at our clinic:

• using the best anesthetics;
• using the sharpest burs;
• applying water irrigation to prevent tissue overheating.

Modern dentistry operates on the principle that the patient in the chair should not only be free from pain, but also feel comfortable. Overcoming patients’ fears of “white coats” is not easy, but one should understand: experienced specialists possess a large set of tools and deep knowledge. Even in complex clinical cases, our doctors will do everything possible to ensure the patient does not experience pain. On the other hand, patients themselves can protect themselves from unnecessary worries and stress: it is enough not to ignore routine check-ups and prevent the development of diseases. Treating caries at the first stage is simpler, faster, and cheaper.
