Wisdom teeth are often referred to as third molars and, just like any other teeth, are susceptible to decay. It is a common dental issue that affects people of all ages globally, and The United States is no different in this regard. All types of teeth possess the top layer – enamel, dentin underneath, and pulp layers. Usually, when a person has a cavity, sharp shooting pains are the identifying marker that sends people to the dentist. However, a cavity might be making its way silently, too. If you see a black spot on your wisdom teeth without any pain, do not wait for it to go itself because the dot is most likely a painless cavity.

An Overview of Tooth Decay

Tooth decay is a common issue that hits both children and adults. You must have adequate knowledge to recognize the signs of its initiation to take preventive measures that would avoid pain and costly treatments. Decay begins with the formation of tiny holes that may be black or brown in color. This is caused by the penetration of bacteria and acid through the enamel. However, there are times when cavities ditch their original shape and form black lines on teeth, too.

Why Are Cavities Mostly Painful?

Pain and sensitivity are two common markers of cavities, but they may not be apparent until the decay progresses significantly into the deeper layers of your wisdom teeth. The second layer of dentin and all the surfaces from there house nerve endings and are sensitive to external factors. Once the hole is deep enough, stimuli trigger the nerves that send sharp shooting pain.

When Does A Wisdom Tooth Cavity Not Cause Pain?

An early-stage cavity starts in the enamel, which lacks sensitive nerves, making it immune to pain. It is when the bacteria goes deeper into the dentin layer that a sharp shooting sensitivity pain arises. Regular dental checkups are crucial for detecting these painless cavities and preventing further decay.

Other Signs of Cavity Growth

Why Wisdom Teeth Are Vulnerable to Cavities?

According to dental care experts, it is because of the following reasons:


Since wisdom teeth are the last set of molars to erupt, their position puts them at a disadvantage. Unfortunately, their location (back of the mouth) makes it challenging to access during regular cleaning that involves brushing and flossing. This creates an environment suitable for plaque buildup and, therefore, increases the risk of developing cavities.

Area Difficult to Reach

You have limited hand movement, and the size-to-mouth ratio makes flossing around wisdom teeth a very taxing task that is mostly achievable without external help. Inadequate oral hygiene for these teeth contributes to their increased susceptibility to cavities.

Diagnosis and Tests

Regular dental checkups scheduled twice a year play a pivotal role in diagnosing cavities early. Dental care specialists are equipped with state-of-the-art tools to not only thoroughly clean but also examine teeth. This checkup also includes probing for softness and may also use X-rays to identify cavities before they become visible.

Treatment Options We Offer for Cavities

You can trust oral health professionals to assess your condition and make the right call regarding treatment. Available options include:

Dental Fillings

We remove the decayed part of the teeth and clean the hollow. Once done, the hole in the wisdom tooth is filled with materials like composite resin, silver amalgam, or gold.

Root Canal Therapy

This procedure is performed by endodontists. They are specialized in removing the tooth pulp and filling the canals with a filler material. Once done, they may also place a dental crown to strengthen the tooth further.

Other Choices

Fluoride Flush

Consider it more like a preventive measure for protecting your teeth. Fluoride treatments can reverse a cavity in the enamel in the early stages. You can get prescribed toothpaste, mouthwash, and in-office fluoride treatments.

Tooth Extraction

When root canal therapy is not feasible, extraction may be recommended. Do not worry about your missing teeth since there are multiple replacement options, such as dental bridges or implants that can be discussed.

Preventing Wisdom Teeth Cavities

Prevention is better than cure, and these simple practices can make a significant difference:
