Many impacted wisdom teeth cause no pain, swelling, or obvious symptoms. However, that does not always mean they are harmless.

A 2024 study published in The Saudi Dental Journal found that impacted lower wisdom teeth were frequently associated with tooth decay, particularly on the back surface of the neighboring second molar. In many cases, the healthy tooth next to the wisdom tooth was affected more often than the wisdom tooth itself.

Researchers analyzed 1,591 dental panoramic X-rays and found that nearly 40% of impacted lower wisdom teeth were associated with carious lesions. The highest risk was seen when the wisdom tooth was tilted forward toward the adjacent tooth (mesioangular impaction), creating an area where plaque, bacteria, and food debris can accumulate and become difficult to clean.

This is one reason dentists often recommend regular monitoring of impacted wisdom teeth. Hidden decay can develop between teeth long before pain appears, and by the time symptoms occur, significant damage may already have occurred.

Regular dental examinations and panoramic X-rays can help detect these problems early and protect the healthy tooth next to an impacted wisdom tooth.
