If the wisdom tooth becomes impacted against another tooth, food debris and bacteria can become lodged between the teeth and give rise to tooth decay. If the decay progresses, it can spread into the pulp of the adjacent tooth, resulting in severe pain. In such a situation, the adjacent tooth may need root canal treatment to treat the infected dental pulp. How quickly the decay progresses depends on one’s diet, saliva flow, eating and brushing habits, etc. Timely removal of impacted wisdom teeth in these situations can help you avoid costly consequences.
