Three Main Reasons for Wisdom Teeth Extraction

Key Point: Wisdom teeth are the third molars that emerge after the age of 16 or have yet to emerge. Due to the reduction in jaw size during human evolution, there is often insufficient space in the jaw to accommodate wisdom teeth, causing them to emerge in abnormal positions and directions. Wisdom teeth not only have no chewing function, but also pose a series of risks or potential hazards, making early extraction the best option.

1. Due to incomplete eruption, the gum covering the posterior aspect of the tooth crown forms a periodontal pocket, which can accumulate food and bacteria and cause frequent local soft tissue inflammation, unbearable pain, and even limited mouth opening and difficulty in eating. Some people are unwilling to have them removed after the inflammation subsides and they no longer experience pain or difficulty eating, but the symptoms can worsen if the condition recurs.

2. Most wisdom teeth are inclined forward and obstructed, with the crown at a 45-degree angle on top of the second molar, forming a corner that traps food. Over time, the second molar can become decayed and develop pulpitis, causing severe pain. Another consequence is that the forward-leaning wisdom tooth continues to exert pressure on the second molar, causing periodontitis and loosening of the tooth, necessitating the removal of the second molar, or even both, severely impairing chewing function.

3. Although some wisdom teeth emerge in roughly the correct direction, they may have abnormal contact points with the second molar, trapping food and being difficult to reach when brushing, causing the second molar to decay and shortening its lifespan.

Many people now believe that as long as their teeth are not causing pain, there is no need for treatment or extraction, but this is incorrect. If the tooth is already causing pain, irreversible damage may have already been done to the tooth or even the body, and it may be difficult to recover the loss caused by the wisdom tooth.

According to statistics, 50% of people have wisdom teeth, which usually emerge around the age of 16. Since the root of the tooth is not fully formed when it first emerges, it is easier to extract at this time, and removing it can prevent damage to the second molar and the body. Therefore, early extraction is the best treatment option. As the saying goes, "prevention is better than cure".

Although many people are aware of the dangers of wisdom teeth and the need for extraction, they are hesitant to seek treatment because of the fear of pain. In fact, with local anesthesia, the extraction is virtually painless, as many who have had their teeth extracted can attest. Therefore, worrying about pain is unnecessary, and failure to extract the tooth may result in recurring pain.
