Wisdom teeth erupt late and generally do not erupt until adulthood. If there are no missing or decayed molars in front of the wisdom tooth, it is usually not necessary to keep it. The process of wisdom tooth eruption can produce pericoronitis and recurrent swelling and pain. Long-term pericoronitis of the wisdom tooth can lead to periodontitis of the anterior teeth, periapical inflammation of the anterior teeth, etc. In severe cases, the anterior teeth may loosen and fall out. Obstructed wisdom teeth can lead to decay of anterior teeth, which can lead to loss of anterior teeth in serious cases. Some of the wisdom teeth cannot erupt and form cysts, which need surgical treatment and seriously affect the solidity of the front teeth and jawbone. Low level obstructed wisdom teeth can lead to root resorption of anterior teeth and in severe cases lead to loss of anterior teeth. The chances of these complications occurring individually or in combination are quite high, and most people will visit the clinic for one or more of these complications, at which point the wisdom teeth will also need to be extracted. Treatment at this point is equivalent to mending the problem, and it is better to remove it as early as possible rather than doing so. It is advisable to remove the unerupted wisdom teeth by the second year of high school at the latest.
