Wisdom teeth, which are actually your third molars, are the last teeth to emerge and are the farthest back in your mouth. Wisdom teeth are named for thought that a person reaches maturity between the ages of 17-25, which is when they usually erupt.
Wisdom teeth are removed for a number of reasons. These teeth often grow sideways in the bone, also known as impacted, causing pain, discomfort, and sometimes infection. Wisdom teeth are also very large and if left alone can cause misalignment of the other teeth. This is especially detrimental to a patient in orthodontics or who has previously had orthodontics as teeth can shift as wisdom teeth move or erupt. Wisdom teeth are also difficult to clean thoroughly even if there is enough room for them to full erupt. For this reason they are extracted to reduce the chance of complication in the future.
Wisdom teeth are usually removed by an oral surgeon who specializes in removing wisdom teeth. They can remove wisdom teeth with IV sedation that ensures the patient is comfortable for the entire process.
