The wisdom tooth is wrapped in flesh and does not necessarily have to be extracted. The location and direction of the wisdom tooth and whether it is extruding the neighboring teeth should be examined in conjunction with the full-mouth surface tomography, and the doctor will determine whether it needs to be extracted according to the specific situation. If the wisdom tooth is completely encapsulated and does not squeeze the neighboring teeth, it can be retained and observed regularly. If the wisdom tooth grows partially in a vertical direction and there is no swelling or pain, the encircled tooth can be allowed to grow by removing part of the gum above it. However, if the examination results show that the wisdom tooth grows in a crooked direction and affects the growth of the neighboring teeth, such wisdom teeth should be extracted as soon as possible. The wisdom teeth that cannot be fully erupted are called blocked wisdom teeth. The deep blind pocket between the crown and gum of blocked wisdom teeth is easy to accumulate food residues, which can cause bacteria growth and diseases such as pericoronitis and decay of neighboring teeth, and may also cause facial swelling and infection, etc. In this case, local flushing and anti-inflammatory medicine should be applied, and if necessary, extraction of blocked wisdom teeth should be performed. It is recommended to pay attention to oral hygiene everyday, brush your teeth thoroughly to prevent food residue, you can apply electric toothbrush and flosser to help clean your teeth properly. Do not eat too much sweet food or drink drinks with high sugar content to prevent corrosion of teeth. Check your teeth regularly and treat any abnormalities as soon as possible.
