Wisdom teeth are normal teeth that erupt in our physiology and are very normal and do not imply disease. Wisdom teeth, also known as 3rd molars, are normal teeth that begin to erupt after the age of 18, and their eruption coincides with the period of maturity of the human mind, which is why they are also known as wisdom teeth. If the wisdom teeth are normally grown, in a normal position, have a good bite and are performing chewing functions, they are our normal teeth and there is no need for any treatment. However, in the case of wisdom teeth, since people are chewing more and more fine foods nowadays, many wisdom teeth have insufficient space in the jawbone when they erupt. The ectopic erupted wisdom tooth will form a gap around it and retain bacteria, which will cause peri-coronitis of the wisdom tooth and cause repeated pain to the patient, and at the same time, the forward growing wisdom tooth will sometimes lead to decay or even loss of the second molar in front. Therefore, for the abnormal eruption of wisdom teeth, we need to remove them.
