In cases of advanced gum disease and tooth decay, teeth may need to be extracted. Some patients may also develop impacted wisdom teeth, which can cause intense pain. This is alleviated by having them removed surgically. One area in which it is possible for dentists to specialise is oral surgery, an umbrella term for all dental procedures involving surgery, such as the extraction of teeth or wisdom teeth. It is always important to get the advice of a dental professional if you are worried about any of your teeth. Never attempt to pull out your own tooth at home as this could cause a more serious problem for you.
