Toothache causing ear pain may be due to pericoronitis of the wisdom tooth. Conditions such as pericoronitis of the wisdom tooth often present with severe tooth pain. If left untreated, this may lead to referred pain—such as earache or pain during chewing. It is advisable to visit the Department of Stomatology at a reputable hospital, where treatment—such as wisdom tooth extraction—can be performed to prevent disease progression.
