The pain arising at the root of the tooth’s nerve causes toothache or irritates the neighbouring tooth. There could be several reasons for the toothache like, dental cavity, crack in tooth, abscess, exposed nerve or root. Sometimes, it can be even caused by the food getting stuck in the gums or due to a bacterial infection. Even gum disease can be a reason for the toothache. Severe toothaches require treatment by a dental professional from Blacktown dental clinic to find the cause and resolve the pain. Call 02 9621 5566 to fix an appointment with the dentist today!
