In addition, teeth can be discolored due to trauma or injury. This type of discoloration varies depending upon the kind of trauma experienced, the age of the tooth, and how quickly dental care is supplied. Types of Tooth Trauma Various types of trauma can occur to the teeth, both before and after they appear. In many cases, permanent teeth are injured and become discolored due to injury to the baby teeth. Trauma to teeth that have not yet fully developed occurs when the normal formation of enamel is disrupted, leading to opaque areas on the surface of the tooth. After a tooth has developed, damage to the pulp can cause discoloration due to bleeding within the tooth. If this damage is severe enough, the tooth might have suffered enough damage to the pulp to require a root canal. In some cases, orthodontic treatment can cause sufficient trauma to the tooth to result in minor discoloration, but this discoloration rarely results in extensive damage to the tooth’s pulp. Treating Tooth Trauma How well a tooth recovers from trauma depends largely on how promptly and efficiently it is treated. A tooth injury should be treated in a dental office as soon as possible, preferably within half an hour. This is especially important if the tooth has been knocked out. Tooth trauma is a common problem in dentistry, so a general or family dentist should be able to provide quick, efficient care.
