K03.5: Ankylosis of teeth
One or more of your teeth have fused with your jaw bone.
The tooth is anchored firmly in the jawbone by the periodontal ligament. This ligament includes, among other things, the outermost layer of the tooth root and the gums. The periodontal ligament also includes the hole in the jawbone in which the tooth is located. Small fibers anchor the root of the tooth in its hole in the jaw bone.
If these fibers turn into bone-like tissue, the tooth and the bone can fuse. This can happen both with milk teeth and adult teeth. A tooth that is affected may be unable to break through the gum as it usually would. A tooth that is affected may also be unable to fully grow out of the jaw bone. The tooth may then look smaller than the surrounding teeth. It may then be more difficult than usual to extract an affected tooth.
There are different reasons for fused teeth. One possible cause may be changes in the genetic information. Injuries or inflammations may cause the fusion.
