![]() ![]() When probing the gum tissue, your dental professional will place a small measuring ruler called a periodontal probe in the space along the CEJ. ![]() To confirm this is the cause of your discomfort, a dental professional will measure the gum recession to determine the degree of CEJ exposure. This exposure is known as gum recession, the gum's process of coming away from the tooth's neck and shrinking down. Patients may feel sensitivity to hot and cold foods when the CEJ is exposed. Think of it as a tight turtleneck around the tooth's neck, keeping the less-mineralized root surface warm and protected from bacteria and acids. The CEJ acts as a covering of connective tissue. At this location, the hard, mineralized enamel stops, and the less-mineralized root covering begins. Still, in some people, this area contains a thin band of exposed dentin. ![]() In most cases, the cementum overlaps the enamel around the tooth. The cementoenamel junction is the specific line around the tooth's perimeter, where the enamel covering the crown of the tooth meets the cementum protecting the root. If you have pain in your tooth roots or notice an unexplained lump, see a dental professional to confirm. While cementoblastomas are rare, please do your best to rule out that you have them. While extracting a tooth is never ideal, the risk of the growth reappearing makes it essential. The best treatment includes the surgical removal of the cementoblastoma and the affected tooth, usually a lower premolar or molar. Treatment of a cementoblastoma involves removing the growth and the affected tooth or teeth. People in their teens through their late twenties hold a higher risk for cementoblastomas. Over time, they can interfere with the function of the teeth and can distort your facial appearance. Though cementoblastomas are benign, they never stop growing. This growth sometimes causes a dull pain, but it can often be asymptomatic. Still, it can occasionally spread to others and the surrounding bone. One tooth root usually contains all of the mineralized growth. It occurs when specific cementum cells grow at the tip of a tooth root. CementoblastomaĬementoblastoma is the long name for a specific rare growth on the root of a tooth. In addition to affecting tooth sensitivity and being affected by gum disease, cementum plays an essential role in a few oral health issues. The destruction of bones and cementum takes place in advanced gum disease and causes the loosening or shifting of teeth, and in some cases, tooth extraction may be necessary. This loss happens when the bones and fibers that hold the teeth in place are irreversibly damaged. Gum disease, or periodontitis, can cause cementum loss, for example. While cementum loss can cause issues, other issues like dental diseases can also contribute to cementum loss. If you know the feeling of wincing from taking a drink of cold water, you know the feeling of tooth sensitivity! You can recognize sensitivity in the form of a short or sharp pain in one or more teeth. As dentin becomes exposed, tooth sensitivity can occur. When cementum tooth loss occurs, the underneath dentin becomes exposed. These include sensitive teeth, enamel loss, and gum recession. What is Cementum's Role in Tooth Sensitivity and Gum Disease?Ĭementum loss contributes to a few common dental issues. Acellular cementum has only extrinsic fibers, covers the part of the tooth where the root meets the crown, and serves the purpose of anchoring the tooth in the gum. As noted in a 2016 study published in the Public Library of Science, cellular cementum is thick, contains collagen fibers (both extrinsic and intrinsic), and covers the bottom half of the root. What Are The Different Types of Cementum?Ĭementum has two main categories, cellular and acellular. Cementum also functions to cover the tooth's dentin, a bone-like substance that makes up most of our tooth structure. This connective tissue, called cementum, forms along a tooth's root and helps solidify it by connecting to fibers that support the tooth's place in the jawbone. ![]()
