👉 In dentistry, a subglabrous tooth is a type of dental tooth that does not have any sharp or prominent ridge on its surface. This condition can be caused by various factors such as periodontal disease, trauma to the tooth, and gum disease. Subglabrous teeth are often described as having a white or yellowish color, which may make them difficult to visually differentiate from normal teeth. They can also be more prone to tooth decay and sensitivity.
