Final answer:
True, an inadequate contour of a tooth can damage the gingiva, leading to conditions such as gingivitis and periodontitis, which may result in tooth loss and the erosion of the jawbone if untreated.
Step-by-step explanation:
True, if a tooth has an inadequate contour, the gingiva may be damaged. The tooth is comprised of two main parts: the crown above the gum line, and the root within the jawbone. An incorrect contour of the tooth can interfere with the natural cleaning processes of chewing and saliva flow, potentially leading to the buildup of dental plaque and the subsequent inflammation of the surrounding gingival tissues, a condition known as gingivitis.
Gingivitis is the initial stage of periodontal disease, which can progress to periodontitis if left untreated. With periodontitis, the gums recede and expose parts of the tooth normally covered, allowing bacteria to grow and spread, leading to further complications like tooth loss and jawbone erosion. Proper oral hygiene and dental care are essential to prevent and treat these conditions.
