White bumps on the gums of adults may be chronic apical periodontitis, alveolar bone hyperplasia, jawbone tumors, etc., and should be promptly consulted to find out the cause of the disease. 1. Chronic periapical inflammation: If the patient has chronic periapical inflammation, there will be white bumps on the gums, pustules will be formed locally, there is no breakthrough, it is not painful, it is softer when pressed with a finger, and there are carious cavities in the teeth on the local edge, and the pulpal nerves may have been necrotic, so it is necessary to do root canal treatment. 2. Alveolar bone hyperplasia: If the white bump on the gums is hard to touch, it is considered to be alveolar bone hyperplasia, which usually occurs at the turning point of the dental arch, because the teeth in this position are subjected to more force, and the limited hyperplasia will cause white granular bumps. 3. Jawbone tumor: it is a tumor that occurs in the maxilla, mandible and adjacent tissues, which can be manifested as white bumps on the gums, which will gradually increase in size.
