牙龈长包挂What科
Generally, when a bump appears on the gums, patients can choose to visit departments such as Conservative Dentistry and Endodontics, Periodontology, Oral and Maxillofacial Surgery, Oral Mucosal Diseases, or Pediatric Dentistry depending on specific symptoms. Detailed analysis is as follows:
1. Conservative Dentistry and Endodontics
Bumps on the gums are often caused by periapical periodontitis, in which case patients should visit the Department of Conservative Dentistry and Endodontics. Untreated dental caries may lead to pulp infection, with inflammation spreading to the periapical tissues and forming an abscess. Doctors in this department use X-ray imaging to determine the extent of infection and perform root canal treatment to remove infected pulp, eliminate inflammation, and resolve the bump.
2. Periodontology
If the bump is accompanied by redness, swelling, bleeding of the gums, or formation of periodontal pockets, it may be a periodontal abscess, requiring consultation with the Department of Periodontology. This condition is usually caused by long-term irritation from dental plaque and calculus. Doctors will perform incision and drainage to expel pus, followed by periodontal cleaning to remove irritants and control the progression of inflammation.

3. Oral and Maxillofacial Surgery
When the bump results from organic lesions such as jaw cysts or tumors of the oral and maxillofacial region, or if minor surgical procedures like incision and drainage are required, patients should visit the Department of Oral and Maxillofacial Surgery. This department specializes in surgical conditions of the oral and maxillofacial area and resolves underlying issues through surgical removal of diseased tissue or abscess drainage.
4. Oral Mucosal Diseases
If the bump is not caused by dental or periodontal problems but rather by mucosal lesions such as oral mucosal inflammation or mucoceles (mucous gland cysts), patients should consult the Department of Oral Mucosal Diseases. Doctors will conduct mucosal examinations to identify the cause and use medication or other treatments to relieve mucosal inflammation and eliminate the bump.
5. Pediatric Dentistry
When children develop gum bumps, they should first visit the Department of Pediatric Dentistry. Due to the unique developmental characteristics of primary and permanent teeth in children, doctors in this department are familiar with pediatric oral anatomy and can provide age-appropriate diagnosis and treatment for common issues like pulpitis or periapical inflammation in primary teeth, ensuring both effective treatment and proper tooth development.
In addition, if unsure about which department to visit, patients can seek assistance from the hospital’s guidance desk. Maintaining good daily habits such as brushing teeth twice a day, rinsing after meals, and undergoing regular dental check-ups can effectively prevent oral problems including gum bumps.
