Dental infections are characterized by intense pain, persistent and sharp, manifest dental abscesses (pus inflammation and accumulation) in the area where the tooth, therefore, can be presented to dental or gingival level. Infections are usually due to a bacterial problem and using natural antibiotics to ward off any dental infection is one of the best courses of action, and some of the causes can be:

  2. Periodontal disease: When gingivitis is not treated in time, it can transform into periodontitis, and if it is allowed to advance, it can reach the jaw bone.
  3. Trauma: When a tooth is broken or chipped from a blow, it also becomes vulnerable to bacteria. It can also be caused by a crack or hole in the tooth.
  4. Sharp object injury: When we introduce foreign objects into the mouth (toothpicks, pens, etc.), this can injure the gums, and if good hygiene habits are not in place, the wound could be exposed to bacteria inside the oral cavity.
