Periodontal disease is a progressive and chronic disease. In other words, once you have periodontal disease, with the exception of gingivitis, you always have it. It can, however, be halted and in some cases partially reversed. The most common periodontal condition is gingivitis, however, when bacteria begin to infect and thus affect the bones around your teeth instead of just the gums, full periodontal disease results. Most minor periodontal disease can be addressed in a general dentist office through scaling and root planing. More advanced cases of periodontal disease may require a specialist.
