After you finish your rounds of scaling and root planing, the dentist/hygienist will recommend a maintenance intervals (supportive periodontal treatment or "perio maintenance visits") They are similar to the patient as a "regular cleaning" but since you have some areas of gums disease these areas are monitored and retreated if necessary by the dentist or hygienist so they are very different. It varies by individual but most commonly you see 3, 4 or 6 month intervals. Research has found that it takes about 9-11 weeks for bacteria to get back down under the gums after therapy so the closer you are to that time frame the better the prognosis is for diseased sites. Most insurances will only pay for 2 "cleanings" a year so the rest is out of pocket. That is where you see patient compliance waver.
The disease can get better but does not entirely go away since once you have bone loss you have it for life (unless you have surgury). So the goal of scaling and root planing/perio maintenance (non-surgical periodontal treatment) is to maintain the disease so you do not loose anymore bone. Even though you have lost bone the periodontal probing numbers can improve (going from 6mm to 4mm) with no bleeding. This will make it easier for you to keep clean at home on a continuous basis and easier for the dental team to treat.
Sounds like you are doing everything right, that is awesome. It is hard work but its worth it
