Dental---have 5 mm pockets. kept clean at home will never have gums reattach?

Deep Cleaning ?: You may require a deep cleaning, or 'scaling and root planing' of the affected areas, then a more thorough home-care regimen. Do the area(s) bleed? When? Have you been evaluated by your dentist, both radiographically and clinically? The short answer to your question is 'probably', but you may well not get any associated bone loss back. I hope that helps.

Stop the progression: Once the supporting bone around the teeth has been destroyed by periodontal disease it is almost impossible for it to grow back. What you can do, with your dentist and dental hygienists help is stop further progression of the disease. This entails learning how to properly reduce the bacterial biofilm daily, and stop further infection. Talk to your dentist and have him teach you the best ways.

S & RP by your Dr.: Only with the help of a dentist. The first place to start is a thorough examination, which should include a full series of x-rays. Periodontal charting is an invaluable tool. Scaling & root planing will remove toxins under your gums. There may also be other problems such as your bite. Part of the exam includes a treatment plan that details where you are today and what can be done for your future.
