Ask your dentist if a simple, often nearly painless procedure should be performed which involves removal and re-contouring of small amounts of gum (a ‘gingivectomy' or a ‘papillectomy'). This will open up the plaque trap and enable you to get an interdental brush into the area which was previously impossible to clean. Use the biggest one you can comfortably get into the gap. You will be amazed by the improvement in the condition of your gums that will follow. Sometimes the disease process has gone to the point where the bone has changed into a shape that is not in your best interests. You need to get your bone reshaped to create self cleansing, not self-contaminating and self destroying contours. Food and plaque should be easily removed from between your teeth, not caught in traps created by the disease process. Although this sounds painful, it is not really that bad and the benefits far outweigh the temporary discomfort. It may actually save your teeth or at least extend their useful life. Talk to your hygienist, dentist or periodontist about the benefits of gingival and osseous restoration and periodontal pocket reduction surgery.
