Can periodontal gaps return to normal after treatment for periodontitis?

When periodontitis is mild and there is no significant alveolar bone loss, the gaps between teeth may close after treatment. However, if the condition is severe with extensive alveolar bone absorption, the gaps usually cannot be fully restored; treatment can only prevent them from getting larger. If you notice redness, swelling, or bleeding of the gums, seek timely medical evaluation and follow-up.

In the early stage of mild periodontitis, although the gums may appear red, swollen, and bleed easily, alveolar bone loss is minimal and gum tissue has not significantly receded. After professional periodontal cleaning and scaling to remove plaque and tartar, inflammation gradually subsides. The gums can reattach to the tooth root surface, causing the gaps that were widened due to inflammatory swelling to shrink or even disappear completely. This recovery process typically takes 1–2 months.

If periodontitis progresses to a moderate or severe stage, prolonged inflammation leads to substantial alveolar bone loss. The gums lose underlying bone support and recede noticeably, exposing the roots and creating permanent gaps between teeth—these are structural defects. Even with successful treatment to control infection, the lost alveolar bone rarely regenerates, and the gums cannot regain their original height. As a result, the gaps remain. In such cases, the primary goal of treatment is to prevent further widening of the gaps and halt disease progression.

For daily care, consistently brush your teeth twice daily using a soft-bristled toothbrush and the Bass brushing technique. Clean between teeth with dental floss or a water flosser after meals. Have a periodontal examination and professional cleaning every six months to one year. Avoid biting down on excessively hard objects to minimize damage to periodontal tissues.
