Periodontitis can certainly be treated with teeth cleaning. Periodontitis develops further from gingivitis, which occurs when food residues accumulate around the gums due to not brushing and rinsing promptly after eating. This long-term irritation causes the gum tissue to become congested, swollen, or even suppurative. As gingivitis progresses, it can lead to periodontitis, an inflammation of the tissues surrounding and supporting the teeth. If periodontitis is not treated promptly by cleaning the teeth and removing local irritants, it can eventually cause the teeth to become loose and, in severe cases, lead to tooth loss. It is advisable to seek early treatment from a periodontal specialist for periodontitis.
