Gingivitis versus periodontitis
Gingivitis is inflammation limited to the gum tissue. Gums look red or swollen and bleed when brushed, but the bone holding the teeth is intact. It is fully reversible with thorough cleaning and better home care.
Periodontitis begins when that inflammation extends below the gumline and the body starts resorbing the bone around the root. Pockets deepen, the seal around the tooth fails, and the loss is permanent. Roughly forty percent of American adults over thirty have some degree of it.
The signs worth acting on
Bleeding when you brush or floss is the earliest and most ignored sign. Healthy gums do not bleed. Others include persistent bad breath, gums receding so teeth look longer, dark triangles opening between teeth, tenderness when chewing, a metallic taste, and teeth that feel slightly mobile or have shifted position.
Because the process rarely hurts, most people notice only when a tooth loosens — which is late in the sequence.
Why it matters beyond your mouth
Chronic periodontal inflammation is associated with cardiovascular disease, poorly controlled blood sugar in diabetes, respiratory infection, and adverse pregnancy outcomes. The relationship runs in both directions: diabetes worsens gum disease, and gum disease makes blood sugar harder to control.
Treating gum inflammation is one of the few dental interventions with measurable whole-body benefit.
What treatment involves
Gingivitis usually resolves with a thorough cleaning plus a corrected home routine focused on the gumline and between teeth. Established periodontitis is treated with scaling and root planing, a deep cleaning of the root surfaces performed with local anesthesia, often quadrant by quadrant.
Afterward, maintenance visits every three to four months keep bacteria below the threshold that restarts bone loss. Surgical or regenerative options exist for advanced pockets. The earlier you start, the less of this is necessary.
