Gum disease is one of the most common conditions we see — and one of the most misunderstood. Nearly half of adults over 30 have some form of it, yet many don’t realize how treatable it is when caught early.
Gingivitis vs. Periodontitis: What’s the Difference?
Gingivitis is the earliest stage of gum disease. Plaque buildup along the gumline irritates the tissue, causing redness, swelling, and bleeding when you brush or floss. At this stage, no permanent damage has occurred to the bone or ligaments holding your teeth in place — which means gingivitis is fully reversible with improved oral hygiene and a professional cleaning.
Periodontitis develops when gingivitis goes untreated. The infection spreads below the gumline, breaking down the bone and connective tissue that anchor your teeth. Unlike gingivitis, the damage from periodontitis cannot be fully reversed — but it can be stopped and managed with the right treatment.
The Stages of Periodontitis
- Stage 1 (Early): Minor bone loss, pockets forming between teeth and gums (4mm or less)
- Stage 2 (Moderate): Increased pocket depth (5-6mm), noticeable bone loss on X-rays
- Stage 3 (Severe): Significant bone loss, deeper pockets, possible tooth mobility
- Stage 4 (Advanced): Extensive bone and tissue loss, risk of tooth loss, possible bite changes
How Each Stage Is Treated
- Gingivitis: A professional cleaning plus a consistent brushing and flossing routine at home is usually enough to reverse it completely.
- Early-to-moderate periodontitis: Scaling and root planing — a deep cleaning that removes plaque and tartar from below the gumline and smooths root surfaces — is the standard treatment, sometimes paired with localized antibiotics.
- Severe-to-advanced periodontitis: May require more advanced procedures like flap surgery, bone grafting, or guided tissue regeneration, along with more frequent maintenance cleanings.
The Takeaway
The earlier gum disease is caught, the simpler — and less expensive — it is to treat. Bleeding gums are never “normal,” even if it’s just a little blood when you floss. If you notice persistent redness, swelling, bleeding, or bad breath that won’t go away, it’s worth having your gums evaluated before gingivitis has a chance to progress.
