Gum disease is the condition most people have some degree of and almost nobody notices, because it does not hurt until it is advanced. Knowing the stages tells you what is still reversible. Gum disease moves from gingivitis, where the gums are red and bleed but the bone is intact, to periodontitis, where the attachment and bone start to break down, and the first stage is reversible with cleaning and better home care while damage from the later stages can only be controlled, not undone.
Why it is so often missed
Gum disease is usually painless until it is advanced. There is no toothache to prompt a visit, and the earliest sign, bleeding when brushing, is widely assumed to be normal or to mean you are brushing too hard.
Bleeding gums are common. Common is not the same as normal, and it is the signal worth acting on.
The stages
Diagnosis comes from pocket measurements around each tooth and X-rays showing the bone level, not from appearance alone.
| Stage | What is happening | Reversible? | Typical treatment |
|---|---|---|---|
| Healthy | Firm, pale pink gums; no bleeding | — | Routine cleaning and maintenance |
| Gingivitis | Inflammation of the gum only; bleeding on brushing | Largely yes | Improved daily cleaning and a professional clean |
| Early periodontitis | Inflammation reaching bone; deeper pockets forming | Progression can be halted; lost bone does not return | Deep cleaning (scaling and root planing) |
| Moderate periodontitis | More bone lost; pockets deeper; possible recession | No: but it can be stabilized | Deep cleaning, shorter recall, sometimes referral |
| Advanced periodontitis | Significant bone loss; teeth may loosen or drift | No | Specialist care; some teeth may not be savable |
What actually changes the outcome
Gum treatment succeeds or fails on what happens between appointments more than on the appointments themselves.
- Daily cleaning between the teeth, in whatever form you will genuinely do
- Stopping smoking: it materially worsens outcomes and masks bleeding
- Managing diabetes, which has a two-way relationship with gum health
- Attending the shorter recall interval you are given after treatment
- Reporting returning bleeding rather than waiting for the next visit
Common questions
The Stages of Gum Disease: questions people ask
Can gum disease be cured?
Gingivitis can largely be reversed. Periodontitis can be stabilized and its progression stopped, but bone that has already been lost does not grow back on its own.
Why do I need cleanings every three or four months?
Because a history of periodontitis changes the risk. Shorter intervals after treatment are about protecting a result you have already paid for.
Can I lose teeth from this?
Yes. Gum disease is a leading cause of adult tooth loss, and it usually does so without pain. That is exactly why the painless early signs matter.
Is bleeding when I floss a reason to stop flossing?
No: it is usually a reason to keep going. Gums that bleed are inflamed, and consistent cleaning commonly settles it within a couple of weeks. If it persists, get it assessed.
How is gum disease diagnosed?
By pocket measurements around each tooth and X-rays showing the bone level, not by appearance alone. Gum disease is usually painless until it is advanced. The earliest sign is bleeding when brushing. Bleeding gums are common, but common is not the same as normal.
What is reversible at each stage of gum disease?
Gingivitis, inflammation of the gum only, is largely reversible. In early periodontitis progression can be halted, but lost bone does not return. Moderate periodontitis cannot be reversed but can be stabilized. Advanced periodontitis has significant bone loss, and some teeth may not be savable.
