Quick summary of this article+
Gingivitis is inflammation of the gums only — reversible, with bleeding and redness, treated with good hygiene and professional cleaning. Periodontitis is the advanced stage, where inflammation reaches the supporting bone, causing bone loss, recession and loose teeth; it can be controlled, but the bone damage doesn't fully recover. Recognizing it early (bleeding is the warning) prevents progression. In Mooca, Dr. Cléo Salustiano (CRO-SP 170844) sees patients every day, from 8 a.m. to 10 p.m.
Gingivitis or periodontitis: what's the difference? Put simply, gingivitis is inflammation of the gums only — milder and reversible; periodontitis is the more advanced stage, where inflammation reaches the bone that holds the teeth in place and causes damage that doesn't fully recover. One can turn into the other — which is why recognizing it early makes all the difference.
In clinical practice, many people treat the two as the same thing, but the distinction matters: gingivitis has a simple fix; periodontitis requires more careful treatment and ongoing follow-up. Knowing which stage you're in guides what to do.
Here, Dr. Cléo Salustiano (CRO-SP 170844) explains the difference between gingivitis and periodontitis, the signs of each, and how to treat and prevent them. Keep in mind that only an assessment, often with imaging, determines the stage and treatment for your case.

What's the difference between gingivitis and periodontitis?
Gingivitis is inflammation of the gums caused by plaque buildup. It makes the gums red, swollen and prone to bleeding, but it doesn't affect the bone yet — so it's reversible with proper hygiene and professional cleaning. It's the early stage and the best time to act.
Periodontitis happens when gingivitis goes untreated and the inflammation advances, reaching the tooth's supporting structures: the bone and the ligament. A 'periodontal pocket' forms, there is progressive bone loss and, over time, teeth can loosen and even fall out. It's more serious, and the bone damage doesn't fully recover.
The big difference, then, is depth: gingivitis stays in the gums; periodontitis reaches the bone. Gingivitis is reversible; periodontitis can be controlled, but it isn't 'reversible' in the sense of recovering all the lost bone — treatment stabilizes it and prevents progression.
The signs overlap at first (bleeding, redness), but periodontitis usually brings additional signs: persistent bad breath, receding gums, teeth that look 'longer' or feel loose, sensitivity and, sometimes, pus. The absence of pain is deceptive — the disease can progress silently.
Several factors raise the risk: insufficient hygiene, tartar, smoking, diabetes, hormonal changes, genetic predisposition and some medications. That's why control goes beyond brushing: it involves habits and overall health, assessed together.
Understanding this reinforces why you shouldn't ignore bleeding: it's the sign of gingivitis, the reversible stage. Treating it then prevents progression to periodontitis. The earlier, the simpler the treatment.
| Gingivitis | Periodontitis | |
|---|---|---|
| What it affects | The gums only | Gums, ligament and the bone that holds the tooth |
| Reversibility | Reversible | Controllable — bone already lost doesn't fully recover |
| Typical signs | Redness, swelling and bleeding; usually painless | Persistent bad breath, recession, teeth that look longer or feel loose, sometimes pus |
| Treatment | Professional cleaning and proper hygiene at home | Scaling below the gumline and, in some cases, additional procedures |
| After treatment | Regular checkups and cleanings | Ongoing periodontal maintenance |
| Risk of not treating | Progressing to periodontitis | Loose teeth and tooth loss |
How to treat and prevent each one
Gingivitis is usually treated by removing plaque and tartar (professional cleaning) combined with good hygiene at home. In general, the gums return to health quickly. It's the ideal scenario: simple, reversible treatment when you act early.
Periodontitis requires more in-depth treatment, such as scaling and root planing (removing tartar below the gumline) and, in some cases, additional procedures. The goal is to control the inflammation, stabilize bone loss and stop progression. It isn't a cure in the sense of recovering everything, but control — and it works well when properly managed.
In both cases, maintenance is decisive: regular cleanings and thorough hygiene at home. With periodontitis especially, ongoing follow-up (known as periodontal maintenance) is what keeps the disease under control over time.
Home hygiene is the foundation: gentle brushing along the gumline, plus floss or an interdental brush every day. Most of the plaque that causes these diseases builds up precisely between the teeth and along the gumline, where only floss and proper technique can reach.
Managing risk factors strengthens the treatment: quitting smoking, controlling diabetes and reviewing medications with your physician, when relevant. These factors influence both the onset of gum disease and how it responds to treatment.
Finally, prevention is always the way to go: daily hygiene plus regular checkups and cleanings keeps gingivitis from appearing or progressing. Healthy gums are also a prerequisite for cosmetic treatments. Caring for them is investing in your whole smile.

What's the difference between gingivitis and periodontitis?
+
Gingivitis is inflammation of the gums only, milder and reversible. Periodontitis is the advanced stage, where inflammation reaches the bone that holds the teeth, causing bone loss. In short: gingivitis stays in the gums; periodontitis reaches the bone.
Can gingivitis be cured?
+
Yes. Gingivitis is reversible: with plaque and tartar removal and good hygiene, the gums return to health. It's the ideal stage to treat, precisely because there's no damage to the bone yet. That's why you shouldn't ignore bleeding, which is its sign.
Can periodontitis be cured?
+
Periodontitis can be controlled, but it isn't 'reversible' in the sense of recovering all the bone already lost. Treatment stabilizes the disease, controls inflammation and stops progression. With ongoing follow-up, it's possible to keep teeth healthy for many years.
Does gingivitis always turn into periodontitis?
+
Not necessarily, but it can if left untreated. Periodontitis starts as gingivitis that progressed. That's why treating gingivitis early is the best way to prevent periodontitis. Not all gingivitis progresses, but there's no way to know without taking care of it.
What are the signs of gingivitis?
+
Red, swollen gums that bleed when you brush or floss. It usually doesn't hurt, which is why many people ignore it. These signs point to early inflammation — the ideal time to treat, before it progresses to periodontitis.
What are the signs of periodontitis?
+
Besides bleeding, there's often persistent bad breath, receding gums, teeth that look 'longer' or feel loose, sensitivity and, sometimes, pus. It can progress without pain, silently. These signs call for a prompt assessment.
Can periodontitis cause tooth loss?
+
Yes. Because it affects the bone that holds the teeth, advanced periodontitis can lead to loose teeth and tooth loss. It's one of the main causes of tooth loss in adults. Treatment and maintenance are what prevent that outcome.
How is periodontitis treated?
+
It usually involves scaling and root planing (removing tartar below the gumline) and, in some cases, additional procedures, plus regular maintenance. The goal is to control inflammation and stabilize bone loss. Ongoing follow-up is an essential part of treatment.
Can you have periodontitis without pain?
+
Yes, and that's the trickiest part. Periodontitis tends to progress silently, without pain, until it reaches more serious stages. That's why you shouldn't wait for it to 'hurt' before getting checked — bleeding and bad breath are already warning signs.
What causes these gum diseases?
+
The root cause is plaque and tartar buildup from insufficient hygiene. Factors such as smoking, diabetes, hormonal changes, genetics and some medications raise the risk and severity. That's why control involves both hygiene and overall health.
How can I prevent gingivitis and periodontitis?
+
With daily hygiene (gentle brushing along the gumline plus floss or an interdental brush) and regular professional checkups and cleanings. Managing factors such as smoking and diabetes also helps a lot. Prevention is always simpler than treatment.
Are smokers at higher risk?
+
Yes. Smoking raises the risk and severity of periodontal disease and also masks bleeding, delaying diagnosis. It impairs healing and the response to treatment, too. Quitting is one of the biggest benefits you can give your gums.
Is periodontitis linked to overall health?
+
Studies associate periodontal disease with conditions such as diabetes and cardiovascular problems, in a two-way relationship. Caring for your gums is part of caring for your health as a whole. That's why control often involves medical follow-up as well.
Do unhealthy gums rule out whitening or veneers?
+
Yes, aesthetics start with health. Active gingivitis or periodontitis needs to be treated before whitening, veneers or implants, because it compromises the outcome and safety. Treating the gums is the first step toward a beautiful smile.
