Gum disease is one of the most common chronic conditions in adults, and it often causes no pain until it is advanced. According to the CDC, about 4 in 10 U.S. adults aged 30 or older had some level of periodontitis in 2009–2014, rising to about 60% of adults aged 65 or older. The good news is that the early stage, gingivitis, is reversible, and daily habits make a real difference.
Gingivitis vs periodontitis
| Gingivitis | Periodontitis | |
|---|---|---|
| What it is | Inflammation of the gums caused by plaque | Infection and inflammation that damage the tissues and bone supporting the teeth |
| Typical signs | Red, swollen gums that bleed when brushing | Gum recession, pockets, loose teeth, pain when chewing, persistent bad breath |
| Reversible? | Yes, with good hygiene and professional cleaning | Damage can be controlled but not fully reversed |
| Treatment | Better brushing, cleaning between teeth, professional cleaning | Deep cleaning (scaling and root planing), sometimes surgery, then ongoing maintenance |
Warning signs to watch for
- Red, swollen or tender gums
- Bleeding when you brush or floss
- Gums pulling away from the teeth
- Persistent bad breath or a bad taste (see bad breath causes)
- Loose teeth or a change in your bite
- Pain when chewing
Who is at higher risk?
The CDC lists these risk factors:
| Risk factor | Why it matters |
|---|---|
| Smoking | 62% of current smokers aged 30 and older had periodontitis (CDC). Smoking is one of the strongest risk factors. |
| Diabetes | Associated with higher risk and severity of gum disease |
| Poor oral hygiene | Plaque that isn’t removed hardens and inflames the gums |
| Genetics | Some people are more susceptible |
| Stress and hormonal changes | Can affect the body’s inflammatory response |
| Medications | Some reduce saliva or affect the gums |
| Obesity or poor nutrition | Linked to higher risk |
| Crooked teeth or grinding | Harder to clean, extra force on supporting tissues |
How to prevent gum disease
- Brush twice a day with fluoride toothpaste, angling the brush towards the gumline.
- Clean between your teeth every day. A Cochrane review found low-certainty evidence that adding floss or interdental brushes to toothbrushing may reduce gingivitis more than brushing alone. Interdental brushes are often easier where the gaps are large enough.
- Get regular professional cleanings and a dental check-up at least once a year, as the CDC recommends. Your dentist may suggest more frequent visits.
- Don’t smoke, and get support to quit if you do.
- Manage diabetes and other health conditions.
Can supplements prevent gum disease?
No supplement replaces the basics above. Probiotics have the most research: a 2025 meta-analysis found benefits for plaque and bleeding when they were added to professional treatment for periodontitis, but not significant results in gingivitis. See oral probiotics: what the research shows and our ProDentim review. Xylitol gum may help as an adjunct for plaque. See xylitol for teeth.
When to see a dentist
Book an appointment if your gums bleed regularly, look swollen or receding, or you notice loose teeth or persistent bad breath. Early treatment is simpler and more effective.
FAQ
Is it normal for gums to bleed when flossing?
Bleeding is a sign of inflammation. It often improves within a couple of weeks of consistent cleaning. If it doesn’t, see a dentist.
Can gum disease affect overall health?
Gum disease is associated with conditions such as diabetes. Treating gum disease and managing general health both matter.
