Periodontal disease is an infection of the gums and the bone that support your teeth. It starts when bacterial plaque builds up along and below the gumline, triggering inflammation that can range from mild gum irritation to serious bone damage. Nearly half of all adults over 30 in the United States have some form of it, according to the CDC.
The difficult part is that gum disease doesn’t always hurt, especially early on. Many people have no idea anything is wrong until their dentist finds deeper gum pockets during a routine exam. That’s why understanding what causes it, how to spot the warning signs, and what treatment looks like can make a real difference in protecting your teeth long term.
Key Takeaways
- Periodontal disease is a bacterial infection that damages the gums and bone supporting your teeth, affecting nearly half of U.S. adults over 30.
- Gingivitis is the earliest stage and is fully reversible with professional cleaning and better home care.
- Once the disease progresses to periodontitis and bone loss occurs, the damage can be managed but not fully reversed.
- Risk factors include smoking, diabetes, certain medications, hormonal changes, and genetics.
What Causes Periodontal Disease?
Bacterial plaque is the primary cause. When plaque isn’t removed through daily brushing and flossing, it hardens into tartar that can only be removed by a dental professional. The bacteria in plaque and tartar produce toxins that irritate gum tissue and, over time, break down the bone that holds your teeth in place.
Several factors raise your risk. Smoking is one of the biggest. Smokers are far more likely to develop gum disease, and smoking makes treatment less effective. Diabetes is another major factor. It reduces the body’s ability to fight infection, including infections in the gums.
Other risk factors include certain medications that reduce saliva flow or cause gum tissue overgrowth, hormonal changes during pregnancy or menopause, a family history of gum disease, and poor nutrition. Some people are genetically more prone and may need more frequent cleanings to keep the condition under control.
Gingivitis vs. Periodontitis
These are the two main stages of gum disease, and the difference between them matters because it determines whether the damage can be fully undone.
Gingivitis is the early stage. Gums become red, swollen, and may bleed when you brush or floss. There’s no bone loss yet. The good news: gingivitis is completely reversible with a professional cleaning and consistent home care. It’s a warning, not a permanent diagnosis.
Periodontitis develops when gingivitis goes untreated. Bacteria spread below the gumline. The gums pull away from the teeth, creating pockets that trap more bacteria. The body’s immune response starts breaking down bone and connective tissue. This is what causes teeth to loosen over time. Periodontitis ranges from mild to severe, and in advanced cases, teeth may need to be removed.
| Stage | What Happens | Reversible? |
|---|---|---|
| Gingivitis | Gums are red, swollen, and bleed easily. No bone loss. | Yes, fully reversible |
| Mild periodontitis | Gums start pulling away. Shallow pockets form. Early bone loss begins. | No, but manageable with treatment |
| Moderate periodontitis | Deeper pockets. More bone loss. Teeth may start to shift. | No, but progression can be slowed |
| Advanced periodontitis | Significant bone loss. Teeth become loose. Extraction may be needed. | No. May require surgery. |
Warning Signs to Watch For
Gum disease can develop without obvious discomfort. Knowing the warning signs makes early detection possible.
- Red, swollen, or tender gums
- Bleeding when you brush or floss
- Gums pulling away from your teeth (recession)
- Persistent bad breath or a bad taste in your mouth
- Loose or shifting teeth
- Changes in how your teeth fit together when you bite
- Pus between your teeth and gums
If you notice any of these, schedule a dental visit. Early treatment makes a significant difference. Waiting until you have loose teeth means the disease has progressed further than it needed to.
Can Periodontal Disease Be Reversed?
Gingivitis is fully reversible. A professional cleaning to remove plaque and tartar, combined with daily brushing and flossing, can restore your gums to health. Once the disease has progressed to periodontitis and bone loss has occurred, the damage can’t be undone. But treatment can stop the progression and prevent further loss.
Treatment for periodontitis typically starts with scaling and root planing. That’s a deep cleaning where your dental team removes tartar from below the gumline and smooths the root surfaces so the gums can reattach. Your dentist may also prescribe antimicrobial rinses or place medication directly into the gum pockets. More advanced cases may need surgical treatment to reduce pocket depth.
The key is catching it early. Regular dental visits give your dentist the chance to find gum disease while it’s still reversible.
How to Protect Your Gums
Prevention starts with the basics. Brush twice a day with fluoride toothpaste, floss every day, and keep up with your regular dental visits. Professional cleanings remove tartar that brushing alone can’t reach. If you smoke, quitting is one of the most impactful things you can do for your gum health.
If you’re in the Rohnert Park area and it’s been a while since your last exam, getting back on a regular schedule is a good first step toward protecting your gums and keeping your teeth where they belong.
