Short answer
The earliest sign of gum disease is usually gums that bleed when you brush or floss, often with redness, puffiness or bad breath, and usually without pain. At this stage, called gingivitis, a professional cleaning and better daily care can reverse it. Left alone, it can become periodontitis, which damages the bone that holds teeth in place, and that damage cannot be fully undone.
What is gum disease?
Gum disease is an infection of the gums and the tissues that support your teeth. It starts with plaque, the sticky film of bacteria that builds up along the gumline every day. If plaque is not cleaned off, it hardens into tartar, which only a dental cleaning can remove. The bacteria irritate the gums and, over time, the deeper tissues.
The CDC reports that gum disease is common among U.S. adults, and it becomes more common with age. Many people who have it do not know, because it rarely hurts in the early stages.
What are the early warning signs?
- Gums that bleed when you brush, floss or eat hard foods
- Red, swollen or tender gums instead of pink and firm
- Bad breath or a bad taste that does not go away
- Gums that look like they are pulling back from the teeth
- Sensitive teeth near the gumline
Later signs include pus between teeth and gums, teeth that feel loose or are shifting, new gaps, or a change in how your teeth fit together when you bite. Those signs mean the disease has likely moved past the early stage.
Is bleeding when I floss normal?
No. Healthy gums do not bleed with gentle brushing and flossing. A little bleeding when you first start flossing again can happen, and it usually stops within a week or two of daily flossing as the gums calm down. Bleeding that keeps going is a sign to get checked. Our post on why gums hurt after flossing explains more.
How does gingivitis differ from periodontitis?
| Gingivitis (early) | Periodontitis (advanced) | |
|---|---|---|
| What is affected | Gum tissue only | Gums, bone and the fibers holding the teeth |
| Common signs | Bleeding, redness, puffiness | Deep pockets, receding gums, loose teeth, bone loss |
| Pain | Usually none | Often little, until late |
| Reversible? | Yes, with cleaning and home care | Can be controlled, but lost bone does not fully return |
| Typical treatment | Professional cleaning, better brushing and flossing | Scaling and root planing, then periodontal maintenance |

Why does catching it early matter?
You can still reverse it
Gingivitis has not yet damaged the bone. A cleaning, plus steady brushing and flossing, can return your gums to health. Once bone is lost, treatment is about stopping further damage, not restoring what is gone.
You can keep your teeth
Advanced gum disease is a leading cause of tooth loss in adults. Treating it sooner protects the support your teeth need.
Treatment is simpler
Early gum problems usually need only a regular cleaning and exam. Later stages need scaling and root planing, more frequent maintenance visits, and sometimes extractions and tooth replacement. Our guide to what determines the cost of scaling and root planing explains what affects the price.
Your overall health
Research has linked gum disease with diabetes, heart disease and other conditions. People with diabetes also tend to have a harder time controlling gum disease. Scientists are still working out cause and effect, but healthy gums are part of good overall health.
Who is at higher risk?
- People who smoke or vape
- People with diabetes
- Adults over 65
- People taking medicines that cause dry mouth
- Pregnant women, due to hormone changes
- Anyone with a family history of gum disease
If any of these apply, regular checkups matter even more. Older adults can learn more on our senior dentistry page.
How can you prevent gum disease?
- Brush twice a day for two minutes with a soft brush, angled toward the gumline.
- Clean between your teeth once a day with floss, picks or a water flosser.
- Replace your toothbrush every 3–4 months, or sooner if the bristles fray.
- Do not smoke or vape.
- Keep regular checkups and cleanings so tartar is removed before it causes damage.
At our Richmond office we accept most PPO plans and Medicare Advantage plans with dental benefits; see our insurance page. Saturday appointments are available.
When to call us
Book a gum check if your gums bleed when you brush or floss, look red or swollen, are pulling back, or you have bad breath that won’t go away. Call sooner if a tooth feels loose, you see pus, or your gum is painfully swollen, since that can be an abscess. Call (832) 612-2831 — we’re open Tuesday, Wednesday and Saturday, 9am–3pm.
Frequently asked questions
Mild gum irritation can improve with better brushing and flossing, but tartar has to be removed at a cleaning. Without that, gum disease usually keeps progressing.
Mouthwash can help control plaque, but it cannot remove tartar or treat deep pockets. It works as an extra to brushing, flossing and professional care, not a replacement.
The bacteria can be passed through saliva, but whether someone develops gum disease depends mostly on their own habits, health and genetics.
Most people do well with checkups twice a year. If you have gum disease or a higher risk, we may suggest more frequent visits.
