Gum disease is an infection of the tissues that hold your teeth in place, and its early signs are easy to miss: gums that bleed when you brush or floss, look red or puffy, or leave you with stubborn bad breath. Caught early, in a stage called gingivitis, it can usually be reversed with better cleaning habits and a professional cleaning. Left alone, it can progress to periodontitis, which can damage the bone that supports your teeth and lead to tooth loss.
Key Takeaways
- Bleeding gums are not normal, even if they bleed only a little. They are a common first warning.
- Gingivitis, the mild stage, is reversible. Periodontitis can be controlled but the bone and tissue it destroys do not fully grow back on their own.
- Plaque is the main cause, and smoking, diabetes, some medicines, hormonal changes and genetics raise your risk.
- Treatment ranges from a thorough cleaning to deep cleaning (scaling and root planing) and, for advanced cases, surgery.
- Daily brushing, cleaning between teeth and regular dental visits are the best defense, and many dental plans cover parts of treatment.
How Gum Disease Starts
Your mouth is home to bacteria that form a sticky film called plaque on your teeth. If plaque is not removed each day, it hardens into tartar (also called calculus), which a toothbrush cannot remove. Bacteria in plaque and tartar irritate the gums, and your body responds with inflammation.
The disease is often painless, which is why people can have it for a long time before noticing. By the time a tooth feels loose or sore, the condition may be well along. This is why dental checkups matter even when nothing hurts.
Gum Disease Signs and Symptoms
Watch for any of the following, and mention them to a dentist.
- Gums that bleed during brushing, flossing or eating
- Red, swollen, shiny or tender gums
- Persistent bad breath or a bad taste that brushing does not fix
- Gums pulling away from the teeth, making teeth look longer
- Pus between teeth and gums
- Teeth that feel loose or shift position, or a change in how your bite fits together
- Pain when chewing
A single symptom does not confirm gum disease, since brushing too hard or a new floss routine can briefly cause bleeding. If bleeding or swelling lasts more than a week or two, get it checked.
The Stages of Gum Disease
Dentists usually describe a progression. Your dentist or hygienist measures the gaps (pockets) between your teeth and gums with a small probe and may take X-rays to check bone levels.
| Stage | What is happening | Typical signs | Usual approach |
|---|---|---|---|
| Gingivitis | Inflammation limited to the gums | Red, puffy gums that bleed easily, no bone loss | Professional cleaning and improved home care |
| Early periodontitis | Gums begin to pull away, small pockets form, slight bone loss | Bleeding, mild recession, bad breath | Deep cleaning and closer monitoring |
| Moderate periodontitis | Deeper pockets and more bone loss | Recession, swollen gums, possible looseness | Scaling and root planing, sometimes added medication |
| Advanced periodontitis | Significant bone loss, teeth may shift or loosen | Pus, loose teeth, pain with chewing | Specialist care, possibly surgery or extraction |
Dental professionals now also grade periodontitis by how fast it is progressing and by risk factors, so your diagnosis may use terms beyond these four. Ask your dentist to explain your specific stage.
Who Is at Higher Risk
Anyone can develop gum disease, but some factors raise the odds.
- Tobacco use. Smoking and vaping nicotine are strongly linked to gum disease and to poorer healing.
- Diabetes. High blood sugar makes infections harder to control, and gum disease can in turn make blood sugar harder to manage.
- Dry mouth. Many medicines reduce saliva, which normally helps wash away bacteria.
- Hormonal changes. Pregnancy, puberty and menopause can make gums more sensitive.
- Genetics and age. Some people are more prone, and risk rises with age.
- Crowded teeth or poor-fitting dental work. These can trap plaque.
- Stress and poor nutrition. They may affect your body’s ability to fight infection.
Researchers have noted associations between periodontitis and conditions such as heart disease and diabetes. An association does not prove that gum disease causes those conditions, but caring for your gums is a reasonable part of caring for your overall health.
What Happens During a Gum Exam
If you have never had a thorough gum evaluation, knowing the routine takes some worry out of it. The hygienist or dentist gently measures the depth of the space around each tooth, usually at six points per tooth. Healthy pockets are shallow, while deeper readings suggest the gum has detached from the tooth. They also note whether the gums bleed during the measurement, check for recession and test whether any teeth move.
X-rays show the level of bone around the roots, which is how clinicians tell gingivitis from periodontitis. You may also be asked about smoking, medications, diabetes and family history. Be candid, since these details shape your treatment plan.
Common Myths About Gum Disease
- “Bleeding means I should brush less.” Bleeding usually means inflammation, and gentle, regular cleaning is what helps. Brushing harder is not the answer, though, since aggressive scrubbing can wear the gums.
- “It only affects older people.” It becomes more common with age, but gingivitis can appear in teens and young adults.
- “No pain means no problem.” Early gum disease is often painless.
- “Natural remedies replace dental care.” Oil pulling, herbal rinses and similar home remedies have not been shown to remove tartar or treat established disease. They should not replace a dental visit.
- “Whitening or cleaning products fix it.” Cosmetic products do not treat infection. If you want to brighten your smile, treat gum problems first, then read our guide on how to whiten teeth naturally at home for gentle options.
Foods and Habits That Affect Your Gums
No food cures gum disease, but your overall diet matters. Frequent sugary snacks and drinks feed plaque bacteria, while crunchy fruits and vegetables, dairy and plenty of water support a cleaner mouth. Water also helps if your mouth is dry. Vitamin C deficiency can cause gum problems, so a varied diet with fruits and vegetables is worthwhile, but taking extra supplements will not treat established gum disease.
Grinding or clenching your teeth can stress gums and the bone around the teeth. If you wake with jaw soreness, tell your dentist, who may suggest a night guard.
Treatment Options
The right treatment depends on your stage. Your dentist or a periodontist (a gum specialist) will explain the choices and their costs before you begin.
For gingivitis
A professional cleaning removes plaque and tartar, and a better home routine often restores healthy gums within a couple of weeks. Your dentist may suggest an antibacterial mouth rinse for a limited time.
For periodontitis
- Scaling and root planing. A deep cleaning that removes plaque and tartar below the gumline and smooths the root surfaces so gums can reattach. It is often done one section of the mouth at a time, sometimes with local anesthetic.
- Medication. A dentist may place antibiotic material in pockets or prescribe antibiotics or special rinses in some cases. Take any prescription exactly as directed.
- Surgery. For deeper pockets, procedures such as flap surgery clean beneath the gums and reshape bone, and grafts can rebuild lost tissue or bone.
- Maintenance visits. After active treatment, many patients return every three to four months for periodontal maintenance cleanings, rather than the usual six-month interval.
Treatment aims to stop the disease and keep your teeth. Results depend on how well the disease is controlled at home and whether risk factors like smoking continue.
What Gum Disease Treatment May Cost
Costs differ by region, provider and severity, so treat these as rough ranges and ask for a written estimate. A routine cleaning for gingivitis is usually the least expensive step. Scaling and root planing is commonly billed per quadrant of the mouth, and the total for a full mouth can run into the high hundreds or low thousands of dollars. Surgery and grafting generally cost more.
Many dental plans cover cleanings at a high percentage and deep cleanings at a lower one, with annual maximums that can run out quickly.

Daily Habits That Protect Your Gums
- Brush twice a day for two minutes. Use a soft-bristled brush and fluoride toothpaste, angling the bristles toward the gumline with gentle strokes.
- Clean between your teeth daily. Floss, interdental brushes or a water flosser all work. Choose the one you will use consistently.
- Replace your brush regularly. About every three months, or sooner if bristles fray.
- Do not smoke. If you want to quit, ask your clinician about support options.
- Keep dental appointments. Most adults benefit from checkups and cleanings once or twice a year, or as often as your dentist advises.
- Manage health conditions. Keep diabetes under control and mention any medicines that dry your mouth.

When to See a Dentist Urgently
Book a visit soon if you have bleeding gums that last, loose teeth, persistent bad breath or gums that recede. Seek prompt care for a swollen, painful area with pus, a bad taste with fever, or facial swelling, since these can signal an abscess. If swelling spreads toward your eye or neck, or you have trouble breathing or swallowing, call 911 or go to an emergency room.
Frequently Asked Questions
Can gum disease be reversed?
Gingivitis can be reversed with professional cleaning and good home care. Periodontitis can usually be controlled, but lost bone and gum tissue do not fully return without surgery.
What does early gum disease look like?
Gums may look red or puffy and bleed when you brush or floss. You might notice bad breath, but there is often no pain.
Is gum disease contagious?
The bacteria involved can pass through saliva, but whether you develop disease depends on your own risk factors and oral hygiene.
Does mouthwash cure gum disease?
No. Rinses can help reduce plaque or bacteria as a supplement, but they cannot remove tartar or replace brushing and cleaning between teeth.
How long does treatment take?
Gingivitis may improve within a few weeks. Deep cleaning is often split across one to several visits, followed by regular maintenance.
Can I lose teeth to gum disease?
Advanced periodontitis is a leading reason adults lose teeth. Early treatment greatly lowers that risk.
Is bleeding during flossing normal?
It can happen when you start flossing because of inflamed gums, but it should ease within a couple of weeks of consistent cleaning. If it does not, see a dentist.
Does pregnancy affect gums?
Hormonal changes can make gums more prone to swelling and bleeding. Tell your dentist if you are pregnant and keep up routine dental care.
Bottom Line
Gum disease starts quietly, but its signs are visible if you know what to look for: bleeding, redness, swelling, bad breath and receding gums. Treating it early keeps the problem at the reversible stage, and even advanced disease can be controlled with professional care and steady home habits. If you have noticed any symptoms, schedule a dental exam, ask for a clear diagnosis and cost estimate, and make daily cleaning between your teeth part of your routine.
