Warning
This article provides general educational information about gum disease. It is not a diagnosis, treatment recommendation, or substitute for professional dental or medical advice. Gum disease exists on a spectrum and its treatment depends on factors specific to each patient. If you have symptoms you are concerned about, please consult a licensed dentist or periodontist. Only a professional clinical examination can accurately assess the state of your gum health.
Gum disease - a broad term for infection and inflammation of the structures that surround and support the teeth - affects close to half of US adults aged 30 and older, according to data from the Centers for Disease Control and Prevention. The condition ranges from mild, reversible gingivitis to advanced periodontitis, which can cause permanent bone loss and eventually tooth loss if left untreated. Understanding the stages, recognizing possible symptoms, and knowing what treatment generally involves can help you have a more productive conversation at your next dental appointment.
What Is Gum Disease?
Gum disease, known clinically as periodontal disease, is caused by bacterial plaque - the sticky film that forms on teeth and hardens into tartar when not removed consistently through brushing and flossing. The American Academy of Periodontology explains that this bacterial accumulation triggers an inflammatory response in the gum tissue that, over time, can spread below the gumline and damage the bone and connective tissue that hold teeth in place.
The two main categories are:
Gingivitis: Inflammation limited to the gum tissue without bone loss. This is the earliest and most reversible stage. Most people experience some level of gingivitis at some point, and it typically responds well to improved oral hygiene and professional cleaning.
Periodontitis: Inflammation that has progressed to involve the underlying bone and periodontal ligament. Bone loss that has occurred cannot be regenerated by cleaning alone. However, with appropriate professional treatment and consistent maintenance, the progression of periodontitis can generally be controlled and the remaining supporting tissue preserved.

Common Symptoms of Gum Disease
Many patients first notice gum disease symptoms on their own, though in early stages the condition can progress silently. The American Academy of Periodontology lists the following as commonly associated symptoms:
- Gums that bleed during or after brushing or flossing
- Red, swollen, or tender gum tissue
- Gums that have pulled away or appear to have receded from the tooth surface
- Persistent bad breath not resolved by brushing
- Loose or shifting teeth (in more advanced cases)
- Changes in the way teeth fit together when biting
- Sensitivity along the gumline
It is worth noting that some patients with significant bone loss show no pain and minimal visible inflammation. This is one reason regular dental check-ups - which include probing to measure pocket depths around each tooth - remain the most reliable way to detect gum disease early.
What Causes Gum Disease?
Bacterial plaque is the primary cause. When plaque is not removed consistently through daily brushing and flossing, it mineralizes into tartar (calculus) that adheres firmly to tooth surfaces and cannot be removed by home care alone. Tartar accumulation provides a surface for more bacterial growth, driving the inflammatory cycle.
Several factors increase susceptibility to gum disease, according to the National Institute of Dental and Craniofacial Research. Smoking is one of the strongest risk factors - tobacco use impairs the gum tissue's ability to heal and respond to treatment. Poorly controlled diabetes affects the body's inflammatory response and healing capacity. Certain medications that cause dry mouth or gum tissue changes (some antihypertensives, antidepressants, and anticonvulsants) can also increase risk. Genetic susceptibility means that some individuals are more prone to gum disease even with good oral hygiene habits.
How Is Gum Disease Diagnosed?
A dental professional diagnoses gum disease through a clinical examination that includes several components:
Periodontal probing. A small calibrated instrument called a periodontal probe is gently inserted between the tooth and gum tissue to measure the depth of the sulcus (the natural groove) or periodontal pocket. Healthy tissue typically produces measurements of one to three millimeters. Depths of four millimeters or more are associated with disease, and depths of six or more generally indicate significant attachment loss.
X-rays. Bitewing and periapical X-rays allow the dentist to evaluate bone levels around each tooth. Bone loss that is not yet clinically visible can often be detected radiographically, making X-rays an important diagnostic tool alongside probing.
Visual examination. The color, contour, and texture of the gum tissue provide additional diagnostic information. Healthy gum tissue is typically firm and pink; inflamed tissue may appear redder, shinier, and more swollen.
Treatment Options and What They Cost
The appropriate treatment depends on the severity of the disease. The American Academy of Periodontology describes a spectrum of treatment options from basic non-surgical care to advanced surgical intervention.
Professional cleaning (prophylaxis) for gingivitis. When disease is limited to gingivitis with no bone involvement, a standard professional cleaning combined with improved home care is often sufficient to resolve the inflammation. A routine cleaning (CDT code D1110 for adult prophylaxis) is typically covered as a preventive benefit by most dental insurance plans.
Scaling and root planing (deep cleaning). This is the first-line non-surgical treatment for periodontitis. The procedure involves removing bacterial deposits from below the gumline and smoothing the root surfaces to discourage bacterial reattachment. It is performed by quadrant - typically one or two quadrants per appointment with local anesthesia. Humana dental resources cite a typical cost of $150 to $350 per quadrant without insurance based on national ADA fee survey data. A full-mouth treatment involves four quadrants, bringing the total non-surgical treatment cost to roughly $600 to $1,400.
Our guide on deep cleaning dental cost covers scaling and root planing in more detail, including what to expect during the procedure.
Periodontal maintenance. After completing scaling and root planing, most periodontitis patients transition to periodontal maintenance (CDT code D4910) every three to four months. The American Academy of Periodontology notes that this ongoing schedule - rather than a return to twice-yearly standard cleanings - is typically recommended for life in patients who have had active periodontitis. Maintenance visit fees are commonly $100 to $300 per visit and may or may not be covered at the same benefit level as a preventive cleaning, depending on your insurance plan.
Periodontal surgery. In cases where non-surgical treatment does not adequately resolve deep pockets or where bone defects require correction, a periodontist may recommend surgical procedures such as flap surgery (to access and clean root surfaces directly), bone grafting to address lost bone, or tissue regeneration procedures. Surgical fees vary significantly by procedure type and are typically covered at the major restorative benefit level.

Can Gum Disease Be Reversed?
Gingivitis is reversible. With consistent and thorough brushing, daily flossing, and a professional cleaning to remove established tartar, most cases of gingivitis resolve and the tissue returns to a healthy state. Our guide on how to prevent cavities covers the home care fundamentals that also benefit gum health.
Periodontitis, which involves loss of bone and connective tissue, cannot be reversed in the sense of fully regenerating lost tissue. However, it can be controlled. Non-surgical and surgical treatment, combined with ongoing professional maintenance and improved home care, can typically halt or significantly slow disease progression and preserve the remaining supporting structures for years or decades.
The American Academy of Periodontology frames the goal of periodontitis treatment as stabilization and maintenance - achieving a state where the patient's tissue levels are stable and the disease is not actively progressing. This is a meaningful outcome for most patients, even if full restoration of lost bone is not possible.
How to Reduce Your Risk of Gum Disease
The American Dental Association and CDC oral health guidance consistently identify the following as evidence-based practices for gum disease prevention:
Brush twice daily using a fluoride toothpaste and a soft-bristled brush. Angle the brush toward the gumline to clean the sulcus area where bacteria accumulate. Brushing technique matters as much as frequency.
Floss daily. Dental floss reaches the spaces between teeth and just below the gumline that a toothbrush cannot access. Our guide on how to floss correctly describes technique.
Attend professional cleanings consistently. Even excellent home care leaves some tartar that only professional instruments can remove. For most adults with healthy gums, twice-yearly cleanings are the ADA-recommended baseline. Patients with a history of gum disease typically require more frequent care.
Quit smoking. The American Academy of Periodontology notes that smokers are significantly more likely to develop gum disease and respond less favorably to treatment than non-smokers. Smoking cessation is one of the most impactful steps a patient can take for gum health.
Manage systemic health. Keeping diabetes well-controlled, informing your dentist of all medications, and managing conditions that affect immune function all support gum health. Your medical and dental providers should have a shared picture of your health.
Warning
Talk to your dentist or periodontist. If you have symptoms that concern you - bleeding gums, gum recession, loose teeth, or persistent bad breath - bring them up at your next dental visit. Do not delay seeking care because you are unsure whether symptoms are serious. Only a clinical examination that includes periodontal probing and X-rays can accurately assess the state of your gum health. Early treatment is significantly more straightforward - and less costly - than treatment after advanced disease has set in.
Frequently asked questions
What are the early signs of gum disease?
The American Academy of Periodontology identifies the most common early signs of gum disease as gums that bleed during brushing or flossing, redness or swelling of the gum tissue, and persistent bad breath. These symptoms can appear with gingivitis - the mildest and most reversible stage - but they are not always noticeable without a professional examination. Bleeding gums are particularly worth mentioning to your dentist at your next scheduled visit.
Can gum disease be reversed with brushing and flossing?
Gingivitis - the earliest stage of gum disease - is typically reversible with consistent brushing, flossing, and professional cleaning, according to the American Dental Association. More advanced gum disease, classified as periodontitis, involves damage to the bone and connective tissue that support the teeth. This damage cannot be fully reversed, but it can generally be controlled and stabilized with appropriate professional treatment and ongoing maintenance.
What is the difference between gingivitis and periodontitis?
Gingivitis is inflammation confined to the gum tissue itself, with no loss of bone or connective tissue. It is the earliest and most reversible stage. Periodontitis is a more serious condition in which the inflammation has progressed below the gumline, causing the bone and connective tissue that anchor the teeth to break down, according to the American Academy of Periodontology. Left untreated, periodontitis can lead to tooth loosening and eventually tooth loss.
How much does gum disease treatment cost?
Treatment cost depends on the severity of the condition. A professional cleaning for early gingivitis is typically covered under a standard preventive benefit. Scaling and root planing - the deep cleaning used for periodontitis - costs approximately $150 to $350 per quadrant without insurance based on American Dental Association CDT data and published ranges from Humana dental resources. Advanced cases may require periodontal surgery, which carries higher fees.
Does gum disease affect overall health?
Research published by the National Institute of Dental and Craniofacial Research and reviewed by the American Academy of Periodontology has found associations between periodontal disease and systemic conditions including cardiovascular disease, diabetes, and adverse pregnancy outcomes. Scientists are still working to clarify whether the relationship is causal or correlational. Current guidance from the ADA and AAP recommends treating gum disease on its own merits while noting the potential broader health implications.
How often should someone with gum disease see a dentist?
Patients who have been treated for periodontitis typically require more frequent professional maintenance than the standard twice-yearly schedule for healthy patients. The American Academy of Periodontology recommends periodontal maintenance appointments - usually every three to four months - to monitor tissue health, remove bacterial buildup that regular home care cannot reach, and catch any signs of disease reactivation early. Your provider will recommend a frequency based on your specific case.
What is a periodontal maintenance appointment?
A periodontal maintenance appointment is a professional cleaning and monitoring visit designed specifically for patients who have been treated for gum disease. It involves cleaning above and below the gumline, measuring pocket depths around each tooth to assess tissue health, and updating your dentist or periodontist on any changes since the last visit. CDT code D4910 designates this service as distinct from a standard prophylaxis cleaning.
