How Gum Disease Progresses
Gum disease starts when bacterial plaque builds up along and below the gum line. The body's immune response to this bacteria causes inflammation, which over time can destroy the tissues and bone that support your teeth. Understanding the stages helps you recognize what level of treatment you may need.
Dental professionals classify gum disease into stages based on how much attachment loss and bone loss has occurred. The 2018 classification system adopted by the American Academy of Periodontology uses Stages I through IV, with each stage reflecting increasing severity and complexity of treatment.
Gingivitis: The Reversible Stage
Gingivitis is gum inflammation without bone loss. This is the only stage where the damage is fully reversible. Gums may appear red, swollen, or bleed when you brush or floss. There is no pain in most cases, which is why many people do not realize they have it.
Professional Treatment for Gingivitis
A professional dental cleaning (prophylaxis) removes the plaque and tartar (calculus) that brushing alone cannot reach. Your dental hygienist will scale above and just below the gum line. In most cases, one to two cleaning visits are enough to resolve gingivitis when combined with improved daily oral hygiene.
Your dentist may also recommend an antimicrobial mouth rinse containing chlorhexidine to reduce bacterial levels during the healing phase. Follow-up visits are typically scheduled every 3 to 6 months to monitor your gums.
Home Care for Gingivitis
Professional cleaning addresses existing buildup, but preventing recurrence depends on daily habits. Brush twice a day with a soft-bristled or electric toothbrush for at least two minutes. Floss daily, reaching below the gum line. An interdental brush or water flosser can help if traditional floss is difficult to use.
Gingivitis Treatment Cost
A standard prophylactic cleaning ranges from $75 to $200 per visit. Most dental insurance plans cover two cleanings per year at little or no out-of-pocket cost. If more frequent cleanings are needed, additional visits may or may not be covered depending on your plan.
Stage I (Early Periodontitis): Scaling and Root Planing
Early periodontitis means the infection has moved below the gum line and begun to damage the bone and connective tissue that hold teeth in place. Pocket depths (the space between the gum and tooth) measure 4 to 5 millimeters, and there is mild bone loss visible on X-rays. Unlike gingivitis, this bone loss is permanent, but treatment can stop further progression.
What Is Scaling and Root Planing?
Scaling and root planing (SRP), commonly called a deep cleaning, is the standard non-surgical treatment for early periodontitis. During scaling, the hygienist or periodontist removes plaque and tartar from below the gum line, reaching into the periodontal pockets. Root planing smooths the root surfaces so the gum tissue can reattach more effectively.
The procedure is typically done in two visits, treating one half of the mouth per visit. Local anesthesia is used to keep you comfortable. Each appointment takes about 45 to 90 minutes. Your gums may feel tender for a few days afterward.
Cost of Scaling and Root Planing
Scaling and root planing typically costs $200 to $400 per quadrant (quarter of the mouth). A full-mouth deep cleaning ranges from $800 to $1,600. Most dental insurance plans cover SRP as a periodontal treatment, though you may have a copay or deductible. Costs vary by location and provider.
Stage II-III (Moderate Periodontitis): SRP Plus Possible Surgery
Moderate periodontitis involves pocket depths of 5 to 7 millimeters, moderate bone loss, and possible tooth mobility. The disease has progressed to the point where non-surgical treatment alone may not be sufficient. Your periodontist will typically start with scaling and root planing and re-evaluate after 4 to 6 weeks.
When Gum Surgery Becomes Necessary
If pockets remain deeper than 5 millimeters after scaling and root planing, your periodontist may recommend flap surgery (also called pocket reduction surgery). During this procedure, the gum tissue is folded back, the infected tissue and bacteria are removed, and the bone surface is smoothed. The gums are then repositioned and sutured to fit more snugly around the teeth.
Flap surgery reduces pocket depth and makes it easier to keep the area clean. In some cases, the periodontist also places bone graft material to help regenerate lost bone. Recovery takes 1 to 2 weeks, with full tissue maturation occurring over several months.
Treatment Costs for Moderate Periodontitis
Scaling and root planing costs remain the same ($800 to $1,600 for a full mouth). If flap surgery is needed, expect $1,000 to $3,000 per quadrant depending on complexity. Bone grafting adds $500 to $1,500 per site. Insurance may cover a portion of these surgical procedures. Total out-of-pocket costs for moderate periodontitis treatment can range from $1,500 to $5,000 or more. Costs vary by location and provider.
Stage III-IV (Severe Periodontitis): Surgery and Regeneration
Severe periodontitis features pocket depths exceeding 7 millimeters, significant bone loss (often more than 50% around affected teeth), tooth mobility, and possible tooth migration or drifting. At this stage, some teeth may not be salvageable.
Surgical Treatment Options
Flap surgery is almost always required in severe cases. In addition, your periodontist may use guided tissue regeneration (GTR), a technique that places a membrane between the bone and gum tissue to direct new bone growth into the defect. Bone grafts, either from your own bone, donor bone, or synthetic material, are commonly placed at the same time.
Enamel matrix derivative (such as Emdogain) is another regenerative option. This protein-based material is applied to the root surface during surgery to stimulate the growth of new periodontal attachment. Your periodontist will recommend the regenerative approach best suited to your bone defect pattern.
When Teeth Cannot Be Saved
Teeth with advanced bone loss, severe mobility, or recurring infections despite treatment may need to be extracted. Holding onto a tooth that cannot be maintained can put neighboring teeth at risk. After extraction, replacement options include dental implants, bridges, or dentures.
If you need implants after severe periodontitis, the gum disease must be fully controlled before implant placement. Bone grafting at the extraction site is often necessary. A periodontist and prosthodontist frequently coordinate care in these cases.
Cost of Treating Severe Periodontitis
Treatment costs for severe periodontitis vary widely depending on how many teeth are affected and which procedures are needed. Regenerative surgery can cost $1,500 to $5,000 per area treated. Extractions range from $150 to $400 per tooth. Implant replacement for lost teeth adds $3,000 to $6,000 per implant. Full treatment plans for severe cases can exceed $10,000. Costs vary by location and provider.
Ongoing Maintenance After Gum Disease Treatment
Gum disease cannot be cured once it has progressed beyond gingivitis. It can be controlled, but it requires ongoing professional maintenance. After active treatment, your periodontist will place you on a periodontal maintenance schedule, typically every 3 to 4 months.
Periodontal maintenance visits include measuring pocket depths, cleaning above and below the gum line, and monitoring for signs of recurrence. These visits are different from standard dental cleanings and are specifically designed for patients with a history of periodontitis. Skipping maintenance appointments is the most common reason gum disease returns.
Periodontal maintenance visits typically cost $150 to $300 each. Many insurance plans cover some of these visits, though they may alternate with regular dental cleanings for coverage purposes.
When to See a Periodontist
A general dentist can diagnose and treat gingivitis and perform scaling and root planing for mild cases. A periodontist should be involved when gum disease has not responded to initial treatment, when pockets remain deep after deep cleaning, or when surgery may be needed.
You should also see a periodontist if you have risk factors that complicate gum disease, such as diabetes, smoking, or a family history of periodontitis. Periodontists complete 3 years of additional residency training beyond dental school focused on treating the gums, bone, and supporting structures of the teeth.
