Gum Disease Treatment: What to Expect at Each Stage

What Gum Disease Actually Is

Gum disease is a bacterial infection of the tissues surrounding the teeth. The bacteria responsible live in dental plaque — the soft film that forms on teeth within hours of cleaning. When plaque is not consistently removed, it accumulates at and below the gum line and triggers an immune response in the surrounding gum and bone tissue.

The disease progresses in stages. In its mildest form, gum disease (gingivitis) affects only the gum tissue itself and is fully reversible. As it advances, the infection spreads below the gum line into the bone and ligament that attach the teeth to the jaw — this is periodontitis, and the destruction it causes is not reversible. In its most severe form, periodontitis destroys enough supporting structure to cause tooth mobility and ultimately tooth loss.

Gum disease is the leading cause of tooth loss in Australian adults, with the Australian Institute of Health and Welfare (AIHW) reporting that nearly 1 in 4 Australian adults have moderate to severe periodontitis. It is also associated with systemic health conditions including cardiovascular disease, diabetes complications, and adverse pregnancy outcomes. Treatment is well-established, evidence-based, and highly effective at stopping disease progression when followed up with appropriate maintenance. The Australian Dental Association provides consumer information on gum disease prevention and treatment.

Recognising the Stages

Gingivitis

The earliest form of gum disease, confined to the gum tissue without involving bone. Characteristics:

• Gums bleed easily when brushing or flossing
• Gums appear red, swollen, or puffy at the edges
• Gums may feel tender
• Some patients notice bad breath or a metallic taste
• No bone loss has occurred — the condition is fully reversible

Many patients with gingivitis have few or no symptoms. Bleeding gums are often dismissed as “normal” when in healthy gum tissue, bleeding with routine brushing does not occur.

Mild to moderate periodontitis

The infection has spread below the gum line, causing the body’s immune response to begin destroying the bone and ligament supporting the teeth. A “pocket” develops between the tooth and gum — normally 1 to 3 mm deep; in periodontitis, these deepen to 4 to 7 mm or more, providing a sheltered environment where bacteria thrive beyond reach of a toothbrush.

Signs:

• Persistent bad breath
• Continued bleeding despite adequate brushing
• Gums appearing to recede (teeth look longer)
• Sensitivity to cold or air at the gum line
• Occasional dull aching around the gums
• X-rays showing bone loss between teeth

Much mild periodontitis is asymptomatic until significant damage has occurred. Regular dental checkups — which include measuring pocket depths and checking bone levels on radiographs — are the most reliable way to detect it early.

Advanced periodontitis

Significant bone and attachment loss has occurred. Teeth may be mobile. Deep pockets (7 mm or more) exist that are extremely difficult to maintain clean. Some teeth may be beyond saving.

Signs:

• Noticeable tooth movement or widening gaps between teeth
• Teeth shifting position
• Food consistently packing into specific areas
• Painful chewing
• Pus around some teeth
• Tooth loss in severe cases

Treatment by Stage

Gingivitis treatment

Professional scale and clean. Removal of plaque and calculus (hardened plaque/tartar) from all tooth surfaces, including just below the gum line. This removes the bacterial load driving the inflammation.

Home care instruction. Brushing technique review and flossing or interdental brush instruction. Gingivitis treated with professional cleaning alone will return if home plaque control does not improve.

Review at 4 to 6 weeks. In most patients with gingivitis, a professional clean plus improved home care resolves the condition completely within 4 to 6 weeks. Gum tissue returns to a healthy, pale pink, non-bleeding appearance.

Cost in Townsville: $150 to $300 for the professional clean. See the dental cleaning cost Townsville guide for itemised costs.

Mild to moderate periodontitis treatment

Scaling and root planing (SRP). The primary non-surgical treatment for periodontitis. Under local anaesthesia, the dentist or hygienist uses specialised instruments to clean thoroughly below the gum line — reaching to the base of each periodontal pocket, removing calculus from root surfaces, and disrupting the bacterial biofilm. Root surfaces are smoothed (planed) to reduce bacterial reattachment.

SRP is typically done in quadrants (dividing the mouth into four areas) over 2 to 4 appointments. Most patients require 2 to 4 appointments over 2 to 4 weeks.

Local antimicrobials. In some cases, antimicrobial agents (chlorhexidine chips, antibiotic gels) are placed directly into pockets after SRP to supplement mechanical cleaning. These are not routinely required but benefit specific sites.

Review at 6 to 8 weeks. After SRP and a healing period, pockets are re-measured. Most pockets improve by 1 to 2 mm. Sites where pockets remain deep (6 mm or greater) despite treatment are assessed for surgical management.

Cost in Townsville: $800 to $2,000 for full-mouth SRP, depending on severity.

Advanced periodontitis — surgical management

When non-surgical treatment fails to control disease adequately — pockets remain too deep to instrument or maintain — surgical access is considered.

Periodontal flap surgery. The gum tissue is lifted (a flap is raised) under local anaesthesia, providing direct visual access to root surfaces and bone. Calculus and diseased tissue are removed under direct vision. The flap is repositioned and sutured. Pocket depth is effectively reduced by repositioning the gum tissue at a lower level and removing diseased tissue.

Regenerative procedures. In some bone defects — particularly vertical defects where bone has been lost in a localised pattern around a specific tooth root — regenerative techniques aim to regrow bone and attachment tissue. These use membranes (guided tissue regeneration), bone graft materials, or growth factor proteins to encourage the body’s healing response. Not all defects are suitable; regeneration is site-specific and outcome is variable.

Crown lengthening. A surgical procedure that exposes more tooth structure by repositioning the gum. Sometimes required before crown placement when a tooth is damaged below the gum line.

Extractions. Teeth with insufficient bone support to be maintained long-term, or with furcation involvement (bone loss between the roots of multi-rooted teeth) that cannot be managed, may need to be extracted. Teeth with less than 50 per cent bone support remaining, or with Class III furcation involvement, are typically assessed for extraction.

Cost in Townsville: $1,500 to $4,000 per surgical area; full-mouth management $4,000 to $10,000.

Long-Term Maintenance: The Critical Phase

Treatment for periodontitis is not a one-time event. Once periodontitis is active, the patient is at elevated risk of reactivation for the rest of their lives — the bacteria responsible return and the immune response in susceptible patients allows disease recurrence if maintenance lapses.

Periodontal maintenance (also called supportive periodontal therapy) consists of professional cleaning appointments specifically designed for patients with a history of periodontitis. These differ from routine scale and cleans:

• Pocket depths are measured at every visit
• Bleeding sites and disease activity are recorded
• Subgingival cleaning is performed at any sites showing activity
• Home care adherence is assessed and reinforced
• Any changes from previous visits are identified and addressed early

Frequency: Every 3 to 4 months for most patients with a history of periodontitis. This is not negotiable — patients who extend to 6-monthly intervals have significantly higher rates of disease reactivation. Studies indexed on PubMed consistently show that the 3 to 4 month maintenance interval is the evidence-based standard for periodontitis patients.

Duration: Indefinite. Periodontitis does not enter remission permanently. The condition can be controlled with maintenance but not “finished.” Patients sometimes struggle to accept that they will need more frequent professional cleaning for life; understanding the biological reason (persistent bacterial susceptibility and immune response) helps with long-term adherence.

Risk Factors and Their Management

Gum disease risk is elevated by modifiable and non-modifiable factors. Addressing modifiable factors significantly improves treatment outcomes.

Gum Disease and Dental Implants

Patients with a history of periodontitis who receive dental implants require particular vigilance. The bacteria responsible for periodontitis are also the primary cause of peri-implantitis — the implant equivalent of periodontitis. Patients with untreated active periodontitis should not receive implants; those who have had periodontitis treated and controlled can receive implants but need enhanced maintenance.

If you are considering dental implants and have a history of gum disease, discuss this history with the treating implant dentist. See the dental implant candidates: are you eligible guide for a full discussion of candidacy, including the role of gum health.

Finding a Periodontist in Townsville

Mild gingivitis and mild periodontitis can be managed effectively by a general dentist or dental hygienist with appropriate training. Advanced or complex periodontitis — particularly cases requiring surgical management, cases with multiple risk factors, or cases where previous treatment has failed — may benefit from referral to a periodontist (a dental specialist in gum disease and periodontal surgery).

Townsville has limited specialist periodontic services; patients requiring specialist-level care may be referred to Townsville Periodontics in Currajong or to Brisbane for complex cases. A general dentist managing periodontitis can make this assessment and refer as needed.
