Periodontal therapy is a category of dental treatments designed to address infection and disease in the gums and supporting structures that hold your teeth in place. It ranges from non-surgical deep cleanings to more advanced surgical procedures, depending on how far the disease has progressed. Below, we answer the most common questions about the types of periodontal therapy, how they work, and what to expect.
What is periodontal therapy, and who actually needs it?
Periodontal therapy refers to specialized dental treatments that target gum disease and the tissues surrounding your teeth, including the gums, bone, and ligaments. Unlike a routine cleaning that addresses the surfaces of the teeth, periodontal therapy goes deeper to remove infection and restore tissue health. It is recommended when gum disease has progressed beyond what standard hygiene appointments can address.
Gum disease develops in stages. Gingivitis is the earliest and most reversible stage, characterized by red, swollen, or bleeding gums. When left untreated, it can advance into periodontitis, where the infection spreads below the gumline and begins to damage the bone and connective tissue supporting your teeth.
Common signs that may prompt a recommendation for periodontal therapy include persistent bad breath, gums that bleed when brushing, teeth that feel loose, receding gums, or pockets forming between the teeth and gums. A dentist measures these pockets during an exam to determine the severity of the condition and which type of therapy is appropriate.
What are the main types of periodontal therapy available?
Periodontal therapy is divided into non-surgical and surgical options, with the choice depending on the severity of the disease. Non-surgical approaches are almost always the starting point, with surgical treatment reserved for cases where deeper intervention is necessary.
Non-surgical periodontal therapy options include:
- Scaling and root planing – A deep cleaning procedure that removes plaque and tartar from below the gumline and smooths root surfaces to discourage bacterial buildup.
- Antibiotic therapy – Topical antibiotics placed directly into gum pockets, or systemic antibiotics taken orally, to reduce bacterial infection alongside other treatments.
- Laser-assisted periodontal treatment – Uses focused laser energy to remove infected tissue and bacteria with greater precision and less discomfort than traditional methods.
Surgical periodontal therapy options include:
- Flap surgery – The gum tissue is gently lifted to allow thorough cleaning of deep pockets and bone irregularities before being sutured back into place.
- Bone grafting – Used when periodontitis has caused bone loss, this procedure replaces or encourages regrowth of lost bone to stabilize teeth.
- Soft tissue grafts – Tissue is taken from another area or a donor source to cover exposed roots and restore a healthier gumline.
- Guided tissue regeneration – A membrane is placed between the bone and gum tissue to encourage the body to rebuild lost supporting structures.
How does non-surgical periodontal therapy work compared to surgical options?
Non-surgical periodontal therapy, particularly scaling and root planing, works by physically removing the bacterial deposits that cause infection. A dental professional uses specialized instruments to clean below the gumline, reaching areas that brushing and standard cleanings cannot. Smoothing the root surfaces then makes it harder for bacteria to reattach, allowing the gums to heal and reattach to the tooth.
Most patients experience some sensitivity following a deep cleaning, which typically settles within a few days. Local anesthesia is commonly used to keep the process comfortable. After treatment, the gums gradually tighten, and the inflammation reduces over several weeks.
Surgical intervention becomes necessary when pockets are too deep for instruments to clean effectively or when bone or tissue loss requires physical reconstruction. The decision to move from non-surgical to surgical care is based on how the gums respond after an initial healing period, usually assessed at a follow-up appointment several weeks later.
Recovery from surgical procedures takes longer, often a few weeks, and may involve dietary adjustments and a more structured home care routine. That said, surgical options are generally well tolerated and produce meaningful long-term improvements in gum health when non-surgical methods alone are not enough.
How do you maintain healthy gums after periodontal therapy?
Maintaining the results of periodontal therapy requires consistent care both at home and through regular professional visits. Periodontal maintenance appointments, typically scheduled every three to four months, are essential because gum disease can return without ongoing monitoring and professional cleaning. These visits differ from standard cleanings and are specifically designed to keep treated areas stable.
At home, brushing twice daily with a soft-bristled toothbrush, flossing carefully along the gumline, and using any recommended rinses all support continued healing. Nutrition also plays a role, as a diet rich in vitamins and low in sugar helps the body maintain healthy tissue.
Smoking is one of the most significant factors that undermines gum health and slows healing, so quitting or reducing tobacco use makes a real difference in long-term outcomes. Watch for warning signs such as bleeding gums returning, increased sensitivity, or gums appearing to pull away from the teeth, as these may indicate that the disease is becoming active again.
