PeriodontistEdit
Periodontists are dental specialists focused on the prevention, diagnosis, and treatment of diseases affecting the supporting structures of teeth, as well as the placement and maintenance of dental implants. Their work centers on the gums (gingiva), the periodontal ligament, the cementum covering the tooth root, and the maxillary and mandibular alveolar bone that surround and stabilize teeth. They also address soft-tissue and esthetic concerns related to the gums and supporting tissues.
Periodontists collaborate with general dentists and specialists to preserve natural teeth whenever possible and to restore function and aesthetics when periodontal disease or trauma has compromised tooth support. The field encompasses non-surgical and surgical therapies, surgical reconstruction, implantology, and long-term maintenance.
periodontics is the broader discipline, and patients commonly encounter periodontists through referrals from general dentists, especially when a patient presents with signs of periodontal disease, complex gum issues, or when implants are planned.
Education and training
Periodontists complete the standard dental degree program, followed by a specialized residency in periodontics, typically lasting three years in many countries. During advanced training, they gain in-depth experience in:
- Diagnosis and treatment planning for periodontal diseases and implant therapy
- Non-surgical therapies such as scaling and root planing
- Surgical procedures for soft tissue management and bone regeneration
- Placement and restoration considerations for dental implants
- Management of mucogingival conditions and gingival recession
- Periodontal maintenance and long-term disease control
Board certification or credentialing varies by nation or region, but many systems require passing standardized examinations and demonstrating ongoing commitment to clinical excellence and ethics. Board certification and continuing education play important roles in maintaining high standards of care.
Scope of practice
A periodontist’s work spans preventive, diagnostic, therapeutic, and rehabilitative activities. Key components include:
Non-surgical periodontal therapy: cleaning of root surfaces (scaling), smoothing of root surfaces (root planing), and patient education to reduce plaque accumulation. This is often the initial approach for early periodontal disease.
Surgical periodontal therapy: including flap procedures to access diseased bone and tissue, resective approaches to remove diseased tissue, and regenerative techniques to restore lost bone and supportive structures. Surgical subtypes include osseous resection, osseous grafts, and guided tissue regeneration.
Soft-tissue management and mucogingival surgery: addressing gum recession, gummy smiles, frenum malposition, and insufficient attached gingiva to improve function and aesthetics.
Dental implants and rehabilitation: assessment for implant placement, surgical placement of implants, and restorative procedures to integrate implants with teeth or prosthetic solutions. These techniques can be used to replace missing teeth when natural tooth retention is not feasible.
Esthetic periodontal procedures: contouring the gums and reshaping tissue to create natural, harmonious appearances around teeth and implants.
Maintenance and prevention: designing and supervising long-term maintenance programs to prevent recurrence of disease, including regular professional cleanings, monitoring of attachment levels, and patient education.
Adjunctive therapies: use of antibiotics where appropriate, antiseptic agents, and, in some settings, laser-assisted or other adjunctive approaches. The evidence base for some adjuncts varies, and clinicians weigh benefits against risks and costs. See also antibiotics and laser therapy in relation to periodontal care.
Interdisciplinary care: collaboration with general dentistry, orthodontics, prosthodontics, and oral surgery to ensure comprehensive outcomes for function and aesthetics. Related concepts include dental implants and prosthetic planning.
Common conditions managed
Periodontal diseases: including gingivitis and periodontitis, which involve inflammation and destruction of the gums and supporting structures. Links to more information can be found in periodontal disease.
Gum recession and mucogingival problems: conditions affecting the position and health of the gingival tissues.
Bone and tissue loss around teeth or implants: conditions requiring regenerative procedures, bone grafts, or guided tissue regeneration.
Dental implant complications: including peri-implantitis and soft-tissue concerns around implants.
Aesthetic gum concerns: smile line balance, pink esthetics, and tissue contour around teeth and implants.

Controversies and debates
As in many areas of medicine and dentistry, there are ongoing debates among clinicians about the relative value of certain techniques and adjuncts. Examples include:
Use of lasers and adjunctive light-based therapies: While lasers and LED devices are popular in some practices for soft-tissue management and decontamination, systematic reviews show mixed results regarding superior outcomes over conventional methods for many indications. Clinicians weigh potential benefits against cost, patient comfort, and the strength of the evidence. See laser therapy.
Antibiotic use in periodontal therapy: The decision to use systemic antibiotics in conjunction with mechanical therapy remains debated, with concerns about antibiotic resistance balanced against potential improvements in treatment outcomes. This discussion occurs within the framework of evidence-based practice and patient-specific risk factors. See antibiotics.
Timing of implant placement vs traditional periodontal treatment: In some cases, implants offer a reliable solution to tooth loss, but long-term outcomes depend on proper case selection, bone quality, and maintenance. Many clinicians advocate a conservative approach that prioritizes natural tooth preservation when feasible.
Maintenance intensity and patient compliance: The success of periodontal therapy hinges on ongoing maintenance and patient adherence to home care. Debates exist about optimal maintenance intervals and how best to motivate patients to sustain good oral hygiene.
