What Is Periodontics Dentistry and What Does a Periodontist Do?

Periodontics is a specialized field of dentistry focused on the surrounding and supporting structures of the teeth. This branch of oral health is dedicated to maintaining the health, function, and aesthetics of the tissues that anchor the teeth within the jawbone. Healthy gums and underlying bone provide the necessary foundation for a stable and functional smile. Deterioration of these structures can ultimately lead to tooth loss. A periodontist is the dental specialist uniquely trained to manage the complex needs of this foundational anatomy.

Defining the Field of Periodontics

Periodontics specifically studies the periodontium, the collective term for the tissues supporting the teeth. The periodontium consists of four main components: the gingiva (gums), the alveolar bone, the cementum, and the periodontal ligament. The alveolar bone forms the sockets that hold the teeth, while the cementum is the hard layer covering the tooth root. The periodontal ligament connects the cementum to the alveolar bone, acting as a shock absorber during chewing.

A periodontist specializes in the prevention, diagnosis, and treatment of diseases affecting these supporting structures. Beyond dental school, specialists complete an additional three years of intensive, advanced training. This postgraduate education focuses heavily on surgical techniques, advanced disease management, and the placement of dental implants.

Understanding Periodontal Disease

The primary focus of periodontics is treating periodontal disease, an inflammatory condition affecting the periodontium. The disease begins with gingivitis, the mildest form, involving inflammation caused by bacterial plaque accumulation. Gums affected by gingivitis often appear red, swollen, and may bleed easily during brushing or flossing. Since gingivitis does not involve the destruction of underlying bone or ligaments, it is reversible with professional cleaning and improved oral hygiene.

If untreated, the inflammation progresses to periodontitis, a more advanced and destructive stage. The bacterial infection spreads below the gumline, triggering a chronic inflammatory response that destroys the periodontal ligament and alveolar bone. This destruction leads to the formation of deep spaces known as periodontal pockets, which harbor more bacteria. Symptoms of periodontitis include persistent bad breath, receding gums, and teeth that become loose or shift positions. This bone loss is irreversible, making early diagnosis and specialized treatment necessary to halt further damage and prevent tooth loss.

Non-Surgical Treatment Approaches

The initial approach to managing early to moderate periodontitis involves non-surgical procedures aimed at controlling the bacterial infection. The most common treatment is Scaling and Root Planing, often called a “deep cleaning.” This specialized procedure targets plaque and hard calculus deposits located below the gumline and around the tooth roots, differing from a standard professional cleaning.

Scaling involves the careful removal of accumulated plaque and hardened calculus (tartar) from the tooth surface, extending into the periodontal pockets. Following scaling, the periodontist performs root planing, smoothing the rough surfaces of the tooth roots. This smoothing makes it difficult for bacteria to reattach, promoting the reattachment of gum tissue to the healthier root surface. Localized antibiotics or antimicrobial rinses may also be placed directly into the treated pockets to further reduce the bacterial load and aid in healing.

Advanced Surgical Procedures

When non-surgical treatments are insufficient for advanced periodontitis, or when significant tissue damage exists, surgical intervention may be recommended. Pocket reduction surgery (flap or osseous surgery) is a standard procedure used to treat deep periodontal pockets. During this procedure, the periodontist folds back the gum tissue to gain direct access to the deeper infection and bone. This allows for thorough removal of bacteria, calculus, and infected tissue, and may include reshaping the bone to eliminate irregular surfaces that trap bacteria.

Another common technique is gum grafting, used to cover exposed tooth roots caused by recession. Receding gums can lead to increased tooth sensitivity and vulnerability to decay. The periodontist harvests a small piece of tissue, often from the roof of the mouth or uses donor tissue, and attaches it to the area of recession. Periodontists also perform regenerative procedures, using bone grafts, membranes, or tissue-stimulating proteins to encourage the body to regrow bone and ligament tissue lost to the disease.

The Role of Dental Implants

Periodontists are highly skilled in the surgical placement and long-term management of dental implants, which serve as artificial tooth roots used to replace missing teeth. Their extensive training in managing the hard and soft tissues of the jaw makes them well-suited for this procedure. The success of an implant depends on the quality and quantity of the surrounding bone, a factor the periodontist assesses through detailed diagnostic imaging.

Patients often require preparatory procedures, such as bone grafting, to build up jawbone density before the implant can be securely placed. The periodontist surgically places the titanium implant into the jawbone, initiating osseointegration, where the bone fuses directly to the implant surface. Periodontists also manage complications that can arise after placement, such as peri-implant diseases—inflammatory conditions affecting the soft and hard tissues surrounding the implant. These infections, like peri-implant mucositis and peri-implantitis, must be treated promptly to prevent bone loss and potential implant failure.
