A periodontist is a dentist who specializes in the prevention, diagnosis, and treatment of gum disease, along with the surgical placement of dental implants. While your general dentist handles routine cleanings and fillings, a periodontist focuses specifically on the structures that support your teeth: gums, bone, and the connective tissues that hold everything in place. Within dentistry, they’re considered the experts in both hard tissue (teeth and bone) and soft tissue (gums, cheeks, and the lining of the mouth).
How Periodontists Differ From General Dentists
Every periodontist starts with a four-year dental degree, then completes an additional three-year residency focused entirely on gum surgery, bone grafting, tissue regeneration, and implant placement. That extra training matters because gum disease operates below the surface, in areas a general dentist isn’t always equipped to manage surgically. General dentists handle the bulk of preventive care and can treat early-stage gum problems, but they typically refer patients to a periodontist when the disease has progressed or when surgical intervention is needed.
Referrals often happen when probing reveals deep pockets between the gums and teeth. Healthy gums sit snugly against the tooth with pocket depths of 1 to 3 millimeters. Once pockets reach 6 millimeters or more, especially alongside significant bone loss, that’s the threshold where specialist care becomes important. At that depth, bacteria colonize areas that standard cleanings can’t reach, and the risk of losing teeth climbs sharply.
Deep Cleaning: Scaling and Root Planing
The most common procedure periodontists perform is scaling and root planing, often called a “deep cleaning.” It’s similar to a regular dental cleaning but goes significantly further beneath the gum line. After numbing the area with local anesthesia, your periodontist or hygienist uses hand instruments or ultrasonic tools to remove plaque and tartar from both above and below the gums. The root planing step smooths the tooth roots, which helps the gum tissue reattach and makes it harder for bacteria to cling to rough surfaces in the future.
For many patients with moderate gum disease, this non-surgical treatment is the first line of defense. It can halt the progression of bone loss and significantly reduce pocket depths when followed by consistent home care and regular maintenance visits.
Gum Surgery and Tissue Regeneration
When deep cleaning alone isn’t enough, periodontists turn to surgical options. These range from pocket reduction surgery, where gum tissue is folded back so bacteria and damaged bone can be cleaned out directly, to regenerative procedures that aim to rebuild bone and tissue that gum disease has destroyed.
One increasingly common approach is laser-assisted surgery. The FDA-cleared LANAP protocol uses a specialized laser to selectively remove diseased tissue while leaving healthy tissue intact. The laser energy kills bacteria, seals the pocket with a blood clot that acts as a natural barrier, and stimulates the body’s own stem cells to regenerate bone and connective tissue. Compared to traditional surgery with a scalpel, laser treatment typically causes less pain afterward, less gum recession, reduced sensitivity, and faster healing. The FDA specifically cleared this technology for true regeneration of the bone, root surface coating, and connective tissue needed for full tooth support, not just repair.
Periodontists also perform soft tissue grafts for people with receding gums. This involves taking a small amount of tissue, often from the roof of the mouth, and attaching it where gums have pulled away from the tooth. The goal is to cover exposed roots, reduce sensitivity, and prevent further recession.
Dental Implant Placement
Periodontists are among the most qualified specialists to place dental implants because they understand both the bone and the gum tissue that surrounds them. The process involves surgically inserting a titanium post into the jawbone to replace a missing tooth root. Over several months, the bone fuses with the implant, creating a stable anchor for a crown, bridge, or denture.
What sets periodontists apart in implant dentistry is their ability to handle complications before they arise. If your jawbone has thinned from years of missing teeth or bone loss, a periodontist can perform bone grafting to rebuild the foundation. For upper back teeth, where the sinus cavity sits close to the jaw, a sinus lift procedure adds bone material to create enough depth for the implant. They also reshape gum tissue around the implant so it looks natural and stays easy to clean. Planning the exact position of each implant for both function and appearance is a core part of what they do.
Long-Term Results of Periodontal Treatment
Specialist treatment produces strong long-term outcomes. A large study tracking 687 patients and nearly 16,000 teeth over an average of about seven years found that 96% of teeth survived. More than half of those patients, 56%, didn’t lose a single tooth during that period, and another 22% lost only one. This is notable because over 60% of the patients in the study had severe periodontitis at the start.
The data also revealed clear patterns about which teeth are most at risk. Canines had the highest eight-year survival rate at 98.3%, followed by incisors at 97.6%, premolars at 96.3%, and molars at 93.8%. Molars are harder to save because their multiple roots create fork-like junctions where bacteria can hide. When those junctions are severely involved, the survival rate drops to around 44% over eight years. Teeth with persistent deep pockets of 6 millimeters or more after treatment were nearly seven times more likely to be lost than teeth with shallow pockets, which underscores why ongoing maintenance visits matter so much.
What Recovery Looks Like
Recovery depends on the procedure. After scaling and root planing, most people experience some gum tenderness and sensitivity for a few days, but normal activities can resume almost immediately. Surgical procedures require more patience.
In the first day or two after gum surgery, expect some bleeding, swelling, and discomfort. Your body’s immune response kicks in quickly, sending white blood cells to the surgical site to clear debris and fight infection. Over the following one to two weeks, new tissue starts forming to replace what was removed, and blood vessels grow into the area to deliver oxygen and nutrients. The wound gradually closes as cells fill in the gaps, and you may notice pinkish or white granular tissue forming, which is a healthy sign. Full maturation of the tissue takes several weeks to months, as collagen fibers reorganize and strengthen the area.
During recovery, you’ll want to stick to soft foods, avoid anything hot or crunchy near the surgical site, and be gentle with brushing. Follow-up visits in the weeks after surgery let your periodontist check that healing is on track and catch any problems early.
Ongoing Maintenance
Gum disease is a chronic condition. Even after successful treatment, the bacteria that cause it never fully disappear from your mouth. Periodontists typically recommend maintenance cleanings every three to four months rather than the standard six-month schedule. These visits involve measuring pocket depths, cleaning below the gum line, and catching any signs of relapse before they lead to more bone loss. The long-term success rates in research studies reflect patients who stuck with this kind of regular follow-up, and skipping it is one of the biggest risk factors for losing the gains treatment provided.
