A periodontist is a dentist who specializes in the gums, jawbone, and other tissues that hold your teeth in place. While your general dentist handles cleanings, fillings, and crowns, a periodontist steps in when the supporting structures around your teeth need deeper care. That includes treating gum disease, placing dental implants, and performing surgery to rebuild lost bone or tissue.
Training Beyond Dental School
Every periodontist completes four years of dental school, then goes on to a three-year residency focused entirely on the tissues surrounding your teeth. That extra training covers advanced surgical techniques, bone grafting, implant placement, and managing complex gum conditions. It’s what separates a periodontist from a general dentist: years of additional hands-on experience with the specific structures that support your teeth.
The Tissues a Periodontist Treats
Your teeth don’t just sit in your jaw on their own. They’re anchored by a system of tissues collectively called the periodontium, and each part plays a role in keeping teeth stable. A periodontist focuses on four key structures: your gums, the connective tissue fibers that attach teeth to bone, the hard coating over tooth roots, and the section of jawbone that contains the tooth sockets. When any of these break down, whether from infection, injury, or genetics, a periodontist is the specialist trained to intervene.
Non-Surgical Treatments
Not everything a periodontist does involves surgery. The most common starting point for gum disease treatment is a deep cleaning called scaling and root planing. During scaling, the periodontist works beneath the gumline to remove plaque, tartar, and bacterial toxins that have built up in the pockets around your teeth. Root planing follows: the tooth root surfaces are smoothed so bacteria have a harder time reattaching. For many patients with early to moderate gum disease, this is enough to halt the progression.
Laser treatment is another non-surgical option. Some periodontists use specific laser wavelengths to target infected tissue and bacteria in periodontal pockets. Studies show results comparable to scaling and root planing alone, though the choice of laser and settings matters. In some cases, periodontists also prescribe custom-fit trays that let you deliver medication directly to your gums at home, though the evidence behind specific tray-delivered medications is still limited.
Surgical Procedures
When gum disease has advanced far enough to create deep pockets around your teeth, surgery often becomes necessary. In a healthy mouth, the space between your gum and tooth measures 1 to 3 millimeters. Pockets deeper than 4 millimeters suggest periodontitis, and anything beyond 5 millimeters can’t be cleaned effectively with routine care. That’s typically when your dentist refers you to a periodontist.
One of the most common surgeries is pocket reduction (also called osseous surgery). The periodontist folds back the gum tissue, removes bacteria hiding deep in the pockets, and reshapes the underlying bone to eliminate the crevices where bacteria thrive. If significant bone has been lost, they may place bone grafts or membranes to encourage the jaw to regenerate.
Gum graft surgery addresses the opposite problem: when gums have receded and exposed the tooth roots. The periodontist takes tissue, often from the roof of your mouth, and attaches it over the exposed area. Recovery takes one to two weeks on average, and most people return to work or school within a day or two. You’ll eat soft, cool foods at first and gradually reintroduce solid foods over the second week. Brushing and flossing near the graft site is off-limits until the surgeon clears you, and strenuous exercise should wait at least a week.
A newer option for moderate to severe gum disease is a laser-based surgical protocol that uses targeted laser energy instead of a scalpel. One FDA-cleared approach has shown the ability to regenerate the connective tissue attachment between the tooth root and surrounding structures. In a controlled study, 100 percent of laser-treated teeth developed new connective tissue attachment after three months, while teeth treated with deep cleaning alone showed essentially none. It’s now considered a legitimate alternative to conventional flap surgery for appropriate candidates.
Dental Implant Placement
Periodontists are among the most qualified specialists to place dental implants, thanks to their deep understanding of bone and gum tissue. They plan the exact implant position to support both function and appearance, and they handle the preparatory work when your jaw isn’t ready for an implant on its own. If your bone is too thin or has lost volume, a periodontist can perform bone grafting or a sinus lift to build up enough support for the implant to integrate properly and last.
The relationship doesn’t end after placement. If an implant later develops infection or bone loss around it (a condition called peri-implantitis), a periodontist treats it with cleaning, surgery, antibiotics, or regenerative procedures to try to save the implant.
Gum Disease and Your Overall Health
Part of what a periodontist monitors goes beyond your mouth. Gum disease has well-documented links to several serious health conditions, and a periodontist considers these connections when managing your care.
The relationship between gum disease and diabetes runs in both directions. People with diabetes are more susceptible to infections, making them more likely to develop periodontal disease. At the same time, active gum disease can make blood sugar harder to control, increasing the risk of diabetic complications. Several studies also connect periodontal disease to a higher risk of heart disease, likely driven by the chronic inflammation that gum infections produce. For patients with certain heart conditions, antibiotics before dental procedures may be necessary.
The links extend further. Bacteria from infected gums can be inhaled into the lungs and contribute to respiratory infections like pneumonia. Research has found that men with gum disease were 49 percent more likely to develop kidney cancer, 54 percent more likely to develop pancreatic cancer, and 30 percent more likely to develop blood cancers. Studies have also found connections between gum disease bacteria and the progression of Alzheimer’s disease, with oral bacteria potentially traveling to the brain.
None of this means gum disease directly causes these conditions, but the associations are strong enough that managing periodontal health is increasingly seen as part of managing overall health. A periodontist is trained to understand these systemic links and factor them into treatment decisions.
How You End Up at a Periodontist
Most people see a periodontist through a referral from their general dentist. During a routine exam, your dentist measures the pocket depth around each tooth with a small probe. If those pockets consistently measure above 4 or 5 millimeters, or if you have signs of bone loss on X-rays, they’ll likely send you to a specialist. You might also be referred if you have receding gums, loose teeth, or gum disease that hasn’t responded to standard treatment.
Some people seek out a periodontist directly, particularly for dental implants or cosmetic gum procedures. You don’t always need a referral, though your insurance may require one for coverage purposes. If you have diabetes, a family history of gum disease, or have noticed persistent bleeding, swelling, or gum recession, a periodontist can assess whether the supporting structures around your teeth need attention your general dentist isn’t equipped to provide.
