Periodontics is the branch of dentistry focused on the health of your gums, jawbone, and the other tissues that hold your teeth in place. The name comes from two Greek words: “peri” (around) and “odont” (tooth). If you’ve heard the term at a dental office or seen it on a referral, it simply means a specialist area dedicated to preventing, diagnosing, and treating conditions that affect the foundation your teeth sit in.
What Periodontics Actually Covers
Your teeth don’t just float in your mouth. They’re anchored by a system of tissues called the periodontium, and periodontics is the specialty that cares for all of them. That includes your gums, the connective tissue fibers that attach each tooth to the jawbone, the hard coating over your tooth roots, and the section of jawbone that contains your tooth sockets. When any of these structures become damaged or diseased, a periodontist steps in.
The most common reason people encounter periodontics is gum disease, also called periodontal disease. But the specialty also covers dental implant placement, bone grafting, gum recession treatment, and regenerative procedures that rebuild tissue you’ve already lost.
How Gum Disease Is Classified
Periodontists classify gum disease using a staging system that ranges from Stage I through Stage IV, based on how much tissue has been destroyed and how complex the case is to manage. At Stage I, there’s mild damage. By Stage IV, there’s extensive bone loss and teeth may have already been lost. Your dentist measures the depth of the pockets between your gums and teeth to help determine this: 1 to 3 millimeters is normal, 4 to 5 millimeters signals early gum disease, 5 to 7 millimeters is moderate, and anything from 7 to 12 millimeters is advanced.
On top of staging, periodontists also assign a grade (A, B, or C) that reflects how quickly the disease is progressing. Grade A means slow progression with no measurable bone loss over five years. Grade B is moderate, with less than 2 millimeters of loss over five years. Grade C is rapid, with 2 or more millimeters lost in that same window. Someone with Grade C disease may see significant damage even with relatively little plaque buildup, which points to a stronger underlying susceptibility.
Common Periodontal Treatments
The first line of treatment for mild to moderate gum disease is scaling and root planing, often called a “deep cleaning.” It’s similar to a standard dental cleaning but reaches further beneath the gumline. After numbing your gums with local anesthesia, your provider uses hand instruments or ultrasonic tools to scrape away plaque and tartar from your teeth above and below the gums. They then smooth the tooth roots, which helps your gums reattach and makes it harder for bacteria to take hold again. Antibiotics may be placed around the roots or prescribed afterward.
Since a regular toothbrush can’t clean effectively below about 3 millimeters, pockets deeper than 5 millimeters usually need more aggressive treatment. That can mean surgical procedures like flap surgery, where the gums are lifted back so deeper deposits can be removed and the bone reshaped. In cases of significant bone loss, grafting procedures use material (from your own body, a donor, animal sources, or synthetic alternatives) to rebuild the jawbone and create a solid foundation again.
Dental Implants and Bone Grafting
Periodontists play a major role in dental implant treatment. Their training in bone health and gum tissue makes them well suited to surgically place implants and manage the surrounding tissues for long-term success. They handle everything from single-tooth replacements to full-arch solutions, planning each implant’s position for both function and appearance.
When the jawbone is too thin or too low to support an implant, a periodontist can perform bone grafting or a procedure called a sinus lift to build up the area first. This extra step allows the implant to integrate properly with the bone and last longer. If an implant later develops infection or bone loss, a condition called peri-implantitis, a periodontist treats it with cleaning, surgery, antibiotics, or regenerative techniques to save the implant when possible.
How Tissue Regeneration Works
One of the more advanced areas of periodontics is regenerating tissue that gum disease has destroyed. A technique called guided tissue regeneration uses a thin membrane as a physical barrier over the damaged area. This barrier prevents faster-growing gum tissue from filling in the space and instead gives bone and connective tissue time to regrow where it’s needed. These membranes come in two types: resorbable ones (usually made from collagen) that dissolve on their own, and non-resorbable ones that require a second procedure for removal.
Bone grafts are frequently paired with these membranes. Grafts taken from your own body are considered the gold standard because they have all the biological properties needed to stimulate new growth. But donor bone, animal-derived bone, and synthetic materials are all widely used alternatives, each with specific advantages depending on the size and location of the defect.
The Link Between Gum Disease and Overall Health
Periodontics matters beyond your mouth. Gum disease and diabetes have a well-documented two-way relationship: poorly controlled diabetes increases the risk, severity, and speed of gum disease, while gum disease makes it harder to control blood sugar. Clinical trials show that treating gum disease can reduce HbA1c (a key marker of blood sugar control) by about 0.43%, which is a meaningful improvement. A meta-analysis of 10 studies found that people with gum disease had a 26% higher risk of developing diabetes in the first place.
The connection runs through inflammation. Bacteria from infected gums can enter the bloodstream, triggering a low-grade immune response throughout the body. Inflammatory molecules produced during this process can interfere with insulin signaling, promote insulin resistance, and even damage the cells in the pancreas that produce insulin. Researchers have also identified a pathway where harmful oral bacteria travel to the gut, either through the bloodstream or by being swallowed, and disrupt the gut microbiome in ways linked to cardiometabolic disease.
What a Periodontist’s Training Looks Like
A periodontist is a dentist who completed dental school and then went on to a three-year residency program specifically in periodontics. During that residency, they train in gum surgery, bone grafting, implant placement, and the management of complex periodontal conditions. Some programs offer the option of earning a master’s degree at the same time. This additional training is what distinguishes a periodontist from a general dentist, who may handle early gum disease but typically refers more advanced cases to a specialist.
Signs You May Need a Periodontist
Your general dentist measures your gum pocket depths at routine checkups. If those measurements start hitting 4 millimeters or above, gum disease is likely present. Pockets of 5 millimeters or deeper usually can’t be managed with regular cleanings alone and often warrant a referral. Other signs include gums that bleed easily, persistent bad breath, gum recession that exposes tooth roots, loose teeth, or changes in how your bite fits together. If you’ve been told you have bone loss but the tooth can still be saved, that’s a classic scenario for a periodontist’s involvement.
