Periodontics is the branch of dentistry focused on the structures that support your teeth, primarily the gums and the underlying bone. Periodontists diagnose, treat, and prevent gum disease and also place dental implants. About 42% of American adults over 30 have some form of periodontal disease, making this one of the most commonly needed dental specialties.
What Periodontics Covers
The word “periodontics” comes from the Greek words for “around” (peri) and “tooth” (odont). The specialty deals with everything surrounding and anchoring teeth in place: gum tissue, the bone of the jaw, and the ligaments connecting teeth to bone. When any of these structures become infected or break down, a periodontist steps in.
The field covers two broad areas. The first is gum disease in all its stages, from mild inflammation (gingivitis) to advanced bone loss that causes teeth to loosen and fall out. The second is dental implants, the titanium posts surgically placed into the jawbone to replace missing teeth. Because periodontists spend years training on both bone and soft tissue, they handle the surgical side of implant placement.
How Periodontists Differ From General Dentists
Every periodontist is a dentist, but not every dentist is a periodontist. After completing four years of dental school, periodontists go through an additional two to three years of specialized residency training. That residency focuses intensively on gum tissue management, bone regeneration, surgical techniques, sedation, and microsurgery. A general dentist can treat early gum disease, but more complex cases, including surgery and implants, typically call for a periodontist’s training.
The Four Stages of Gum Disease
Periodontists use a staging system to classify how far gum disease has progressed. This system looks at how much tissue and bone has been lost, how deep the pockets around your teeth have become, and whether you’ve lost any teeth as a result.
- Stage I (initial): Slight loss of attachment between tooth and gum, with pocket depths of 4 mm or less. No teeth lost. Bone loss is minimal, affecting less than 15% of the root area.
- Stage II (moderate): Pocket depths up to 5 mm, with bone loss reaching up to a third of the root. Still no teeth lost, but more tissue damage is visible on X-rays.
- Stage III (severe): Pockets 6 mm or deeper, with bone loss extending past the middle of the root. Up to four teeth may have been lost to the disease. The bone may start breaking down vertically rather than evenly, creating deeper defects.
- Stage IV (advanced): Five or more teeth lost to gum disease, with fewer than 20 teeth remaining. Teeth may drift, loosen, or shift your bite. Complex rehabilitation is needed to restore normal chewing function.
Signs That Point to Gum Disease
Gum disease often progresses without obvious pain, which is part of what makes it so common. The signs to watch for include gums that are red, swollen, tender, or bleed when you brush or floss. Gums that have pulled away from the teeth, making teeth look longer than usual, are another classic warning sign. Persistent bad breath that doesn’t go away with brushing, loose teeth, pain while chewing, and increased sensitivity can all indicate that the supporting structures around your teeth are breaking down.
Common Periodontal Treatments
The most common starting treatment is a deep cleaning called scaling and root planing. Scaling removes plaque and hardite buildup (tartar) both above and below the gumline using hand instruments or ultrasonic tools. Root planing then smooths the surfaces of your tooth roots so bacteria have a harder time reattaching. Antibiotics may be placed directly around the roots or prescribed to take afterward. For many people with Stage I or Stage II disease, this nonsurgical approach is enough to halt progression.
When gum disease has caused significant damage, surgical options come into play. Gum graft surgery is one of the most common. During the procedure, a periodontist takes tissue from the roof of your mouth (or uses a substitute material from a tissue bank) and attaches it to areas where gums have receded. This protects exposed roots and can improve the appearance of your smile. Bone regeneration procedures use grafting materials to rebuild jawbone that has been destroyed by infection. Periodontists also perform pocket reduction surgery, folding back the gum tissue to remove bacteria from deep pockets and then securing the tissue more snugly around the tooth.
Why Gum Health Affects the Rest of Your Body
Periodontal disease doesn’t stay in your mouth. The chronic inflammation and bacteria involved have been linked to a surprisingly wide list of systemic health problems. A landmark Surgeon General’s report in 2000 recognized associations between gum disease and cardiovascular disease, stroke, diabetes, and adverse pregnancy outcomes. Research since then has expanded that list to include Alzheimer’s disease and dementia, rheumatoid arthritis, obesity, chronic kidney disease, and several types of cancer.
The relationship often goes both ways. Diabetes, for example, makes gum disease worse by impairing the body’s ability to fight infection, while the inflammation from gum disease can make blood sugar harder to control. Conditions like osteoporosis can weaken the jawbone, accelerating the damage periodontal disease causes. This two-way connection is a major reason periodontists often coordinate care with other medical providers.
What a Periodontist Visit Looks Like
Your general dentist may refer you to a periodontist, or you can schedule a visit on your own. During a first appointment, the periodontist will measure the depth of the pockets around each tooth using a small probe. Healthy pockets are typically 1 to 3 mm deep. Anything beyond that suggests tissue attachment has been lost. X-rays show how much bone remains around the roots. Together, these measurements determine the stage of disease and guide the treatment plan.
Follow-up visits depend on severity. Mild cases may only need deep cleanings every few months. Surgical cases require a healing period, often several weeks, with periodic check-ins to make sure the tissue is recovering properly. Most people with a history of gum disease will need more frequent maintenance visits, typically every three to four months rather than the standard six-month cleaning schedule, to keep bacteria from building up again.
