What Is a Periodontist? When You Need One and How to Find One

Editorially reviewed by the Dental.me Editorial Team · Updated July 2026

A periodontist is a dentist who specializes in the gums, the bone around your teeth, and dental implants. They spend about three extra years training after dental school so they can treat gum disease, place implants, and do surgery your regular dentist doesn’t touch. You usually land in one’s chair after a referral, once bleeding gums, loose teeth, or a failing implant push a case past what routine care can fix.

Most people never give their gums a second thought until a dentist says the word “pockets,” or “bone loss,” or rattles off a number like 5mm during a checkup. That’s usually the moment a periodontist enters the story. Your gums and jawbone are the foundation everything else sits on, and when the foundation starts to give, the periodontist is the specialist trained to stop the slide.

What does a periodontist actually do?

Picture your general dentist as the primary-care doctor of your mouth. The periodontist is the specialist you get sent to when the trouble is structural. Their attention goes to the supporting cast around your teeth: the gum tissue, the periodontal ligament, and the jawbone that keeps each root anchored.

The day-to-day work covers a specific set of problems:

• Gum disease at every stage, from early gingivitis that won’t clear up to advanced periodontitis that’s eating away at bone.
• Deep cleanings (scaling and root planing) that reach below the gumline, where a routine cleaning can’t go.
• Gum grafts to cover exposed roots and keep recession from getting worse.
• Dental implants, from surgically placing the post to rebuilding bone that isn’t thick enough to hold one.
• Crown lengthening and pocket-reduction surgery to reshape gum and bone.
• Loose-tooth treatment, including the tough call on whether a tooth can be saved or has to come out.

They also field the harder diagnostic questions: chronic bad breath that won’t quit, gums that bleed every time you floss, teeth that suddenly feel like they’ve shifted. A periodontist reads those signals against the health of the bone underneath, which only shows up on X-rays and by measuring pocket depths one tooth at a time.

How much training does a periodontist have?

Every periodontist starts out as a general dentist. After earning a DDS or DMD, they finish an accredited residency in periodontics that runs about three years. Count college and dental school and you’re looking at roughly 11 years of education in total.

During residency they perform hundreds of surgical procedures, learn advanced anesthesia, and study how gum health ties into the rest of the body. Diabetes, heart disease, and pregnancy all interact with the gums, and periodontists are trained to manage patients whose treatment gets complicated by those factors. Board-certified periodontists (Diplomates of the American Board of Periodontology) clear an extra round of exams on top of the residency.

That depth is the entire reason a referral exists. A general dentist can clean teeth and fill cavities all day long. Rebuilding a jawbone or grafting tissue is a different craft.

When do you need to see a periodontist?

Here’s the honest version: most people don’t need one, right up until they suddenly do. The trigger is almost always one of a handful of situations.

Your dentist referred you. This is the most common route by far. If your hygienist starts calling out pocket depths of 4mm or more, or your dentist spots bone loss on an X-ray, a referral follows. Take it seriously. Early periodontitis is far cheaper and a lot less painful to treat than the advanced kind.

Your gums bleed constantly. A little pink when you floss after skipping a few weeks is one thing. Gums that bleed every single time, or that stay red and puffy no matter how carefully you brush, point to active inflammation.

You have receding gums or “long” teeth. Recession exposes the root, causes sensitivity, and doesn’t reverse on its own. A graft can cover it and protect the tooth.

A tooth feels loose. Adult teeth should not move. Period. Mobility usually means the bone anchoring that tooth is disappearing, and that needs a specialist’s eyes on it fast.

You want dental implants. Plenty of general dentists place implants these days, but complex cases, thin bone, or multiple implants are squarely periodontist territory. They also handle bone grafting and sinus lifts to make an implant possible when there isn’t enough bone to work with.

You have a health condition that raises your risk. Diabetes, a heart condition, or a family history of gum disease can all justify having a periodontist keep an eye on you before symptoms ever flare.

Periodontist vs. general dentist vs. other specialists

The specialty names blur together for most patients. This table sorts out who does what.

Periodontists and oral surgeons overlap on implants, which trips up a lot of patients. The short version: oral surgeons lean toward surgical extraction and the jaw, periodontists toward the gum and bone that surround and support the implant. For a straightforward single implant, either one can do excellent work. For a case tangled up with gum disease, a periodontist is often the better fit, because they treat the underlying problem instead of just installing the hardware.

What does periodontal treatment cost?

Costs swing widely by procedure, region, and how far the problem has progressed. The figures below are typical US ranges, not our directory data, and they’re before insurance. A lot of dental plans cover a meaningful chunk of periodontal work because it counts as medically necessary rather than cosmetic, so your out-of-pocket number often comes in below the sticker.

A few things push the number around. Geography matters a lot; the same graft runs higher in a major coastal metro than in a smaller market. The number of quadrants or sites treated multiplies the total. And bone grafting alongside an implant can tack on a thousand dollars or more. Always ask for a written treatment plan with itemized codes so you can run it past your insurer before you commit to anything.

What happens at your first periodontist visit?

The first appointment is mostly detective work. Expect full periodontal charting, where the provider measures the pocket depth around each tooth with a small probe and writes down every number. You’ll likely get X-rays to show the bone level, plus a review of your medical history, your medications, and habits like smoking that drag on gum health.

From there you get a staged plan. Mild cases often start with a deep cleaning and a tighter recall schedule, no surgery involved. More advanced cases move toward grafting or surgical pocket reduction. A good periodontist walks you through the non-surgical options first and explains, in plain terms, exactly why surgery is or isn’t on the table.

How to find a good periodontist near you

Start with your general dentist’s referral, then do your own homework instead of just booking the first name you’re handed. A few filters worth applying:

• Confirm the credential. Look for an actual periodontist, ideally board-certified by the American Board of Periodontology, not a general dentist who lists gum treatment as one service among many.
• Read recent reviews for specifics. Comments about clear explanations, a gentle touch, and honest treatment plans tell you more than a raw star count.
• Ask about their implant volume if that’s why you’re going. Experience compounds in surgery.
• Check that they take your insurance and will submit a pre-authorization before any major work.

You can compare local periodontists on Dental.me’s specialty directory, which lists gum and implant specialists next to our independent Dental.me Score so you’re not judging on marketing alone. If you’re just starting the search, the dentist near me tool narrows results to your area, and state hubs like our Texas directory break it down city by city.

Frequently asked questions

Is a periodontist the same as a dentist?

Every periodontist is a dentist first, then completes about three extra years of specialty training in gums, bone, and implants. So they’re a dentist with a narrower, deeper focus, not a separate profession.

Can I go to a periodontist without a referral?

In most cases yes, you can book directly. But some insurance plans require a referral from your general dentist to cover the visit, so check your plan first.

Does insurance cover periodontal treatment?

Often, at least partially. Because gum disease treatment is medically necessary rather than cosmetic, many dental and some medical plans cover deep cleanings, grafts, and related surgery. Get a pre-authorization to see your exact share.

Can a periodontist save a loose tooth?

Sometimes. If enough bone remains, treatments like deep cleaning, splinting, or bone grafting can stabilize a loose tooth. If too much support is gone, the periodontist will tell you honestly whether extraction and an implant is the better path.

What’s the difference between a periodontist and an oral surgeon for implants?

Both place implants. Periodontists specialize in the gum and bone around the implant and in treating any underlying gum disease, while oral surgeons focus on surgical extractions and jaw work. For cases involving gum disease, a periodontist is often the stronger choice.

How do I know if my gum disease is serious?

Pocket depths of 4mm are an early warning sign; 5 to 6mm is moderate, and 7mm or deeper, especially alongside visible bone loss, receding gums, or loose teeth, points to advanced disease. Only periodontal charting during an exam can grade it accurately.

This article is general information, not dental advice. Gum disease is graded by exam, and a periodontist’s in-person evaluation is the only accurate way to assess your case.
