Dentistry recognizes 12 specialties. Two of them — prosthodontics and periodontics — are often confused with each other, particularly in the context of dental implants. Both specialists handle implants. Neither one does the same job. If you're being referred to one of them or trying to decide which to consult, the distinction matters.
This page is a straightforward explanation of what each specialty trains for, what each one does in practice, and how to figure out which one (or both) belongs on your treatment plan.
What a prosthodontist does
A prosthodontist is a dentist who has completed 3 additional years of accredited residency training after dental school, focused on the replacement and restoration of teeth. The specialty exists at the intersection of dentistry, materials science, and applied biomechanics — because rebuilding a functioning bite involves all three.
The prosthodontist's clinical territory:
- Crowns and bridges — both single-tooth and multi-unit
- Dental implants — surgical placement and, more critically, the prosthetic planning that determines the implant's position, angle, and final restoration
- Full-arch implant treatment (sometimes called "All-on-4" or "All-on-X")
- Dentures and overdentures — including implant-retained dentures
- Veneers and aesthetic restorations
- TMJ disorders and bite reconstruction
- Maxillofacial prosthetics — restorations following oral cancer surgery, trauma, or congenital absence
The defining feature of prosthodontics is planning the case from the final tooth backwards. A prosthodontist designs the end-state restoration first — what teeth the patient will actually chew with — and then works backwards to determine where the implants need to go, how much bone needs to be there, what the bite needs to look like, and what materials will hold up.
To use the title "Prosthodontist," a dentist must be recognized by the American Dental Association in the specialty, which requires completion of a CODA-accredited prosthodontic residency program.
What a periodontist does
A periodontist is a dentist who has completed 3 additional years of accredited residency training after dental school, focused on the supporting structures of teeth — the gums and the bone beneath them.
The periodontist's clinical territory:
- Gum disease — diagnosis and surgical/non-surgical treatment of periodontitis
- Gum surgery — including grafts, crown-lengthening, and gingival recontouring
- Bone grafting — particularly around teeth and at implant sites
- Dental implant surgery — placement of the implant itself
- Soft-tissue grafting — for receding gums or thin tissue around implants
- Maintenance of patients with chronic periodontal disease
The defining feature of periodontics is the health of the foundation that holds teeth (or implants) in place. When the foundation is failing, the periodontist is the right specialist.
Where the two overlap (and where they don't)
Both prosthodontists and periodontists place dental implants. This is the source of most patient confusion, and it's a fair confusion to have.
The simplest framing: the periodontist places the implant, and the prosthodontist designs the case and restores the implant. In practice, prosthodontists also place implants — especially in cases where the surgical position is dictated tightly by the prosthetic plan — and periodontists also restore implants in some practices. But the disciplines bring different default emphases to the case:
- A periodontist's instinct is to optimize for the surgical site: bone volume, soft-tissue health, infection control.
- A prosthodontist's instinct is to optimize for the final restoration: where the tooth needs to be, what bite force it has to absorb, what the smile is going to look like in 20 years.
For straightforward single-tooth implants in a healthy mouth, either specialist can deliver an excellent result. For complex cases — full-arch reconstructions, failed previous implants, severe bite problems, aesthetic-zone cases, patients who've been told "no" elsewhere — the prosthodontic planning lens tends to drive better long-term outcomes because the implant decisions are forced to serve the restoration.
Which specialist do you actually need?
A rough guide:
See a periodontist when:
- You have active gum disease that needs surgical treatment
- Your gums have receded significantly and you need a gum graft
- You're losing bone around natural teeth and need it stabilized
- You need an implant placed in a healthy mouth and the restoring dentist will handle the prosthetic side
See a prosthodontist when:
- You're considering full-arch implant treatment ("All-on-4" or similar)
- You have multiple missing teeth and aren't sure what restoration is right
- A previous implant has failed or is failing
- You've been told elsewhere that your case is "too complex"
- You want a single dentist responsible for the whole plan — surgery and restoration alike
- You have TMJ pain, an unbalanced bite, or significant wear
You may need both when:
- You have advanced periodontal disease and need extensive implant treatment
- The case involves significant bone or soft-tissue reconstruction in addition to complex prosthetic planning
There's no rule against consulting both — in fact, for complex cases, having the prosthodontist plan the case and a periodontist execute the surgical portion is a common and effective collaboration.
A note on general dentists who place implants
A growing number of general dentists place and restore implants without specialty training. For routine cases, many do this well. The risk shows up in the cases that look routine but aren't: thin biotype, sinus proximity, parafunctional habits, aesthetic-zone placement, or anything outside the standard playbook. Those are the cases where specialty training matters, and they're often not identifiable as "complex" until something goes wrong.
If you're considering an implant from a general dentist, two reasonable questions to ask: How many implants do you place per year? and What does the case plan look like in 20 years if I bite hard on this tooth every day?
Frequently asked questions
Is a prosthodontist more expensive than a periodontist?
Fees vary by case, geography, and practice. The two specialties cost roughly the same for comparable procedures. Specialist care often costs more than general dentistry but tends to be a single-payment-for-a-finished-case rather than the cumulative cost of redoing work.
Can a prosthodontist treat gum disease?
Prosthodontists treat the gum component of cases they're managing, but for active periodontal disease the right specialist is a periodontist.
Do I need a referral?
No. You can self-refer to either specialist in Hawaii.
Is "implant specialist" the same as a prosthodontist or periodontist?
"Implant specialist" is not an ADA-recognized specialty. The recognized specialties involved in implant care are prosthodontics, periodontics, and oral and maxillofacial surgery. Be cautious of the term "specialist" when it's not paired with one of the recognized specialty titles.
When in doubt, start with the plan
If you don't know which specialist you need, start with whichever one will treat your case as a whole rather than as a procedure. For implant cases especially, the plan drives everything — and the plan is where prosthodontics is built to start.
