A prosthodontist is a dentist who specializes in replacing and restoring teeth. They complete three additional years of training beyond dental school, focusing specifically on crowns, bridges, dentures, dental implants, and the reconstruction of damaged or missing teeth. Prosthodontics is one of 12 dental specialties recognized by the American Dental Association.
What Prosthodontists Do
The core of a prosthodontist’s work centers on replacing missing teeth and repairing badly damaged ones. While a general dentist handles routine care like fillings and cleanings, a prosthodontist focuses on more complex restorations that involve rebuilding your bite, replacing multiple teeth, or restoring oral function after injury or disease.
The most common treatments they provide include:
- Dental implants: Small threaded posts made from surgical-grade titanium or ceramic, placed into your jawbone to replace missing tooth roots. Once healed, the prosthodontist restores them with crowns, bridges, or dentures.
- Crowns: Custom caps that cover a badly damaged tooth, often needed after extensive decay, a crack, or a root canal.
- Bridges: Prosthetics that replace one or more missing teeth in a row, anchored by crowns on the teeth on either side.
- Dentures: Partial dentures replace several missing teeth scattered across your mouth, while full dentures replace an entire arch.
- Inlays and onlays: Custom restorations for teeth too damaged for a filling but not damaged enough for a full crown. They fit into the tooth structure like small puzzle pieces.
- Oral splints and night guards: Devices used to manage TMJ disorders and sleep apnea.
How Their Training Differs From a General Dentist
Every prosthodontist first earns a dental degree, just like a general dentist. The difference is what comes next: a 36-month residency in an accredited prosthodontic program. During that residency, they train across four phases of the specialty: removable prosthetics, fixed prosthetics, implants, and maxillofacial reconstruction. They also get interdisciplinary exposure to oral surgery, root canal treatment, and gum disease management.
General dentists are trained to handle routine care and minor procedures. Prosthodontists are trained to handle complex cases that involve multiple missing teeth, jaw alignment problems, or full mouth rehabilitation. Think of the distinction like the one between a family doctor and a surgeon. Both are fully licensed, but one has additional years of focused training for more complicated situations.
After residency, prosthodontists can pursue board certification through the American Board of Prosthodontics. This involves written and oral examinations that test knowledge, clinical skill, and proficiency. Those who pass earn the title of Diplomate, which signals an additional level of verified expertise.
Full Mouth Reconstruction
One of the more involved procedures prosthodontists handle is full mouth reconstruction, sometimes called full mouth rehabilitation. This is exactly what it sounds like: a comprehensive plan to restore or replace most or all of the teeth in your mouth. It often combines implants, crowns, bridges, and sometimes dentures into a single coordinated treatment plan.
Full mouth reconstruction improves chewing ability, changes appearance, and can significantly improve quality of life. These cases typically involve a team approach, with prosthodontists working alongside oral surgeons and other specialists. The prosthodontist generally serves as the architect of the plan, determining how all the pieces fit together so your bite functions properly.
Maxillofacial Prosthetics
Some prosthodontists subspecialize in maxillofacial prosthetics, which involves restoring parts of the face and mouth lost to cancer surgery, trauma, or birth defects. These specialists create prosthetic devices that help patients speak, swallow, and chew after losing portions of the jaw, palate, or facial tissue.
For head and neck cancer patients specifically, maxillofacial prosthodontists play a dual role. They design removable prostheses that restore function, and those same prostheses offer an important secondary benefit: they allow direct visualization of the surgical site, making it easier to monitor for cancer recurrence during the critical first three years of follow-up. When surgery is being planned, the prosthodontist ideally consults beforehand to assess the patient’s capacity for functional rehabilitation and help shape the surgical approach.
Technology in Modern Prosthodontics
Prosthodontics has become one of the more technology-driven dental specialties. Computer-aided design and manufacturing (CAD/CAM) first entered the field in the 1980s and has since become the standard method for fabricating many types of restorations. This technology enables precise creation of prostheses from advanced materials like zirconia ceramics that couldn’t reliably be shaped by hand.
Today’s workflow often starts with a digital scan of your mouth rather than the traditional putty impression. Intraoral scanners capture a detailed 3D model of your teeth and gums, which feeds into design software where the prosthodontist plans the restoration digitally before anything is manufactured. Some practices now combine these scans with 3D radiographic imaging to create a “virtual dental patient,” a complete digital replica that allows treatment to be simulated before any physical work begins. Artificial intelligence is also beginning to assist with tasks like outlining margins and designing how your teeth will come together when you bite.
When You Might Be Referred to One
Your general dentist can handle a single crown or a straightforward bridge. You’re more likely to be referred to a prosthodontist when the situation gets complicated: multiple missing teeth, a bite that needs to be rebuilt from scratch, implants that require careful planning, or teeth so badly damaged that standard restorations won’t work. If you’ve had cancer surgery affecting your mouth or face, or suffered facial trauma, a prosthodontist with maxillofacial training is typically part of the reconstruction team.
People who have struggled with ill-fitting dentures are also good candidates, since prosthodontists spend years training specifically on optimizing how removable prosthetics fit and function. The same applies if you have TMJ problems that require splint therapy or if you need a night guard for sleep apnea and want a specialist-level fit.
