Dental words explained

Every word a clinic is likely to use on a quote or in a video call, in the order you are most likely to meet them. Medical definitions carry a source number; the list is at the bottom.

Teeth, jaws and scans

Arch. One full row of teeth, upper or lower. "Full arch" means every tooth in that jaw.

Extraction. Pulling a tooth. Dentists recommend it when a tooth is too broken, decayed or loose to fix. Most people are back to normal activities in 48 to 72 hours; the bone underneath takes several weeks to heal 1.

Periodontal disease (gum disease). An infection of the tissues that hold your teeth in place. In advanced cases it destroys the bone under the teeth, which loosens them. Smoking is the biggest risk factor. Early gum disease can often be reversed with daily brushing and flossing; advanced cases need deep cleaning or surgery 2. Clinics check for it before placing implants.

Panoramic X-ray. One wide, flat picture of the whole mouth, both jaws and the sinuses. Used to plan dentures, extractions and implants. It does not show fine detail of each tooth 3.

CT or CBCT scan. A 3D X-ray of the teeth, jaws, nerves and sinuses, used to plan where implants go. It uses more radiation than a normal dental X-ray, so it should only be taken when needed 4,5.

Pulp. The soft tissue inside a tooth that holds the nerve and blood vessels. When it gets infected, you need a root canal or an extraction 6.

Implants

Dental implant. A small threaded post, usually titanium, placed in the jawbone to replace a tooth root. On a quote, "implant" or "implant only" often means the post alone, without the connector or the tooth 7.

Abutment. The small connector that screws into the implant and holds the crown, bridge or denture. Sometimes priced separately 7.

Crown on implant. The visible tooth that attaches to the abutment 7.

Osseointegration. Bone growing around the implant until it is locked in place. The ADA says it can take several months 8; Cleveland Clinic gives three to nine months 7. Nothing final goes on the implant until this is done.

Immediate load, or "teeth in a day". Fitting temporary teeth onto implants on the day of surgery instead of waiting months. Common with All-on-4 9.

Temporary teeth. The placeholder crown, bridge or denture you wear while the implants fuse or the lab makes the final version. Usually acrylic. Ask whether it is in the quote and what happens if it breaks.

Bone graft. Powdered bone material added where the jaw is too thin to hold an implant. It can be your own bone, donor bone, animal bone or a synthetic. It needs at least three months to knit and can take up to a year to heal fully 10.

Sinus lift. A graft under the sinus in the upper back jaw, where bone is often thin. Healing takes about six to eight months before implants can carry teeth. A tear in the sinus membrane is the most common complication 11.

Implant brand. The company that makes the post. Ask for the brand and lot number in writing so a dentist at home can find matching parts later. The sources we opened do not compare brands, and this guide does not either.

Peri-implantitis. An infection around an implant that causes bone loss. Reported in 10% to more than 40% of cases depending on how it is measured. Past gum disease, smoking, uncontrolled diabetes and poor cleaning raise the risk 12.

Full-arch options

All-on-4. A full row of fixed teeth for one jaw on four implants: two straight at the front, two tilted up to 45 degrees at the back. The tilt often avoids a bone graft or sinus lift 9.

All-on-6. The same idea on six implants. In one clinical study, two at the front and four at the back 13.

All-on-X. The family name for a full fixed row on any number of implants.

Final bridge. The permanent row of teeth screwed onto the implants once they have fused. Also the name for a false tooth held by crowns on the teeth either side of a gap, which lasts five to 15 years on average 14.

Acrylic (PMMA) bridge. A full-arch bridge made of dental plastic, often on a metal frame. Used for temporary bridges and some final ones. In a review of 25 All-on-4 studies, fracture of the acrylic bridge was the main complication, mostly in people who grind 9.

Zirconia bridge. A full-arch bridge milled from zirconia. A 2026 review of 12 studies found less wear and fewer lost bridges than acrylic, though the authors rated the evidence moderate to very low 15.

Snap-on denture. A removable denture that clips onto implants so it does not slip or need glue. Also called an implant-retained denture 16,17.

Overdenture. A denture that sits over implants or over a few remaining teeth. A snap-on denture is one kind 17,18.

Immediate denture. A denture fitted the same day your teeth are pulled. It often needs relining or replacing once the gums heal and shrink, up to a year later 18,19.

Reline. Refitting the inside of a denture as your gums change shape. Cleveland Clinic says every one to two years 16.

Crowns and veneers

Crown. A tooth-shaped cap cemented over a damaged tooth, or attached to an implant. Lasts five to 15 years on average 20.

Zirconia. A hard white ceramic. Cleveland Clinic calls zirconia crowns "extremely durable" 20.

e.max. A brand of glass ceramic called lithium disilicate, used for crowns and veneers. In a review of 13 studies, five-year survival was 96.6% for lithium disilicate crowns and 96% for zirconia 21.

PFM. Porcelain fused to metal. A metal shell with porcelain on top. Strong, but the porcelain can chip and show the metal over time 20.

Veneer. A thin shell bonded to the front of a tooth to hide chips, stains or gaps. Fitting one removes some enamel for good 22,23.

Composite. Tooth-colored filling material. Composite veneers are built straight onto the tooth in fewer visits, but stain and wear faster than porcelain 22.

Root canal. The hollow inside a tooth root, and the treatment that cleans out infected pulp, fills the space and seals the tooth. Usually one or two visits, then a crown 6,24.

Paperwork

Warranty. A clinic's written promise to repair or replace work that fails within a set time. Read what it excludes (grinding damage, missed check-ups, smoking) and who pays for travel if you have to come back. Not a medical term, so no source; it is whatever the clinic puts in writing.

Treatment plan. The written list of what the clinic proposes to do, in what order, on which visits, and at what price. Get one from every clinic before you compare.
