Dental Terms Glossary

How to use this glossary

Most glossaries hand you a flat A-to-Z wall of definitions and stop there. Ours is built for the moment a strange word lands on your bill. Terms are grouped by where you run into them — implant and surgery work, restorations and cosmetic work, orthodontics, complications, and the insurance language that decides what you pay. Definitions are written in plain English and checked against the American Dental Association's CDT Glossary, the U.S. reference standard. Where a term carries a real price, we link it to our independent cost guide so the definition is genuinely useful, not just a dictionary entry.

Implant & oral surgery terms

These appear on quotes for replacing missing teeth and on the surgical steps that often come first.

• All-on-4 — A full arch of replacement teeth supported by four implants, used when most or all teeth in a jaw are missing. All-on-4 cost guide →
• All-on-6 — The same full-arch concept using six implants for extra support and load distribution, often chosen for the upper jaw.
• Abutment — The connector that screws onto an implant post and holds the visible crown; frequently billed separately. Implant abutment guide →
• Bone graft (dental) — A procedure that rebuilds lost jawbone so an implant has enough volume to anchor into; the most common reason an implant quote rises. Bone graft cost guide →
• Sinus lift — Upper-jaw bone augmentation that lifts the sinus floor to make room for an implant when natural bone height is too low. Sinus lift cost guide →
• Osseointegration — The healing process, usually three to six months, in which the jawbone fuses to the implant surface and makes it stable enough for a crown.

Restoration & cosmetic terms

The words for rebuilding, covering or improving the look of a tooth.

• Zirconia crown — A tooth-colored crown made from strong, stain-resistant zirconia ceramic; a premium alternative to porcelain-fused-to-metal. Zirconia crown cost guide →
• Porcelain veneers — Thin custom shells bonded to the front of teeth to change shape, color or alignment; a lab-made cosmetic restoration. Porcelain veneers cost guide →
• Composite bonding — Tooth-colored resin shaped directly onto a tooth in one visit to repair chips or close gaps; the lower-cost cosmetic option. Composite bonding cost guide →
• Crown (cap) — A full cover cemented over a damaged tooth to restore its shape and strength; "cap" is the everyday word, "crown" the clinical and insurance term.
• Pontic — The artificial replacement tooth that bridges the gap in a dental bridge, anchored to the teeth or implants on either side.

Orthodontic terms

The vocabulary of straightening and stabilizing teeth.

• Retainer — A fixed or removable appliance worn after braces or aligners to hold teeth in their corrected position and stop them drifting back. Retainer cost guide →
• Malocclusion — A "bad bite": the upper and lower teeth do not meet correctly, the clinical reason most orthodontic treatment is recommended.
• Occlusion — The way the upper and lower teeth come together when the jaw closes; clinicians assess it before and after treatment.

Conditions & complications

Diagnoses and post-procedure problems you may see explained.

• Dry socket — A painful complication a few days after an extraction when the protective blood clot is lost and bone is exposed; usually needs a follow-up visit.
• Caries — The clinical word for tooth decay, or "cavities" — surfaces destroyed by acid from bacteria.
• Gingivitis — Early, reversible gum inflammation caused by plaque; left untreated it can progress to periodontitis.
• Periodontitis — Advanced gum disease in which the bone and tissue supporting the teeth break down, leading to loosening and tooth loss.
• Bruxism — Habitual grinding or clenching of the teeth, often during sleep, commonly managed with a night guard.

Insurance & billing terms

The language that actually decides what comes out of your pocket.

• Annual maximum — The total your plan will pay in one benefit year, commonly $1,000 to $2,000; you pay everything above it.
• Deductible — The amount you pay yourself before the plan starts contributing toward covered care.
• Coinsurance — Your share of a covered service after the deductible, written as a percentage (for example, the plan pays 80%, you pay 20%).
• Waiting period — A stretch of time, often 6 to 12 months, before a new plan will cover major work such as crowns or dentures.
• CDT code — The standardized Current Dental Terminology code (such as D6010) a dentist puts on a claim to identify each procedure for insurance.
• EOB (Explanation of Benefits) — The statement your insurer sends after a claim showing what was billed, what the plan paid and what you owe; it is not a bill.

Why a glossary that links to costs matters

When an unfamiliar term shows up on a quote, the definition alone rarely answers the real question: is this price fair? The competing glossaries from insurers, dental groups and health portals all stop at the dictionary entry. By connecting each priced term to an independent benchmark, this index lets you decode a treatment plan and sanity-check the numbers on it. Start with the term, read the definition, then follow the link to the cost guide before you say yes to treatment.
