Crowns cover a tooth too damaged for a filling; bridges span a gap using the teeth on either side. Both involve preparing tooth structure, which is why the alternatives are worth understanding first: see how much a dental crown costs and implant versus bridge. A crown covers and protects a tooth that has been weakened by decay, a large filling or a root canal, and a bridge joins crowns on either side of a gap to replace a missing tooth, and both depend on healthy support underneath, which is why the gums and remaining tooth structure are checked first.
What usually brings up dental crowns and bridges
Restorative treatment addresses damage, decay or wear that's already happened. What's right depends much more on how much healthy tooth is left than on the procedure name you came in with.
- A large filling or weakened tooth
- A tooth after root-canal treatment
- A cracked or heavily worn tooth
- A gap from one or more missing teeth
When a crown or bridge is usually proposed
Crowns cover a weakened tooth; bridges span a gap using the teeth either side. Different problems, different answers.
- A tooth broken down beyond what a filling can hold
- A tooth that has had root-canal treatment
- A cracked tooth that needs holding together
- A large old filling repeatedly breaking
- One or more missing teeth with sound teeth either side
- A failed existing crown or bridge
Treatment paths a dentist may weigh
Almost every case has more than one defensible path forward, including a more conservative one. Expect the alternatives, and what waiting changes, to be part of the conversation.
- Crown, onlay, or bonded restoration
- Conventional or implant-supported bridge
- Single dental implant
- Removable partial denture
What the process involves
A conventional crown or bridge is usually two appointments with laboratory work in between.
- Assessment, X-ray and a discussion of materials
- Preparing the tooth and building up the core if needed
- An impression or digital scan, and shade matching
- A temporary crown while the laboratory makes the final one
- Fitting, adjusting the bite and cementing
- A same-day option where the practice offers it
How the treatment is planned
An examination plus X-rays decides what stays and what goes. The recommended approach, the reasonable alternatives, the expected number of visits, and what could change along the way should all be explained from there.
Ask what the written estimate leaves out, not just what it includes. Build-ups, root canals and lab work are the usual separately-priced items: see dental insurance and financing.
What else could be done
A crown is not automatically the right answer, and neither is a bridge.
- A large filling where enough sound tooth remains
- An inlay or onlay to preserve more structure
- A single implant instead of a bridge: see implant versus bridge
- A partial denture as a lower-cost gap solution
- Accepting the gap, where the position allows

How long crowns and bridges last in the literature
A systematic review of single tooth-supported crowns found five-year survival between about 95.7 and 98.5 percent across materials: monolithic lithium-disilicate glass-ceramic at the top, veneered zirconia and metal-ceramic in the middle at 97.3 and 97.1 percent, and monolithic zirconia at 96.8 percent. Metal-ceramic crowns are commonly cited at about 95 percent at ten years.
Bridges do worse than crowns. The same body of research finds three-unit bridges survive significantly less well than single crowns at five and ten years, because a bridge fails when either supporting tooth does. That is the reason to compare a bridge with an implant on the health of the neighbouring teeth, and not on price alone.
Common questions
Dental Crowns and Bridges: questions people ask
How long does a crown last?
Well-made crowns commonly last many years, but it depends on the tooth underneath, your bite, gum health and cleaning. Grinding shortens the life of anything: see teeth grinding.
Does a crowned tooth still decay?
Yes, at the margin where the crown meets the tooth. That edge is exactly where cleaning matters most, and it is why crowns still need check-ups.
Why does a bridge mean cutting healthy teeth?
A conventional bridge uses the neighboring teeth as supports, which means preparing them. If those teeth are otherwise untouched, that is the main argument for an implant instead.
What materials are used?
All-ceramic, zirconia, porcelain-fused-to-metal and gold each have different strengths and appearance. The right choice depends on the tooth's position and your bite: ask which is proposed and why.
What does a crown actually cost?
It depends on what sits underneath as much as the crown itself. See how much a dental crown costs for what a quote should itemize.
Can I eat with a temporary crown?
Yes, carefully. Avoid sticky foods that can pull it off, and pull floss out sideways rather than up through the contact.
Should I get a second opinion on a large plan?
For anything large, expensive or irreversible it is reasonable, and a good practice will not object: see when to get a second dental opinion.
