Two of the most common questions I get from new patients: "Do I really need a crown?" and "What's the difference between a bridge and an implant?" Both are reasonable questions, and the answers matter — these decisions affect not just how your teeth look, but how they function for the next 15-30 years.
Let me walk you through what crowns and bridges actually are, when each is the right choice, and how modern materials have changed what's possible.
Dental crowns — when and why
What a crown is
A crown is a custom-made cap that covers the entire visible portion of a tooth, restoring its shape, size, strength, and appearance. Think of it as a protective shell that wraps around what's left of a damaged tooth.
When you need one
Crowns are recommended when a tooth is too damaged or weakened to be restored with a simple filling, but the root and underlying structure are still sound. The most common scenarios:
- After a root canal. A root-canaled tooth is structurally weaker and more prone to fracture. A crown protects it.
- A large existing filling that's failing. When the filling is bigger than the remaining tooth, the tooth can split. A crown prevents that.
- A cracked or fractured tooth. A crown holds the tooth together and prevents the crack from propagating.
- Severely worn teeth. Years of grinding or acid erosion can shorten teeth significantly. Crowns restore proper height and bite.
- Cosmetic transformation. Severely discolored, misshapen, or damaged teeth that aren't candidates for veneers.
- To support a dental bridge or implant. The crown is the visible tooth-shaped part of an implant or bridge.
The crown procedure
Traditionally, getting a crown takes two appointments:
- First visit: We numb the tooth, remove damaged structure, and shape the remaining tooth to receive a crown. We take a digital scan, place a temporary crown, and send the data to a lab.
- Second visit (2-3 weeks later): We remove the temporary, check the fit of the permanent crown, make any adjustments, and bond it permanently.
Some practices offer same-day crowns using CEREC technology. Both approaches have their place — we'll discuss which fits your specific situation.
Materials matter
Crowns can be made from:
- All-ceramic (zirconia, lithium disilicate) — strongest current materials, completely metal-free, excellent aesthetics. What we use for most cases.
- Porcelain-fused-to-metal (PFM) — older technology, durable but can show a dark line at the gum over time. We rarely use these now.
- Gold or other metal alloys — extremely durable for back teeth where appearance doesn't matter, but most patients prefer ceramic.
For visible front teeth, ceramic is the right choice. For molars under heavy bite force, zirconia ceramic offers strength comparable to metal with much better aesthetics.
Dental bridges — replacing missing teeth
What a bridge is
A bridge replaces one or more missing teeth by anchoring artificial teeth (called "pontics") to the natural teeth on either side of the gap. Those anchor teeth get crowns, and the artificial teeth in the middle are fused to those crowns.
When a bridge makes sense
Bridges are still appropriate in specific situations:
- You're missing one or a few adjacent teeth
- The teeth on either side of the gap are healthy or have existing crowns/large fillings that already needed restoration
- You don't have enough bone for implants and bone grafting isn't an option
- You need a faster solution than implants (2-3 weeks vs 4-6 months)
- Cost is a significant factor (bridges are typically less expensive than implants up front)
The trade-offs vs implants
A bridge requires shaping down the teeth on either side of the gap to support crowns. If those teeth were healthy, you've now committed them to having crowns for the rest of their lives. Bridges also don't preserve the bone underneath the missing tooth — that bone gradually shrinks over years.
A dental implant, by contrast, replaces just the missing tooth without affecting the neighbors. It preserves bone. It typically lasts longer. But it costs more up front and takes longer.
My general recommendation for most patients with a single missing tooth and healthy adjacent teeth: an implant is the better long-term investment. For older patients, patients with health conditions that make implants difficult, or specific clinical situations — a bridge is still a great solution.
How long do crowns and bridges last?
With proper care, expect:
- Crowns: 15-30 years. Modern zirconia crowns we place today should last 20+ years for most patients.
- Bridges: 10-20 years. The lifespan depends heavily on how the supporting teeth hold up.
- Implants and implant crowns: 25+ years for the implant body, 15-20 years for the crown on top.
The biggest threats to crown and bridge longevity:
- Grinding and clenching. The #1 cause of restoration failure. If you grind, you need a custom night guard. Period.
- Decay at the margin. The seam where the crown meets the tooth is vulnerable to new cavities if you don't floss it carefully.
- Gum disease. Bone loss around supporting teeth weakens the foundation. Periodontal maintenance matters.
- Trauma. Sports without a mouthguard, biting on something hard, accidents.
Caring for crowns and bridges at home
Crowns and bridges aren't maintenance-free. They need the same attention as natural teeth, with a few additions:
- Brush twice daily, floss daily — including under the artificial tooth on a bridge using a floss threader or super floss
- Avoid biting extremely hard foods (ice, popcorn kernels, hard candy) — they can crack any ceramic
- Wear a night guard if you clench or grind
- Wear a sports mouthguard for contact activities
- Don't use your teeth as tools (opening packages, biting fingernails)
- See your dentist every 6 months so we can check the margins and fit
What it costs
Approximate fees for Jupiter, FL:
- Single ceramic crown: $1,400-$2,200
- Three-unit bridge: $3,500-$5,500
- Single implant + crown: $3,500-$6,000
Most dental insurance covers 50% of crown and bridge costs after deductible, up to the annual maximum. See our insurance page for details on what your specific plan typically covers. For larger restorations, we offer Cherry financing with 0% APR options.
When to come in
See a dentist if you have:
- A tooth that's cracked, broken, or has a large old filling that's failing
- Recent or upcoming root canal treatment
- A missing tooth (recently lost or long-missing)
- A bridge that's getting old or feels loose
- Concerns about the appearance of crowns from previous dental work
