Quick answer. A dental crown is a cap that covers and protects a damaged, heavily filled or root-canal-treated tooth, restoring its shape and strength. A bridge replaces missing teeth by anchoring a false tooth to crowns on the adjacent teeth. Common materials include all-ceramic/porcelain (best for natural appearance, often front teeth), zirconia (very strong with good aesthetics) and porcelain-fused-to-metal or full-metal (durable, often for back teeth). A bridge is fixed but trims neighbouring teeth, whereas an implant is standalone. Well-made crowns and bridges can last many years with good oral hygiene. Costs in Singapore vary by material and clinic; CHAS subsidies for crowns are available to eligible Singaporeans at participating clinics.

When a tooth is badly broken, cracked, heavily filled or has had root canal treatment, a simple filling may not be enough to keep it strong. A crown covers the whole tooth to protect it, while a bridge uses crowns to replace one or more missing teeth in a fixed (non-removable) way.
This guide explains when crowns and bridges are needed, the materials available in Singapore, how a bridge compares with a dental implant, how long they last, and what affects cost – including CHAS subsidies for eligible Singaporeans.
At a glance
| Material | Strengths | Best suited for |
|---|---|---|
| All-ceramic / porcelain | Most natural look and translucency | Front teeth and visible areas |
| Zirconia | Very strong and durable, good aesthetics | Back teeth or anywhere needing strength |
| Porcelain-fused-to-metal (PFM) | Strong with a tooth-coloured surface | Crowns and bridges where strength matters |
| Full metal / gold alloy | Extremely durable, gentle on opposing teeth | Back (molar) teeth, less visible |
When are crowns or bridges needed?
A crown is commonly recommended when a tooth is:
- Heavily decayed or has a very large filling that leaves little tooth structure
- Cracked, weakened or at risk of breaking
- Treated with root canal therapy (these teeth become brittle and often need a crown to protect them)
- Being used to support a bridge or to improve a tooth’s shape
A bridge is used to replace one or more missing teeth. It fills the gap with an artificial tooth (pontic) that is held in place by crowns cemented onto the natural teeth (or implants) on either side.
Crown and bridge materials
- All-ceramic / porcelain: offers the most natural appearance, closely matching the colour and translucency of real teeth – often chosen for front teeth.
- Zirconia: a very hard, strong ceramic with good aesthetics, suitable for both front and back teeth and resistant to chipping.
- Porcelain-fused-to-metal (PFM): a metal core for strength with a porcelain outer layer for a tooth-coloured look.
- Full metal / gold alloy: extremely durable and kind to opposing teeth, usually reserved for less visible back teeth.
Your dentist balances appearance, strength and the position of the tooth when recommending a material.
Bridge vs implant for a missing tooth
Both can replace a missing tooth, and the right choice depends on your teeth, gums and bone, as well as cost and timeline:
- Bridge: fixed and usually completed in a few weeks. However, it requires trimming the neighbouring teeth to hold the crowns, even if those teeth are healthy.
- Dental implant: a titanium post placed in the jaw that supports a standalone crown, so neighbouring teeth are left untouched and jawbone is preserved. It involves surgery and takes longer to complete.
Implant surgery may be MediSave-claimable as a surgical procedure, whereas crowns and bridges are routine dental work and are not MediSave-claimable.
How long do crowns and bridges last?
Well-made and well-maintained crowns and bridges can last many years. Longevity depends on:
- Oral hygiene: brushing twice daily, cleaning under bridges (with floss threaders or interdental brushes), and regular check-ups
- Habits: avoiding chewing very hard items or grinding; a night guard may help if you grind your teeth
- The underlying tooth and gum health: decay or gum disease at the margins can shorten lifespan
Routine reviews let your dentist spot problems early and help your restorations last longer.
Cost and CHAS subsidies
The cost of crowns and bridges in Singapore varies by material (zirconia, porcelain, PFM, metal), the number of units in a bridge and the clinic. A bridge costs more than a single crown because it involves multiple units. Always ask for a written estimate that includes any root canal or build-up that may be needed first.
Eligible Singaporeans can receive CHAS subsidies for dental crowns at participating clinics, with stronger support for Pioneer Generation, Merdeka Generation, CHAS Blue and CHAS Orange cardholders. As crowns involve several visits, subsidies are typically claimed after the treatment is completed.
What to expect during treatment
A crown or bridge usually takes more than one visit. At the first, the dentist prepares the tooth (or teeth), takes an impression or digital scan, and fits a temporary crown. The permanent restoration is made in a laboratory and cemented at a later visit, with adjustments to make sure it bites comfortably. If the tooth needs root canal treatment or a build-up first, that is done before the crown. Tell your dentist if the bite feels high, if there is lingering sensitivity, or if a temporary crown comes loose, as these are easily corrected.
Costs, subsidies and MediSave
Costs vary widely by material, the number of units in a bridge and the clinic, so ask for a written estimate that includes any preparatory work. Eligible Singaporeans can receive CHAS subsidies for crowns at participating clinics, with stronger support for Pioneer Generation, Merdeka Generation and CHAS Blue and Orange cardholders. Routine crowns and bridges are not MediSave-claimable, though implant surgery may be. Seniors should ask their clinic about Flexi-MediSave, which can help offset certain procedures such as crowns at CHAS and public dental clinics – confirm your eligibility and current limits directly, as schemes are updated over time.
Common questions
How long will a crown or bridge last?
Well-made restorations can last many years with good oral hygiene, regular check-ups and by avoiding chewing very hard items. A night guard helps if you grind your teeth.
Should I choose a bridge or an implant?
A bridge is quicker but trims the neighbouring teeth, while an implant is standalone and preserves them but needs surgery and more time. Your dentist will advise based on your teeth, gums and bone.
How do I clean under a bridge?
Use floss threaders or interdental brushes to clean beneath the false tooth, as a normal brush cannot reach there.
