In short: a crown is a cap that covers a damaged or root-treated tooth and restores its strength. A bridge replaces one or more missing teeth by anchoring to the teeth either side. Both are made in a laboratory and cemented in place — you do not take them out.
When you need a crown
A filling replaces missing tooth material. A crown replaces the outer shell of the tooth entirely, holding what remains together. You need one when:
- The tooth has had a root canal. A root-treated back tooth has lost its blood supply and had material removed from its core. It becomes brittle and can split under normal chewing force — and a split root usually cannot be saved. Crowning it after RCT is not an upsell, it is what protects the treatment you just paid for.
- The tooth is heavily filled. When more of the biting surface is filling than tooth, the remaining walls are unsupported and will eventually fracture.
- The tooth is cracked. A crown holds the segments together and stops the crack propagating.
- A large piece has broken off, from trauma or decay.
- The tooth is badly worn from grinding, and its height needs rebuilding.
- Cosmetic reasons — a badly shaped or discoloured tooth, though a veneer may be the more conservative option.
- To anchor a bridge or to restore an implant.
The materials, and how to choose
Zirconia
Extremely strong, tooth-coloured, metal-free, and biocompatible. Modern layered zirconia is aesthetic enough for front teeth and tough enough for molars. For most patients today this is the default recommendation.
All-ceramic (E-max and similar)
The best light behaviour and translucency of any material — it looks the most like natural enamel. Ideal for front teeth. Slightly less strong than zirconia, so we are more careful about using it on molars in patients who grind.
Porcelain fused to metal (PFM)
Ceramic over a metal core. Long track record and durable, but the metal margin can show as a dark line at the gum over the years as gums recede, and it is more opaque. Still a reasonable, economical choice for back teeth.
Full metal
Very strong and needs the least tooth removal. Appearance rules it out for visible teeth, but for a last molar in a heavy grinder it remains a genuinely sensible option.
We will discuss which suits your tooth, your bite and your budget rather than applying one material to everything.
What is a bridge?
A bridge fills a gap using the teeth on either side as supports. The supporting teeth are prepared for crowns, and the replacement tooth in the middle is joined to them as one solid unit that is cemented into place.
The trade-off to understand: to place a conventional bridge, healthy enamel is removed from the two supporting teeth, permanently. If those teeth are already crowned or heavily filled, that costs you nothing extra and a bridge is an excellent choice. If they are pristine, a dental implant replaces the missing tooth without touching them at all — and we will usually recommend the implant in that situation. A bridge is faster and cheaper; an implant preserves your other teeth and the bone underneath. Both are legitimate; the right answer depends on your mouth.
What the appointments look like
- Assessment and X-ray. We confirm the tooth is restorable and the supporting bone is sound.
- Preparation. Under local anaesthesia, the tooth is shaped to make room for the crown. An impression or digital scan is taken, along with a shade match against your natural teeth in good light.
- Temporary crown. Fitted the same day so you are never left with an exposed prepared tooth.
- Fitting. Around one to two weeks later, the permanent crown is tried in, checked for fit, contact with neighbouring teeth, bite and appearance — and adjusted before it is cemented. Speak up at the try-in if the shape or shade is not right. Adjusting then is easy; after cementation it is not.
Living with a crown or bridge
- A little sensitivity to cold for a week or two after fitting is normal and settles.
- If the bite feels high — if that tooth hits first when you close — come back. It takes a two-minute adjustment, and leaving it causes soreness and can crack the crown.
- You must clean under a bridge. A superfloss or an interdental brush threaded beneath the false tooth, daily. Debris trapped there causes gum inflammation and decay in the supporting teeth, which is the usual reason bridges fail.
- Crowns cannot decay — but the natural tooth underneath, at the margin, absolutely can. Brush that margin carefully.
- Avoid biting ice, hard nuts and bones on crowned teeth. Wear a night guard if you grind.
How long do they last?
Ten to fifteen years is a common working figure, and many last considerably longer with good hygiene and regular check-ups. What ends them is decay at the margin, gum recession exposing the edge, and fracture from grinding — all three are largely within your control.
Crowns and bridges in Jabalpur
Zirconia, all-ceramic, PFM and metal crowns, and fixed bridges, are all provided at our Madan Mahal clinic with shade matching done in natural light and a full bite check before cementation. If a crown or bridge has come loose, keep it safely and bring it in — a recently dislodged crown can very often be re-cemented rather than remade.
