Heavily restored tooth
A large filling may leave limited natural structure and increase the need for protective coverage.
Dental crowns cover and protect selected damaged teeth, while dental bridges replace missing teeth by joining an artificial tooth to supporting teeth or dental implants.
Crowns and bridges are custom-made restorations. The right option depends on how much tooth structure remains, the condition of supporting teeth and gums, your bite, the location of the gap and available alternatives.

A crown can protect a tooth with substantial structure loss, but it cannot compensate for an untreated crack, infection or poor gum support. A bridge also relies on healthy supporting teeth or implants, so assessment comes before design.
A large filling may leave limited natural structure and increase the need for protective coverage.
A crown may help protect selected teeth after the crack, bite and pulp health are assessed.
Some root-filled teeth benefit from cuspal coverage to reduce fracture risk.
A bridge may restore a gap when supporting teeth or implants are suitable.
Treatment recommendations depend on the findings, your health history and your preferences.
Assess tooth structure, gums, bite, X-rays and alternatives before choosing a restoration.
Shape the tooth as required and take a scan or impression; a temporary restoration may be placed.
Check the final restoration’s fit, contact and bite, then explain cleaning and review needs.
| Option | Typical purpose | Key consideration |
|---|---|---|
| Dental crown | Protect and restore one weakened tooth | Requires suitable remaining tooth and support |
| Tooth-supported bridge | Replace a gap using neighbouring teeth | Supporting teeth are prepared for crowns |
| Implant-supported crown or bridge | Replace teeth without preparing neighbours | Requires surgical and bone assessment |
| Removable denture | Replace one or several teeth | Removable and may need adjustment over time |
This page provides general information. A dentist needs to assess your mouth before recommending treatment. Risks, benefits, alternatives and likely costs vary.
A crown is a custom restoration that covers the visible part of a prepared tooth to restore shape, strength and function.
A bridge replaces one or more missing teeth with artificial teeth connected to crowns or implants on either side of the space.
Longevity varies with material, bite, cleaning, diet, tooth support and maintenance. They are not lifetime restorations and need regular review.
Local anaesthetic is used when preparing a natural tooth. Temporary sensitivity or gum tenderness can occur and should be discussed if it persists.
The artificial tooth needs cleaning underneath using suitable floss, threaders or interdental aids. The dental team can demonstrate a method for your bridge.
Neither is automatically better. Suitability depends on neighbouring teeth, bone, health, surgery preferences, timing, cost and maintenance.
Arrange an assessment to discuss the concern, available options and likely fees.
