A crown covers a tooth; a bridge replaces a gap
A crown is fitted over an existing tooth that has been prepared to receive it. A bridge replaces one or more missing teeth using support from other teeth or, in some cases, implants. Although both are fixed restorations, they address different situations.
A damaged tooth does not automatically need a crown, and a missing tooth does not automatically need a bridge. The decision depends on the teeth and gums, your bite, the likely function of the restoration and your preferences.
What supporting a bridge can involve
A conventional tooth-supported bridge often requires preparation of teeth next to the gap. This can involve removing otherwise healthy tooth structure. Other bridge designs may be considered in selected cases. Ask which teeth would be involved and what would happen if a supporting tooth developed a problem.
A bridge needs cleaning beneath the replacement tooth as well as around its supports. Your dentist can demonstrate an appropriate method. A crown or bridge does not prevent future tooth decay or gum problems.
Discuss the alternatives and risks
Depending on the tooth, alternatives to a crown may include a filling or partial-coverage restoration. Options for a gap may include an implant, a removable denture or leaving the space with monitoring. Each has different requirements, risks and maintenance needs.
Crowns and bridges may chip, loosen or fracture, and supporting teeth can develop sensitivity or require further treatment. Ask about the risks of delaying or declining care, and whether referral to a prosthodontist would help with a complex decision.
Before proceeding with invasive treatment, consider seeking a second opinion from an appropriately qualified dental practitioner.
