What Is the Difference Between Crowns and Bridges?

Introduction: Crowns vs Bridges, Made Simple

Crowns and bridges are fixed dental restorations that look natural and stay in your mouth. They solve different problems. A dental crown restores and protects a damaged tooth, while a dental bridge fills a gap where a tooth is missing.

This guide explains the difference between crowns and bridges, when each is recommended, treatment steps and easy care tips. If you are exploring confidence-boosting options more widely, you may also enjoy our blog on how to smile with confidence.

Suitability always depends on your mouth and goals. This article is informational and does not replace an examination with a dentist.

A dental crown is a custom-made cap that covers a prepared tooth. It restores strength, shape and appearance, and protects the tooth underneath. You might also hear it called a tooth crown.

Common reasons we may recommend a crown include:

• A cracked or heavily filled tooth at risk of further breakage

• After root canal treatment to reinforce a weakened tooth

• Severe wear, or to improve shape or alignment

• To complete a dental implant as the visible part of the tooth

Crowns come in different materials. Options include porcelain for natural aesthetics, zirconia for strength with a good appearance, metal alloys for back teeth where durability is key, and porcelain-fused-to-metal which blends strength and looks. We help you choose based on the tooth’s position, bite forces and your preferences. If you have any metal sensitivities, please tell us so we can plan an appropriate material such as a porcelain crown or zirconia crown.

Typical steps to fit a crown:

1. Assessment and planning, sometimes including X-rays

2. Numbing the tooth and shaping it to allow room for the crown

3. Taking an impression or digital scan, then placing a temporary crown

4. Fitting and bonding your custom crown, checking bite and appearance

A dental bridge fills a gap by anchoring a false tooth, called a pontic, to neighbouring teeth or to dental implants. It is a fixed bridge, so it stays in place and is not removed at home. Bridges can replace one missing tooth or several in a row, providing predictable missing tooth replacement.

Common bridge types include:

• Traditional bridge, using crowns on the neighbouring teeth to support the pontic

• Cantilever bridge, supported on one side only in selected cases

• Resin-bonded bridge, often called a Maryland bridge, which bonds to the back of a neighbouring tooth with minimal preparation

• Implant-supported bridge, which attaches to dental implants and can avoid preparing adjacent natural teeth

Typical steps to fit a bridge:

1. Assessment of gum health, bite and the strength of supporting teeth

2. Agreeing the best bridge type for your mouth and goals

3. Preparing abutment teeth if needed, taking impressions or scans, and fitting a temporary solution

4. Trying in, adjusting and bonding the final bridge

Purpose: A crown repairs and protects a single existing tooth. A bridge replaces one or more missing teeth by filling a gap.

Tooth impact: A crown focuses on one tooth. A traditional bridge often requires preparing one or two neighbouring teeth to act as supports.

Function and appearance: Both can restore chewing comfort and your smile’s appearance when carefully planned and maintained.

Alternatives: For a single missing tooth, a dental implant may be discussed if you wish to avoid preparing healthy neighbouring teeth.

While we cannot diagnose here, the following examples may help:

• Broken or heavily filled but savable tooth, including after root canal: likely a crown

• One missing tooth with strong neighbours: a bridge or a dental implant may be discussed

• Several missing teeth in a row: a multi-unit bridge or an implant-supported solution

Your dentist will examine the condition of the tooth or gap, gum health, bite, signs of teeth grinding, and your goals. We then explain the pros and cons in plain English so you can decide with confidence.

Most crown and bridge treatments take two appointments after your initial assessment:

• Visit 1: Numbing for comfort, tooth preparation if required, impressions or scans, and a temporary crown or bridge where appropriate

• Between visits: Your final restoration is crafted by the dental laboratory

• Visit 2: Try-in, adjustments for bite and fit, then final bonding

Mild sensitivity after preparation is common and usually settles quickly. We provide at-home advice to keep you comfortable between visits. If you experience severe pain, swelling or trauma, please contact us promptly. If you have difficulty breathing or swallowing, or feel very unwell, seek urgent medical help.

With good care and regular check-ups, crowns and bridges can last many years. Daily home care and routine visits are the key to protecting the edges, called margins, where the restoration meets the tooth or gum.

Simple care tips:

• Brush twice daily with fluoride toothpaste

• Clean between teeth every day with floss or interdental brushes

• For bridges, use super floss or an interdental brush to clean under the pontic. Our hygienists can show you the simplest technique

• Be mindful with very hard or sticky foods, especially while you get used to your new restoration

• If you grind your teeth, consider a protective night guard

• Keep up regular examinations and hygiene visits so we can monitor your bite, margins and gum health

Bridges are a well-established solution for missing tooth replacement. In many cases we also discuss dental implants. A dental implant is a small titanium post that acts like a new root for your tooth. It can support a custom crown or bridge without preparing neighbouring teeth. Learn more on our page about dental implants and in our patient-friendly dental implants guide.

Modern dentures can also be suitable for certain situations. They are removable, which some patients like for cleaning, and can work well for multiple missing teeth. We will explain how each choice fits your mouth, lifestyle and budget, and outline the steps and maintenance involved. Patients with active gum problems should have this managed before crown, bridge or implant treatment.
