Sometimes a filling isn’t enough to repair a damaged tooth.
When decay or cracks are too extensive for a simple filling—but not severe enough to require extraction—crowns and onlays provide the perfect solution. At York House Dental Practice in West Byfleet, Surrey, modern crowns and onlays are used to strengthen teeth, restore function, and maintain a natural smile.
Think of them as protective shields. They don’t just repair damage—they prevent further problems and give your tooth a second life.
What Are Crowns and Onlays?
- Crown: A tooth-shaped “cap” that completely covers the tooth, restoring its strength, shape, appearance, and bite.
- Onlay: Sometimes called a “partial crown,” it covers only the damaged portion of the tooth while preserving as much natural structure as possible.
Procedure Steps
- Examination & X-rays – to assess tooth health and strength
- Tooth Preparation – shaping the tooth so the restoration fits properly
- Impressions/Scans – digital or physical molds are taken
- Temporary Crown (if needed) – protects the tooth between visits
- Fitting the Final Restoration – crown or onlay bonded securely in place
Duration
- Typically requires two visits
- First appointment: prep and impressions (60–90 minutes)
- Second appointment: final fitting (30–45 minutes)
- In some cases, same-day crowns may be available with digital systems
Cost Factors
The price of crowns or onlays depends on:
- Material choice (porcelain, ceramic, zirconia, gold, or porcelain-fused-to-metal)
- Tooth location (molars often require stronger materials than front teeth)
- Complexity of the case (onlay vs. full crown)
Types of Crowns and Onlays
- Porcelain Crowns – natural-looking, ideal for front teeth
- Zirconia Crowns – extremely strong, suitable for front and back teeth
- Porcelain-Fused-to-Metal – durable but less natural in appearance under light
- Gold Crowns/Onlays – highly durable, though less common for visible teeth
- Composite/Resin Onlays – conservative option for smaller repairs
Ideal Patients
- Teeth weakened after large fillings
- Patients who have undergone root canal treatment
- Cracked, worn, or broken teeth
- Severe decay where fillings won’t last
- Anyone seeking both strength and a natural appearance
Patient Reviews
- “My tooth felt fragile, but the crown made it strong again.”
- “The onlay looked so natural, I can’t even see where the damage was.”
- “The process was smooth, and now I can chew without worry.”
Possible Side Effects
- Mild sensitivity or discomfort for a few days after fitting
- Crown may feel slightly high at first, easily adjusted by the dentist
- Rare cases of loosening or fracture, usually many years later
Benefits of Crowns and Onlays
- Protect teeth from further breakage
- Restore natural bite and chewing ability
- Blend seamlessly with surrounding teeth
- Provide long-lasting durability with proper care
- Reduce the risk of needing extractions or complex treatments
