Crown, Onlay, Filling – What’s the Difference and What’s the Right Choice for Me?

Crown, Onlay, Filling – What’s the Difference and What’s the Right Choice for Me?

30th July 2025

If you are thinking about investing in your dental health, you may have heard your dentist mention a crown, onlay or filling. But what exactly do these treatments mean – and which one is the best option for your tooth? 

We’ve put together this easy-to-follow guide to help you understand the differences and feel confident about your dental care choices.

What is a filling?

A filling is the simplest and most affordable option for repairing a tooth with a small cavity or minor damage. After the decayed area is removed, we restore the tooth with a durable material—often a tooth‑coloured composite that blends beautifully with your smile. Fillings are quick, effective, and usually completed in just one visit to the practice.

What is an onlay?

An onlay is a more advanced restoration, sometimes called a “partial crown.” It’s ideal when the tooth is too damaged for a filling but doesn’t yet need a full crown. Onlays are custom-made to fit your tooth precisely, helping to strengthen it while preserving as much natural structure as possible. For many East Devon patients, onlays provide an excellent balance of durability and conservation.

What is a crown?

A crown is a cap that covers the whole visible part of the tooth. This option is usually recommended when a tooth is cracked, heavily filled, or at risk of breaking further. Modern crowns are made from strong, natural-looking materials designed to match your smile. With the right care, they can last many years, making them a smart investment in both function and appearance.

Which option is right for me?

The choice between a filling, onlay, or crown depends on the extent of the damage to your tooth. At our Exmouth-based dental practice, we take the time to carefully assess your needs and explain your options clearly.

We believe that dental treatment isn’t just about repairing a tooth—it’s about investing in your long-term oral health, confidence, and overall wellbeing. By choosing the right treatment now, you can avoid bigger problems in the future and enjoy a strong, healthy smile for years to come.

Key Takeaway for Patients

• Fillings: Best for smaller repairs.

• Onlays: Ideal for moderate damage.

• Crowns: Recommended when the tooth needs full protection.
