What Are Cosmetic Fillings?
Cosmetic fillings, also known as tooth-coloured fillings, repair teeth affected by decay, minor damage, or wear. Unlike traditional silver fillings, they’re matched to the natural shade of your teeth, designed to blend naturally with your surrounding teeth. They can treat tooth decay, repair chipped teeth, restore worn tooth surfaces, and replace old fillings.
Benefits of Cosmetic Fillings
- Natural appearance, matched to your tooth colour
- Conservative treatment, removing only the damaged portion
- Strong, durable modern materials
- Usually completed in a single appointment

What Are Inlays and Onlays?
Sometimes a standard filling isn’t quite enough support, but a full crown isn’t necessary either. That’s where inlays and onlays come in.
Inlays
A custom-made restoration that fits within the grooves of a tooth, typically used when damage is too extensive for a filling but doesn’t affect the outer cusps.
VS
Onlays
Covers a larger area and may extend over one or more cusps, providing additional strength while preserving more natural tooth structure than a full crown.
When Are Inlays and Onlays
Recommended?
- Moderate tooth decay
- A failed existing filling
- A tooth weakened by damage
- Cracks or fractures
- Situations needing more strength than a standard filling provides

The Treatment Process
We assess the tooth and determine the most suitable restorative option, carefully remove any damaged or decayed tissue while preserving healthy structure, then take impressions or digital scans to create your custom restoration. A temporary restoration may be placed while the final piece is made, and once ready, it’s securely bonded and adjusted for comfort.
Cosmetic Fillings vs Inlays
and Onlays
Cosmetic fillings suit small to moderate cavities, minor repairs, and quick cosmetic improvements. Inlays and onlays suit larger areas of damage, weakened teeth, failed fillings, and situations needing longer-term reinforcement. We’ll explain which option is most appropriate for your tooth during your consultation.
