What Are Fillings, Inlays, and Onlays?
- Fillings: A filling is used to treat cavities or small areas of damage by restoring the tooth’s structure with materials like composite resin. This minimally invasive treatment stops decay from spreading and blends naturally with your tooth.
- Inlays: Inlays are custom-made restorations used for larger cavities or damage within the chewing surface of a tooth. They fit snugly within the grooves, providing precise and long-lasting repair.
- Onlays: Similar to inlays, onlays cover a larger area of the tooth, extending over one or more cusps. They are ideal for restoring teeth with extensive damage without the need for a full crown.
Benefits of Fillings, Inlays, and Onlays
- Natural Appearance: Modern materials like composite resin and ceramic mimic the colour and texture of natural teeth.
- Durability: Inlays and onlays are crafted from high-quality materials that resist wear and staining, offering long-lasting results.
- Preservation of Tooth Structure: These minimally invasive treatments repair damage while retaining as much of the natural tooth as possible.
- Custom Fit: Custom-made restorations ensure precise repair and optimal comfort.
- Enhanced Functionality: Restorations strengthen damaged teeth, improving your ability to chew and speak comfortably.

Risks & Recovery
Dental fillings are a routine way to restore teeth affected by decay or damage, but they come with some risks and recovery considerations.
Possible risks include:
- Temporary sensitivity to hot, cold or pressure after placement
- Gum irritation near the treated tooth
- Risk of filling fracture or wear over time
- Rare chance of needing further treatment, such as a crown or root canal, if the tooth is more compromised than expected
Recovery considerations:
- Most patients return to normal activities immediately
- Mild sensitivity usually settles within a few days
- Avoiding very hard or sticky foods can help protect new fillings
- Regular check-ups support long-term success of the restoration
