At Noosa Family Dental we are an amalgam (silver/mercury) free practice.
Why composite resin fillings?
Tooth coloured fillings are our preference for a number or reasons:
- Conservation of natural tooth: Tooth coloured fillings require less of the precious tooth to be removed. They are bonded in, allowing them to actually support and reinforce the tooth.
- Natural appearance: They look great! There have been incredible advancements in resin technology over the passed 20 years. We now have excellent shade selection and colour stability.
- Strong: These materials, if designed correctly, can rival porcelain longevity. They are strong enough to protect back teeth, and restore front teeth.
- Quick: Composite resin is placed on the spot, there is no need for multiple appointments.
- Repairable: Unlike porcelain, resin can often be repaired if there is local degradation. This is a cost effective strategy.
What is composite resin used for?
Composite resin is a very adaptable material which can be used throughout the mouth.
On back teeth we use it to:
- Repair breakages
- Restore areas lost due to decay
- Protect teeth from crack penetration
- Close annoying gaps which trap food
On front teeth we use it to:
- Change the shape, size and appearance of the teeth
- Cover stains
- Close gaps
- Make teeth appear straighter
- Restore breakages
- Restore areas lost due to decay.
The dentist will need to prepare the surface of the tooth and clean it thoroughly. A couple of tooth preparation liquids are placed. The resin is then placed and moulded in thin layers, each layer is set with a blue light. The blue light makes the resin hard. The bite is checked and adjusted and the filling polished until it is very smooth. Local anaesthetic is not always necessary.
