Fillings are a standard part of dentistry, most people will have at some point had a filling and with modern dentistry they are quick and pain free.
Fillings are used to restore a tooth back to its regular function and shape caused by carries in the tooth (decay) or from trauma to the tooth such as a trip or fall.
What types of filling we do ?
Composite or white fillings
Composite fillings are the most popular fillings in these days because of their excellent natural appearance and strength. Their durability is now comparable to amalgam fillings. The shade of composite filling material is selected to match the colour of your teeth as closely as possible..
- Cosmetic appearance.
• May bond a weak tooth together, reducing the risk of fracture in an extensively filled tooth.
• Can be fitted into very small holes, so less drilling is needed in preparation for the filling.
- Composite fillings take longer to place than amalgam fillings..
• Not a good choice for patients with high caries rates.
• Increased sensitivity in some cases.
Dental amalgam has been around for more than 150 years. A small to moderate-sized amalgam filling can last many years before it wears out and requires replacement. Dental amalgam is made up of silver, tin, copper and mercury. The American, Australian and New Zealand Dental Associations report that amalgam fillings are safe for patients. .
- Strong, long lasting, proven material.
• Low cost.
• Material seals itself into the preparation, inhibiting recurrent decay.
- It is not tooth-coloured.
• It does not bind the tooth together.
• More tooth structure may have to be removed to get the amalgam to stay in the tooth.
• Contains mercury in trace amounts.
The advantage of gold fillings is their strength and durability, although they are more expensive than other filling types.
Glass ionomer cement fillings
Glass ionomer is a tooth-coloured material, typically used as a durable temporary filling, or as a foundation underneath fillings made of composite.
Porcelain inlays or onlays
Porcelain is a ceramic material that is matched to the tooth colour to provide a cosmetic result. It is a material designed for use on back teeth, and is glued into the tooth cavity with a special, powerful glue that increases the strength of the bond. The porcelain filling is extremely strong and wear resistant. It can last indefinitely, provided you do not get a new cavity underneath it, or abuse your teeth.
- Very strong.
• A cosmetic tooth-coloured alternative.
• Long service life.
• Fillings generally weaken teeth, but because inlays are bonded to the tooth, they can offset this weakening to some degree.
- Inlays are the most expensive of the filling materials.
Gold inlays or onlays
The advantages of these restorations are similar to porcelain inlays or onlays with their excellent strength and durability. They are more expensive than other filling types.
On your visit to bright smile dental, the location and extent of the decay, cost of filling material and dentist’s recommendation will help in determining the type of filling best for you.
