White fillings are indirect dental composites made from acrylic resin that comes in different tooth shades of whiteness and are artistically moulded as dental fillings for cavities in teeth.Direct dental composite may be used to restore small gaps in teeth. White fillings can also be used in reshaping teeth and in smile makeovers to enhance facial beauty.
A dental filling is any material that restores the normal shape and function of a tooth which has a portion missing due to decay or fracture. Most front teeth and some back teeth are filled with tooth-coloured material known as composite. It is made of plastic, quartz, and other fillers that give it strength and shine. Dental composite bonding is a popular choice for fillings because the material can match the shade, translucency and even the texture of your own natural teeth and provides a much better result than amalgam/silver fillings which can be unsightly when you smile.
A properly placed composite filling will last for years provided it is maintained with good oral hygiene and regular professional cleanings.
Composite is best used in small cavities. When it is used to fill back teeth in place of the more common silver amalgam fillings, it is less durable. When more than one-half of the tooth is missing, when some or all of the biting edge of a front tooth is missing, or when one of the cusps (points) of a back tooth is missing, a crown (cap) should be considered instead of composite. Crowns are stronger and will withstand greater chewing forces than composite. Experience has also shown that a small percentage of people will experience some hypersensitivity to this material, especially when it is used to fill back teeth. In these rare instances, removal of the composite filling and replacement with a different material may be necessary and additional costs may result.
White Fillings - The Positives
- The composite filling material contains only acrylic resin and glass particles, no mercury.
- The tooth coloured filling material matches your tooth colour for a natural finish
- This type of filling material is already hard when you leave the dental practice.
- Less tooth structure is lost because the dentist can make a smaller preparation
White Fillings - The NEGATIVES
- The composite filling material is more expensive
- Composite fillings can stain over a period of time depending factors such as tea, coffee and smoking
- These fillings do not get whiter if you bleach your teeth
- Composite fillings are strong on back teeth, but not as strong as amalgam
