Dental composite are types of synthetic resins that are used in dentistry as restorative material or adhesives.
Direct dental composites are placed by the dentist in a clinical setting. Polymerization of a composite fillings is accomplished typically with a hand held curing light that emits specific wavelengths keyed to the initiator and catalyst packages involved. When using a curing light, the light should be held as close to the resin surface as possible, a shield should be placed between the light tip and the operator’s eyes.
Advantages of white fillings:
- A white filling can be matched to the colour of your surrounding tooth.
- White fillings don’t have the health risk posed by the mercury in amalgam fillings.
- Less post-treatment discomfort and sensitivity when using white composite fillings.
- Preparation of cavities for composite fillings can be minimally invasive
- In many cases of minor damage to a composite filling, the damage can be easily repaired by adding additional composite. An amalgam filling might require complete replacement.
- A composite filling usually requires only one visit
