Why Choose White Mercury Free Fillings?

Patients have several different options to have a cavity filled today. Among the choices including a tooth color restoration and the traditional amalgam restorations. Most people know amalgam a silver filling. Mercury makes up about 50% of the material. Composite on the other hand is a ceramic and plastic compound. Amalgam was a preferred choice of material for decades. With improvement of technology and material, composite is being iStock_000015891423XSmalloffered more by the dentists. Even though amalgam is still being offered as a material of choices, patients have options to avoid some of the disadvantages of silver restorations.

What is the cost of composites?

Aesthetics-can be matched to existing teeth color over the traditional silver filling material. Less healthy tooth structure removal because it chemically bonds to the cut tooth structure. Less costly as compared to dental crowns where white fillings can be given as an alternative option. White filling might not as durable as a crown but can be placed as a temporary restoration when financial restrictions play a role in patients’ decision for restoration. Composite fillings can save the tooth from being removed when the extent of decay may lead to severe loss of physical integrity. Composite fillings can be used to repair chipped, broken or worn teeth Composite can be easily repaired whereas an amalgam filling might require complete replacement. No mercury released into the environment and less exposure of mercury vapor to the patient and dentist Lack of corrosion: White restorations do not corrode at all as compared to amalgam.

Advantages of composites:

Composite shrinks and causes secondary caries- Shrinkage permits micro leakage, which, if not caught early, can cause secondary caries. This is the most significant dental disadvantage of this material. However shrinkage has a reduced by altering the composition of the resin. Among the newest materials, silorane resin exhibits lower polymerization shrinkage, compared to the dimethacrylates. Durability: when patient has large cavity composite fillings may not last as long as amalgam fillings. Chipping: Composite materials can chip off the tooth. Skill and training required: Successful outcomes in direct composite fillings is related to the skills of the practitioner and technique of placement. Need to keep working area in mouth completely dry: The prepared tooth must be completely dry (free of saliva and blood) when the resin material is being applied. This can be difficult to achieve in children. It does take a little longer to place the material as compared to amalgam. The fees can be higher due the chair time involved. Limited insurance coverage: Some dental insurance plans may provide reimbursement for composite restoration only on front teeth where amalgam restorations would be particularly objectionable on cosmetic grounds.
