Composite filling in Shiraz


Composite filling is also known as white fillings. A composite filling is a synthetic type of material and made of glass and acrylic resins and is the same color as a tooth. Composite fillings look natural and can blend with the rest of the teeth. It is able to match the shade and texture of the natural teeth. Composite fillings last around 7 to 10 years, but in big majority of the cases composite fillings can last for a lifetime. Patients undergo composite fillings if they have 

  • Cavities
  • Chipped tooth
  • Wearing in the tooth

Porcelain or Composite

There are a number of pros and cons associated with both composite and porcelain, and amalgam.

Safety and Appearance: In addition to having a more pleasing and natural tooth-like appearance, porcelain and composite fillings have the potential advantage of not containing mercury or other metals that may contribute to sensitivity or toxicity. Mercury toxicity from amalgam fillings is a controversial subject, though no research to date has been able to show any risks of having mercury as a component of amalgam fillings. However, many patients do have metal sensitivities and some have reported a metal taste after the placement of amalgam.

Durability: Porcelain and composite previously were not as durable as amalgams. However, dental manufacturers have made great strides in improving the strength of composite resin materials, to the effect that composite fillings now have the potential to be used for all teeth, including molars. Furthermore, composite materials often require less tooth preparation and may not weaken the affected tooth as much as amalgam, which often require more extensive tooth preparation. However, amalgam fillings do have a long-term track record and may last longer than porcelain and composite.

Tooth Shaping: All fillings require preparation of the affected tooth, but less preparation is usually required for porcelain or composite. Typically, this means that less healthy tooth structure has to be removed when placing a composite.

Technique and Time: More than amalgam, the success of porcelain or composite depends on your dentist's technique. Porcelain or composite restorations also require the use of additional equipment, and the procedure itself requires up to 50 percent more time than the amalgam filling procedure. These factors contribute to the higher costs associated with porcelain and composites. In addition, most dental insurance companies do not cover the additional costs associated with porcelain and composite.

Skill: Most dentists are skilled in porcelain and composite fillings, but their level of skill may vary. Selecting the appropriate dentist is an important factor in treating tooth decay or similar damage. Ask if your dentist has obtained the kind of post-graduate education that allows dentists to refine their skills in porcelain or composite restorations.

If you spend some time understanding the differences between the various restorative procedures and the materials used for each, you will be better informed as to the option that works best for you. Consult with your dentist to determine the treatment time, cost, functionality and aesthetic value of all available restorative treatments for decayed or damaged teeth.


Dental filling background information

A dental filling is a type of restorative dentistry treatment used to repair minimal tooth fractures, tooth decay or otherwise damaged surfaces of the teeth. Filling materials, which include composite, porcelain and silver amalgam, may be used to even out tooth surfaces for better biting or chewing.

Enamel loss is a common component of tooth decay, and may result in tooth sensitivity. In many cases, sensitivity caused by enamel loss will be significantly improved or completely eliminated once an appropriate dental filling material is placed. But in some cases, depending on the extent of tooth decay or damage, the affected tooth may require additional or alternative procedures, including:

  • Dental Crowns: Teeth requiring more support than offered by a traditional filling may require a dental crown.
  • Dental Implants and Dental Bridges: Irreparable tooth damage requiring tooth extraction may require an implant or bridge.
  • Root Canals (perhaps along with antibiotic treatment): Infected, abscessed or nerve damaged teeth may require a root canal procedure.


What happens during a composite filling procedure?

The procedure will start by the dentist giving the patient local anesthetic to numb the area. A small dental drill will be used to remove the decay or any weak part of the tooth. Then the dentist will clean the tooth by blowing water and air onto the tooth. The tooth will be dried and then etched with a mild acid, which will help the filling material to firmly adhere to the tooth. The next step is for dental cement to be applied to coat the surface of the tooth before inserting the composite material. This will be pushed into the tooth cavity and then shaped as needed. Then the dentist will shine a bright light inside the mouth, which will activate and harden the material. Finally the tooth will be trimmed and polished for a new fresh finish.
