DENTAL VENEERS

Dental Veneers (sometimes called porcelain veneers or dental porcelain laminates) are wafer-thin, custom-made shells of tooth -coloured materials designed to cover the front surface of the teeth to improve your appearance. These shells are bonded to the front of the teeth changing their colour, shape, size, or length.

Dental veneers can be made from porcelain or from resin composite materials. Porcelain veneers resist stains better than resin veneers and better mimic the light reflecting properties of natural teeth. You will need to discuss the best choice of veneer material for you with your dentist.

Dental Veneers are applied for cosmetic reasons, more precisely, for the following reasons;

Teeth that are discoloured — either because of root canal treatment; stains from tea coffee or prescription drugs, excessive fluoride or other causes; or the presence of large resin fillings that have discoloured the tooth.

  • Teeth that are worn down.
  • Teeth that are chipped or broken.
  • When teeth are misaligned, uneven, or irregularly shaped.
  • Teeth with gaps between them (to close the space between these teeth).

The procedure for fitting dental veneers is as follows;

Getting a set of dental veneers usually requires at least two trips to the dentist, one for a consultation and at least one to apply the veneers. One tooth or many teeth can simultaneously undergo the veneering process described below.

  • Diagnosis and treatment planning. This first step involves your active participation. Explain to your dentist the result that you are trying to achieve. During this appointment, your dentist will examine your teeth to make sure dental veneers are appropriate for you and discuss what the procedure will involve and some of its limitations. He or she also may take X-rays and possibly make impressions of your mouth and teeth.

 

  • Preparation. To prepare a tooth for a veneer, your dentist will remove about 1/2 millimetre of enamel from the tooth surface, which is an amount nearly equal to the thickness of the veneer to be added to the tooth surface. Before trimming off the enamel, you and your dentist will decide the need for a local anaesthetic to numb the area. Next, your dentist will make a model or impression of your tooth. This model will be passed to our dental laboratory, which in turn constructs your veneers. It takes 1 week for us to receive the veneers back from the laboratory. For very unsightly teeth, temporary dental veneers can be placed.
  • Bonding . Before the dental veneer is permanently cemented to your tooth, your dentist will temporarily place it on your tooth to examine its fit and colour. He or she will repeatedly remove and trim the veneer as needed to achieve the proper fit; the veneer colour can be adjusted with the shade of cement to be used. Next, to prepare your tooth to receive the veneer, your tooth will be cleaned, polished, and etched. Etching roughens the tooth to allow for a strong bonding process. Then, a special cement is applied to the veneer and the veneer is then placed on your tooth. Once properly position on the tooth, your dentist will apply a special light beam to the dental veneer, which activates chemicals in the cement, causing it to harden or cure very quickly. The final steps involve removing any excess cement, evaluating your bite and making any final adjustments in the veneer/s as necessary.
