Dental Health and Veneers

Dental Health and Veneers

Dental veneers are thin, custom-made shells of tooth-coloured materials designed to cover the front surface of the teeth. Made from either porcelain or resin composite, these shells are then bonded to the front of the teeth changing their colour, shape, size, or length.

What Types of Problems Do Dental Veneers Fix?

·       Teeth that are discoloured - either because of root canal treatment; or staining.

·       Teeth that are worn down

·       Broken or chipped teeth

·       Misaligned, uneven, or irregularly shaped

·       Teeth with gaps between them

 

The Procedure

Getting a dental veneer usually requires three trips to the dentist – one for a consultation and two to make and apply the veneers.

 

·       Consultation and treatment planning

This first step involves talking to your dentist about your concerns and  the desired 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. X-rays and impressions of your mouth and teeth may also be taken.

 

·       Preparation

 To prepare a tooth for a veneer, your dentist will remove about 1/2 millimetre of enamel from the tooth surface. Next, your dentist will make a model or impressions of the teeth which will be sent out to a dental laboratory for construction. This process usually takes 1-2 weeks, though usually once teeth are filed down temporary veneers are given to the patient to ensure they can adjust their mouth to their new teeth in terms of everyday routines like eating, drinking and talking. Temporary veneers may cause a slight lisp but this resolves once the patient has worn them regularly.

 

·       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. They will then repeatedly remove and trim the veneer as needed to achieve the proper fit; and the veneer colour can be adjusted. To prepare the teeth for the veneer, your tooth will be cleaned, polished, and etched -- which roughens the tooth to allow for a strong bonding process. Once properly position on the tooth, your dentist will apply a special light beam to the dental veneer, which activates chemicals in the bonding material, causing it to harden. The final steps involve evaluating your bite and making any final adjustments in the veneer as necessary.

Advantages

·       Veneers provide a realistic tooth appearance

·       Gum tissue tolerates porcelain well.

·       Porcelain veneers are stain resistant.

·       Veneers offer a conservative approach to changing a tooth's colour and shape; no extensive shaping prior to the procedure like crowns.

·       Improves appearance in a relatively short period of time.

 

Disadvantages

·       The process is not reversible.

·       Veneers are a costly alternative to composite resin bonding.

·       Enamel removal may make teeth more sensitive

·       Teeth with veneers can still experience decay.

·       Veneers are not a good choice for patients with decay or gum disease, fractured teeth or those with large dental fillings.
