Porcelain veneers (dental laminates) are made of very thin slices of porcelain that are glazed with a very life-like lustre and appearance, they are custom-made. These tooth coloured materials designed to cover the front surface & or incisal tips of teeth to improve their colour, shape, size and length.
Dental veneers can be made from porcelain. Porcelain veneers resist stains better than resin veneers and better mimic the light reflecting properties of natural teeth. Resin veneers require removal of more of the tooth surface before placement. After a thorough examination, we will be able to discuss all possible options with you…
When are dental veneers needed?
- Teeth that are discoloured either because of root canaltreatment, stains from tetracycline or other 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
- Teeth that are malaligned, uneven, or irregularly shaped (for example, have craters or cracks or bulges in them, peg-shaped lateral)
- Teeth with gaps between them (to close the space between these teeth)
How are dental veneers done?
Getting a dental veneer usually requires two to three visits to the dentist – one for a consultation, treatment planning and two to do tooth preparation to receive the veneer and the third appointment to cement the veneers. One tooth or many teeth can simultaneously undergo the veneering process.
- Diagnosis and treatment planning: This first step involves your active participation. During this appointment, we 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. We may also take X-rays/photographs and possibly make impressions of your teeth. If required you can get wax mock-up to visualise the possible outcome (an additional appointment will be needed- may slightly increase the treatment cost).
- Preparation: Porcelain veneersare cemented to the outside surface of the teeth. In some cases where the face, lips and cheeks allow, the teeth do not need to be prepared (ground). In other cases, the teeth need to be slightly reduced, otherwise, the veneers can be too prominent. To prepare a tooth for a veneer, we will remove about 1/2 to 3/4 of a millimetre of the tooth surface, which is an amount nearly equal to the thickness of the veneer to be added. Next, the impression of your tooth is recorded to make a model. This model is sent out to a dental laboratory to fabricate ceramic veneer. It usually takes 1-2 weeks to receive the veneers. Temporary dental veneers will be placed on your prepared tooth until the time permanent ones arrive. In this appointment, you can decide or change the colour of the desired veneer.
- Bonding: we will temporarily place it on your tooth to examine its fit and colour. It may be necessary to repeatedly trim the veneer as needed to achieve the proper fit.at this stage the veneer colour can be minimally adjusted with the shade of cement to be used. (Not possible to change the colour after this appointment). Your tooth is prepared to receive the veneer, by cleaning, polishing and etching, this roughens the tooth to allow for a strong bonding process. A special resin cement is applied to the veneer positioned onto the tooth then cured with a special light beam. The final steps involve removing any excess cement, evaluating your bite and making any final adjustments in the veneer as necessary.
- We will ask you to return for a follow-up visit in a couple of weeks to check how your gums are responding to the presence of your veneer and to once again examine the veneer’s placement.
- At the end of treatment, a splint or night guard is often suggested to protect the new restorations from tooth grinding at night time.
Veneers offer the following advantages:
- They provide a natural tooth appearance.
- Gum tissue tolerates porcelain well.
- Porcelain veneers are stain resistant.
- The colour options and opacity nature of ceramic are better than any other material.
- Veneers offer a conservative approach to changing a tooth’s colour, shape and size. Veneers generally don’t require the extensive shaping prior to the procedure as crowns do, yet offer a stronger, more aesthetic alternative.
- Ceramic veneers are much stronger than composite/resin veneers
What are the limitations?
- The process is not reversible.
- Veneers are usually not repairable should they chip or crack.
- In very few instances, because enamel has been removed, your tooth may become more sensitive to hot and cold foods and beverages.
- Though not likely, veneers can dislodge and fall off. Which can be minimised by, not biting on, your nails, chew on pencils, ice, or other hard objects; or otherwise put excessive pressure on your teeth.
- Veneers are not a good choice for individuals with unhealthy teeth (for example, people with multiple decays or active gum disease), weakened teeth (as a result of decay, fracture, large dental fillings), or for those who have an inadequate amount of existing enamel on the tooth surface.
What’s the life expectancy of veneers?
Depending on how well you maintain and functional demands, veneers last for few years to lifetime. In many situations Veneers generally, last between 8 and 10 years. After this time, the veneers may need to be replaced.
Do Dental Veneers Require Special Care?
Dental veneers do not require any special care. Continue to follow good oral hygiene practices, including brushing and flossing as you normally would.
Even though porcelain veneers resist stains, your dentist may recommend that you avoid stain-causing foods and beverages (for example, coffee, tea, or red wine).
Alternatives to veneers include composite resin fillings or crowns. Veneers offer a nice intermediate option. Veneers may be best suited for individuals who want to change the shape of their teeth more than just a little bit, as is done with bonding, but not enough to require a crown.
The most common, conservative and cosmetic alternative to porcelain veneers is composite resin. Composite resin is a tooth-coloured filling material that may be used to form dental veneers.
Dental crowns may also be used to correct the same problems that dental veneers correct, however, it is a much less conservative procedure.
Composite veneers can be built up directly on to your teeth, with the boning technique. Composite is shaped and contoured to the front of your teeth and cured in a single visit. This type of veneer can offer similar appearance like that of porcelain. Veneers of composite material tend to be cheaper than porcelain as they are less durable and may be in need of replacement more often (lacks strength and often gets discoloured over years).
