Dental veneers are used in a number of different cases. They may be used for patients with teeth that have become discoloured, worn away, chipped, broken, irregular, misaligned or unevenly spaced out.
They are also sometimes known as porcelain veneers. These porcelain veneers are wafer-thin and they are actually shells for the teeth; they are customized according to each patient’s teeth in terms of shape and colour. They are placed on the front part of the teeth in order to enhance their appearance. Cosmetic dental veneers may be used to change the length, shape, colour or size of the teeth.
In general, you will have to make at least three trips to your dentist if you want to get dental veneers. During the first appointment, your dentist will form their diagnosis and formulate a treatment plan. You will have to tell your dentist exactly the kind of look that you are after. The dentist will discuss what the procedure entails and any limitations that it may have. In addition to this, an x-ray or impression of your teeth may also be taken.
In the next session, the dentist will begin to prepare the teeth for the veneers. Approximately 0.5 millimetre of the enamel will be removed from the teeth, which is the same thickness as the veneer that will later be applied to the surface of each tooth. An anaesthesia may be administered to the patient at this point. After this, the dentist will make a model of each tooth. The model is then sent to the dental lab that creates the veneers, which is a process that can take up to two weeks.
In the third visit, the final process will be completed. Before the dentist permanently cements the veneer to the tooth, they will determine whether it fits properly and matches the colour of the teeth. Any alterations that are needed can be done at this time. For example, the veneer may be trimmed slightly so that it fits better. After that, the tooth is cleaned and polished and etched so that the rough surface can bond with the veneer as it is applied.
After the veneer is positioned on the teeth, it is hardened using a special light. This light activates the chemical found in the cementing agent and causes it to harden.
