What are Veneers?
If there was a treatment to attain whiter teeth and better smile, it would be veneers. Dental veneers (also known as dental laminates) are thin, tooth-coloured shells. They are bonded to the surface of teeth to improve its appearance. They are similar to the contact lens worn on eyes. However, they cannot be removed everyday as it is bonded to the tooth structure permanently.
Types of Veneers:
Veneers are generally made of a variety of materials. They serve different purposes.
1) Porcelain veneers: It is the most commonly used high quality veneer that is used for a natural look. Porcelain veneers preserves the bulk of the original tooth structure and is a time-tested procedure. The procedure can be completed within 2-3 dental visits. Once the veneers are fabricated in the lab, they can be attached to the teeth with cement.
2) Ceramic veneers (Stacked and Pressed Ceramic): Ceramic veneers are relatively more aesthetic than porcelain veneers. The pressed ceramic veneers are thicker than the other type of veneers, and the stacked ceramic veneers are more aesthetically pleasing. The durability of ceramic veneers are less than porcelain veneers.
3) Lithium Disilicate: This type of veneers are newer. Due to its mechanical strength and durability, it is suitable for people with bruxism (tooth grinding). These veneers are created using computer aided technology.
4) Zirconia veneers: Zirconia based dental veneers are advised for those with structurally weak tooth. These veneers are popular for their property of fracture resistance. Also, zirconia provides very good aesthetics.
5) No-prep veneers: Unlike traditional veneers, these veneers do not need the tooth surface to be trimmed or prepped or require very minimal preparation. These veneers are adhesively bonded on the tooth structure. Patients undergoing a minimal preparation veneer procedure – such as for Lumineers, Durathin veneers and Vivaneeers – require no or minimal preparation of the teeth (mostly restricted to the enamel).
Composite Vs Porcelain veneers:
- Porcelain veneers mimic natural tooth structure efficiently as it reflects light just as the enamel of the teeth. Porcelain veneers do not get stained easily.
- Resin veneers are comparatively cheaper than the porcelain ones. However, they may get easily stained over time.
- Porcelain veneers can be prepared only in the lab and requires longer time for the completion of treatment. However, composite veneers can be prepared chair-side, thus, reducing the treatment time.
- Composite veneers must be polished to attain tooth-like finish. Whereas, the porcelain veneers do not require any polishing as they are fabricated to replicate the original tooth.
- Composite veneers can be removed, unlike porcelain veneers.
- Porcelain veneers can be used for almost all kinds of issues including genetic defects. Composite veneers cannot be used for severely discoloured teeth and spacing between the teeth.
Uses of Veneers:
Veneers play a major role in treating many aesthetic concerns such as discoloured teeth, chipped/broken teeth, uneven or irregularly shaped teeth. They can also be used for correcting the gap between the teeth or to change the shape of the teeth.
Smile design:
Smile design is a cosmetic dentistry concept. When perfect harmony is achieved between the facial components and dental components, perfect smile can be designed. The dentist considers various features of your face as well as dental structures (such as shape and size of the face and teeth, interpupillary line, dental midline and lips) while planning an aesthetic treatment. Any abnormalities in the facial components must be corrected before changing the dental components.
Veneers are also fabricated analysing these factors, keeping into account any personal preference of the patient. Veneers can be used to correct a single tooth or many. Six to eight teeth in the front are provided with veneers to change the colour and shape of the teeth to achieve symmetrical smile.
Diagnosis and treatment planning:
In the preliminary visit, the patient’s expectation from the treatment is discussed and the different options of veneers are discussed based on the requirement of the patient. Also, the patient’s oral health is assessed. The teeth that require veneers are checked for decay, gum issues, or if the patient requires orthodontic treatment.
Once such requirements are taken care of, the next stage involves fabrication of the veneers. In the next appointment, the teeth are cleaned, polished and trimmed. About half a millimetre of the teeth surface is reduced. The trimmed surface is then etched and the custom-made veneers are bonded with cement permanently.
Veneers are a very good alternative for crowns as it does not need extensive cutting of the original tooth structure. Also, the gum tissue easily tolerates veneers.
However, veneers cover the discoloured teeth and provide whiter teeth, improving the appearance of the smile.
Veneers are not advisable for the following:
- Patients with poor oral health, such as active gum issues or grossly decayed teeth may not be a good candidate for veneers.
- Fractured tooth, any tooth with large filling may also not provide the desired support for the veneers.
- Patients with very less enamel. Those with inadequate enamel may already have sensitivity issues. They would be better off without veneers as veneers may increase the sensitivity of the teeth.
- Patients with bruxism (those who clench/grind their teeth).
- Patients looking for temporary whitening of teeth. Veneers are an irreversible procedure. Once placed on the teeth, they cannot be removed.
How to care for veneers after the treatment?
- Follow the general oral hygiene practices. Brushing, flossing and using mouthwash can be continued as usual.
- Do not bite using your front teeth.
- Use only the back teeth for biting and chewing. Cut-up large bites of food to small ones to facilitate chewing only from the posterior teeth.
- Try to limit the consumption of foods that cause stains.
Longevity and Cost factor:
Dental veneers are not a permanent solution to improve the smile of a patient. Therefore, they usually last for about 10-15 years. Their cost varies based on the material of the veneer. Composite veneers are relatively inexpensive.
In conclusion, discuss with your dentist regarding the types of veneers available, your aesthetic concern and budget. Although veneers are known as “instant-orthodontics” and is an easier option to correct crooked teeth, it cannot be used to correct severe cases. Therefore, consultation with your dentist will help you decide the right treatment option.
