What Do You Need to Know Before Getting Veneers?
Modern dentistry gives the patients a unique opportunity to restore the smile line with the most innovative techniques. Malocclusion and an unaesthetic appearance of enamel can make a smile look unattractive. In case of minor defects, a correction method using veneers is applied. Veneers solve some dental problems, give confidence and a snow-white smile in just a few visits.
What Are Veneers?
Veneers are special ceramic onlays or plates that are attached to the outer surface of the enamel. Veneers help restoring teeth with tooth enamel defects and other problems with the teeth rows. Veneers are not the same as crowns as they cover only the front of the teeth. The primary function of veneers is to create an aesthetically pleasing smile line. However, they also solve other problems:
- straightening of slightly crooked teeth;
- uneven teeth;
- brown stains, yellow teeth;
- engrained plaque that is hard to remove;
- protect sensitive teeth from temperature or food exposure.
Veneers are placed in case of small interdental gaps, chips, and cracks, when teeth are of different lengths and shapes, in case of engrained plaque or hyperpigmentation resulting from internal organs systems’ pathologies. Answering why veneers are needed, it is essential to understand the main task of restoration activities. In fact, dentists now more often meet the patients without any particular dental problems but want to make their smiles more attractive.
How are Veneers Cemented on Teeth?
The veneers placement involves several main stages: the first consultation and examination of the oral cavity, preparation of teeth, preliminary fitting, final fixation of veneers, the types of veneers are selected.
The first appointment involves a doctor’s examination, full mouth debridement, tooth decay treatment, gum diseases, and other dental pathologies. One of the stages of debridgement is ultrasonic teeth cleaning. Sometimes it helps improve the smile appearance and lighten the enamel by almost 2-3 shades.
Manufacturing Process of Veneers
Digital impressions or Digital Smile Design technologies make it possible to model veneers considering the bite’s minor features and the maxillofacial structures’ anatomy. Due to computer technologies such as 3D scanners and digital software, the patients can see the final result before the restoration begins.
The shade and the shape of the new tooth are agreed upon with the patient before the correction starts. The color can be verified in daylight on the setup palettes. There are several basic methods for veneers manufacturing:
- Layering technique. Each layer is applied to a special foil that covers the patient’s tooth plaster cast. The porcelain mass is applied in thin layers to ensure maximum naturalness and transparency of the product. After the layers are applied, the model is fired in an oven and covered with a new layer. Then the patient tries the veneer on and, if necessary, it is adjusted.
- Composite veneers. For this purpose, the doctor takes casts from the teeth, and the plaster models are prepared. After that, the composite is exposed to ultraviolet light treatment. Subsequently, each plate is polished, ground, and sent for final placement. Adjustment is carried out if necessary.
- Injection moulding technique. It is used for porcelain veneers. The doctor takes an impression from each tooth, which is then used to make a wax-up, then it is filled with porcelain and fired in the oven. The wax is burned off, and a porcelain plate is obtained. The veneer is cleaned, polished, sanded, and is entirely ready for placement.
- 3D technologies. It is one of the most popular and innovative methods of making veneer models. The scanner reads information from a tooth prepared for restoration, calculates the plate’s necessary parameters, and grinds the finished model using special equipment. The main advantage is the reliability of calculations, high accuracy of results, and speed of production.
The Clinic of Aesthetic Dentistry uses the most innovative methods of veneers manufacturing. This saves the patient’s time and gives a snow-white smile in 1-2 visits.
Preparation of Oral Cavity
Veneers placement is impossible without preliminary preparation of the oral cavity. In addition to debridgement of cavities and treatment of gum diseases, the process involves preparing the teeth for onlays fixing. The outer surface needs to be faced to prepare the teeth. The facing area depends on the veneer type. Composite veneers require up to 0.8 mm reduction, porcelain plates – up to 0.3-0.4 mm. When installing lumineers, the thinnest ceramic onlays, it is enough to slightly face the enamel to create a rough surface.
Tooth facing is required to ensure reliable adhesion to the plate and maximize the final result’s aesthetics. If you do not grind it, the tooth will look abnormally large. In our Clinic, we use gentle teeth methods to preserve a larger volume of natural tissues.
Check-Up Impressions before Veneers Manufacturing
Check-up impressions after grinding the teeth are sent to the laboratory, where the final model is manufactured. Plastic temporary onlays are attached to the finished teeth to make patients feel comfortable expecting permanent veneers. Such plates protect the exposed tooth from temperature and food exposure, cavities and reduce the adaptation period after the permanent veneers are cemented.
Placement Phase – How the Onlays Are Attached
After veneers manufacturing, the doctor schedules the appointment. Temporary plates are removed, the oral cavity is treated with an antiseptic, plaque is removed if necessary, and the oral health is assessed. Permanent veneers are first cemented with temporary glue to evaluate the final result adequately, and if everything is in order, the onlays are fixed on a cement base.
After that, the veneers form a single whole with the natural tooth. The adaptation process depends on the bite’s characteristics, the number of restored teeth in a row. Usually, patients are so happy with the result that minor discomfort is almost invisible.
Thin plates are not fixed on all the teeth in a row. Usually, the onlays are attached to the front teeth along the smile line. The veneers on molars and premolars are impractical since thin plates cannot withstand the chewing load, unlike crowns or implants.
Dental Veneer Aftercare
The advantages of veneers are undeniable, as they quickly and efficiently solve the problem of teeth defects located in the smile line. Veneers can be bonded on 1-2 teeth or more. Before applying veneers, you need to grind your teeth. The facing process is irreversible, and the tissues are not restored. If the onlay breaks off, a crack has occurred on its surface, and then the entire product needs to be replaced. If it is impossible to place a new veneer, then the teeth need to be covered with a crown.
Usually, the veneering procedure is well tolerated and has no complications. However, some patients still experience some discomfort:
- sensitivity of enamel;
- gum irritation;
- gum bleeding.
These symptoms disappear after a few days. After the procedure, it is crucial to reconsider eating habits and avoid hard foods. It is necessary to avoid extremely cold or hot food in the first week, especially from sudden temperature changes, such as hot coffee after ice cream. Proper oral hygiene is essential. Patients should have professional teeth cleaning at least two times a year.
Placing veneers is an excellent solution for patients with an unaesthetic smile line. A variety of methods for correcting the dentition allows choosing the method that best suits your preferences and budget. After the aesthetic restoration procedure, it is essential to follow a number of medical recommendations to prolong the products’ life and prevent complications.
