All about veneers: marketing tricks, contraindications and service life

The first veneers appeared in the 1930s. They were developed by California dentist Charles Pinkus for Hollywood actresses and actors. Snow-white plates were attached to the teeth for close-up shots, and then they were removed. The temporary glue was so imperfect that the veneers fell out right during filming.

The demand for the service grew, and dentists realized that if they came up with a more reliable fixation, veneers would become popular among ordinary patients.

Doctors began experimenting with the adhesive. At first, non-removable veneers were attached to glass ionomer cements, and in the 1990s, modern adhesive fixation appeared. This is a certain order of application of dental materials, isolation of teeth to obtain a chemical bond between the tooth and ceramics and a method of gluing restorations on composite materials.

The adhesive fixation protocol provides a chemical bond between the tooth and the ceramic. They become a monolithic unit. The only way to remove the veneer is to cut it down. Therefore, this type of fixation increases the service life of ceramic restorations for decades.

Today, veneers made of three materials are most often found:

Ceramics surpasses other materials in terms of aesthetic properties and bonding reliability.

Composite materials are now considered the best solution for filling small lesions on the teeth. But not as an aesthetic veneer. For the first years, the composite veneer looks decent, but over time it changes in color. This is due to the porous structure of the material. Ceramics, unlike composite, do not change color for decades.

Zirconium veneers look good and do not change color. But since it is metal, it is impossible to carry out adhesive fixation to the tooth. It is necessary to glue the veneer, including on glass ionomer cement, which is not very durable.

The type of veneer is chosen by the doctor depending on the task at hand and the condition of the patient's teeth. For example, if there is a seal in the area of interdental contacts, the orthopedist puts a veneer that goes behind the contact points so that the filling material is under the veneer. If the tooth is healthy and even, and the patient wants to slightly change its shape or lighten it a little, the doctor will choose veneers that cover only the outer part of the tooth.

The thickness of veneers is on average from 0.2-0.3 mm to 0.5 mm. It also depends on the task facing the orthopedist. For example, if you need veneers that will change the color of the tooth by half a tone or by a tone, a thickness of 0.3-0.4 mm is enough. And when the patient's tooth is dark, a thicker layer of ceramics may be required.

Veneers cover the tooth from the visible side, so if it is badly destroyed, you will not be able to do with a veneer — you need a crown.

If the patient has a severely malocclusion, veneers are not put. First, you will have to grind the enamel hard and reach the dentin. Secondly, teeth in the wrong bite get an excessive load, and the veneer in this place can quickly chip off, since it will not withstand such pressure.

A relative contraindication to the installation of veneers is bruxism. This is the gnashing of teeth in a dream due to a spasm of the masticatory muscles. Frequent gnashing of teeth leads to rapid abrasion of the enamel. If you put ceramic veneers to a bruxist, he will also quickly erase them or chip them off. Therefore, a good orthopedist makes night protective caps for such patients.

There are no other contraindications. Veneers can be placed on a dead tooth if there is enough enamel. Patients often ask: will the veneer darken if a nerve is removed on the tooth under it. With the modern treatment protocol, the color of the tooth and the veneer will not change. The ceramic veneer itself does not change color, but it is so thin that the tooth shines through it. And if the color of the tooth itself has changed, then this will also be reflected on the veneer.

At the first visit, the orthopedist performs diagnostics: examines the teeth, takes photos, CT scans and scans the teeth. This is necessary to exclude hidden forms of inflammatory processes.

If the patient has pathologies, he is first referred to a specialized specialist. Before installing veneers, the patient must undergo professional oral hygiene. Restoration is not put on teeth with stones and plaque.

Then the orthopedist creates a 3D prototype of future veneers and at the second visit coordinates this form with the patient. As a rule, the prototype is shown in the form of a photograph: it is added to the portrait of the patient using a special program. Or doctors print a plastic model on a 3D printer and try it on to the patient.

The next stage is adjustments, if there are comments. The technician corrects the layout of the teeth, and it is shown to the patient. Then they grind the teeth under veneers, scan them and send the scan to a laboratory where ceramic restorations are made. Previously, doctors used prints, but with the advent of 3D scanners, this method has become obsolete. Thanks to digitalization, veneers for the entire jaw can be made in two days.

The penultimate stage is the fitting of finished veneers. If the patient is satisfied with everything, the restoration is fixed on the teeth on the same day. After that, the doctor conducts a control X-ray and checks if there is any excess of the fixing component. When the substance remains on the tissues, an inflammatory process can develop.

At the end, the orthopedist photographs the work and gives recommendations for the care of the veneer.

Hygiene is no different from the usual: you need to brush your teeth twice a day, use an irrigator, visit a hygienist every 3-4 months.

The veneer protects the area that it covers from caries. Therefore, quite often patients score on hygiene, knowing that there will be no caries under the veneer. But food gets under the gum, which borders the tooth. Plaque accumulates, and over time, caries may form.

Secondly, the veneer covers only the front part of the tooth, and the inner part remains unprotected. Caries is very rarely formed there, because the tongue is constantly in contact with this area and cleanses the tooth. But if you do not take care of your teeth at all, the tongue will not save you from caries. Therefore, the presence of veneers does not remove the responsibility for hygiene.

With proper oral care, veneers will last a lifetime. Unless, of course, you gnaw nuts right from the shell. But from such barbarism, the native tooth will also split. When a chip appears on the veneer, the doctor and the patient decide whether to polish the structure or, when the chip is large, replace it with a new veneer.

Over time, ceramics, as well as their own teeth, are erased. This is quite physiological: with age, changes occur in the temporomandibular joint, and with them the enamel is erased.

After a few years, the patient, if he is not satisfied with the aesthetics of the restoration, can consult a doctor for a reprosthetics.
