Dental veneers are microprostheses that are installed to restore the correct shape of teeth and improve their color. They are recommended when classical methods of whitening and removing defects have not brought positive results. The structures are practically no different from natural teeth. Unlike classic dentures, plates made of composite materials, ceramics and porcelain are strengthened only on the front surface of the teeth. Fixed prosthetics always require turning. Correct defects with veneers without grinding teeth. Is this really possible?
Veneers and teeth grinding are the main problems
With the help of veneers, aesthetic and functional problems are solved. They change the shape of teeth, eliminate unevenness in the enamel, hide yellowness and pigmentation, the presence of old fillings, external defects, and reduce large gaps between teeth. Installing veneers not only restores your smile to its lost beauty, but also rejuvenates your face.
Although the thickness of veneers ranges from 0.2 mm-0.5 mm, they are considered very reliable and have little wear. Thin plates must have a high density of contact with the tooth. This requires preliminary grinding. This procedure often becomes an insurmountable obstacle for patients who are candidates for veneers. How does the preparation process take place and does it really seriously harm the teeth?
Is it possible to restore a ground tooth after this?
Hard dental tissues, in particular enamel, do not have the ability to grow a new layer to replace the polished one. Otherwise, dentists would not put fillings, but would wait “until it heals on its own.” A ground tooth can only be restored with a new veneer or filling (direct restoration). If you refuse restoration and leave everything as is, then the remaining enamel will not look aesthetically pleasing - it will not have shine, and its protective functions (from caries, overheating and injuries) will be greatly reduced.

Is it possible to install veneers without turning?
In most situations, standard porcelain veneers cannot be installed without grinding. However, the use of modern technologies makes it possible to create veneers of smaller thickness, up to a maximum of 1 mm. Strong grinding exposes dentin, as a result of which porcelain adheres much less well. Minimal grinding allows you to preserve healthy enamel, on which veneers adhere much better.
The stitching procedure is not required in the following situations:
- with severe tooth wear;
- obvious unevenness of the cutting edge;
- incorrect position of teeth;
- with an initial lack of volume;
- if installation without stitching looks more aesthetically pleasing;
- crooked teeth.
In such cases, lumineers and ultraneers are recommended, which do not require preliminary tooth preparation. Their installation requires only minimal processing, which is carried out without anesthesia.
Nanoneers - what are they?
Nanoneers or nanoveneers are ordinary veneers that are created from a material with the addition of nanoparticles, due to which standard ceramics acquires different properties. Nanoneers are also created in Russian laboratories, but from materials and technology developed in Switzerland. As a rule, to fix nanoveneers, preparation of tooth enamel is not required, however, after installing them on the crown, the product is thoroughly polished and adjusted to the size of the tooth.
It should be noted that well-known manufacturers of ceramics for the manufacture of veneers are constantly improving technologies and adding particles to the ceramic mass that improve the mechanical and aesthetic properties of this type of microprosthesis. In particular, both e.max technology and feldspathic technology have their own similar secrets.
Disadvantages of installing plates without turning
Veneers without grinding have a number of disadvantages. These include: increased tooth thickness, which seriously affects aesthetics, the risk of serious problems during wear, and the impossibility of eliminating all defects.
In order for the veneers to adhere better, the surface of the enamel must first be etched with a special acid, as a result of which its appearance will be seriously and irreversibly changed. In the future, plates will definitely have to be installed on such teeth. The small thickness of lumineers cannot completely hide all shape defects.
Preliminary grinding ensures the creation of a smooth and high-quality transition into dental tissue. Installation without grinding provokes the formation of caries, plaque accumulation and gum inflammation.
How is turning for veneers carried out?
Turning is carried out in several stages:
- using a diamond bur, grooves are created in a transverse direction;
- the tooth surface is polished;
- the middle surfaces directed towards the adjacent teeth are ground down;
- the cutting edge is ground (from 0.5mm to 2mm);
- the palatal surface is worn away.
Finally, final processing is performed, during which sharp corners are rounded and protruding edges are eliminated. For comfortable installation of the plate, the protrusions are removed to the level of the arch, and the entire tooth is ground. This is necessary to ensure that the veneers and teeth are not damaged after installation.
The dental procedure is considered completely painless. The veneer is installed on the tooth without anesthesia or using modern analgesics. The plate is carefully glued to the surface, and the remaining glue is removed. As a result, the appearance of the teeth becomes ideal.

Types of veneers with minimal grinding of teeth
There are several types of veneers used as long as there is minimal tooth grinding. Composite veneers of high quality and aesthetics are manufactured in production conditions in order to be adapted in the clinic to the needs of a specific patient.
Ceramic plates allow you to get a highly aesthetic and durable result in one visit. Veneers are made in dental laboratories. To do this, an exact impression is first taken and a plaster model is cast, on the basis of which ceramic veneers are made.
How are veneers installed without grinding? First, the patient is asked to take a photograph of the jaw, then a computer simulation of the selected option occurs. After 2-3 weeks, a second appointment is scheduled to try on laboratory samples. The final installation of veneers is carried out after professional teeth cleaning.
Stages of prosthetics and their features
Prosthetics with aesthetic microprostheses includes the following stages:
- preparation: teeth are cleaned from stone and plaque, fillings are changed, the enamel layer is prepared,
- taking impressions: these can be either traditional impressions on impression material or digital impressions obtained by scanning the oral cavity with a 3D scanner,
- production of products in the laboratory: microprostheses can be manufactured using different methods - pressing, milling on a CAD/CAM system,
- fitting and fixation with temporary cement: this is a kind of “test drive” of a new smile, which lasts 1-2 weeks. This way a person can assess how comfortable he is and whether the designs need to be modified,
- fixation with a permanent adhesive composition.
Service price
Services for installing veneers with minimal grinding are provided by the best orthopedic dentists in Moscow. The cost of veneers with minimal grinding of teeth directly depends on the level of the clinic, the professionalism of the doctor and the selected material. This also includes the work of dental technicians and medical personnel.
The high cost is justified by the need for careful work to recreate the transparency of the enamel and its microrelief, the complexity of color transfer and restoration of the tooth structure.
Highly artistic veneers, invisible in the oral cavity, which look absolutely natural, cannot cost 30 thousand
rubles.
The price of such products starts from 50-60 thousand rubles. for one unit. Records made from aesthetic materials made in America will cost even more, however, they will last at least 15 years.
