Mean Shaving for all types

Shaving teeth is one of the main steps in veneer installation, which helps to create enough space and better and more natural placement of the veneer. The amount of tooth grinding usually varies between 0.5 to 2 mm and its exact amount depends on the type of coating, the condition of the tooth and the skill of the dentist:

• Metal coating: About 0.5 to 1 mm grinding is enough (the least grinding).
• Zirconia coating: about 1 to 1.5 mm (less than normal ceramic due to high resistance).
• PFM coating (metal-ceramic): about 1.5 to 2 mm.
• All-ceramic coating: about 1.5 to 2 mm to create strength and beauty.

Tooth shaving is one of the main steps in preparing the tooth for installation of dental crown. The purpose of this process is to create enough space to place the crown, maintain proper contact with the adjacent teeth, and prevent protrusions or irregularities in the natural shape of the tooth. The point that should be noted is that the tooth sharpener should be enough to support the appropriate thickness of the veneer, but it should not be too much so as not to damage the pulp (dental nerve). In the following, we will discuss all the points of the amount of tooth grinding for veneer.

Factors affecting the amount of tooth grinding for veneers

In this process, the dentist tries to preserve the tooth enamel as much as possible and does not damage the dentin. Local anesthesia is usually used to reduce discomfort, but overall the pain is tolerable. After sharpening, the sensitivity of the teeth to heat or cold is normal and will disappear within a few days.

In addition to improving the fit and natural appearance of the veneer, tooth scraping prevents the accumulation of bacteria and tooth decay. However, excessive sharpening may cause problems such as severe sensitivity, gingivitis or even the need for nerve extraction.

Several important factors affect the amount and manner of tooth grinding:

• Type of cover: Ceramic covers need more thickness.
• Degree of tooth decay or damage: Damaged teeth may need more or less grinding to preserve the remaining structure.
• Teeth position: The front and back teeth are different, the front teeth are important for the beauty of a more precise cut and the back teeth are important for resistance to chewing pressure.
• Protective pulp shaving: In sensitive teeth, the dentist may prevent damage to the nerve by protective pulp shaving.
• Experience and skill of the dentist: Skill in precise grinding reduces the need for additional grinding and preserves the tooth structure.

The amount of tooth grinding is done to prepare the tooth so that the veneer can be installed well. Tooth grinding should be done enough to provide enough space for the veneer, but not too much so as not to damage the natural structure of the tooth and the pulp. In the following, we describe the amount of tooth grinding for all types of dental veneers:

Cutting rate of metal coating

Metal coating needs 0.5-1 mm cutting, because metal has a high resistance to chewing pressure and with a small thickness, it has a good performance. Less grinding preserves more of the natural tooth structure and reduces the risk of damage to the dental pulp. For this reason, this type of coating is suitable for back teeth that have high chewing pressure.

Cutting rate of PFM coating (metal-ceramic)

The amount of grinding required for this coating is about 1.5-2 mm to create enough space for the ceramic coating on the metal. This sharpening makes the coating, in addition to strength, have a natural appearance and the same color as other teeth. Also, proper grinding helps to maintain contact with the adjacent teeth and prevent protrusions or defects in the coating.

Cutting rate of all ceramic coating

For all-ceramic veneers, tooth grinding is done between 1.5 and 2 mm so that the ceramic has sufficient resistance to chewing pressure. A deeper cut helps create enough space for the thickness of the ceramic, resulting in a veneer that looks both strong and natural. Because of its beauty, this cover is mostly used for front teeth.

Cutting rate of zirconia coating

Zirconia coating needs a thickness of 1-1.5 mm. This material has a very high resistance. Therefore, it is possible to create a beautiful and strong coating with less grinding than normal ceramics. Proper grinding makes the tooth less damaged and guarantees a long life of the veneer. Also, precise installation of zirconia cover prevents decay and accumulation of bacteria around the tooth.

What is the reason for tooth grinding for veneers?

The purpose of the lathe is to create a suitable space for the exact installation of the coating. Reason for tooth grinding for coating; They consist of:

• Creating enough space for the veneer: Each type of veneer, depending on the material and thickness required, needs a certain space to be placed on the tooth. Proper cutting makes the coating not too prominent or uncomfortable when chewing.
• Maintaining the correct contact with the adjacent and opposite teeth: Tooth grinding accurately maintains the natural contact of the teeth with the side teeth and the opposite teeth and prevents bite problems.
• Increasing the durability and strength of the veneer: Proper sharpening optimizes the distribution of chewing pressure on the surface of the tooth and reduces the possibility of breakage or separation of the veneer.
• Preventing damage to the tooth pulp: Accurate and measured cutting, will not damage the healthy part of the tooth and the pulp, and after installing the veneer, the tooth will not suffer severe sensitivity.

Note: The amount of grinding for veneer is usually between 0.5 and 2 mm, which will be different depending on the type of veneer (metal, PFM, ceramic, zirconia).

Does it hurt to shave teeth for a veneer?

The tooth scraping for veneers is usually painless, because local anesthesia is used before the work begins. After the anesthesia wears off, the tooth may become a little sensitive to cold, heat, or the pressure of chewing, which usually decreases temporarily and within a few days, and maintaining oral hygiene and avoiding hard foods helps to reduce it.

Table of grinding amount for dental veneers

The tooth shaving is usually done in a conical shape so that the coating is well placed on the tooth and the contact with the adjacent teeth is maintained. In the following, we checked the amount of tooth grinding according to the important points:

Cover type Required cutting thickness Description Metal coating 0.5-1 mm Due to the high strength of the metal, low grinding is sufficient and the tooth structure is preserved. Metal-ceramic coating 1.5 to 2 mm It creates enough space for the ceramic on the metal and ensures the beauty and strength of the coating. All ceramic coating 1.5 to 2 mm For sufficient ceramic resistance and natural tooth appearance, deeper cutting is necessary. Zirconia cover 1 to 1. 5 mm The high resistance of zirconia makes it possible to make a strong and beautiful coating with less cutting.

Conclusion

Tooth shaving is a vital stage for veneers, which ensures the durability and beauty of veneers with the correct accuracy. The amount of sharpening depends on the type of coating, the position of the tooth, and the condition of the tooth, and it is very important to follow its principles.
