Many patients encounter terms such as "dental paste" and "dental veneer" when visiting a dentist to repair damaged teeth. Although these two treatment methods are used together, their roles and functions are different. A correct understanding of the difference between a dental post and veneer helps the patient make a more informed choice and go through the treatment process with peace of mind.

In this article from the dental website of Dr. Nazi Benianian, we will fully explain to you what a post is, what a veneer is, what are the differences between the two, when are they used, and how can the lifespan of each of these treatment methods be increased.

Introduction of a post and veneer Tooth

What is a dental post?

A dental post is a thin metallic or non-metallic rod (usually made of fiber or metal) that is inserted into the tooth canal after root canal therapy (nerve extraction). Its main purpose is to strengthen the tooth structure and create a solid base to hold the filling material and finally dental crowns.

The post is used when the tooth crown (the upper part that is visible) is severely damaged and there is not enough volume to support the restoration or crown.

What is a dental crown?

A crown is an artificial cap or covering that is placed on a tooth. The cover material can be one of ceramic cover, zirconia cover or a combination of metal and ceramic (pfm cover)

The main function of the veneer is to restore the appearance of the tooth, increase the beauty of the smile and protect the weakened tooth structure against fracture or chewing pressure.

Difference between post and veneer

Now let's go to the main topic: what is the difference between a post and a veneer?

So in simple words, a post is a "hidden column" that is placed inside the tooth to provide sufficient strength, and a crown is a "protective and aesthetic shield" that is installed on the tooth.

When do we need a post?

When the tooth crown is severely broken or decayed

Sometimes the dental crown is due to Deep tooth decay or a fracture caused by impact, is so damaged that there is no longer the ability to maintain a filling or veneer alone.

In such a situation, the remaining tooth structure is very weak and cannot withstand the pressures of chewing and biting.

In order for this tooth to continue to be preserved and the need for pull tooth, the dentist will place a post inside the root canal. This post acts like a pillar and helps to restore the crown of the tooth and create enough strength to be able to install a suitable veneer on it. Not enough to hold the filling material

In many cases, the tooth that needs nerve extraction has already suffered severe destruction due to caries. After removing the decayed tissues and performing root canal treatment, there may be a small amount of healthy tooth tissue left, which is not enough to hold the filling or veneer. The post is inserted into the canal and attached to the filling material and then to the veneer. This method makes the filling and cover firmly attached to the tooth and the risk of breaking or separating them is minimized.

In the back teeth that bear a lot of pressure when chewing

The back teeth or molars bear the most pressure when chewing food. If these teeth are severely damaged, even with tooth crowns, they may not be strong enough.

For this reason, in many cases, the dentist uses a post for the back teeth to create a strong base and the crown is placed on it more stably.

Otherwise, the crown may break or dislodge due to excessive pressure. get out The use of post in these areas greatly helps to increase the life of the treatment.

When do we need a cover?

Protecting denervated teeth

Next By performing root canal or root canal treatment, the internal structure of the tooth is weakened, and if left unprotected, the possibility of cracking or breaking is very high.

Nazi Benianian:

The dental crown with full crown coverage acts like a protective armor and evenly distributes the pressure caused by chewing and biting, thus preventing damage to the denervated tooth and significantly increasing its lifespan.

Cracked or broken teeth repair

Cracked or broken teeth cannot withstand the normal pressure of chewing due to structural weakness, and without protection they may have a more severe problem.

Using veneers, these teeth are strengthened and a protective layer is created on them that prevents the spread of cracks or fractures. In addition to maintaining the health of the teeth, this also prevents pain and subsequent problems.

Restore the beauty of the smile

In the front teeth that are exposed, Fractures, cracks or discoloration can greatly affect the beauty of your smile. Dental veneers give the teeth a natural and beautiful appearance and cover the defects. This solution is especially suitable for people who care about the beauty of their smile and increases confidence in speaking and laughing. Unifying the color and appearance of the teeth. They find heterogeneity. Dental crowns can even out the color and shape of the teeth and create a harmonious and beautiful smile.

This method is an ideal option especially for people who want a natural and integrated result, and it creates a sense of harmony and beauty in the entire mouth.

Are posts and crowns always used together?

No. If the tooth still has enough structure, the dentist will only use the crown. But in cases where the tooth is very damaged, first the post is placed inside the root and then the cover is installed on it. In fact, post and veneer complement each other.
