1. What is porcelain veneer?
In essence, a porcelain veneer is a thin layer of material that is placed on the tooth to improve aesthetics and protect the tooth surface from damage. There are two main types of materials used to create veneers: composite and dental porcelain.
Composite veneers can be placed directly (integrated in the mouth) or fabricated indirectly by a dental technician in a laboratory and then bonded to the tooth with an adhesive resin. These types of veneers are often used in adolescent patients who will eventually need a more permanent design as adults. The average lifespan of a composite veneer is about four years.
In contrast, porcelain veneers (laminate veneers) can only be fabricated indirectly. They are restorations that cover the entire tooth surface. Laminate veneers are usually used for aesthetic purposes. They are less likely to retain plaque and are more effective and aesthetically pleasing.
2. What are the indications for porcelain veneers?
Porcelain veneer is a cosmetic dentistry can significantly improve a person’s appearance while solving many dental problems. However, not everyone is a suitable candidate for porcelain veneers and there are certain indications and contraindications for placing porcelain veneers.
So what are the indications for porcelain veneers?
2.1. Discolored teeth
Porcelain veneers are often used to address stained or discolored teeth, which can be caused by factors such as aging, medications, excessive fluoride intake, or certain foods and drinks. Teeth whitening is not always an effective solution, especially for deep stains, so porcelain veneers are a better alternative.
2.2. Deformed teeth
If a person has uneven or irregularly shaped teeth, porcelain veneers can help improve their appearance. They can be custom made to any shape or size to provide a more aesthetically pleasing look.
2.3. Enamel deficiency and reduced calcification
These conditions involve inadequate development or mineralization of tooth enamel. As a result, teeth may become discolored or more susceptible to decay. Porcelain veneers can be placed to protect teeth from further damage and improve their appearance.
2.4. Broken or chipped teeth
Chipped or broken teeth can be restored using porcelain veneers. They can cover the damaged area and provide a natural appearance, while preventing further damage to the tooth.
2.5. Teeth with gaps
Veneers can be used to close gaps between teeth. This is especially beneficial for people with small teeth, resulting in gaps that are difficult to close easily with orthodontics.
2.6. Worn teeth
Over time, teeth can become worn and appear shorter. This can lead to a prematurely aged appearance. Veneers can be used to lengthen these teeth, giving them a more youthful appearance.
2.7. Crooked or misaligned teeth
Veneers can be used as an alternative to orthodontics for people with crooked or misaligned teeth. They are often referred to as “instant orthodontics” because they can provide a straighter appearance in much less time than traditional braces.
It is important to note that the placement of porcelain veneers involves some degree of tooth preparation, which can lead to sensitivity or tooth decay if not done properly. Therefore, the placement of porcelain veneers should be limited to individuals with severe cosmetic concerns, such as severely cracked or broken teeth that are not candidates for crowns or complete replacement.
3. What are some contraindications of porcelain veneers?
While porcelain veneers can significantly enhance the aesthetics of a smile, they are not suitable for everyone. Placing veneers involves removing a small amount of tooth structure to accommodate the veneer, a process that is irreversible and can lead to sensitivity or tooth decay if not performed properly. Therefore, it is important to understand who is a good candidate for this treatment and when porcelain veneers may be contraindicated. Here are some of the main contraindications to veneer placement.
First, poor oral hygiene is a significant contraindication to veneers. Veneers require meticulous oral hygiene to maintain their appearance and prevent decay or gum disease from developing around the edges of the veneer. Therefore, people with poor oral hygiene or those who are not willing to engage in a comprehensive oral hygiene routine may not be good candidates for veneers.
Uncontrolled periodontal (gum) disease is another important contraindication. This is because porcelain veneers are bonded to the tooth and gum tissues, so any underlying gum disease can affect the bonding process and the long-term success of the procedure. Therefore, any existing gum disease must be treated and controlled before veneers can be placed.
People with a high rate of tooth decay or those who frequently need dental restorations are also not ideal candidates for the porcelain veneer procedure. This is because placing porcelain veneers involves removing some tooth structure, which can make the tooth more susceptible to decay. Additionally, if a tooth with a porcelain veneer develops decay, the entire veneer may need to be replaced.
Other conditions, such as teeth grinding, may also contraindicate veneers. The forces exerted on the teeth while grinding can cause veneers to chip or crack. While there are ways to control teeth grinding, such as wearing a night guard, people with severe teeth grinding may be better candidates for other dental restorations.
If the patient does not have enamel on the tooth surface, porcelain veneers may not be recommended. Veneers are typically bonded to the enamel layer. Without enamel, a strong bond is difficult to achieve, affecting the long-term success of the veneer.
Finally, the presence of large existing restorations may also contraindicate the placement of porcelain veneers. If a significant portion of the tooth has been replaced with a filling or other restoration, there may not be enough natural tooth structure left to support porcelain veneers. In these cases, other types of restorations, such as crowns, may be more appropriate.
