A Primer on Veneers

Dental veneers are a transformative solution for individuals looking to enhance their smile. Veneers provide a relatively quick and effective way to address various dental imperfections. The choice between porcelain and composite resin veneers depends on the patient’s specific needs, preferences, and the advice of their dental professional.

A dental primer plays a pivotal role in the application process of veneers. Primers are used to prepare the tooth surface for the application of adhesives. The primer’s composition, often including hydrophilic (water-attracting) elements, enhances the bond strength between the tooth and the veneer, ensuring durability and longevity.

Self-etch adhesive systems streamline the veneer application process by combining etching and priming into one step. These systems use a self-etching primer that does not require the traditional separate etching step with phosphoric acid. This technique minimizes tooth sensitivity and preserves more of the tooth’s structure. Self-etch systems are known for their high bond strengths and compatibility with both dentin and enamel, the two main types of dental substrates involved in veneer applications.

The Importance of Tooth Dental Primers

The Importance of Tooth Dental Primers

A tooth veneer primer is a chemical agent applied to the tooth surface before the placement of a veneer. This primer is designed to improve the bond between the tooth’s surface—whether enamel or dentin—and the veneer material, which can be made from porcelain or composite resin. 

Primers often contain hydrophilic components that enhance the wettability of the tooth surface, creating a stronger bond. They are a critical component in both traditional and self-etch adhesive systems.

Enhancing the bond between the tooth and veneer is important to ensure durability and longevity. A strong bond extends the lifespan of veneers as it ensures that veneers can withstand the forces of biting and chewing. 

Securely bonded veneers also give a more natural appearance and prevent decay and sensitivity. It minimizes sensitivity by protecting the underlying tooth structure from external stimuli. 

Furthermore, the use of universal primers and self-etching primer systems ensures compatibility with a wide range of dental materials, including porcelain, zirconia, alumina, and composite resins. This versatility simplifies the veneer application process and broadens the treatment options available to patients.

How Dental Primers Work

How Dental Primers Work

Tooth veneer primers are formulated with a variety of chemical components to improve the interface between the dental substrate and the veneer. The composition typically includes monomers and solvents. 

Monomers are the primary components that interact with the tooth surface and bonding agent. Common monomers in dental primers include Bis-GMA (bisphenol A-glycidyl methacrylate), UDMA (urethane dimethacrylate), and HEMA (hydroxyethyl methacrylate). HEMA is particularly noted for its hydrophilic properties, improving wetting and penetration of the primer on the tooth surface.

In self-etching primers, acidic monomers are included to simultaneously etch and prime the tooth surface. These groups demineralize the superficial layer of the enamel or dentin, creating a micro-retentive surface for bonding.

Solvents such as water, ethanol, or acetone are used to facilitate the application and penetration of the primer into the tooth surface. They help in dispersing the primer evenly and evaporate after application, leaving the active components behind to interact with the tooth and adhesive.

The process of promoting adhesion through dental primers involves several chemical reactions and physical interactions. Etching is typically used for conventional systems. Traditional primers are used in conjunction with a separate etching step, where phosphoric acid is applied to the tooth surface to remove the smear layer and expose the enamel or dentin’s microstructure. This creates a rough surface for mechanical retention.

Self-etching primers are used for self-etch systems. These primers contain acidic monomers that simultaneously etch and prime the tooth surface. This simplifies the procedure by merging two steps into one, reducing the risk of over-etching and preserving more of the tooth structure.

The primer’s solvents and hydrophilic monomers improve the wetting of the dental surface, ensuring the primer spreads evenly and penetrates the microscopic irregularities of the etched or demineralized surface. After application, the solvent in the primer evaporates, concentrating the active monomers on the tooth surface.

The remaining monomers in the primer react with the bonding agent (applied after the primer) and the composite resin of the veneer. This reaction typically involves a light-curing step, where the bonding agent and the composite resin are hardened using a special light, creating a strong, durable bond.

The etched or demineralized surface of the tooth, along with the primer and bonding agent, creates a mechanical interlocking effect. This significantly enhances the retention of the veneer to the tooth.

The Application Process of Veneers with Dental Primers

The Application Process of Veneers with Dental Primers

The process of how veneers are put on is a meticulous one that involves several steps. The application of veneers starts with an initial consultation and planning where the dentist assesses the patient’s dental health, desired outcomes, and appropriate types of veneers.

Then, there is the preparation of the tooth surface by removing a small amount of enamel to accommodate the veneer. This involves precision to ensure enough space is created without compromising the tooth’s integrity.

After tooth preparation, the next step is the etching of the tooth surface. The dentist applies an etching solution (usually phosphoric acid) to create a rough surface on the tooth enamel or dentin for better mechanical retention. Then, the dentist goes ahead to select the appropriate dental primer based on the veneer material and the patient’s dental substrates.

After the primer has been applied (and the solvents have evaporated), there is the application of a bonding agent over the primer. This agent will further facilitate the adhesion between the tooth surface and the veneer.

The next step involves carefully placing the veneer onto the prepared tooth surface and making any necessary adjustments to ensure a perfect fit and natural appearance.

As a patient, you must maintain good oral hygiene and follow any pre-procedure instructions provided by the dentist. This includes avoiding certain foods or habits that might compromise the effectiveness of the veneer application. Post-procedure, you must adhere to oral care guidelines to ensure the longevity of your veneers, including regular check-ups, proper brushing, and flossing.

Potential Risks and Considerations of Dental Primers

Potential Risks and Considerations of Dental Primers

While the benefits of using dental primers are significant, it’s important to acknowledge some potential risks associated with this dental solution like allergic reactions. For example, some individuals may have sensitivities or allergies to components in dental primers, such as specific monomers (e.g., Bis-GMA, HEMA). Reactions can range from mild irritation to more severe allergic responses.

Furthermore, incorrect application of primers, or over-etching in the case of systems that require separate etching steps, can lead to increased tooth sensitivity. This is because the process can expose the dentin layer, which is more sensitive than the enamel.

Also, inadequate application of primer or its improper integration with other components (bonding agents, composite resins) can lead to bond failure, resulting in the detachment of the restoration or the need for reapplication. Although rare, accidental spillage of primer on the soft tissues of the mouth can cause chemical burns or irritation due to the acidic nature of some priming agents.

To mitigate these risks, dentists conduct thorough assessments, including medical and dental history reviews, to identify any potential allergies or sensitivities to materials commonly used in dental treatments. There should also be more consciousness put into precise application techniques and the use of advanced materials. 

In addition, dentists should educate patients on what to expect during and after the application of primers and restorations. This includes providing information on potential side effects and how to manage them, ensuring patients are well-informed and can participate in their care.

Bedford Dental Groups Celebrity Veneers

Bedford Dental Groups Celebrity Veneers

There are 5 different types of veneers currently available:

1. Porcelain

Bedford Dental Group specializes in Porcelain Veneers (also known as traditional veneers), which are the most dependable and have been around the longest. Dentists began using porcelain veneers in the 1930’s. When being fitted with porcelain veneers, your dentist will remove a thin layer of enamel from the front of the tooth before permanently affixing the veneer. With proper care, these veneers can last 20 years.

2. Lumineers

Lumineers are the thinnest option when it comes to dental veneers — about as thick as a contact lens. Applying Lumineers does not require grinding and is pain-free for the patient. Common complaints include lumineers becoming detached, dark natural teeth casting a shadow through the thin Lumineer surface, and dissatisfaction with the thickness of the Lumineer.

3. Composite

Composite veneers (also known as bonded veneers) are a less-expensive option that does not require any grinding or reshaping of your natural teeth. They typically last five to ten years with proper care — but they can be prone to chipping and staining. The upside is that they are easy to fix.

4. Zirconia

Zirconia porcelain veneers are ideal for patients who have teeth that are more severely damaged or decayed. The material is stronger than traditional porcelain and is appropriate for patients who need additional reinforcement of their natural teeth. Zirconia veneers are also able to withstand more wear and tear, making them appropriate for use on back teeth.

5. CEREC © Veneers

The CEREC® (Chairside Economical Restoration of Esthetic Ceramics) system allows your dentist to design and create custom veneers in-office, eliminating the need for a second appointment. They are a quick and convenient option for patients looking for an easy smile-transformation process.
The cost of dental veneers varies and patients being fitted with dental veneers should be ready to pay for this cosmetic procedure out-of-pocket. Most patients who have changed their smile with veneers consider the procedure more than a worthwhile investment. That is why it is important to educate yourself on the options and make a choice that fits with your goals and budget.
