What Happens Underneath Porcelain Veneers? Understanding Tooth Preparation

Porcelain veneers have become a popular option for individuals seeking to transform their smile. These thin, custom-made shells are bonded to the front surface of the teeth to improve their appearance. However, before the veneers can be attached, a crucial step called tooth preparation is required. Understanding the process of tooth preparation is essential to ensure successful and long-lasting results. In this blog, we will delve into the details of what happens underneath porcelain veneers, shedding light on the significance of this dental procedure.

The Importance of Tooth Preparation

Tooth preparation is a fundamental aspect of the porcelain veneer procedure and involves the careful reshaping and removal of a small portion of the tooth’s enamel. The purpose of tooth preparation is twofold: to create space for the veneers to be seamlessly placed and to ensure the longevity and stability of the restorations.

Step 1: Evaluation

Before commencing with tooth preparation, it is crucial for a dentist to conduct a thorough evaluation of the patient’s oral health. This typically includes an examination of the teeth, gums and bite, as well as any necessary X-rays or dental impressions.

Step 2: Designing the Veneers

Once the evaluation is complete, the dentist will work closely with the patient to design the veneers. This involves selecting the desired shape, size and color of the veneers to ensure a natural and aesthetically pleasing outcome. Communication between the patient and dentist is vital during this stage to achieve the desired results.

Step 3: Tooth Reshaping

Tooth preparation begins with the careful removal of a thin layer of enamel from the front surface of the teeth that will receive the veneers. This step ensures that the veneers can fit snugly without adding excessive bulk to the teeth. The dentist may use local anesthesia to minimize any discomfort during this process.

Step 4: Impressions

After the enamel reshaping is complete, impressions of the prepared teeth are taken. These impressions serve as a mold for the creation of the custom veneers. The impressions are sent to a dental laboratory, where skilled technicians fabricate the veneers according to the specifications provided by the dentist.

Step 5: Temporary Veneers

While you’re waiting for the permanent veneers to be fabricated, temporary veneers are typically placed on the prepared teeth. These temporary veneers offer protection and help maintain the appearance of the teeth until the final restorations are ready to be bonded.

Step 6: Veneer Bonding

Once the porcelain veneers are ready, the temporary veneers are removed, and the permanent ones are carefully cemented onto the prepared teeth. The dentist will ensure a perfect fit and make any necessary adjustments to achieve optimal aesthetics and functionality.

The Benefits of Tooth Preparation

As mentioned above, proper tooth preparation is essential for the success and longevity of porcelain veneers. But this process also helps you gain improved aesthetics and confidence from your new veneers.

Tooth preparation allows for better control over the final result, enabling the correction of various dental issues. Veneers can address concerns such as tooth discoloration, misalignment, gaps and chips, resulting in a naturally beautiful smile that enhances the your self-confidence.


Tooth preparation plays a vital role in the successful application of porcelain veneers. By carefully reshaping and removing a small portion of enamel, your dentist can create space for the veneers and ensure the long-term stability and aesthetics of the restorations.

If you’re considering porcelain veneers, consult with a qualified dentist to determine if tooth preparation is necessary and to ensure that you achieve the smile you’ve always dreamed of.
