Veneer preparation is the step most patients want to understand before committing to treatment. You know veneers can change the appearance of your smile. But what does the dentist do to your teeth to make that happen?
This guide walks through the preparation process step by step, so you know what to expect at each appointment.
Before Preparation: The Planning Phase
Veneer preparation does not start on the day of the appointment. It starts weeks earlier with treatment planning.
At your initial consultation, your dentist will assess your teeth, gums, and bite. This typically involves:
- Digital scans or impressions of your upper and lower teeth
- Clinical photographs from multiple angles
- X-rays to check the health of the tooth roots and surrounding bone
- A conversation about your goals. What do you want to change? Colour, shape, alignment, size, or all of the above?
From this information, your dentist creates a treatment plan. At Ivy Dental, we use digital smile design to show you a preview of the planned result before any tooth preparation begins. This step lets you see the proposed shape and proportions and request adjustments before anything permanent happens.
In some cases, a diagnostic wax-up or digital mock-up is created so you can see the planned veneers in three dimensions. This is particularly useful for larger cases involving six or more teeth.
How Much Tooth Is Removed?
This is the question that causes the most concern, and it deserves a clear answer.
For traditional porcelain veneers, your dentist removes approximately 0.3 to 0.7 mm of enamel from the front (labial) surface of the tooth. For context, that is roughly the thickness of a fingernail, or about the same depth as a contact lens.
The amount removed depends on several factors:
- The desired colour change. Darker teeth require a slightly thicker veneer to mask the underlying shade, which means more enamel reduction.
- The desired shape change. If teeth need to be made wider or longer, less preparation may be needed because the veneer adds material rather than covering existing structure.
- Tooth position. Teeth that protrude may need more reduction so the veneer does not look bulky. Teeth that are set back may need minimal preparation.
- Enamel thickness. Thinner enamel limits how much can be removed while maintaining bond strength.
Your dentist should discuss the planned depth of preparation with you before starting. If you want to understand more about what affects your specific case, read our guide on what makes a veneer case higher risk.

The Preparation Appointment: Step by Step
Here is what happens during the preparation visit, typically the second or third appointment in the process.
Step 1: Anaesthesia. Local anaesthetic is administered to numb the teeth being prepared. This takes about 5 to 10 minutes to take full effect. You should not feel pain during the preparation.
Step 2: Enamel reduction. Using a fine diamond bur (a small rotating instrument), your dentist removes a controlled layer of enamel from the front surface of each tooth. Depth-control grooves are often placed first to ensure uniform reduction. Your dentist then reduces the enamel between these grooves to the planned depth.
The edges of the tooth are also refined. A slight margin is created at the gum line where the veneer will sit. The precision of this margin is critical for a good fit and long-term seal.
Step 3: Smoothing and checking. After initial preparation, the surfaces are smoothed. Your dentist checks the preparation with magnification, sometimes using a putty index made from the pre-treatment impression to verify that the correct amount of tooth has been removed in each area.
Records, shade selection, and temporary veneers
Step 4: Impressions or digital scans. A precise record of the prepared teeth is captured. At Ivy Dental, we use intraoral digital scanners for this step. The scan is sent directly to the ceramist who will fabricate your veneers. Digital scans are more accurate than traditional putty impressions and more comfortable for patients.
Step 5: Shade selection. Your dentist and the ceramist determine the target shade for your veneers. This may involve matching to adjacent natural teeth, or choosing a lighter shade if you are whitening the overall smile. Photos under standardised lighting are taken and sent to the lab.
Step 6: Temporary veneers. Provisional veneers are placed over the prepared teeth. These protect the exposed tooth structure, maintain appearance, and help you function normally while the permanent veneers are being made. Temporaries are made from acrylic or composite resin and are bonded with temporary cement so they can be removed at the next appointment.
Temporary veneers are not as strong or polished as the final product. They may feel slightly different against your tongue and lips. This is normal.
Between Appointments: Living with Temporaries
The period between preparation and final bonding is typically 2 to 3 weeks, depending on lab turnaround. During this time:
- Avoid biting directly into hard foods with your temporary veneers
- Do not pull sticky foods (caramel, chewing gum) across the front teeth
- Brush gently with a soft toothbrush
- Floss carefully, pulling the floss out sideways rather than snapping it upward, to avoid dislodging temporaries
- Contact your dentist if a temporary comes loose. This is not an emergency, but the tooth should be covered again promptly

The Bonding Appointment
At the final appointment, the temporary veneers are removed and the prepared teeth are cleaned thoroughly. The permanent veneers are tried in to check the fit, colour, and shape. This is your opportunity to see the result and confirm you are happy before permanent bonding.
Once approved, each veneer is bonded to the tooth using a dental adhesive and light-cured resin cement. The bonding process is technique-sensitive. The tooth surface is etched, primed, and the veneer is seated under controlled pressure. A curing light hardens the cement in seconds.
After bonding, excess cement is removed, the bite is checked and adjusted, and the margins are polished. You leave with your final veneers in place.
Porcelain vs Composite: Does Preparation Differ?
Yes. Composite veneers often require less tooth preparation than porcelain. In some cases, composite can be applied with minimal or no enamel removal. The trade-off is that composite is less durable, more prone to staining, and typically needs replacement sooner.
Porcelain veneers at Ivy Dental start from $1,200 per tooth. For a detailed comparison, see our guide on porcelain vs composite veneers.
What to Ask Your Dentist Before Preparation
Before committing to veneer preparation, make sure you have clear answers to:
- How much enamel will be removed from each tooth?
- Is a minimal-prep or no-prep option suitable for my case?
- Can I see a mock-up or digital preview before preparation starts?
- What happens if I am not happy with the final result?
- What is the warranty on the veneers?
- What is the total cost and are payment plans available?
