You've seen the before and after photographs. Porcelain veneers can transform teeth that are chipped, stained, slightly crooked, or uneven — sometimes in just two appointments. The results are dramatic.

But there are things about the process that dental advertisements don't always make clear. What actually happens to your natural teeth? Is it reversible? What can go wrong?

Here is an honest account of what porcelain veneers actually involve.

A veneer is a thin shell of porcelain — typically 0.3 to 0.7 millimetres thick — bonded to the front surface of a tooth. It is custom-made to fit your tooth and to match the colour and shape of your surrounding teeth.

Veneers are considered a permanent alteration because the underlying tooth is permanently prepared — a thin layer of enamel is removed to make room for the veneer. This cannot be undone.

1. Consultation and planning. Your dentist assesses your teeth, discusses what you want to achieve, and may show you a digital mock-up or wax-up of the proposed result. This stage is critical — your expectations and the clinical possibilities need to align.

2. Tooth preparation. A thin layer of enamel — generally 0.3 to 0.7mm — is removed from the front of the tooth. Local anaesthetic is used. The amount removed depends on the case: if your teeth are already slightly protruding, you may need more reduction; if they're naturally small or worn, less.

3. Impressions. Your dentist takes an impression or digital scan of your prepared teeth. This is sent to a dental technician who constructs your custom veneers — usually taking 1 to 2 weeks.

4. Temporary veneers. Your dentist may place temporary composite veneers to protect the prepared teeth while your permanent ones are being made. Not all dentists do this in all cases.

5. Fitting. Your dentist tries the veneer on, checks the fit and colour, and makes any necessary adjustments. The tooth is cleaned and etched. A bonding cement is placed, and the veneer is positioned and cured with a blue light to set the cement.

Porcelain veneers typically last 10 to 15 years. Some last 20 years with excellent care. The bonding cement is the weak point — over many years, veneers can debond, chip, or crack.

Once a veneer is placed, it is not maintenance-free. The tooth beneath it is still vulnerable to decay at the margin — the edge where the veneer meets the tooth. Gum recession can also expose the edge of the veneer over time.

Porcelain is highly resistant to staining, but the bonding margin can discolour. And composite repairs to a chipped veneer do not match porcelain in appearance or durability.

Like any dental procedure, veneers carry risks:

• Sensitivity. Removing enamel exposes the dentin. Many patients experience increased temperature sensitivity after preparation. This usually settles but can persist.
• Chip or fracture. Porcelain is strong but not unbreakable. Biting on very hard objects, ice, or fingernails can crack a veneer.
• Colour mismatch. Getting the exact shade and translucency to match your natural teeth — or your desired whiteness — requires skill. Poorly matched veneers are noticeable.
• Irreversibility. The enamel removed is gone forever. If a veneer fails and needs replacing, the underlying tooth always needs a new veneer or crown. You cannot undo the procedure.

Veneers are most appropriate when:

• Teeth are discoloured — from tetracycline, fluorosis, root canal treatment, or large fillings
• Teeth are chipped or worn
• Gaps between front teeth need closing
• Teeth are slightly misaligned or uneven in shape

Veneers are not appropriate when:

• Teeth have active gum disease or significant decay — the underlying issues must be treated first
• Teeth are heavily ground — a crown may be more appropriate
• Patients have a habit of biting hard objects — veneers will fracture
• The patient is looking for a dramatic change without understanding the maintenance commitment

Veneers can give you the smile you've wanted — but only if they're the right treatment for your specific situation. A good dentist will tell you if veneers are not appropriate for you, even if that's not what you came in hoping to hear.
