What is a veneer?
A veneer covers only the front surface of your tooth. They’re not as invasive as crowns, because the preparation leaves more of your original tooth intact.

About half a millimeter of the enamel on the front of the tooth is ground down to roughen the surface for bonding the veneer. Some newer types of veneers don’t need as much grinding of the tooth surface. You may need a local anesthetic for this, because the grinding may be painful.

What is a crown?
A crown covers the entire tooth. With a crown, more of the tooth needs to be filed or ground down to prepare for the crown placement.

If you have tooth decay, your dentist will remove the decayed part of the tooth before making the crown. In this case, your tooth may need to be built up to support the crown.

Pros and cons of veneers and crowns
Veneer pros
They may be more aesthetically pleasing than crowns in the long run, because they don’t show a gum margin after several years, as crowns sometimes do.
Some veneers don’t require a lot of trimming, so more of your healthy natural tooth remains.
Teeth with veneers have minimal movement.

Veneer cons
Veneers leave more areas of your tooth exposed to new decay.
Composite veneers cost less, but may only last 5–7 years. Other materials last longer, but may have to be replaced.
Veneers aren’t reversible.
Veneers may not be covered by dental insurance.

Crown pros
All of the tooth is covered, so your tooth is more protected from decay.
Porcelain crowns look and feel just like your natural teeth.
Crowns are relatively permanent and don’t have to be removed for cleaning as dentures do.
Dental insurance may cover a portion of the cost of a crown.

Crown cons
More of your natural tooth is removed to make room for the crown.
Your crowned tooth may be more sensitive to heat and cold initially and you may experience gum pain. If sensitivity increases, schedule a follow-up visit.
Porcelain is fragile and can be damaged over time.
Porcelain fused to a metal alloy (PFM) crown shows a thin dark line between your natural tooth and the crown.
