What a couple of reasons one should opt for a crown over veneers?
What Are Two Main Differences Between Crowns and Porcelain Veneers?

The difference between crowns and veneers are:
The main difference is that a veneer covers the front of the tooth, and the biting edge. And sometimes it will cover between the teeth where the floss goes as well. It usually requires less tooth structure removal, unless the teooth has too much stain, or crack, or some damage. crown cover all of the tooth and the margin or edge of it come by the gum or under the gum all around.
Porcelain veneers, porcelain crowns
As the other dentists mentioned below, the use of porcelain veneers are more conservative than porcelain crowns. In fact, the new porcelains such as Emax allow for fabrication of porcelain veneers as thin as .3mm and still obtain excellent strength. These types of porcelains have definitely allowed me to be even more conservative than I was able to be in the past. If the teeth are not decayed and are healthy, most of the time the use of porcelain veneers will be a better choice.
There are often other considerations like your bite or TMJ problems that may need to be considered.

Porcelain Crown Vs. Porcelain Veneer
The difference between a porcelain crown and a porcelain veneer is in the amount of tooth structure that is removed for the restoration. A porcelain veneer only covers the front side of the tooth, while a crown covers the entire tooth. The materials that are used to make both are exactly the same. What constitutes which of these restorations would be correct to use? The simple answer is that we only use crowns when a good portion of the tooth has been compromised. Examples of this could be a tooth with a large amalgam filling, a broken tooth, or in people that are severe grinders. Veneers are the choice on front teeth if the tooth does not have any issues that are described above. Hope this helps.

Veneers are a better option than crowns, if POSSIBLE
Every dentist wants to do the least amount of damage to teeth necessary to achieve the desired goal. If enough tooth remains that a veneer can be done, it should be done.
Many dentists don't understand how bonding veneers to teeth work and feel more comfortable with the mechanics of a crown, but that does not mean a veneer is not possible or a good idea, it's just a limitation to the skill of the dental office.
A porcelain veneer is a porcelain shell 1/2 to 1 mm thick that covers the front and sides of a tooth. A crown simply covers the entire tooth. The can be made from the exact same material.
Crown vs. Veneer
A crown fully encases the tooth and requires removal of 1.5 mm of the tooth surface. A veneer is a thin shell bonded on the front surface of a tooth. Unlike the crown preparation, veneers require little tooth reduction and in some cases none at all. Veneers used to reshape teeth can be ultra-thin. Veneers used to hide discolorations of natural teeth need only be thick enough to mask out the area.
Both methods have gone through dramatic technical advancement to the point where personal preference is often the deciding factor.
Difference between crowns and veneers
The best way to desribe the difference between a crown and a veneer is that a crown covers the entire top of the tooth and a veneer just covers the front part of the tooth and leaves the inside part of the tooth untouched. This does not take into account all the variations of crowns, such as the materials used, if there is a metal base, etc. Also sometimes a veneer needs to cover more than just the facing of the tooth. There are times that a veneer may need to cover most of the tooth as well. In our office we don't really distinguish the difference with our all porcelain restorations, so as to avoid the confusion of semantics. One other difference is the veneer is ALWAYS bonded, where the crown can either be bonded or cemented.
Why do a crown instead of a veneer?
I think that most dentists would agree that if you had a choice as to whether to place a crown or a veneer on a front tooth, it would be better to place a veneer. Usually when a tooth needs a crown, there is no choice. So why would we recommend placing a crown?
Veneers are a very conservative treatment option. They are Great on teeth that are intact and pretty much whole. They haven't been compromised in their strength by large fillings. Veneers look beautiful.
Crown preparations are more agressive. Crowns cover the entire tooth and any fillings that are in the tooth. This is desirable if there are large fillings in the tooth that weaken the tooth or that might compromise the longterm success of a veneer. Some teeth fracture at the gumline and all that remains of them is their root. In these cases a root canal treatment, post build-up, and a crown would be the option. The new generation of crowns can look very beautiful as well.
What are the Differences Between Dental Crowns and Porcelain Veneers?
Crowns have been around for many decades. They have changed a lot and modern dental crowns have very high aesthetics and strength-but that hasn't always been the case. In the past many crowns displayed the "dreaded black line" at the gum line. You do not have to be concerned about that any more.
Veneers have now been around for decades too. The beauty of veneers just keeps getting better and better. Veneers are very versatile and also very strong. Under normal circumstances you don't need to worry about breaking a porcelain veneer any more than you would worry about breaking your tooth.
The main difference is that a veneer covers the front of the tooth, and the biting edge. Sometimes it will go in between the teeth as well. It typically does not go back too far on the back side of the tooth (where your tongue would touch it).
Some cosmetic dentistry patients NEED crowns because they have had too much damage to the existing tooth or the natural shade of the tooth is very dark. If you are highly prone to cavities you may be better off with dental crowns rather than veneers, until things improve.
Veneers work great for a smile makeover! They require less trimming of the teeth, so that leaves more of your natural tooth structure, which is more conservative. I have been involved with cosmetic dentistry in Denver for over 20 years-we are currently in an age where we are trying to be VERY conservative with what we do to your teeth.

Differences between veneers and crowns
The esthetics of a crown or a veneer are virtually the same. In the right hands both will look really good. The difference is that the crown wraps 360 degrees around the tooth. Thus, the crown provides more protection for a tooth that may have been weakened by significant decay or root canal treatment. The veneer is a good option for teeth that are discolored or misshapen but otherwise healthy. A veneer requires less tooth reduction. Usually the veneer covers the front “facial” portion of the tooth and extends to between the teeth.
