What is the Difference Between a Porcelain Veneer and a 3/4 All Porcelain Crown?

Very smilar concept and preparation of the tooth. With Veneers you remove less tooth structure, but both options are porcelains. Your dentist is giving you the right guidance and doing the best treatment for your case. With new dental technology and products available, many options are provided to the patients to make long lasting beautiful smiles!

Veneers are a fantastic answer to a cosmetic problem, over the past 25 years I had the pleasure to place over 100,000 veneers.  3/4  crowns are almost the very same thing (aka PJC's in the old days).  Both work very well and if done properly can last decades.  Just ask most of Hollywood.  Cheers!

 Your dentist is on the right track in explaining to you the different treatment options based on your specific needs.  Most of the time, he or she will recommend what is best for the tooth in terms of strength and longevity.

There is not much difference between a porcelain veneer and a 3/4 crown,  The first one covers the front part of the tooth and often does not wrap around to the back or through the contacts between your teeth,  The 3/4 porcelain veneer will wrap around to the back of the tooth.  All porcelain crowns will cover the entire tooth.

I like the dentist approach to explain to you all the options for a great smile!

The difference bwtween veneer and 3/4 crown on the anterior teeth is absolutely minimal. You have been guided well. Remember that tooth preservation is as important as optimum result. A long lasting restoration many of times is better in the long run than having to sacrifice result for  preservation.

In your case he is doing the right thing.

The previous answers have covered the topic quite well. I would only add that the "line" that differentiates Veneers, 3/4 Crowns, etc, and blurred so much in recent years that I prefer to discuss them all as "Porcelain Restorations".  We even do thin veneers that wrap the entire tooth, fully restoring the lost tooth structure and improving the bite. Without the deeper tooth reduction of a full crown, I have a hard time calling this restoration anything but a "clamshell veneer".

For lack of a better description, only a dentist can tell the difference. The difference is nearly microscopic, so most patients should consider them equal. When restoring teeth, a well trained and ethical dentist will preserve as much tooth structure as possible, but not sacrifice the final result in efforts the be conservative.  It seems as if you have been given good advice. 

Dude to the technology of the materials we use today including cements, bonding agents and high-strength porcelain the difference there has been a paradigm shift in how we design and create restorations.  SO there is a continuum between a pure veneer and a full crown.  There are all sorts of intermediate forms of reiterations that may remove more tooth structure than a veneer, but less than a full crown.  An experienced dentist will try to preserve as much natural tooth structure as possible, while creating a long-lasting aesthetic restoration.
