Need Veneers for All Four Front Teeth or Just the Two with Chips?

If you are hiring an experienced cosmetic dentist for the job, here are some things he/she may be considering. First if there is currently any asymmetry in your front 4 teeth, and you go and make the front 2 teeth symmetrical (which you will with your veneers) - you will amplify the asymmetry remaining in the 2 side teeth. Also, if your front 2 teeth are currently larger or have any spaces, these teeth may end up looking too large without doing the side 2 teeth. If your side teeth are symmetrical, proportional, and the color you want them to be...and the front two teeth are proportional in your smile, you may be able to get away with just doing 2. You may end up with several more visits as you try to get a perfect shade match if you only do the 2 front teeth.

"Happier", is all in the eyes of the beholder. If you feel the 2 veneers are all that are needed then do 2. Understand that by doing 4 you will be able to create a much better color and shape transitions for your smile.
In our office, we offer our patients a simple procedure called a mockup. It's easy and just takes a few minutes. Mockup is our vision of the patients new smile, taking any objections of the patent into consideration. We work with a patient as a team to reach one's goals. This helps most patients in choosing which route to go. Maybe you can ask your dentist to show you the other 2 teeth to see what it will actually do to your smile!
Hope this helps.
