How should I tell my dentist that I’m not happy with my composite veneers?

I always encourage my patients to be interactive, to voice their concerns or to give me any feedback  they may have.  At the end of the day, we want to meet our patients' expectations and for them to be happy.  I would definitely follow up with your dentist and ask him/her to make any necessary changes, adjustments or repairs, and discuss other possible alternatives if you are not happy.  Good luck!

You should definitely speak with your dentist about your concerns. It could be that they did the best they possibly could. Or you may be able to have them adjusted slightly. 

Communications between doctors and patients are critical and essential. If you don’t like something especially cosmetically related, you need to speak up. The longer you wait, the lesser the chance you’ll have a stand against the issue. Call your dentist today. 

As a patient you certainly should communicate directly with your doctor and discuss how your concern can be addressed. It may be the case that lab fabricated porcelain veneers may be the way to go for you in order to get a more ideal result. There is nothing with being honest and forthright with your treating doctor. The work has already been performed and the time spent, as such, you may have to absorb that cost, but one solution you can suggest to your doctor is whether they would consider crediting the cost of the composite veneers towards your new porcelain lab veneers in order to help you out, it's a win-win situation if your doctor agrees to this arrangement. Good luck!
