Unhappy with new crowns. Can I get a refund or try getting them redone? (Photos)

you have a wide smile, and a high lip smile, this treatments need to be done with someone experienced,you need to have a combined proceedure, gum contour,surgical, and also 10 veneers or crowns, that way your smile will look more nice and even.

Hi:It's is best to first express your concern to your dentist before contacting the insurance.Best,Dr. Maddahi

I always advise never agree to cementation unless you are happy with the esthetics.  
Esthetics are easy to correct prior to cementation.
Most dentists really want their patients happy and what you saw as rude was probably just a defensive response from your dentist.  He did not probably mean to be either rude or disrespectful but he may have been reacting to your tone.
Talk to a team member prior to your visit so she can "prime" the doctor for your visit.
That said, you are pulling your lip up in an unnatural position in photos with crowns compared to before photos.  The gummy smile is innate not from the crowns.  They crowns do appear opaque but the primary problem is that you did six teeth.  Ideally when improving a smile the rule is 4 teeth or 8, 10 teeth.  Six teeth almost always look unnatural if there is any color change, especially whitening.  
Ideally I would have started with a DNA Appliance to widen your narrow mouth and eliminate dark buccal corridors and create a full wide smile which makes an easier transition from canine to bicuspid.  OR do a 10 tooth case .  The shift from Canine to bicuspid looks bad.
Patients desire lowest cost crowns but dental lab costs can be as little as $50 for a crown to several hundreds of dollars.  I sometimes lose patients in my practice because "fees are high" but I pay high fees for lab work.  I would rather not do some work then have a less than desirable result.
