Sherri Worth told me that my veneers would last 15 years, but then when the first one cracked at the gum line she claims veneers only last 2 years. She refused to replaced the cracked veneer. This is the 5th veneer that has cracked. I paid almost $40k and am having to replace each veneer. Do your research.
Sherri Worth is a hack. All of the reviews seem pretty similar to my experience. I've attached pictures of the veneers cracking at the gum line. Stay away.
