Root canal, had veneers remade already, not happy with second set. Can I ask for them to be remade? Will this damage teeth?

Summary of procedures: - Temporaries for 6 weeks - First set of veneers cemented, spaces between teeth which I didn’t like - First set removed, in temporaries for another 3 weeks - Second set cemented but before I got a chance to adjust to them and decide if I was happy had to get root canal on one tooth - Now have same symptoms in another tooth I am not happy with my veneers and would like to get them changed however am concerned about further damaging teeth, what should I do?
