Want to replace 8 upper and 6 lower porcelain veneers with eMax. Small hole developed, will this make removal more difficult?

Hello Amanda, in this case it is necessary to change the porcelain veneers for new ones.I do not recommend making patches in resin because it is not aesthetic.
I suggest removing them manually so as not to damage the teeth
