Not feeling well after getting permanent veneers

Your symptoms sound like those of anemia or possibly a calorie deficient state.  This may be due to decreased food and drink consumption post your veneer procedure.  This is common and occurs when a person actually stops eating and/or drinking, due to a fear of damaging or staining there veneers.  I would suggest that you have the doctor evaluate your blood work to rule out anemia.I hope this helps.Dr. Sarah Thompson 

There are times when we place veneers that we need to place a special kind of string under the gums to help control bleeding and that can have epinephrine as an ingredient. Epinephrine (adrenalin) can cause a heart to race, but is a transient feeling. It typically does not remain afterwards. Other than that, I can't imagine anything related to your veneers that can cause your symptoms. 

Hi:I have not personally experienced this type of symptoms with veneers cementation.  Best,Dr. Maddahi

Sorry to hear about your health issues. I've been making veneers for over thirty years and have never had any complications similar to what you describe. Let us know how it works out and what your dentist recommends.
