First of all, this is just my personal opinion, it sounds like your dentist recommended extensive work for you. It may have been a good idea to get a second opinion before you had the work done, as a good dentist should offer the most conservative options. It seems like your dentist performed a great deal of dental work on you and I'm wondering if all of this was truly needed. Your headaches may very likely be coming from your dental work. I don't think that waiting another 3 or 4 weeks will resolve much as now it seems its been close to a year since your last procedure. It seems like thing should have settled by now. (I've had my own series of dental nightmares - although somewhat different than yours, so I know what you are going through). I completely understand that your social life and job are affected by this. You may want to seek a second opinion or try to find a specialist. A holistic dentist may be able to help. (Hopefully Bryanna reads this and can offer some advice on this). It may be that just one of the procedures is causing a problem, the problem would be to identify which one is the problem. It seems like your veneers are causing issues. I suggest trying to find a specialist. I've never heard of veneers protecting against root canals but I could be wrong. Many times you can get a consultation for free or for a nominal fee. Try to find a specialist who will work with you. I wish you all the best of luck! If you are in pain, keep trying to find someone who will help you, you don't have to live like that.
