Hello Scaredmama ......
First I think you're doing everything you should be doing. If he meant he wants to take a few days away from everyone ... that's not a good idea. If he meant he wants to take a few days off of work - and be around home to think, meditate or whatever. With the assistance of some medication, that sounds like a very good idea. It is a time of reflection for him. It is probably a scary time for him - not just for what may happen in the future, but for what is going to happen on the next dentist visit.
I went thru something very similar years ago. I went to a peridontist and after his examination and our consultation, I asked him "how long will my teeth likely be saved by theperidontal work"? My work insurance did NOT cover it. The dentist gave his predictably non-committal "well, there's no guarantee"!
So on that basis, plus it being completely out of our own pocket for costs, I told him I can't move ahead with the peridontal surgery. So ... the option was partials on top and bottom ... and a lot of teeth pulled.
I was 40 at the time ... and I had 14-teeth pulled in one sitting - and then the partial impressions made - all on the same day. It was a three hour session in the chair. And I have to tell you, that morning at work I was a complete basket case. In fact, it was the first and only time I have ever used breathing into a paper bag to fight the anxiety.
It was a memorable experience.
To make it worse, my wife didn't even go with me to the dentist. I drove there alone ... sat in the chair for three hours ... and shortly after drove back home alone. It was only about 3-miles to the dentist and the only med used during the extractions was novacaine.
Trust me ............. he needs your continued support ... and he needs some help to control the anxiety. If he has to take three days off of work - so be it! Tell him to take four days!
Just keep doing your best ... lifetime partners are hard to find! If he ever want to talk to me, let me know.
