Oh no, That is awful. Your poor hubby. I hope he gets better quickly and that there are no other injuries that pop up. I hope he is able to take it easy until he is fully healed. Friday seems really too soon, imho....
That is an odd reaction from the dentist, don't you think? Maybe he has seen this kind of thing once before and that is how it went down. He still should assess the situation and treat him. A lawsuit could take forever and who needs the hassle of all that when the other guys admits guilt and his insurance is already on board with all that.
I hope tomorrow is a better day.
