Sorry your husband is having such a rough time with his teeth. I've been through similar problems. It's just the last straw to lose key teeth. It's not something we signed up for, is it? However, prosthodontists can do wonderful things.

One of my sons got married a week or so after the surgery and a couple of weeks before RT. I didn't want to go to the wedding minus front teeth so the hospital, feeling sorry for me, arranged for me to have a temporary plastic denture made to fill in for my front teeth and some side ones. My worries were cosmetic first and eating second.

This is a very difficult time in the process. Once the cancer is dealt with, your husband will be able to get his dental problems sorted. Eating solid foods is well nigh impossible during radiation anyway. I ended up living on Fortisip (like Ensure) with tinned peaches and chocolate icecream all blended together.

The teeth are kind of symbolic of the normal life we lose (for a while at least) in this process but there are solutions:)

Wishing you well:)
