Hi Stephany,
and welcome to the site. I don't think any of us could recommend a treatment plan but some here had have their jawbones rebuilt by taking a bone from their leg and have had dental implants as well.

With a recurrence, radiation is a must. Six weeks is pretty much the standard course.

Others on the site have had recurrences and have fought and won the battle so don't give up hope. I am sure that once they see your post they will be responding to you.

Discomfort is a given with any kind of treatment in the oral cavity but the effects can be effectively managed with pain meds. It isn't really the issue anyway - this is a fight for life.

You may wish to get a second opinion from a comprehensive cancer center if you are not already in one.

I will keep you and your mother in my prayers.
