You've found a wonderful place!
My heart goes out to you! As I read your post, I realized there are several forums here that could bring you much support.....and when I looked at the main menu, the forums that came to mind all happen to be listed right in a row!

If you click on the big "NeuroTalk" Logo at the top of the page, it'll show you the menu list of support areas......Like Redtail said, the Dentistry forum is fantastic.....full of knowledge!

Also, I'm thinking the "Medications" forum may be a good place to inquire about the issues you describe ....
ALSO, the "Coping with Grief and Loss" forum is listed right there as well! I'm so sorry about your mother....
No matter how many years go by after losing a loved one.....there's always that empty spot....

One thing I've found for sure here at NT, there is HOPE around every corner!
Introduce yourself anywhere you feel comfortable and you're sure to get good information (I'm having dental issues right now as well! .... NOT fun!) But the support here is priceless...

Truly Caring
