My mother is having a similar issue. I too think your "bumps" might be "Tori." I found a great website that was extremely informative. It is www.doctorspiller.com look under
"sores, lumps & bumps." You might not have found info under
Tori because the med name is: Torus Mandibularis. Hope this helps...until I found this website, I was a bit freaked out when my mother asked me to look into her mouth!
