Someone from another forum mentioned that his/her dad also has epilepsy and has the same problems. I'm hoping its just the meds, but that persons dad is 50 and I'm only 20. I'm afriad mine might have gotten pretty bad really fast, considering my age and the time I've taken my meds vs. that persons dad.
I would suggest finding a good dental home where you can go to for questions like this. This is something a dentist would need to see clinically and look at your entire history to come up with the best solution for you. You sound like you are on the right path, and you have great questions to ask, be sure to find someone who will take the time to personally answer these for you.
Seeing a periodontist to take care of your gum is advised.
