Gabitril Healthy Teeth, Baby Teeth, Cause Tooth Decay, Noticed That Some, Risperdal

Don't know if completely related but daughter (9) was put on gabitril 10mos ago for PTSD... she seemed to be fine on medication, sleeping through the night finally. But she is homeschooled and I noticed that some days she would forget everything she had been taught the day before. Last week of May this yr she was playing at a birthday party and got overheated, she started having tremors, trouble paying attention, and very clumsy...Thought was related to Risperdal that she is also taking so we got her cooled off as fast as we could. Tremors lasted two days. Doctor said was unaware what would cause symptoms I was describing. A week later we took her for yearly dental x-ray and 6mo cleaning. Dentist found two teeth with internal root resourption (not common in 9yr olds) lucky for us they are baby teeth, but are not to come out for two years, they will have to be pulled and spacers put in to make room for perm teeth. Started asking questions about medication and dental problems, found that med can cause tooth decay and other problems. Don't know if that is what caused her teeth problems but x-ray last yr showed two healthy teeth. Has any one else had dental problems taking this one? Think we are going to give up a good night sleep to keep the teeth.
