She mentioned her father’s sick teeth and about her life being screwed up and not moving anywhere... Can these two sentences lead her to having fear of aging or fear of wasting her precious time or life?
You also mentioned obsession. Can her dream be literally about her teeth just because she subconsciously thinks she can eventually have her teeth sick just like her father has?
She is still very young. I would probably tell her to relax and live her beautiful young age life.
