[farsyed0214]

Hello . My dad has been diagnosed with head and neck cancer. Its been very hard journey. He smoked in past and never went to dentist. I feel like I'm doing better with dentist visits and cleaning. I had head x rays in dentist office in july I noticed a tiny very light white spot on side of tongue. I went for perio cleaning in Nov. I have anxiety especially seeing my dad suffer right now. Its to the left of the star in the picture. Can anyone look at it?I appreciate it.
