Last Wednesday I had two teeth extracted. My dentist said she thought she saw a faint shadow on my x rays from last visit(I'd had a check up the previous week). She said it could just be plaque build up, and she'd be able to get a better look after my hygiene visit in a couple of weeks. She'd told me that the top of the tooth looked ok, and she couldn't see anything in my mouth. She told me the oral cancer screen was nice and healthy at the check up, but I'm still really worried it's cancer.
