DD (20) is away at Uni.
Since mid Nov she has suffered with a mouth ulcer. Although it comes and goes , it doesn't ever go away. She put it down to stress, and didn't even mention it to our family dentist when she had a check up at Xmas
She called to say, it was causing her some pain and had gone to a local dentist near uni. He's made an emergency referral for her to get seen and said the dentist wants a biopsy taken. Other than that she couldn't tell me.
Obviously googling why this may be the case, has brought up all sorts of scary stuff..
Should I be worried or can there be 'lesser' reasons why he may have done this?
