I'm a healthy non-smoking 31 year old male. I had a tongue ulcer on the side of my tongue for over a month, and it's affecting my eating and swallowing a bit. I went to a dentist who gave me an antibiotic mouth wash and told me to come back in another month. I cancelled my appointment because I was away travelling for work. I just got back and called to reschedule my appointment, but they say they're busy and I'll have to wait until Friday. My mouth hurts, and though I know I'm not in a high-risk category it's raised around the edges in a way that looks like photos I see online of oral cancer. It hasn't changed much in these past two months but it's making me anxious and it's very annoying.
Was a dentist even the right person to go to? I'm not sure if I'm supposed to go to a dentist or doctor for this kind of thing, and should I just make a doctor appointment instead since my dentist is busy?
