Time to put your foot down Caroline

A referral via your GP will work just as well as a referral from a dentist. Pick the one that you feel is most likely to do what you ask and then lay it out for them.

You have been going through this for 6 months and so far the problem has not been fixed. Remind the doctor/dentist that despite adjusting the dental plate and taking antibiotics you still have a sore in your mouth. Let them know their solutions are clearly not working. You would like a referral to the ENT to get to the bottom of this once and for all. Now. Please. And no, being shunted back to the other healthcare professional is not an option - it didn't work the first time so why do they think it would work this time?

Why do people do the same thing over and over on the off chance the result will be different to the first time they did it. It's like looking for your lost car keys - you know you checked the dresser already, but you keep going back to it in case they have magically appeared. The exception would be any woman's handbag ...

For what it's worth, odds are you do NOT have cancer. Oral cancer is rare and even rarer for young women. However, you need to settle your mind so do whatever you need to to get that referral to a specialist.
