My son has just turned 6 and for the past few nights has been unable to sleep saying his cheek and ear hurt. Today I realised it might actually be his gum. I booked a dentist appointment for tomorrow, but will have to pay as the dentist I have been going to for 15 years suddenly doesn't take NHS patients any more. I just googled and apparently it's common for back molars to come through at the age of 6. Maybe that explains it. I don't really want to go and spend £50 tomorrow just to be told a new tooth is coming through! Has anyone's similarly aged child had similar pain around the same age?
