"Waiting in pain"

I have now been waiting double the waiting time just for a letter for my appointment. I was told 12 weeks and this is now the 24th week with no word of an appointment. I have phoned twice as I am in a lot of pain (waiting to get 2 of my wisdom teeth removed) and nobody can help me. The only response I get is ‘we don’t know how long the waiting list is but we’re full for the next 2 months at least. I’m now having to pay for treatment at my own dental surgery due to problems with these wisdom teeth. I don’t feel like I should be paying for this considering the teeth should be really be out by now. I have no idea when I will be getting these removed but I’ve never wanted to pull my own teeth out more than I do now because the pain is too much! !
