when I was in NSW (Sydney) we had 2 hospitals in my area that had the free dental. I got in the day after I called once, the following week the second time & a couple of days later the last time.

They have it here in QLD aswell, I had to wait about 4 weeks for a tooth reconstruction after a tooth broke (not painful which is why I had to wait) & DS has his appt next Wed, he waited about 8 weeks I think, but he hasnt got any pain, his is just a check up as he hasnt been to the dentist before & I want him to have regular check ups.

DD's school has the dental van but I called them as she was having pain from a hole in her tooth & they fit her in that week. She had 2 small fillings done.

Can you google & check if theres something similar in or around your area? Even if its 8 weeks waiting time you're still going to be doing nothing about it in those 8 weeks anyway because you cant afford it, might aswell take an appt with a long wait period IYKWIM?

I hope you can find something, I have a long history with a private dentist due to my very bad teeth & I have spents $1000's literally on my teeth & they're still crap!

Good luck!
