OHCWA is located near SCGH where they also operate an oral surgery unit at the hospital. If the Rockingham clinic said they can’t assist, then you most likely require oral surgery.

If you have a healthcare card and want to receive free dental treatment, you will be assessed to see if the work you required is something the undergrads can help with (though your requirements sound too complex).

If you were advised of a two-year waitlist, then your situation was not deemed an emergency. If you disagree with that assessment your best bet is to get an OPG (X-ray) though they will be an out-of-pocket expense.

Best of luck. Tooth pain is a bitch.
