Emergency act on tooth ache

Hi all, I have a broken tooth one of which is abscessed, some more of it broke off eating something recently and it’s now getting precarious, to say the least.

I have a medical exemption certificate but am a bit confused about this, On searching on the internet, the dentists that accept non-fee paying adults seem few and far.

I am looking for an emergency dentist nearby Toronto. Can anyone with the previous experience help me out? I would like to hear from you. Please do share your suggestions with me.
