Any Cheap Dentists?

Got an xray and cleaning a couple months ago and paid so much $$ because I ran out of my dental coverage. During that session they also said that had I needed a root canal it would’ve been upwards of $1k… so i’ve honestly been ignoring all my teeth problems after that.

My bottom molar now has become so painful and turned grey. From my understanding, I think that i’ll probably need an extraction and replacement but definitely cannot afford something within that price range.

Are there any affordable dental clinics in hamilton that are good?
