Talk to Dentist on Teeth Issue

Hello, I am currently in Canada and I have been experiencing very severe pain in the lower-left back tooth for the past 6 days. The pain is getting worse and I am having difficulty managing it.

I was previously advised that this tooth may need to be extracted, but I did not have it removed at that time. I now need urgent/emergency dental care.

Could you please advise me if there is any emergency treatment or medication that can provide immediate pain relief until I can be seen? Also, could you please let me know the estimated cost of the examination and extraction if the tooth needs to be removed?

I currently do not have dental insurance, so I would appreciate it if you could let me know the most affordable option available.

Thank you.
