My personal experience -
I met with an accident while riding a bike in India. I described my pain as 7/10 and I was told "it'll go away in a few days". That was it.
After immigrating to Canada, I had to get a tooth extraction done. The dentist prescribed acetaminophen with opiates "in case it hurts too much".
It did hurt, but nowhere close to what I had previously experienced. 🤷♂️
I mean, I was told to take ibuprofen for the pain too, not like they sent me home without any treatment lol. 😅
Waiting periods - I'm in Toronto, so I may be biased as the situation varies dramatically from one place to another. Yes, there's some waiting period compared to private hospitals in India.
If I have to see my family doctor, appointments are 1-2 weeks away. If you go to an ER for something that doesn't need an ER you'll end up waiting for over 12 hours while people who need immediate attention get priority (think heart attack, stroke, road accident etc).
There's no viable in-between, so non-emergency urgent requirements fall through the cracks and lead to a ton of frustration and annoying wait times. Eh: broken bones, high fever etc. where you're not actively doing so ER deprioritized you but you can't wait for 2 weeks to see your family doctor either.
I don't have experience with major issues like biopsies, mri etc and I've heard mixed opinions about timelines for those - a lot of the negative reviews were from the covid restrictions era though.
All that said, dentists are not a part of ohip. I paid using a combo of private insurance and cash. My dentist (55+ y/o - semi retired) works five hours a day, three days a week. He is not under any pressure. He prescribed opioids for pain because that's the norm.
