Emergency dentist

I’m flying out tomorrow AM from the UK and will be in China for the next 2.5 months, wondering what anyone’s experiences are with dentists and what the rough cost might be?

I have a partially erupted wisdom tooth that’s been giving me trouble for the past couple of days, I think I’m going to have to get it removed either in China, or delay my trip if it’s not going to be worth the cost/risk etc. I’ve heard mixed reviews on dentists and I’m a student so don’t have loads of money to be spending on a tooth extraction.

I’ll be mostly between Beijing, Shanghai, Datong, so if any locals have any recommendations please lmk too!
