I've never had any treatment done to my teeth so am pretty clueless about dental treatments.
I have a back lower tooth that hurts when I eat something hard. There's no pain any other time or when I poke around with a finger. It's been there around 3 weeks. I'll try and get an appointment tomorrow but any idea whether it's likely to be a filling or root canal needed? Trying to pre empt the cost as its not NHS.
