So I went to my lovely nhs dentist the other day, to be told I need numerous fillings, root canal and a crown. He has agreed to do all the work for me under the nhs price band 3 which I am incredibly grateful for as this would be near impossible usually. However he cannot see me till 5th june for root canal treatment and this morning I woke up in absolute agony, my mouth and glands are extremely sore. I would rather not lose the tooth and wait for root canal but any advice on what I can do in the meantime? Can my GP provide me with painkillers?
