Q. Dear Dr Justin Glaister! I am writing to you, as my husband is suffering from terrible toothache for the last 2 weeks. He took so many painkillers by now, and still no help. His tooth is aching almost every day, or every second day. We both know, he should go to a dentist urgently, but sadly we can’t afford those high prices. He is on the NHS waiting list, but it is ever so long. Is it true, if he goes to the hospital for emergency treatment, he gets it for free? We come from Hungary, and waiting to go home at the summer, and sort it out there. But this pain is getting unberable for both of us. Is any advise you could give him? Looking forward to hear from you. Thank you.
