My friend and I just had the exact same experience with different emergency dentists, a few weeks apart in different areas of the country.
Both had wisdom teeth out on the Weds, with stitches. Both got dry socket, with pain worsening. Both became aware of this late Friday night, necessitating a trip to emergency dentist on Saturday. Both were seen for about 2 minutes, and just given antibiotics - no treatment for the dry socket. The antibiotics in both cases failed, because in both cases the problem was food stuck in the wound which hadn't been cleaned out. Both had to go back multiple times after this to the dental hospital where we'd had the work done for actual treatment of dry socket and cleaning. Both were only given a syringe to help with the cleaning late in the day, when this would have been helpful from the moment of dry socket diagnosis.
AIBU to think that this may not be a coincidence and that emergency dentists are routinely handing out antibiotics unnecessarily, when they should be cleaning the wound and treating the dry socket? It seems crazy, in the context of constrained NHS resources, that they are leaving patients in pain and necessitating further appointments because they're not really treating the problem. What is going on?
