<s>[INST] hi I've a dental infection that I've been dealing with.  Anyway, I believe it's caused me some anxiety.  fOR A WEEK I've had a fear of eating.  I feel I can't swallow.  I have this fuzzy feeling in throat - dry throat.  I find myself constantly swallowing.  is there a medical condition or is this mental [/INST] Hi,As per your complain throat dryness when having a dental infection can be due to mere anxiety while in case if you are constantly breathing through mouth then it can also give you a dry throat. So in case if you have tooth infection then you should just relax as there is nothing to get so anxious and suffer from side effects and it will be better to consult a Dentist and get evaluated and an x ray of tooth can be done.You can be advised a course of antibiotics and painkillers followed by treating the tooth with root canal treatment or extraction of tooth depending on the condition of the tooth.Hope this helps. Let me know if I can assist you further.Regards,Dr. Honey Arora </s>
