Q. Hi Justin – Over the last 5 weeks, I have had antibiotics and used mouthwash constantly to clear up an abscess. On Monday after hygenist treatment, my mouth has developed a burning, stabbing sensation in the gums and also nerve pains in the face. Although now on medication for Oral Thrush, the dentist does not think this is the case. Her feeling is either allergic reaction to mouthwash, or Burning Mouth Syndrome. What do you think?
