I have been to the dentist about 4 weeks ago and he had to replace a loose filling & gave me anitbiotics and ever since then I have had a niggling pain (occasionally) on the right side of my mouth, then last Monday, Tues, Wed I had a nawing pain which came on at tea time so took painkillers and it disappeared. On two consecutive nights at the weekend I woke during the night with a nawing pain on the right hand side of my face, lips , gums, tongue and jaw (took some painkillers but took ages to settle so that I could sleep). Made appt at dentist yesterday and he took an x-ray but could not see any problems so gave me more antibiotics to take and I have another appt with him on Friday afternoon. The right hand side of my face flared up again tonight with the same symptoms as the weekend!!
