Hello doctor,

I have a tooth filling that has come out, and woke with a white lump beneath it on gum, swollen lower face too on the other side of the site of lump. I had a dull, drumming pain during the night before. I rinsed with warm salt water this morning. Wondering if Flucloxacillin 500 mg which I was prescribed for a bad reaction to summer insect bites and too worried to take, would they help gum infection or abscess? Are four tablets a day all right? I have a dental phobia and will need to wait to be treated at my local hospital.



Welcome to

Your tooth is probably infected which has caused the white lump on your gums. The decay has gone inside the pulp, almost touching your nerve and there is infection beneath the root of your teeth which has caused this swelling. You will have to confirm the status of your teeth by taking an X-ray, to check how much the infection is affecting your tooth. I will not suggest you having Flucloxacillin 500 mg because it is not effective for dental infections.

To suggest an antibiotic, I need to know the proper medical history of yours. At present, take an antibiotic and pain killer so the swelling subsides and meet a dentist as soon as possible for further treatment. Can I know if you have any allergies for any medicine, or any systemic diseases present? If so, I can prescribe the medicine for you.
