Does Flucloxacillin help in case of a dental abscess?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I have a dental abscess. Will Flucloxacillin help?

Hello,

Welcome to icliniq.com.

Firstly, I would like to know if you are sure it is a dental abscess or if it could be another tooth infection. I do not know if you have visited a dentist for this problem. Also, if available, forward me your X-ray or any other investigation reports.

If it is a dental abscess, you need to start with warm saline rinses at least five to six times a day for a week. Take half a teaspoon of salt in a glass of warm water and rinse thoroughly. External ice pack application will help you in case there is swelling. Do not sleep on the affected side.

Coming to your question, Flucloxacillin does help in case of a dental abscess, but it is always advisable to visit your dentist for a thorough check-up and get treated accordingly. Flucloxacillin 500 mg twice daily for at least three days should help.

Lastly, have you been allergic to any medicines in the past?

I hope this helps.

Thank you.
