How can I treat my back tooth cavity and pain?

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

Patient's Query

Hi doctor,

My back tooth has developed a deep cavity within a few months. Now I have a pain in that tooth, which got worse this morning. My cheek and throat are sore, and they are swollen. It became a deep cavity when my filling fell out.

Please help.

Thank you.

Hi,

Welcome to icliniq.com.

I can understand your concern. As per your history and symptoms, it seems to be acute apical periodontitis, which means that you have an infection in that tooth and the associated area. For immediate management and recovery, take the following medications.

Take one tablet of Augmentin 625 mg (Amoxycillin with Clavulanic acid) twice daily for five days and tablet Lyser D (Diclofenac with Serratiopeptidase) twice daily for three days. In case, if you are taking any medication for some other reason, and if you are allergic to these drugs too, avoid this medication.

I hope this helps.

Thank you.
