It is common to experience discomfort after a tooth extraction, but severe pain that doesn't respond to over-the-counter medicine warrants a call to your dentist. You may be experiencing a common, highly treatable condition called dry socket, where the protective clot dislodges. For stronger relief, alternating generic ibuprofen with paracetamol can sometimes be highly effective, provided you have no contraindications. Please avoid using straws, spitting, or smoking, as these can worsen the pain. I strongly recommend contacting your dentist or oral surgeon promptly. They can examine the site, apply a soothing dressing, or prescribe targeted prescription-strength medication to safely manage your pain.
