Since Zerodol-P (which contains aceclofenac and paracetamol) hasn't provided relief after three days, it is very important to visit a dentist as soon as possible. Persistent dental pain often points to an underlying issue, such as an infection or inflammation deep inside the tooth, which pain relievers alone cannot cure. In the meantime, try rinsing your mouth gently with warm salt water and avoid chewing on that side. Please do not take more than the recommended dose of your medication. A dentist will safely find the cause and help you get lasting relief.
