Hello, This is absolutely not normal and indicates an active infection that requires treatment. Have you been prescribed an antibiotic and taking it at prescribed intervals? Contact your dentist or oral surgeon and report your condition. You most likely have a delayed healing involving the extraction site, commonly called a dry socket. Your dentist will curette the area and place medication. Drainage may need to be established. Follow all instructions and prescription medications to assist healing. Complications wilth healing abilities can relate to an early disruption of the fragile blood clot, irritants such as smoking or rinsing too early and prior severe infections. Seek attention to prevent this condition from worsening. Thank you for your inquiry.
