profession. It is known by various different names: dental orthopedics, dentofacial orthopedics, cranio-mandibular orthopedics, and jaw orthopedics.
Sinus infections often follow a cold and cause pain and pressure in your head and face. Sinusitis can be either acute (sudden) or chronic (long-term). With chronic sinusitis, the infection or inflammation does not completely go away for 12 weeks or more.
Chronic sinusitis may last 12 weeks or longer and usually requires 3 to 4 weeks of antibiotic treatment. Symptoms may persist or return despite adequate antibiotic treatment. A different antibiotic may be needed to treat the infection. Referral to an ear, nose, and throat (ENT) specialist (also called an otolaryngologist) may be needed if symptoms of sinusitis do not go away despite long-term antibiotic treatment.
