hello, you can do warm salt water rinses as a home remedy, but this will give you only temporary relief from pain. you need to visit a dentist and get it checked. get an x-ray done. the smell could be because of infection to the roots of the tooth. you need to get that tooth treated and then get a crown placed over it. Book an appointment with Dr. Puja Bansal, Prudent International Health Clinic, kalyani nagar, pune.
