My ear keeps popping and making crackling sounds non-stop, every day. the doctor told me i didn't have an ear infection or wax buildup. i was also having head and jaw pressure. almost felt my jaw locked once. could this possibly be a tmj?

The Eustachian tubes are a thin tube connecting your middle ear with the back of the throat. It allows mucus made by the walls of the middle ear to drain out & air from the throat to move in, equalizing the air pressure on the ear drum. The popping occurs when a partly collapsed tube lets air enter. It is not a disease & often increases in allergy season. It is not TMJ.

You may want to consider a WaterPik, floss threader, or interproximal brushes. discuss these and other alternatives with your Dentist and/or Hygienist. As ev very mouth is different, and every contact area between teeth is different, ask your care givers to create an individualized oral hygiene program for maximum effectiveness.
