tooth sensitivity for the last seven days. toothache in the morning. visited dentist last Tuesday. she said I had simply brushed so hard that her three fillings have given way causing this sensitivity. She asked me to continue with the the Colgate sensitive Pro toothpaste with an ultra soft toothbrush and go around the teelth gently. She showed me the demo on her laptop. How to brush the teeth ! Ok. Plus she also prescribed Thermokind mouthwash twice daily - after breakfast and at bedtime. This treatment is now on its 6th day and it seems to have made some difference; however, this morning it was aching so badly. When I had visited her on Tuesday she had fired some sprays with her gun at 6/7 places near the affected teeth, asking every time: does it pain ? Each time there was no pain, and hence she surmised that it is due to the sensitivity only and not a case of internal decay or something that would require digging into and doing something like route canal. My anxiety is to get over with the sensitivity. My chemist friend asked me to patiently wait for a fortnight !
