The effect of applying pepper in tooth pain is very limited. Pepper is considered to have certain anesthetic and pain-relieving effects, but for real tooth pain, which is very severe, the effect of applying pepper is not as ideal as imagined. Because most of the tooth pain is due to tooth decay has developed to the stage of pulpitis, the pain of pulpitis patients is very intense and difficult to be tolerated by patients, at this time, the application of pepper patients may feel the local pepper feeling, but will not cause much pain relief to the patients. So once the tooth pain occurs, you need to go to a professional dentist and apply a high-speed turbine drill to open up the pulp and release the inflammation in it, which is the best way to stop the pain.
