It is not uncommon for patients who have not had their teeth cleaned for a long period of time to have a large amount of tartar as well as plaque washed out of their teeth during the cleaning process. As plaque normally clings to the tooth surface, it causes isolation of the tooth surface from the oral cavity, and obvious symptoms of dentin sensitivity may occur after removal. In this case, you can apply desensitizing toothpaste by yourself and observe for a period of time. In most cases, the pain symptoms will be significantly relieved, and this is a good situation in itself. If the original tartar is not removed, it will grow deeper and form periodontitis, resulting in the loss of all teeth.
