Thanks for posting your query,
There are many factors that may lead to sensitive teeth, including.
Inflamed and sore gum tissue may cause sensitivity due to the loss of supporting ligaments, which exposes the root surface that leads directly to the nerve
of the tooth.
Chipped or broken teeth may fill with bacteria from plaque
and enter the pulp causing Inflammation.
Sensitivity can occur following teeth cleaning
, root planing, crown placement, and tooth restoration. Sensitivity caused by dental procedures is temporary, usually disappearing in four to six weeks.
Get professional tooth cleaning, oral hygiene
instructions, and fluoride
treatments every six months (or sooner depending on your condition).
I hope this information has been both informative and helpful
