For deep cleaning procedures, anesthetic is used, the anesthetic will generally last 2-4 hours depending on where the work was completed, so be careful eating because you may bite your lip or your tongue. The anesthetic injection site will be sore for up to two weeks, especially the lower jaw if the deep cleaning was on the lower arch. Generally, soreness and cold sensitivity will be felt for a few days after the deep cleaning. Please feel free to take Ibuprofen or Acetaminophen as directed for the discomfort. If the soreness and/or the cold sensitivity lingers for longer than two weeks, please give our office a call for an appointment.
