What to Expect from General Anesthesia and Deep Sedation -- dental office Mississauga

In specific dental procedures, the dentist will need for the patient to be under anesthesia – local or general, or intravenous sedation. During the preliminary consultation and discussion with the patient, the dentist should explain the most frequent side effects of any anesthetic which include:

  • Nausea
  • Vomiting
  • Sore throat
  • Muscle soreness
  • Inflammation with tenderness or bruising around the intravenous site
  • Postoperative pain, depending on the procedure performed


The family dentist Mississauga patients see should also advise the patient on anesthesia-related complications which rarely happens after a dental procedure. Patients should be clearly aware about these rare complications that could arise from the procedure which may require hospitalization or may result in brain damage or death.

Some of the anesthesia-related complications include pain, hematoma, numbness, infection, swelling, bleeding, skin discoloration, allergic reaction, tooth damage, and fluctuations in heart rhythm and/or blood pressure.

In order to minimize the risks of general anesthesia or deep sedation and to prevent any foreseeable problems, patients are advised to adhere to some sedation dentistry general rules which have significant impact on the effects of anesthesia, such as:

  • Avoiding alcohol, prescription medication which is not known to the dentist or anesthetist as these may aggravate drowsiness and lack of coordination when under anesthesia.
  • Avoiding the operation of any vehicle while still experiencing the effects of anesthesia which could take at least 24 hours after the procedure.
  • Avoiding making any critical decisions until completely recovered from the effects of anesthesia.
  • Designating a responsible adult who will accompany the patient to his/her residence following a major dental procedure. Such adult should provide care for the patient as well for at least 24 hours after the procedure to make sure that the needs of the patients are attended to.
  • Informing the anesthetist or the dentist of a suspected or confirmed pregnancy prior to the procedure with the understanding that all anesthetics and other medicines can cause harm to an unborn child and could cause birth defects or result in spontaneous abortion. The same applies if the patient is a breastfeeding mother. It follows that the procedure will be accordingly postponed as a result of these information.


While under anesthesia, the patient will be given fresh oxygen and if necessary some sleep medicine administered through the mask to breathe. Monitor stickers will be placed on the patient’s chest and a clip is placed on the finger. A blood pressure cuff will be placed around the arm for constant monitoring. Adult patients are provided with small intravenous catheter placed in the back of the hand to facilitate giving fluids or medications.

Under general anesthesia, the patient will be completely asleep for the entire duration of the dental procedure. Patients will normally awake about 15 to 30 minutes after the procedure has been completed. Upon rousing from anesthetic sleep, patients will feel dizzy and disoriented. The family dentist Mississauga reputable dental clinic representative will only allow the patient to go home if there is a responsible adult designated to accompany and provide care for the patient for at least 24 hours after the procedure.
