Dental Extractions/Wisdom Teeth Removal: Instructions Following Oral Surgery

Please follow the guidelines below. Call Dr. McCallum if you notice any unusual symptoms.

If you have any questions or concerns, call our office at 519-828-3895. There is always a doctor on call when the office is closed.


  • Take all medications as prescribed. If you were given an antibiotic, please take it to completion (unless directed otherwise).
  • Medications on an empty stomach may cause nausea/vomiting. Take all medications with food and fluids.


  • Local anesthetic (dental freezing) will last anywhere from 2 to 6 hours and at times up to 12 hours.
  • Alternating an anti-inflammatory medication (eg. ibuprofen, naproxen) with a Tylenol-based medication (eg. Tylenol, Tylenol 3, Tramacet) is recommended (ie: start with ibuprofen → 3 hours later → Tylenol → 3 hours later → ibuprofen etc.).
  • Pain will peak at 48 hours and improve slowly over the next few days.


  • Bite down with firm, constant pressure and change the gauze every 30 minutes as bleeding persists throughout the day. Minor bleeding can continue for a few days following surgery. Gauze packs are not needed for this level of bleeding. If heavier bleeding does occur, bite down firmly on a dry, black teabag (wrapped in a piece of gauze). Apply constant bite pressure for 45-60 minutes before removing.
  • Remove gauze when going to bed at night or if napping. Sleep with your head slightly elevated for 48 hours after surgery.
  • Avoid aggressive spitting and hot fluids/foods for the next 48 hours.

Facial Swelling, Bruising and Stiffness

  • Swelling is to be expected following surgery. The degree of swelling can vary widely among patients.
  • As a rule, swelling peaks at 48 hours and persists for 1-2 weeks.
  • Use ice 20 minutes ON and 20 minutes OFF for the first 48 hours after surgery. Switch to moist heat after 3-4 days for comfort.
  • Mild to moderate bruising may occur (purple/blue in colour during the first 1-3 days and yellow/green in colour from days 3-7). It may travel down the neck and towards the chest area as time progresses.
  • Jaw stiffness and limited mouth opening can occur and may require stretching exercises for 1-2 weeks.
  • If new swelling occurs after the first 3 to 4 days, please call our office for guidance.

Oral Hygiene and Syringe Use

  • Start gently brushing the day of surgery.
  • Rinse several times daily with salt water (1 tsp salt in glass of water) after eating and at bedtime.
  • Use the prescribed mouth rinse (Chlorhexidine) 3 times per day. Rinse for 1 minute then gently spit.
  • A Monoject syringe may have been provided in your home care bag. Begin using the syringe 4-7 days after surgery by inserting the tip directly into the lower sockets. Gently flush (pulsatile) the socket after meals and at bedtime (4 times/day) using water, salt water or the prescribed mouth rinse.
  • Do NOT smoke for 2 weeks after your surgery. This includes cigarettes, e-cigarettes and marijuana.


  • Most stitches are dissolvable and will release in 4-10 days. An appointment will be made for you to remove any non-dissolving suture.
  • If sutures become loose, you can remove them with tweezers or carefully trim any long ends.

Diet and Nutrition

  • Cool, soft foods are ideal for the first 2 days following surgery. Continue with softer foods for 1 week as directed by your doctor. Avoid crunchy foods for at least 3-4 weeks and straws for 1 week.
  • Drink plenty of fluids (an average-sized adult will need about 2-3 litres/day unless medical history dictates differently).
  • Avoid alcohol for 1 week after surgery.

Numbness or Tingling of the Lip or Tongue

  • Due to the positioning of some impacted teeth, numbness to the lip, chin, gums and tongue and/or loss of taste may occur. It may take days, weeks or even a year for the sensation to improve. In some situations, however, normal sensation may never fully return.

Denture and Retainer Use

  • If new dentures have been made, they may or may not fit properly following surgery. Keep them inserted if you are not bleeding. If bleeding persists, take the dentures out and bite with firm pressure on the gauze provided. Post-operative swelling may temporarily affect a proper fit as well.
  • Please book an appointment with your dentist or denturist within 1-3 days to start any adjustments.
  • Retainers can be left out for 2-3 days after surgery.

Signs of Infection

  • Signs of infection may include: new swelling, elevated temperature and feeling unwell four or more days after surgery. Please call the office to describe your concerns.
  • Good oral hygiene can reduce the risk of infection.
