Preoperative And Postoperativecare Sheets

Our priority: your well-being

Remember that you can reach Dr. St-Onge any time following a procedure.

Preoperative and postoperative instructions for implant surgeries

General preoperative instructions
  • If you have dentures, avoid wearing them for a while, at night and when your activities permit.
  • For 10 days, do not take any aspirin.
  • Ask someone you trust to accompany you the day of the surgery.

Postoperative instructions

  • For 30 minutes afterward, hold the compresses with light pressure from the jaws. Do not spit, rinse your mouth, gargle, or drink with a straw.
  • For 3 days, it is normal to have pinkish saliva (stained by a little blood). In case of prolonged bleeding, apply another compress (or a damp teabag) and hold it in place with light pressure from the jaws for about 2 hours.
  • For 2 hours, avoid eating and drinking.
  • Do not put your fingers or tongue on the surgical site (the location of the operation).
  • When you are lying down, make sure that your head is raised with a cushion or pillow.
  • Sleep with an extra pillow.
  • Apply ice in 10-minute periods, about 3 times an hour. Repeat as often as possible. If pain or discomfort persists after 2 days, replace the ice with a source of moist heat. For example, apply a warm washcloth.
  • For about 4 days, do not eat solid foods. Switch to a liquid, room-temperature diet.
  • For 7 days, speak as little as possible and avoid overextending yourself and all physical activity.
  • For 7 days, do not take any aspirin.
  • Take the medications prescribed by your dentist.
  • Apply lip balm if you have chapped lips.
  • After meals, gently brush the areas that have not been affected by the procedure (be careful around the surgical site and sutures).


For 2 weeks, smoking is strictly forbidden since it slows down the general healing process. In particular, smoking slows down the scarring of tissue and can even affect the results of the procedure.


For 2 to 4 weeks after the procedure, use the prescribed antiseptic mouthwash twice a day: in the morning after breakfast and at night after dinner. If you run out, concoct a homemade mouthwash by mixing 1/2 tsp. of salt in 8 oz. of water.


Pendant les 2-3 jours suivant l’intervention, l’enflure est normale.

Discolouration of the skin

For 2 weeks, you may notice some skin discolouration. It will return to its normal appearance shortly. Do not worry.


Your dentist will remove resorbable sutures (dissolving sutures) during your monitoring visit planned 2 weeks after the procedure.


For 2 weeks, continue favouring soft, nutritious foods (e.g. cooked vegetables, cooked fish, pasta, ground meat, etc.), and do not wear your dentures when eating. For 4 days, do not drink with a straw.

Denture base

Two weeks after the procedure, your dentist will apply a cushion (soft lining) inside the denture.

Mouth and nose (for sinus bone grafts only)

For 7 days, do not blow your nose. If you need to sneeze, do it with your mouth open to avoid undue pressure on the sinuses. If needed, take a decongestant and a saline water product (like Salinex). During the days following the procedure, you may notice small granules in the mouth. Do not worry about this. If, however, you feel granules in the nose, call your dentist.

For the slightest problem, call 450-444-5900 immediately (during business hours) or 514-217-3707 (when the clinic is closed).



Do a fluoride treatment to minimize the risk of tooth sensitivity. You can use a toothpaste that relieves tooth sensitivity (like Sensodyne®) or we can even prescribe you PreviDent® or Fluoridex™ toothpastes, which have a higher fluoride content.

There are two methods for applying toothpaste with a high fluoride content:

  1. Put some toothpaste into your trays, then place them in your mouth for about 5 minutes. Spit out, but do not rinse until 30 minutes later. Do not forget to clean your trays well before putting them away.
  2. Put some toothpaste on your toothbrush. Brush, but do not rinse, drink, or eat until 30 minutes later.


Apply the whitening gel, but, before you do, remember that it is essential to give your teeth a good brush and use dental floss first. This way, the gel will spread over the teeth evenly and you will get an optimal result.

Using the syringes, put a very small amount of whitening gel into the trays (the equivalent of a grain of rice).

Place the trays on the teeth of both jaws without exerting any pressure, or else the gel will spill over. If, despite these precautions, you get gel on your gums, wipe the excess off immediately without pressing on the tray.

Avoid eating tomato sauce, soy sauce, and any food or spice that stains teeth (curry, turmeric, etc.).

Avoid drinking red wine, coffee, tea, and brown carbonated drinks (like Pepsi and Coke).

Smoking is strictly forbidden during the treatment (especially in the hours before and after the application).

Avoid brushing your teeth immediately after the treatment to prevent abrasion.


Before putting gel into them, make sure that your trays are clean. If not, run warm water over them and dry well.

Clean them again before putting them away.

Keep your trays in their case in a safe place, out of reach of certain pets, who seem to love them!

Under optimal conditions, your trays can be kept for 5 years. If you take good care of them, you can do whitening touch-ups once or twice a year to maintain the whiteness of your teeth.
