Emergencies often occur outside of the clinic’s regular opening hours. Although we offer great availability, it could happen at night or a Sunday.

Here are the most common dental emergencies and advice on what to do to temporarily relieve pain until you can see a dentist.

These tips do not constitute a diagnosis. They can be very reassuring but in no way can they replace your dentist’s advice. Only your dentist will be able to make a correct diagnosis and suggest the proper treatment.


Feel free to contact us for additional information or any concern.


Some emergencies are of medical nature. When someone is a victim of a serious accident or a malaise, call 911 or go directly to the Hospital Emergency Department. Here are a few examples;

Possible jaw fracture

When you suspect a jaw fracture, immobilize the maxilla as much as possible.  You can apply ice to control pain and swelling.  Ideally, wrap the ice pack in a wet towel. Immediately bring the person to the Hospital Emergency.

Facial Lacerations

Immediately bring the person to the Hospital Emergency to obtain the best aesthetic result possible.

Dental trauma most often happens during accidents or a physical activity.

Broken Tooth

It is almost always possible to save a broken tooth. If the tooth is only slightly fractured and pain-free, you can make an appointment with your dentist in order to restore it. Aesthetic restorative materials are used to repair broken teeth and are almost invisible since they match the teeth’s natural colour. However, if your tooth is severely fractured and painful, it is likely that the dentin or pulp is exposed. A root canal and a...

Loose Tooth

A tooth can be displaced because of an accident (such as a fall) and it can become mobile and painful. This condition requires an emergency dentist visit to assess the possibility to solidify the tooth by attaching it to the other teeth. In the meantime, you can try to delicately put it back, if it is not painful.

Knocked-out Tooth

If the tooth has been completely expelled in an accident, your dentist may be able to re-implant it, but it has to be done soon! The sooner the tooth is re-implanted in its socket, the greater the chances to successfully embed the tooth back in the gum. Ideally, it has to be re-implanted within 30 minutes following the accident. Gently rinse your tooth and put it in a container of cold milk or water. Quickly go to...

Debris Stuck Between Teeth

You can first try to carefully remove it by using dental floss. Never use a pin or a sharp object as you may injure your gums or scratch the teeth’s surface. If it can’t be dislodged, see your dentist or hygienist.

Lost, Cracked or Chipped Filling

Temporarily protect the tooth by eating on the opposite side. Clean and rinse your mouth after eating and quickly see the dentist, depending on his availability for emergency visits. However, if you have a constant pain that wakes you up at night, you should see the dentist as soon as possible.

Temporary Cement Lost After a Root Canal

If the temporary cement is dislodged after an Endodontic treatment (root canal), clean and rinse the area and take an appointment with your dentist.

Cement or Complete Loss of a Crown or Bridge

It is important to temporarily protect the exposed part of the tooth (crown or bridge pillars)  to keep it in good condition. See your dentist as soon as possible.


After a surgery or a long dental procedure, it is important to follow your dentist’s recommendations. However, if you have fever, nausea, vomiting or bleeding, immediately contact your dentist to give you instructions.


Following surgery, the dentist places gauze (cotton) in your mouth. It is important to bite on the compress and keep good, constant pressure. You can change the compress after 30 minutes. If you are still bleeding, fold a compress in four and bite on it for another 20 minutes. Repeat until the bleeding stops. Resting will slow down blood circulation and promote coagulation. If you have no more gauze, you can use a slightly wet tea...

Pain following surgery

It is important to follow your dentist’s advice. Take the prescribed painkillers according to posology. Do not wait until pain is intense because it will be more difficult to control. If the pain persists or becomes unbearable, call your dentist’s clinic. If the clinic is closed, call Info Santé (811). The nurse will be able to assist you or give directions to the nearest hospital.


If the dentist has prescribed you antibiotics, it is important to respect the posology and take ALL THE PILLS to prevent any infection of the treated region, even if you don’t feel pain anymore. * Before any procedure, inform the dentist of your health problems and any medication prescribed by your doctor or specialist.


If the dentist used melting sutures, they will disappear on their own within the next 2 to 10 days. On the other hand, if it he has used silk sutures, they should be removed within the next week. This procedure is done without anesthesia and is painless. If silk sutures get loose before your appointment, contact your dentist and he will assess whether he needs to see you sooner.

Apply on the area for 15 minutes, then remove for 15 minutes.  Repeat a few times. Swelling can also occur...

Thumb Sucking

Thumb-sucking leads to irreversible deformations (a narrow palate, forward-inclined teeth and a bad occlusion). Thumb-sucking is a form of emotional comfort for the child. You must therefore help him and encourage him in this process. Fast tips: Write in a calendar...

Baby Teething

Teething can make the child irritable. He will cry, chew everything, will drool profusely and present a decreased appetite. Often, it is accompanied by pain, cheek redness and buttocks irritation. Although teething causes discomfort, your baby isn’t sick.

Some symptoms should not be automatically attributed to teething, such...
