Types of Dental Emergencies


A toothache, as its name suggests, refers to a sharp or dull pain around the tooth. They are commonly caused by tooth decay, an abscessed tooth, infected gums, tooth fracture, or a damaged filling. Treatment will vary depending on the cause of the discomfort. But possible options include a filling, root canal or tooth extraction. See your dentist as soon as possible. Rinse your mouth out thoroughly with warm water, and if you can, use dental floss to gently remove any lodged food. If you experience swelling, put a cold compress on the outside of your cheek or mouth in the affected area.

The root cause of a toothache helps determine the appropriate treatment. In general, emergency dental care is focused on pain alleviation so follow-up appointments may be necessary depending on the situation.

Chipped or Cracked Tooth

You can experience a small, medium or large chip in your tooth due to excessive teeth grinding, trauma, a cavity or if you bite down on something too hard. Should this happen, see your dentist as soon as possible. If a piece of the tooth has come off, save it if you can. If there is any bleeding, apply a piece of gauze or a soft, clean cloth to the area until the bleeding stops (usually about 10 minutes). Apply a cold compress to the outside of the mouth, cheek, or lip in the affected area to keep any swelling down and to relieve pain.

Lost Filling or Crown

See your dentist as soon as possible. If you have lost a filling, you can temporarily place a piece of sugar-free chewing gum, or some over-the-counter dental cement into the cavity.

If a crown falls off, bring the crown with you if possible. If you can’t get to the dentist immediately, use a cotton swab to apply a small amount of clove oil to the sensitive area (clove oil can be purchased at your local drug store or in the spice aisle of your grocery store).

Particles Stuck Between Teeth or Under Gums

Floss gently to remove food particles after every meal to avoid tooth decay, cavities, and infection. If something is stuck in-between your teeth, try using dental floss to remove it. You can make knots in your floss to further help dislodge the object. If you cannot get it out, see your dentist as soon as possible. Do not use sharp objects to attempt to get it out yourself, they can cut your gums and damage the surface of your teeth.

Knocked-Out or Loosened Tooth

This type of dental emergency commonly occurs due to a fall, sports injury or other trauma. When it comes to chipped or knocked-out teeth, it is best to try and save the tooth if possible. Knocked-out teeth that are placed back in their socket within an hour have a high likelihood of being saved.

Knocked out tooth: See your dentist as soon as possible. Retrieve the tooth and try to place it back into the socket. If the tooth touched a contaminated surface, rinse it off very gently but DO NOT scrub as that may remove tissues necessary for reattachment. Hold it by the crown, and gently place it back into the socket. Bite down gently to hold it in place.

If you cannot place the tooth back into the socket, do not discard it. Put it in a small container of milk (or cup of water that contains a pinch of table salt). Whether or not you can replace the tooth in the socket, it’s important to get to our office as soon as possible.

Loosened or out-of-position tooth: See your dentist right away. If there is any bleeding, apply a piece of gauze or a soft, clean cloth to the area until the bleeding stops (usually about 10 minutes). To relieve any pain, apply a cold compress to the outside of the mouth or cheek on the affected area.

When Dental Emergencies Happen

Patients often mention that they are unsure as to whether a dental problem is an emergency. Our general rule of thumb is, if it hurts, it requires Emergency Dentistry. Quick treatment improves the odds of saving injured or damaged teeth.

We care about our patients and want to make sure that we are available to help you should one arise unexpectedly. We reserve time in our daily schedule specifically for dental emergencies and will accommodate both existing and new patients who are unable to see their regular dentist in a timely manner. We will offer our assistance over the phone to advise you on how to remain as comfortable as possible until you are able to be seen at our Mississauga office.  Our team is well trained and equipped to handle any situation and we offer effective and affordable treatment options.
