The doctors have ample experience dealing with dental trauma and for many years Dr. Hawryluk Sr. has dealt with many dental sports emergencies as he was the official dentist for the Toronto Maple Leafs. Dr. Hawryluk Jr. has also treated many sports related dental emergencies and was the dentist for the Toronto Marlies Hockey Team. Dr. Taheri is a Board Certified Prosthodontic Specialist and has ample experience reconstructing the dentition after a dental emergency such as dental trauma.


A dental emergency can take many forms. It can be related to swelling or pain in your mouth. Sometimes there can be an ‘esthetic dental emergency’ such as when a front tooth fractures before you have an important event to attend. Similar to medical emergencies, dental emergencies must be diagnosed and treated by the appropriate clinician in a timely manner before any condition worsens. When you arrive at St. Lawrence Dentistry we will ask you a brief history of your dental emergency. It is important that you provide your dentist with the correct information and be as accurate as possible. The dentist may ask when the pain started, if it comes and goes, whether or not you have taken medication recently, and what symptoms you are having. This will help Dr. Hawryluk make a diagnosis and treat your dental issue.

Examples of Dental Emergencies are severe toothaches, fractured teeth, knocked-out teeth, lodged foreign bodies in teeth, and severe gum injuries


A toothache can be related to dental decay reaching the dental nerve of the tooth. When this happens the tooth can start to hurt and sometimes the pain can be overwhelming. If this is the case and you live in Mississauga it is best to contact St. Lawrence Dentistry as soon as possible. A toothache can also be related to a dental abscess. This is when there is a collection of bacteria in the tooth and at the end of the tooth root. Sometimes the bacteria can rapidly expand and result in both a dental and medical emergency. Dr. Hawryluk will carefully assess the cause of your toothache and remedy the tooth pain you are having. Sometimes an emergency root canal is needed. If a tooth is very broken down sometimes a tooth extraction is needed. Antibiotics to help control a possible bacterial load may (or may not) be needed as well. Ideally pain medication should not be taken immediately if possible as they can mask the symptoms the dentist will have to diagnose. Sometimes the dental pain can be temporary reduced by rinsing your mouth with warm water. This is good for removing the dirt or any food particles around the affected tooth. If you’re experiencing inflammation you can apply a cold compress to the outside of the mouth or the cheek near the area which is inflamed, never try to apply a painkiller or aspirin directly over the affected area because the chemicals may burn the tissue and make matters worse.

Case A Before: Fractured decayed teeth needing emergency dental treatment

Case A After: Decay removed, teeth sealed, and discomfort relieved

One less common dental emergency is an ‘avulsed tooth’. This is when a tooth is completely knocked out of the tooth socket intact. Unlike chipped or broken teeth a knocked out tooth can be put back in its socket shortly after it has been forced out of its natural position. Only a dentist should re-implant your tooth and it must be done ideally within an hour. If you knock out a tooth it is advisable to put it on a tissue growth substance such as milk, water with a small amount of salt, or a save-a-tooth container. If you are rinsing your mouth after your tooth has been avulsed be sure you put a cloth over the drain so your tooth does not go down it. Successful tooth re-implantation can be performed on patients who are able to get in touch with their dentists within one hour after the tooth has been knocked out. If the knocked out peace still has some tissue attached to it don’t try to remove it, leave it as it is and take it with you to the dentist. In order to avoid inflammation you should apply a cold compress to the outside of the mouth or cheek in order to prevent inflammation.


A lodged foreign body is a common dental emergency. The most common occurrence of this is when a popcorn seed gets trapped below your gum line. Most of the time this happens in someone who has bone loss around their back teeth and there is ample space below the gum for the object to sit. It is amazing how a small particle can cause major inflammation in your gums. If gentle flossing cannot rid your gum of the object it is best to stop flossing and have your dentist examine the area. Sometimes flossing can push the object deeper into the gum. The dentist may need to place local anesthetic and clean the area with ultrasonic instruments to dislodge the object.


Fractured teeth from an accident can be classified as both a dental and esthetic emergency. Sometimes the dentist can fix a fracture by dental bonding. This is a where the missing piece is simply replaced with composite resin. This is the best case scenario for fractured teeth because this treatment is very conservative and a lot of times does not involve drilling on the tooth. However, sometimes the facture can be so deep that the tooth nerve is exposed. In these cases the dentist may have to do an additional procedure such as a direct pulp cap or root canal treatment. Finally, if a fracture is large a dental crown is sometimes needed to protect the tooth. The dental crown is the strongest and most definitive type of dental restoration.

Most dental emergencies should be handled by a dentist. However, if you are unable to reach a dentist you may need to seek medical attention at your nearest hospital. Situations where you may need to go the emergency room or the hospital are severe pain, swelling which is increasing rapidly, trouble breathing or swallowing, and/or feel febrile. The nearest hospital to St. Lawrence Dentistry is Trillium Hospital on Queensway. The medical team at the hospital will consult with the dentists/oral surgeons on staff if needed.

In addition to being open weekdays, we are open on Saturdays for your convenience.
