Dental Emergency Examples

We have included some of the more common dental emergencies and some of the things you can do to help yourself before visiting with our emergency dentists.


While mild toothaches generally don’t require an emergency dentist, a severe toothache usually comes with swelling, intense pain, fever and discharge. A severe toothache with such symptoms will most likely require a visit to our emergency dentists.

If you are experiencing a toothache, please try the following to see if it helps with the pain:

  • Clean around the sore tooth as best you can.
  • Use warm salt water and rinse your mouth to displace any food trapped between your teeth.
  • If your face is swelling, place a cold compress on the area.
  • Acetaminophen is recommended for temporary pain relief.

Do not use ‘aspirin’ under any circumstances!

Call our office for an appointment as soon as possible.

If the pain persists or worsens, call for our emergency dentist services and we will assist you right away.

Loose Or Lost Crowns:

If one of your your crowns becomes loose or falls out and you are in pain, please call us for an emergency visit or same-day appointment.

In the meantime, you can try the following to reduce your level of discomfort: Use dental cement, denture adhesive (or even toothpaste) to secure the crown back onto the tooth.

Important: Do not use any other kind of glues (including “Krazy Glue”) as they can actually damage the tooth and/or crown or make you sick.

Something Stuck In Your Teeth:

The first thing you can do when something is stuck in between your teeth and causing you discomfort is to use dental floss.

Gently and carefully, try to remove the object(s).

Do not poke between your teeth with any pointy or sharp objects as you might cut your gums or damage the tooth surface.

If the object remains stuck, please call us right away.

Lost Or Loose Dental Filling:

If one of your fillings is loose or has completely fallen out, cover the area with a piece of softened sugarless chewing gum.

This solution is only temporary, so be sure to call us as soon as possible to permanently fix it.

Infected (Abscessed) Tooth:

Untreated cavities can become infected.

If you know you’ve had at least one cavity for a while, it might now be infected.

If you are experiencing discomfort or severe pain from what you believe is an infected tooth, here are some of the telltale symptoms:

  • Severe pain
  • Foul taste in mouth
  • Bad breath
  • Swelling
  • Fever

Abscessed teeth that are left untreated can result in more serious health hazards, such as cellulitis and sepsis.

If you are experiencing any of the above, please call us for an immediate assessment and possible treatment options.

Broken Teeth:

If you have broken one of your teeth and are in pain, please call us immediately.

If you are not in immediate pain, try the following and then contact us for an appointment:

  • Rinse the area around the broken tooth (teeth) with warm water
  • Place a cold compress over the facial area of the injury.
  • Locate and keep broken tooth fragments.

All damage to teeth should be looked at by a dentist to ensure there are no related issues and that the original issue is dealt with professionally.

Knocked Out Tooth (Adults):

If one of your teeth has been completely knocked-out, please call us first and then do the following:

  • Find the tooth and be sure to hold it at the top (not by the end with the root).
  • Gently rinse it with warm water (do not use soap).
  • Put the tooth back in its socket and hold it there using a clean cloth or piece of gauze.
  • If the tooth cannot be put back into its socket, use a cup containing salt water to transport it.

Time is the most important thing here and you’ll need immediate treatment.
