What Counts as a Dental Emergency?

A dental emergency is any situation involving the teeth, gums, or mouth that requires immediate attention to stop pain, prevent infection, or avoid long-term damage. Some dental issues can wait a day or two, but others require same-day care.

You should seek emergency dental care if you experience:

  • Severe tooth pain: A toothache that is sharp, throbbing, or constant may indicate an infection, abscess, or deep decay. This should never be ignored, as the condition can worsen quickly.
  • A knocked-out tooth: If a permanent tooth is knocked out, immediate treatment gives you the best chance of saving it. Time is critical — ideally within one hour.
  • A cracked, chipped, or broken tooth: Breaks can expose the inner tooth layers and lead to infection. Even small cracks should be evaluated quickly.
  • Swelling in the gums or face: Swelling can signal an infection or abscess, which can be serious if not treated promptly.
  • A lost filling or crown: Exposed tooth surfaces can cause pain and sensitivity. A dentist can replace or restore the restoration before further damage occurs.
  • Bleeding that will not stop: Persistent bleeding after trauma or dental surgery requires immediate attention.
  • Injury to the mouth or jaw: Accidents that involve the lips, gums, cheeks, or jaw should be evaluated as soon as possible.

If you are ever unsure whether your situation is an emergency, the safest choice is to call the dental office. Our team at Brookside Family Dentistry can guide you through the next steps.

What To Do Before You Get to the Dentist

When a dental emergency happens, quick action can significantly improve the outcome. Here are some steps you can take for common emergency scenarios:

Knocked-Out Tooth

  • Hold the tooth by the crown, not the root
  • Rinse gently without scrubbing
  • Attempt to place it back in the socket
  • If not possible, store in milk or saliva
  • Seek immediate dental care

Cracked or Broken Tooth

  • Rinse with warm water
  • Use a cold compress to reduce swelling
  • Save any broken pieces if possible
  • Avoid biting or chewing on the affected side

Severe Toothache

  • Rinse with warm water
  • Use floss to check for lodged food
  • Avoid aspirin directly on the gum as it can cause burns
  • Call the dentist promptly

Lost Filling or Crown

  • Keep the restoration if you still have it
  • Temporary dental cement (sold in pharmacies) can offer short-term relief
  • Schedule a same-day appointment

Swelling or Abscess

  • Do not apply heat
  • Use cold compresses
  • Rinse with warm saltwater
  • Seek immediate care, as infections can spread

The sooner you contact an emergency dentist, the better the chances of saving the tooth and preventing complications.

Why You Should Not Wait to Treat a Dental Emergency

How Brookside Family Dentistry Handles Dental Emergencies

We know emergencies are stressful, and our goal is to make the process as smooth as possible. When you call us with an urgent concern, our team will:

  1. Assess your symptoms over the phone: We determine whether you need immediate care or if home measures can offer temporary relief.
  2. Offer same-day appointments whenever possible: Dental pain is never something you should have to endure.
  3. Provide comfortable, efficient treatment: Whether you need a root canal, filling, crown, or extraction, we focus on relieving pain and restoring your oral health.
  4. Guide you with clear aftercare instructions: Your recovery is just as important as the procedure itself.

We are committed to being the emergency dentist O’Fallon families can depend on.

Preventing Future Dental Emergencies

While accidents happen, many dental emergencies can be prevented by following good oral habits:

  • Brushing and flossing daily
  • Visiting the dentist every six months
  • Wearing a mouthguard during sports
  • Avoiding chewing ice, hard candy, or non-food objects
  • Getting recommended treatments before problems worsen

Routine care is one of the most effective ways to avoid unexpected dental pain.

I was terrified to go tot he dentist because I was embarrassed about my teeth, Ms. Randee made me feel so comfortable and at ease. Dr John was very nice and professional and I didn’t feel judged at all. A scary experience was definitely turned to a pleasant one - I will definitely be going back !

Pleasant experience per usual. I specifically enjoyed that the Dental Hygienist gave me the "whys" of what was happening and what I can do to prevent the aggressive scraping. I had many questions and she took the time to explain everything.

As someone with severe dental anxiety, the entire team at Brookside Family dentistry went out of their way to make sure I was comfortable and on my way to a speedy recovery in no time. At no point did I feel rushed, the dentist and his assistant were very accommodating, patient, and kind. Will definitely be returning in the future.

What a great place to go get your teeth done everyone there is very kind. Dr. John is awesome. He’s like the best dentist I’ve ever been to very gentle and does a great job. I’ve had four crowns and a filling plus a wisdom tooth taken out just a few days ago and he did an awesome job and I’m doing very well thanks to dr. John and the staff.

Had a crown come loose and my dentist for the last 15+ years retired and I needed to find a new one. To my surprise, Dr. John was able to see me the same day I called for an appointment. Everyone at his office in O'Fallon was so polite and professional. Dr. John I definitely is now my new dentist to take care of my teeth in the future. Thanks also to Crystal in the front office and Deja the hygienist for prompt and friendly attention in solving my issue with my crown. I highly recommend Dr. John if you are looking for a new dentist to take care of your teeth.
