Is it a dental emergency?

A dental problem is urgent when it causes severe pain, bleeding, swelling or damage that gets worse if you wait. Common examples are a knocked-out adult tooth, a tooth pushed out of place, a cracked tooth with sharp pain, a swollen gum or face from an abscess, and bleeding after an extraction that does not slow down with pressure. A lost filling, a chipped tooth without pain or a loose crown is usually not an emergency but should be seen within a few days. Our dental emergency checker walks you through common problems and how fast to act.

Emergency room or dentist?

Hospital emergency rooms in Saint Peters can manage spreading infection, trauma and pain, and they can prescribe medication, but most do not have a dentist on staff who can drain an abscess at the tooth, do a root canal or reattach a tooth.

If the problem is clearly specialised, the city also has 0 oral and maxillofacial surgeons, 2 endodontists (root canal specialists) and 0 pediatric dentists in our directory.

How to get a same-day appointment

  1. Call general dentists close to you as early in the day as possible and say it is urgent.
  2. Describe the problem clearly: pain level, swelling, bleeding and when it started.
  3. Ask about the cost of an emergency exam and X-ray before you go, and whether they take your insurance or Medicaid.
  4. If no one can see you and symptoms are getting worse, go to urgent care or an emergency room.
