What to Do in a Dental Emergency: A Quick Guide

Dental emergencies are stressful, but knowing what to do can make the difference between saving and losing a tooth. Here is a quick guide to the most common dental emergencies.

Knocked-Out Tooth

Pick up the tooth by the crown (not the root). If dirty, rinse gently with milk. Try to reinsert it into the socket if possible. If not, keep it in milk and get to a dentist within 30 minutes.

Severe Toothache

Rinse your mouth with warm salt water. Use dental floss to remove any trapped food. Take over-the-counter pain relief (not aspirin directly on the gum). Contact your dentist as soon as possible.

Broken or Chipped Tooth

Save any pieces. Rinse your mouth with warm water. Apply a cold compress to reduce swelling. See your dentist urgently — we can often repair the tooth on the same day.

Lost Filling or Crown

Keep the crown if you have it. You can temporarily reattach it with denture adhesive or toothpaste. Avoid chewing on that side and see your dentist promptly.

When to Go to A&E

Go to the hospital if you have uncontrolled bleeding, difficulty breathing or swallowing, or if the injury involves facial bones.

Prevention

Wearing a mouthguard during sports, avoiding chewing ice or hard sweets, and maintaining regular dental visits all help prevent emergencies.
