What to Do in a Dental Emergency: A Step-by-Step Guide

Dental emergencies do not schedule themselves around convenient moments. They happen at dinner, on a Saturday morning, in the middle of a work trip. Knowing what to do in those first critical minutes (before you reach a dentist) can make the difference between saving a tooth and losing one.

This guide covers the most common dental emergencies and what to do for each.

What Counts as a Dental Emergency?

Not every dental problem requires immediate attention, but the following situations do:

• Severe or sudden tooth pain that does not subside
• A tooth that has been knocked out
• A cracked or fractured tooth, especially with pain or sensitivity
• A dental abscess (swelling in the gum or jaw, sometimes accompanied by fever)
• A lost or broken crown, filling, or bridge that is causing pain or exposing sharp edges
• Soft tissue injury (lacerations to the tongue, cheek, or gums that are bleeding heavily)

If you are experiencing severe swelling that is affecting your ability to breathe or swallow, go to an emergency room immediately. This is the one situation where a dental office is not the right first call.

A Knocked-Out Tooth

A knocked-out permanent tooth is one of the few dental situations where time is genuinely critical. The window for successful reimplantation is typically 30 to 60 minutes.

• Pick up the tooth by the crown, not the root. Touching the root damages the cells needed for reimplantation.
• Rinse gently with water if it is dirty. Do not scrub it, use soap, or wrap it in a tissue.
• Keep it moist. If possible, place the tooth back in its socket and hold it there. If that is not feasible, store it in a glass of milk or hold it between your cheek and gum.
• Call the office immediately. Same-day emergency care is available. Call (201) 670-0670.

Do not attempt to reimplant a knocked-out baby tooth. In children, the priority is to keep the child calm, control any bleeding, and call the dentist for guidance.

Severe Tooth Pain

Sudden, intense tooth pain usually signals an infection that has reached the pulp of the tooth, or a dental abscess. Neither resolves on its own.

• Rinse with warm salt water. This can reduce inflammation and provide temporary relief.
• Take an over-the-counter pain reliever. Ibuprofen is generally more effective than acetaminophen for dental pain due to its anti-inflammatory properties. Do not place aspirin directly on the gum or tooth.
• Apply a cold compress to the outside of the cheek. 20 minutes on, 20 minutes off.
• Call the office as soon as it opens. Severe tooth pain warrants same-day care.

If you notice swelling in your jaw, face, or neck alongside the pain, or if you develop a fever, call the office immediately. A spreading dental infection is a medical urgency.

A Cracked or Broken Tooth

A minor chip may not be painful and can wait for a routine appointment. A crack that extends toward the pulp or causes sharp pain when biting needs prompt attention.

• Rinse with warm water. This cleans the area and can reduce discomfort.
• Apply gauze if there is bleeding. Hold gentle pressure for 10 minutes.
• Cover sharp edges. Dental wax from a pharmacy can temporarily protect the inside of your cheek or tongue from a jagged edge.
• Avoid chewing on that side. Until you are seen, avoid hard or sticky foods on the affected tooth.

A Lost or Broken Crown or Filling

Losing a crown or filling is not usually painful right away, but the exposed tooth structure is vulnerable to temperature, pressure, and bacteria.

• Keep the crown if you can find it. Bring it to your appointment. In some cases it can be recemented.
• Apply clove oil or dental cement from a pharmacy. These can temporarily seal and protect the tooth.
• Avoid sticky or hard foods until the crown or filling is replaced.
• Call the office. This can often be addressed same-day.

A Dental Abscess

An abscess is a pocket of infection that forms in the gum or at the root of a tooth. It presents as a painful, swollen area (sometimes with a visible bump on the gum) and may be accompanied by throbbing pain, sensitivity to heat, and general malaise.

An abscess will not resolve without treatment. Rinsing with salt water can provide temporary relief, but the underlying infection requires either a root canal or extraction. Call the office for same-day care.
