A dental emergency can happen without warning, and knowing what to do before one occurs makes a meaningful difference in how things turn out. Whether a tooth gets knocked out during a sports game, a molar cracks on something hard, or a swollen jaw wakes you at two in the morning, having a plan means faster action, less pain, and a better chance of saving the tooth. This guide covers the most common dental emergencies, what to do in the first few minutes, and when heading to the emergency room is the right call.
Our team at Newton Smile Centre provides emergency dental care in Newton, MA for patients who need same-day attention. If you are experiencing a dental emergency, call our office first so we can prepare for your arrival and give you guidance over the phone.
Knocked-Out Permanent Tooth
A knocked-out permanent tooth is one of the most time-sensitive dental emergencies. There is roughly a 30-minute window during which a dentist may be able to successfully replant the tooth, so every minute matters.
Pick the tooth up by the crown, which is the visible white portion at the top, and avoid touching the root entirely. Rinse it gently with water or milk without scrubbing. The best option is to gently reposition it in the socket yourself and bite down softly to hold it in place. If that is not possible, keep it submerged in a small container of milk or hold it tucked inside your cheek between your gum and lip. Get to a dentist immediately. Do not let it dry out, and do not wrap it in a paper towel or cloth.
A Knocked-Out Baby Tooth
A knocked-out baby tooth is handled differently. Dentists generally do not replant baby teeth because doing so risks damaging the developing permanent tooth underneath. Call our office and we will guide you on what to do next, but this situation is typically less urgent than a knocked-out permanent tooth.
Broken, Cracked, or Chipped Tooth
A broken tooth ranges from a minor chip along the edge to a full fracture exposing the inner pulp. The severity determines the urgency. If you have significant pain, bleeding, or a large piece of the tooth has broken away, come in the same day. If the break is small and painless, you still need an appointment soon but can likely wait a day or two.
Collect any broken pieces and store them in milk. Rinse your mouth gently with warm water and apply a cold compress to the outside of your cheek if there is swelling. Over-the-counter dental wax can temporarily cover sharp edges to protect the inside of your lip and tongue.
Do not ignore small cracks. A fracture that appears minor can extend deeper over time, eventually reaching the nerve and requiring root canal therapy, or splitting the tooth entirely. Early treatment is almost always simpler and less costly than waiting.
Lost Filling or Crown
Losing a filling or crown exposes the tooth to bacteria, temperature sensitivity, and further breakdown. It is not usually a true emergency, but it should not be ignored for long.
If a crown falls off, clean it gently and keep it in a safe container. Temporary dental cement, available at most pharmacies, can be used to seat the crown back temporarily until your appointment. Do not use household glue. Call our office to schedule a repair. We offer same-day crowns using CEREC technology, which means your tooth can be fully restored in a single visit without waiting days for a lab.
Dental Abscess
A dental abscess is an infection that forms inside the tooth or in the surrounding gum tissue. It can appear as a swollen, pimple-like bump on the gum, or it can cause widespread swelling in the jaw, cheek, or neck. A dental abscess is always an emergency.
Left untreated, a dental infection can spread to the jaw, neck, and, in rare cases, to areas of the head and airway, where it can become life-threatening. If you have swelling that is spreading beyond the jaw, difficulty breathing or swallowing, or a fever alongside tooth pain, go to the emergency room immediately. If the swelling is localized to the gum or tooth area, call our office for same-day care.
Do not place aspirin directly on the tooth or gum because direct contact with aspirin can cause chemical burns to the tissue. Over-the-counter pain medication taken by mouth can help manage discomfort while you arrange care.
Soft Tissue Injuries
Cuts, lacerations, or puncture wounds to the lips, tongue, cheeks, or gums should be rinsed gently with clean water. Apply steady, gentle pressure with a clean cloth or gauze to control bleeding. If bleeding does not slow within 15 minutes of continuous pressure, go to the emergency room.
Biting the inside of the cheek or lip hard enough during a fall or sports impact can look alarming but often heals on its own with proper care. Monitor the area, and schedule an appointment if healing does not progress normally within a couple of days.
ER vs. Dental Office: How to Decide
Knowing which facility to go to saves time and gets you the right care faster. Emergency rooms can manage pain, prescribe antibiotics, and stabilize a serious infection, but they cannot perform dental procedures. You will always need to follow up with a dentist for the underlying tooth issue.
- Go to the emergency room for jaw swelling spreading toward the throat or neck, difficulty breathing or swallowing, uncontrolled bleeding that is not slowing with pressure, or signs of serious systemic infection such as high fever, chills, or confusion.
- Call a dentist first for knocked-out or broken teeth, dental abscesses without systemic symptoms, lost fillings or crowns, dental pain without fever or spreading swelling, and soft tissue injuries that are not bleeding heavily.
When in doubt, call us. We can help you assess urgency over the phone and direct you to the right level of care without delay.
What to Keep in a Dental Emergency Kit
A small kit at home can make a real difference in a dental emergency. Consider keeping the following on hand:
- Dental cement or temporary filling material for covering an exposed cavity or reseating a crown temporarily
- Gauze pads for controlling bleeding from a tooth socket or soft tissue wound
- A small sealed container for storing a knocked-out tooth in milk
- Over-the-counter pain reliever appropriate for adults or children in your household
- Your dentist’s emergency contact number saved in your phone so you are not searching during a stressful moment
Preparation does not prevent emergencies, but it does ensure you respond correctly in the critical first minutes. Contact Newton Smile Centre today to establish care so that if an emergency does occur, you have a trusted team ready to help you.
Frequently Asked Questions About Dental Emergencies
What should I do if a permanent tooth gets knocked out?
Pick the tooth up by the crown and avoid touching the root. Rinse it gently with water or milk without scrubbing. Try to place it back in the socket and bite down softly to hold it. If that is not possible, keep it submerged in milk or tucked inside your cheek. Get to a dentist within 30 minutes for the best chance of successful replantation.
Is a dental abscess a dental emergency?
Yes. A dental abscess is always an emergency because the infection can spread beyond the tooth and gum into the jaw and other areas of the head. Call your dentist the same day. If you experience jaw swelling spreading toward your throat, difficulty swallowing, trouble breathing, or a high fever, go to the emergency room immediately rather than waiting for a dental appointment.
How do I know whether to go to the ER or the dentist for a dental emergency?
Go to the emergency room for swelling spreading to the neck or throat, difficulty breathing or swallowing, uncontrolled bleeding, or signs of systemic infection like high fever or confusion. Call a dentist for knocked-out teeth, broken teeth, lost crowns or fillings, and localized dental pain. Emergency rooms can stabilize infections and prescribe medication but cannot perform dental procedures, so a dentist follow-up is always needed.
Can a lost filling or crown wait until a regular appointment?
For a short time, yes, though you should call your dentist and schedule an appointment promptly. Temporary dental cement from a pharmacy can protect the exposed tooth and reseat a crown in the meantime. Waiting too long leaves the tooth vulnerable to bacteria, temperature sensitivity, and further breakdown, so prompt repair within a few days is best.
What should I keep in a dental emergency kit at home?
A basic dental emergency kit includes dental cement or temporary filling material, gauze pads for bleeding control, a small sealed container for storing a knocked-out tooth in milk, an over-the-counter pain reliever appropriate for your household, and your dentist’s emergency contact number saved in your phone. Being prepared means you can respond correctly in the first critical minutes of any dental emergency.
