A dental problem rarely arrives at a convenient time. You may wake with a swollen cheek, break a tooth during lunch, or notice that a dull ache has become impossible to ignore. The difficult question is often: “Can this wait?”
A dental emergency generally involves severe pain, active infection, significant injury, uncontrolled bleeding, or a risk of losing a tooth. Knowing the difference between an urgent problem and one that can wait can help you act without panicking.
For residents looking for emergency dental in London Ontario, the safest first step is to call a dental office, describe the symptoms clearly, and follow the team’s instructions. A phone conversation can help determine whether you need a same-day dental appointment, the next available visit, or emergency hospital care.
Common Dental Emergencies
Not every dental problem requires immediate treatment, but certain symptoms should never be ignored. Severe pain, swelling, uncontrolled bleeding, or dental injuries can quickly worsen without professional care. Below are some of the most common dental emergencies and the steps you should take if they happen.
Severe or Persistent Tooth Pain
A mild, short-lived sensitivity to cold does not always mean an emergency. However, tooth pain should be treated more urgently when it is severe, throbbing, constant, worsening, waking you from sleep, or making it difficult to eat.
Pain may come from decay, a damaged filling, a crack, inflammation inside the tooth, or an infection. Pain medicine may temporarily reduce discomfort, but it does not repair the cause. Call promptly when pain lasts, repeatedly returns, or occurs when biting.
Swelling, a Dental Abscess, or Signs of Infection
Swelling in the gums, face, jaw, or neck deserves prompt attention. A small pimple-like bump on the gum, a bad taste in the mouth, fever, tenderness under the jaw, or facial swelling may indicate an infection.
Dental infections do not reliably disappear on their own. They usually require treatment of the source, which may involve draining the infection, repairing the tooth, performing a root canal, or removing a tooth that cannot be restored.
Go to the nearest hospital emergency department or call 911 when swelling affects breathing or swallowing, spreads rapidly toward the eye or neck, or is accompanied by serious illness. These symptoms may involve the airway and should not wait for a routine dental visit.
A Knocked-Out Permanent Tooth
A knocked-out adult tooth is one of the most time-sensitive dental emergencies. Pick the tooth up by the crown—the white part you normally see—not by the root. If it is dirty, rinse it gently with cool water. Do not scrub it, use soap, or remove tissue attached to the root.
When it is safe and easy to do so, an adult can gently place the tooth back into the socket and hold it in position. If that is not possible, keep it moist in cold milk and bring it to the dentist immediately.
Never try to reinsert a baby tooth because doing so may damage the permanent tooth developing underneath.
Time matters. Call an emergency dentist while you are on the way so the clinic can prepare for your arrival.
A Chipped, Cracked, or Broken Tooth
A tiny chip with no pain may not require treatment within the hour, but it should still be checked. A larger break, visible crack, sharp edge, bleeding, or sensitivity to air and temperature is more urgent.
Rinse your mouth gently with water. Save any tooth fragments and bring them with you. If the area is bleeding, apply light pressure with clean gauze. A cold compress placed on the outside of the cheek may help reduce swelling.
A small chip may be repaired with a dental filling or bonding. A weakened tooth may need a dental crown, while deeper nerve damage may require root canal treatment.
Uncontrolled Bleeding or Significant Mouth Trauma
Bleeding after biting the tongue or lip often slows with steady pressure from clean gauze or a cloth. Bleeding that does not stop, heavy bleeding after an injury, a suspected broken jaw, or serious facial trauma requires immediate medical care.
Go to an emergency department when the injury extends beyond the tooth, involves loss of consciousness, causes difficulty opening or closing the jaw, or may have affected the head or neck. A dentist can treat damaged teeth, but a hospital is better equipped to assess major facial injuries and airway concerns.
A Lost Filling or Crown
A missing filling or crown is not always a medical emergency, but the exposed tooth can become painful and vulnerable to further damage. Call a dental office for advice, especially when there is strong sensitivity, a sharp edge, or pain when biting.
Keep the crown if you can find it. Do not glue it back with household adhesive. Until your appointment, avoid chewing on that side and stay away from very hard, sticky, hot, or cold foods.
Temporary dental cement from a pharmacy may sometimes protect the area, but it is not a permanent repair.
What Usually Can Wait for a Regular Appointment?
Not every dental concern needs immediate treatment. Minor sensitivity, a small painless chip, mild gum irritation, a slightly loose denture, or a cosmetic concern can often wait for a scheduled visit.
Do not ignore the problem indefinitely. Contact a dental clinic in London Ontario, explain your symptoms, and ask how soon you should be examined.
What to Do While Waiting for Your Appointment
First, call the clinic. Describe when the problem started, where the pain is located, whether swelling is present, and whether there was an injury. Mention fever, bleeding, difficulty swallowing, medication use, pregnancy, allergies, and important medical conditions.
You can gently rinse with warm salt water, use a cold compress on the outside of the face, and take an over-the-counter pain reliever that is normally safe for you, following the package directions.
Do not place aspirin or another pill directly against the gum because it can injure the tissue. Avoid applying heat to facial swelling.
A same-day dental appointment may be used to diagnose the source, relieve immediate symptoms, and prevent further damage. Final treatment may be completed that day or planned after an examination and any necessary X-rays.
Preparing for an Emergency Visit
Bring your insurance information, medication list, and any tooth fragments, crown, or appliance involved. Mention recent dental treatment completed elsewhere.
