Emergency Dentist in London, Ontario: What to Do When a Dental Crisis Hits

A cracked tooth on a Sunday evening. A lost filling the night before a big meeting. Unbearable jaw pain that keeps you awake at 2 a.m. If you have been there, you already know — a dental emergency does not ask for permission, and it certainly does not wait for regular office hours. Knowing exactly where to turn, and what to do in those first critical minutes, can be the difference between saving a tooth and losing it for good.

What Counts as a Dental Emergency? (And What Can Wait)

Not every dental issue demands you drop everything and rush to a clinic — but some absolutely do. Understanding the difference protects both your health and your wallet.

According to the Canadian Dental Association, a dental emergency is any condition that causes severe pain, risk of infection, significant bleeding, or permanent damage if not treated promptly.

Situations That Require an Emergency Dentist Immediately

• • Severe, persistent toothache that worsens with pressure or temperature

• • A knocked-out (avulsed) tooth — time is critical; ideally treated within 30 minutes

• • A cracked or fractured tooth with sharp pain or visible nerve exposure

• • Dental abscess with swelling, fever, or difficulty swallowing — can become life-threatening

• • Broken dental appliance cutting into your gums or cheek tissue

• • Uncontrolled bleeding in the mouth following trauma or extraction

• • Lost crown or filling exposing a sensitive or decayed tooth

• • Facial swelling extending below the jaw or toward the neck (seek ER care immediately)

Issues That Are Urgent But Not Immediately Critical

• • Minor chips or cracks with no pain

• • A lost filling or crown with mild sensitivity

• • Dull, intermittent toothaches that come and go

If you are unsure whether your situation qualifies, call Apple Tree Dental at (519) 641-1411 or visit our Contact page. Phone lines are open 8 AM to 9 PM for exactly this purpose.

First Aid Steps to Take Before You Reach the Emergency Dental Clinic

These first-aid steps are aligned with guidelines from the Canadian Dental Association and Health Canada. They can limit damage and manage pain while you arrange your emergency appointment.

For a Knocked-Out Adult Tooth

1. 1. Pick the tooth up by the crown (white part) — never by the root.

1. 1. Rinse it gently with clean water if dirty — do not scrub or use soap.

1. 1. Try to reinsert it into the socket, or keep it moist in milk or inside your cheek.

1. 1. Get to an emergency dentist within 30 minutes for the best chance of saving the tooth.

See our detailed guide: What to Do If a Tooth Gets Knocked Out

For Severe Toothache

• • Rinse with warm salt water to reduce inflammation and clear debris

• • Take an over-the-counter pain reliever such as ibuprofen (if not contraindicated)

• • Avoid applying aspirin directly onto the gum tissue — it can cause chemical burns

• • Place a cold compress on your cheek to reduce swelling (20 minutes on, 20 minutes off)

For a Dental Abscess

Do not delay this one. A dental abscess is a bacterial infection that can spread to your jaw, neck, and — in severe cases — your bloodstream (sepsis). According to Health Canada, untreated oral infections can become systemic within 24–48 hours. Call Apple Tree Dental immediately. If swelling is moving toward your throat or you have difficulty breathing, go directly to the nearest hospital emergency room.

For a Cracked or Fractured Tooth

• • Rinse your mouth with warm water

• • Apply a cold compress to minimize swelling

• • Avoid chewing on the affected side

Call Apple Tree Dental for a same-day assessment — cracks can worsen quickly and reach the nerve. Our team offers root canal therapy to save teeth that have been compromised by fractures.

Dental Emergencies and the Canadian Healthcare System: What You Need to Know

Many Canadians are surprised to learn that dental care is largely separate from the provincial health system. Unlike a visit to a walk-in medical clinic, dental emergencies are almost never covered by OHIP in Ontario — unless the procedure takes place in a hospital setting. You can confirm what OHIP covers at the Ontario Ministry of Health website.

This is precisely why having access to a walk-in dental clinic in London that accepts insurance plans — including the CDCP — is so important for Ontario residents. The gap in public dental coverage means that having a reliable private dental clinic relationship is one of the most practical steps you can take for your long-term health and financial wellbeing.

How to Prevent Dental Emergencies Before They Happen

Prevention is always the best strategy. According to the Canadian Dental Association, most dental emergencies result from untreated decay, missed cleanings, or minor damage left unaddressed. Regular visits to your dentist are the single most effective way to avoid a painful and costly emergency.

Practical Prevention Tips for Canadian Patients

• • Schedule professional cleanings and check-up exams at least twice per year

• • Wear a custom-fitted mouthguard if you play contact sports — generic guards offer far less protection

• • Avoid using your teeth as tools to open packaging, bottles, or blister packs

• • Address tooth sensitivity early — it is often a sign of underlying decay or a cracked filling

• • Replace old, weakened fillings before they crack under normal chewing pressure

• • Stay hydrated — chronic dry mouth dramatically increases the risk of decay and gum disease

• • If you grind your teeth at night (bruxism), ask your dentist about a custom nightguard

• • Limit acidic foods and beverages that erode enamel over time

Patients who visit Apple Tree Dental regularly for check-ups and cleanings are far less likely to experience sudden, painful emergencies. Book your next preventive appointment today.
