A toothache that will not go away is your body’s way of saying something is seriously wrong. It is not something to sleep on or push through with pain relief alone. If the pain is sharp, throbbing, or getting worse, it could be a sign of a problem that needs urgent attention. Getting emergency dentistry near you as soon as possible can make the difference between saving a tooth and losing it altogether.
What Causes a Severe Toothache?
Not all toothaches are the same. A mild ache after eating something cold is very different from a deep, pounding pain that keeps you up at night. A severe toothache usually points to something that goes beyond surface-level sensitivity.
Here are the most common causes:
Tooth Decay Reaching the Nerve
A cavity starts small. Left untreated, it grows deeper, eventually reaching the soft inner pulp of the tooth where the nerve lives. Once decay reaches the nerve, the pain becomes intense and persistent. This is one of the most common reasons people seek emergency dental care.
Dental Abscess
An abscess is an infected collection of pus that can be at the root of a tooth or around the gum. This can happen when bacteria get inside the tooth through damage like a crack, decay, or gum disease.
An abscessed tooth causes the following:
- Severe, throbbing pain that does not stop
- Swelling in the face, jaw, or neck
- Fever and a general feeling of being unwell
- A bad taste in the mouth
- Sensitivity to pressure when biting
A dental abscess is a serious condition. The infection can spread beyond the mouth if left untreated—making prompt care essential.
Cracked or Fractured Tooth
A cracked tooth is not always visible. But it can cause sharp, shooting pain — especially when biting down or releasing pressure. Cracks can happen from biting hard food, grinding teeth at night, or an old filling that has weakened the tooth structure over time.
Impacted Wisdom Tooth
Wisdom teeth that do not have enough room to come through properly can become impacted—stuck beneath the gum or pushing against neighbouring teeth. This causes significant pain and pressure at the back of the mouth, often accompanied by swelling and difficulty opening the mouth fully.
Damaged or Lost Filling
When a filling cracks, falls out, or wears down, the inner part of the tooth becomes exposed. This can cause sudden and intense sensitivity—particularly to temperature and pressure.
Gum Disease in Advanced Stages
Advanced gum disease — periodontitis — can cause deep, persistent aching around the teeth and gums. As the supporting bone and tissue break down, teeth can become loose and extremely sensitive.
When Is a Toothache a Dental Emergency?
Not every toothache requires an emergency visit. But some situations genuinely cannot wait for a routine appointment.
Seek care from a dentist near you right away if you experience:
- Pain that is severe, constant, and does not improve with over-the-counter pain relief
- Swelling in the face, jaw, cheek, or neck
- A fever alongside tooth pain
- Difficulty breathing or swallowing
- A knocked-out or partially dislodged tooth
- A tooth that has cracked deeply after an injury
- Bleeding that does not stop after 15 to 20 minutes
- Numbness in the tooth after severe pain—this can mean the infection has spread
Any swelling that extends to the neck or affects your breathing is a medical emergency. Go to your nearest emergency room immediately in that situation.
What Happens at an Emergency Dental Appointment?
Walking into an emergency dental visit feeling anxious is completely normal. Here is what to expect:
| Stage | What Happens |
| Arrival and assessment | You describe your symptoms and pain level |
| Examination | The dentist checks the affected area carefully |
| X-rays | Images help identify the root cause of the pain |
| Diagnosis | The dentist explains what is causing the pain |
| Immediate treatment | Pain relief and urgent care are provided |
| Follow-up plan | Next steps are clearly discussed with you |
The goal of an emergency appointment is first to relieve your pain — and then to address the underlying cause.
What Can You Do While Waiting for Your Appointment?
If you are in pain and waiting to see a dentist in Edmonton, here are some steps that may help in the meantime:
- Take over-the-counter pain relief as directed on the packaging
- Rinse gently with warm salt water to reduce inflammation
- Apply a cold compress to the outside of your cheek—15 minutes on, 15 minutes off
- Avoid very hot, cold, or sweet foods and drinks
- Do not place aspirin directly on the gum—this can cause tissue damage
- Try to keep your head elevated, especially when lying down
These steps can reduce discomfort temporarily — but they are not a substitute for professional dental care.
How Are Severe Toothaches Treated?
Treatment depends entirely on what is causing the pain. Here is a simple overview:
- Deep cavity — a filling, crown, or root canal treatment, depending on the extent of decay
- Dental abscess — draining the infection, antibiotics, and root canal or extraction if necessary
- Cracked tooth—bonding, a crown, or extraction, depending on the severity of the crack
- Impacted wisdom tooth — monitoring, medication, or extraction if the tooth is causing ongoing problems
- Lost filling — replacement filling or crown to protect the exposed tooth
- Advanced gum disease — deep cleaning, medication, and an ongoing treatment plan
Every situation is different. Your dentist will explain the most appropriate option for your specific case clearly and honestly.

Frequently Asked Questions
Q1. Can a severe toothache go away on its own?
The pain may ease temporarily, but the underlying cause will not resolve without treatment — and delaying care usually allows the problem to worsen.
Q2. How quickly should I see a dentist for a toothache?
If the pain is severe, constant, or accompanied by swelling or fever, you should seek dental care on the same day — do not wait for a routine appointment.
Q3. Can a toothache cause other health problems?
Yes, a dental abscess left untreated can spread infection to the jaw, neck, or even the bloodstream, which can become a serious health issue.
Q4. What pain relief is safe to take for a toothache?
Over-the-counter options like ibuprofen or acetaminophen can help manage pain temporarily — always follow dosage instructions and consult a pharmacist if you are unsure.
