A broken tooth is never pleasantbut when it results in an exposed nerve, the situation becomes significantly more urgent. This type of injury often causes sharp, radiating pain, extreme sensitivity, and a high risk of infection. Immediate first aid and fast professional attention are crucial to protect the tooth and relieve discomfort.
At McLevin Dental Clinic, we treat dental emergencies throughout Scarborough, including fractured teeth and nerve exposure. In this guide, you’ll learn what to do right after the injury, how to manage pain, and when to seek emergency dental care.
Why Exposed Nerves Are a Dental Emergency
When a tooth breaks and reveals the inner pulp or nerve tissue, the protective enamel and dentin layers are no longer shielding the tooth. This means:
Bacteria can enter directly, increasing infection risk
Pain becomes intense, especially with temperature changes or pressure
The tooth structure becomes unstable
Delaying treatment can lead to nerve death or tooth loss
An exposed dental nerve is not something that will heal on its own. Fast action is necessary to avoid more serious complications like abscesses or the need for extraction.
Signs Your Tooth Has an Exposed Nerve
Not all broken teeth involve nerve exposure, but the following symptoms strongly indicate it:
Intense, throbbing tooth pain
Sharp sensitivity to hot, cold, sweet, or air
Visible red or pink tissue inside the broken tooth
Pain that worsens when biting down
Swelling or bleeding around the tooth or gums
Discomfort that radiates to the jaw, ear, or head
If any of these symptoms appear, assume the nerve is involved and treat the situation as a dental emergency.
First Aid for a Broken Tooth with Exposed Nerve
While you wait for emergency care, taking proper first-aid steps can reduce pain and prevent further damage:
1. Rinse Gently with Salt Water
Use warm salt water (½ tsp salt in 1 cup of water) to rinse the mouth. This cleans the area and helps reduce bacterial presence. Avoid swishing aggressively, which can worsen pain or bleeding.
2. Control Bleeding
If the break is accompanied by bleeding, gently apply sterile gauze with light pressure. Most minor oral bleeding subsides within 1015 minutes.
3. Protect the Exposed Nerve
If possible, cover the exposed area using:
Dental wax
Temporary dental filling material (available at pharmacies)
Sugar-free gum as a last resort
Do not press hard or attempt to reshape the tooth. The goal is to create a soft barrier to prevent air and debris from touching the nerve.
4. Apply a Cold Compress
Place an ice pack on the outside of the cheek near the injury site. This helps reduce swelling and numbs the area naturally.
5. Take Over-the-Counter Pain Medication
Ibuprofen or acetaminophen can relieve pain temporarily. Follow dosage instructions carefully, and never apply aspirin directly to the gums or toothit can cause chemical burns.
What Not to Do
Avoid these common mistakes that can worsen the situation:
Do not use glue, tape, or household adhesives to fix the tooth
Do not eat or chew on the affected side
Do not touch the nerve area with your tongue or fingers
Do not delay treatment beyond 24 hours
An exposed nerve is highly vulnerable, and time is of the essence.
When to Call McLevin Dental Clinic
You should seek emergency dental care immediately if:
You have severe tooth pain or nerve exposure
The broken tooth leaves a visible hole or red tissue
Pain worsens or spreads
There is swelling or signs of infection
The tooth becomes loose or mobile
We offer same-day emergency dental services in Scarborough, including pain relief, root canal therapy, temporary restorations, and full tooth repair.
How We Treat a Tooth with an Exposed Nerve
Depending on the severity of the break and the condition of the nerve, treatment options include:
1. Root Canal Therapy
If the nerve is damaged or infected, a root canal will remove the inflamed tissue, clean the canal, and seal it to prevent reinfection. This restores comfort and saves the natural tooth.
2. Direct Pulp Capping (in some cases)
If the nerve is exposed but not infected, we may apply a special material to protect it and allow healing, followed by a permanent filling or crown.
3. Dental Crown Placement
Once the tooth is stabilized, a custom dental crown will be used to restore its shape, function, and appearance.
4. Tooth Extraction (only if necessary)
If the tooth cannot be saved, we will discuss extraction and replacement options such as dental implants or bridges.
At McLevin Dental Clinic, we tailor treatment to the patients specific needs with a focus on preserving natural teeth whenever possible.
Preventing Tooth Breakage and Nerve Exposure
While accidents cant always be avoided, the following steps can reduce your risk:
Avoid chewing on hard foods (ice, hard candy, unpopped popcorn kernels)
Wear a custom sports mouthguard during high-impact activities
Treat teeth grinding (bruxism) with a nightguard
Address decay or weakened teeth early before they fracture
Maintain regular dental checkups to catch vulnerabilities before they lead to emergencies
