Tooth sensitivity is a common issue that many people experience from time to time. Often triggered by hot, cold, sweet, or acidic foods, it usually points to worn enamel or minor gum recession. But what if the pain becomes sharp, persistent, or unbearable? In some cases, tooth sensitivity is more than just discomfortits a sign of a dental emergency that requires immediate care.
At McLevin Dental Clinic, we help patients in Scarborough identify whether their tooth sensitivity is routine or an urgent problem. In this guide, well break down the causes of sensitivity, warning signs that require urgent dental attention, and what to do if the pain becomes severe.
What Causes Tooth Sensitivity?
Tooth sensitivity typically results from exposed dentinthe inner layer of your toothcaused by:
Enamel erosion from acid wear or aggressive brushing
Receding gums revealing the root surface
Cavities or tooth decay
Worn or damaged fillings
Cracked or chipped teeth
Teeth grinding (bruxism)
Recent dental procedures like whitening or fillings
While these causes are usually manageable with routine care, sudden or worsening sensitivity may signal a more serious issue.
Signs That Sensitivity Is an Emergency
Not all tooth sensitivity needs emergency treatment, but if you notice any of the following, you should contact McLevin Dental Clinic right away:
1. Sudden, Intense Pain
If the sensitivity turns into sharp, stabbing painespecially while eating, drinking, or breathing cold airit could indicate a deep cavity, cracked tooth, or exposed nerve.
2. Pain That Doesnt Go Away
Lingering sensitivity that lasts more than 30 seconds after a stimulus (hot, cold, sweet) often points to pulp inflammation or infection inside the tooth.
3. Visible Damage or Tooth Fracture
A chipped, cracked, or broken tooth exposing the inner layers can cause intense sensitivity. Delaying care may lead to infection or tooth loss.
4. Swelling or Gum Discoloration
If your gums appear red, swollen, or are bleeding around the sensitive tooth, this may be a sign of gum infection or abscess, which needs immediate treatment.
5. Sensitivity After Trauma or Accident
Any tooth sensitivity that begins after a fall, blow to the face, or accident should be evaluated quicklyeven if theres no visible damage.
What to Do Before You Reach the Dentist
If youre dealing with sudden or severe sensitivity, heres how to minimize pain and protect the tooth while waiting for professional care:
? Rinse with Warm Salt Water
Helps clean the area and soothe irritated gum tissues. Mix ½ tsp salt in a cup of warm water.
? Avoid Hot, Cold, or Sugary Foods
These can worsen the pain. Stick to room-temperature, soft foods until the sensitivity is evaluated.
? Take Over-the-Counter Pain Relievers
Use ibuprofen or acetaminophen as needed to manage painbut never place aspirin directly on the tooth or gums.
? Use Desensitizing Toothpaste (If Mild)
If the pain is not severe, brushing gently with toothpaste for sensitive teeth may offer temporary relief.
? Do Not Chew on the Affected Side
Give the area a rest until a dentist determines the cause and provides a treatment plan.
How McLevin Dental Clinic Treats Emergency Tooth Sensitivity
Our emergency dental care team will first conduct a thorough examination to identify the root cause. Based on the diagnosis, treatment may include:
? Dental Fillings
If a cavity or worn filling is causing the sensitivity, well restore the tooth with a new filling.
? Fluoride Treatments
Fluoride helps remineralize weakened enamel and reduce nerve exposure.
? Desensitizing Agents or Sealants
We can apply professional-grade desensitizing compounds to protect exposed areas of the tooth.
? Root Canal Therapy
If sensitivity is due to nerve inflammation or infection (pulpitis), a root canal can relieve pain and save the tooth.
? Dental Crowns
Severely cracked or damaged teeth may require a crown to restore strength and insulation.
? Gum Treatment
If recession or gum disease is the cause, we offer scaling, root planing, and soft tissue management to reduce sensitivity long-term.
How to Prevent Sudden Tooth Sensitivity
To reduce your risk of emergency-level sensitivity:
Use a soft-bristled toothbrush and gentle brushing technique
Avoid acidic foods and drinks like citrus, soda, and vinegar
Wear a nightguard if you grind your teeth
Visit your dentist twice a year for cleanings and checkups
Dont delay treatment for minor tooth discomfort
Treat dry mouth if present, as saliva helps protect enamel
