Toothaches & Sensitivity
Why do I have tooth pain or sensitivity, and what should I do?
Toothaches and sensitivity are common but they are always worth paying attention to. Pain that lingers, wakes you up, or comes with swelling often signals a problem that needs prompt attention. A brief phone call can help us triage whether you should come in today or wait for a scheduled visit.
If you experience facial swelling, difficulty breathing or swallowing, or swelling extending toward your neck or eye, go to your nearest emergency room immediately.
Common types of tooth sensitivity
- Brief cold sensitivity
A sharp twinge that fades quickly when exposed to cold food or drink. Often related to enamel wear or exposed root surfaces.
- Lingering sensitivity to heat, cold, or sweetness
Pain that lasts more than a few seconds after the stimulus is removed may indicate a deeper issue affecting the pulp of the tooth.
- Sharp pain when biting
Biting sensitivity can point to a cracked tooth, a loose filling, or early signs of infection.
- Spontaneous or throbbing pain
Pain that occurs without an obvious trigger (especially if it throbs or wakes you at night) often signals inflammation or infection inside the tooth.
Common causes
Tooth pain and sensitivity have many possible causes, and the right treatment depends on identifying the root cause at your appointment:
- Enamel wear (from acidic foods, drinks, or grinding)
- Exposed root surfaces due to gum recession
- Cavities (dental caries)
- Cracked or fractured teeth
- Gum infection or abscess
- Bruxism (teeth grinding or clenching, often during sleep)
What to do before your appointment
- Take over-the-counter pain relief (ibuprofen or acetaminophen) as directed on the package to manage discomfort.
- Avoid very hot, cold, or sweet foods and drinks that trigger your pain.
- Do not place aspirin or other medication directly on the gum or tooth, this can cause chemical burns to the soft tissue.
- If there is visible swelling of the face or jaw, call us immediately, this may indicate a spreading infection that requires prompt care.
When to call right away
Call us at 905-737-0600 as soon as possible if you experience any of the following:
- Swelling of the face, jaw, or neck
- Fever alongside dental pain
- Difficulty opening your mouth fully
- Pain severe enough to prevent sleep
For dental emergencies, we aim to see you the same day. If symptoms involve difficulty breathing or swallowing, or swelling extending toward the eye or neck, go directly to your nearest emergency room.
If tooth pain is the result of a deeper infection, a root canal may be recommended to save the tooth and eliminate the source of pain.
