Do Cavities Hurt?
No, not all cavities cause pain. While many associate cavities with toothaches, the reality is more nuanced. The experience of pain from a cavity varies greatly depending on the size and location of the decay.
- Early Stages: Small cavities often cause no pain or only mild sensitivity to hot, cold, sweet, or acidic foods and drinks. This is because the decay hasn't reached the inner layers of the tooth where the nerves reside. [Source: Listerine, Sensodyne]
- Advanced Stages: As the cavity progresses and reaches the dentin (the layer beneath the enamel), pain becomes more likely. This pain can range from mild to severe, depending on the extent of the decay and the individual's sensitivity. [Source: Medical News Today]
- Severe Cases: In advanced cases, the cavity may reach the pulp (the innermost part of the tooth containing nerves and blood vessels), resulting in a throbbing toothache. An abscess, a pocket of pus, can also form, potentially causing intense pain.

It's important to note that the absence of pain doesn't mean a cavity isn't present. Regular dental checkups are essential for early detection and prevention of cavities, regardless of the presence or absence of pain. [Source: Mayo Clinic, Dental Health Society]
Symptoms Beyond Pain
While pain is a common symptom, other warning signs might indicate a cavity:
- Tooth Sensitivity: Increased sensitivity to temperature changes or sugary foods and drinks.
- Discoloration: A dark spot or stain on the tooth surface.
- Visible Holes: Small holes or pits may be visible on the tooth surface.
When to See a Dentist
If you experience any of the above symptoms, even without pain, it's crucial to consult a dentist for a thorough examination. Early detection and treatment are key to preventing more severe problems and preserving your tooth health. [Source: Cleveland Clinic]
