Quick, sharp, and gone in seconds
This usually means exposed dentin at the gumline from recession or enamel abrasion. Potassium nitrate toothpaste used consistently for two weeks, a soft brush, and in-office fluoride varnish resolve most cases.
Sharp pain on biting
Pain when releasing a bite often signals a cracked tooth or a failing filling. Cracks worsen, so this deserves an exam rather than watchful waiting.
Lingering ache after hot or cold
Pain that continues for 30 seconds or more after the stimulus is removed suggests irreversible pulp inflammation, which typically means root canal treatment. Waiting turns a straightforward appointment into an emergency.
Acid erosion
Sparkling water, citrus, wine, and reflux thin enamel over time. Rinse with plain water after acidic drinks and wait 30 minutes before brushing.
Key takeaways
- •Duration of the pain is the best diagnostic clue.
- •Lingering pain needs prompt evaluation.
- •Desensitizing toothpaste needs two consistent weeks to work.
