What is the direct answer?
What does this question mean?
Dentine contains microscopic tubules leading toward the pulp. When enamel is worn, a root surface is exposed, or a gumline recedes, fluid movement in those tubules can stimulate the tooth nerve.
What can you do next?
Use a soft brush and low pressure, avoid abrasive scrubbing, and use a sensitivity toothpaste consistently as directed. A dentist may apply fluoride or a desensitising material, repair a defect, or treat decay depending on the cause.
When should you seek dental care?
Seek care if pain lingers after the trigger, occurs without a trigger, hurts when biting, or affects one tooth. These features can indicate decay, a crack, pulp inflammation, or another condition rather than simple sensitivity.
What should you ask the dentist?
Ask whether enamel loss, recession, decay, a crack, or grinding explains the symptom. Ask which desensitising treatment is suitable and whether the bite or a filling needs attention.
Frequently asked questions
Can home care replace an examination?
No. It can reduce irritation and plaque, but persistent or severe symptoms need a cause-focused assessment.
What may a dentist check?
The clinician may inspect the gums and teeth, test sensitivity or biting, and use imaging when the findings require it.
