Toothpaste for dentin hypersensitivity fluoride role and selection
Use a fluoride toothpaste formulated for sensitivity and brush gently; active ingredients vary by cause.
The short answer
Sensitivity occurs when exposed dentin tubules transmit stimuli toward the pulp.
What can expose dentin beneath the enamel or gums?
Wear, erosion, recession, abrasion, and cracks can expose dentin, so toothpaste may not cure the cause.
How can you use toothpaste to manage sensitivity?
Use a soft brush, light pressure, and sensitivity toothpaste consistently.
When does tooth sensitivity need a dental examination?
A single sensitive tooth, crack, decay, or persistent pain needs examination.
What should you ask about sensitivity toothpaste options?
Ask which ingredient fits the diagnosis and whether bonding or varnish is needed.
