Dentinal Hypersensitivity: A Review
Over-the-Counter Products

Over-the-counter products for the treatment of tooth sensitivity are considered to be a simple and cost-effective first line of treatment for most patients.¹⁸ The primary at-home non-invasive treatment option has historically been anti-sensitivity dentifrices. The two most common ingredients are potassium nitrate, which interferes with the transmission of the nerve impulse, and stannous fluoride, which blocks dentinal tubules by forming a smear layer at the surface. Recently, a novel strip product has been introduced which provides fast, targeted sensitivity relief by occluding dentinal tubules with oxalate crystals.
