I Can't Believe It's Not Toothpaste! Poison Control Center Calls Regarding Dental and Oral-Care Products

A cluster of incidents in which non-tooth-paste products were used to brush teeth prompted a review of all calls to one Poison Control Center (PCC) regarding exposures to dental and oral-care products to determine if any resulted in significant toxicity.

Retrospective review of 65,849 calls to one PCC during one calendar year. All inquiries about exposures to substances used as dental or oral-care products were analyzed by a single reviewer for reported adverse effects; including hospital admission or PCC referral for emergent medical evaluation.

798 calls involved exposure to dental or oral-care products, comprising 1.21 % of all calls received. Toothbrushing incidents with non-toothpaste products (122 cases) did not result in any significant recognized toxicity. Twenty-four patients were either referred for emergent medical evaluation (14) or were admitted to the hospital (10). In 23 of these patients (96%), the toxic agent was either an over-the-counter analgesic or a local anesthetic used to treat dental pain.

Among PCC calls received regarding dental and oral-care products, over-the-counter analgesics and local anesthetics used for dental pain resulted in the most frequent need for emergent medical evaluation or for hospital admission.
