Alisa Kauffman, DMD, has been handing out free masks for weeks, ABC 7 reports.
"It's just a simple surgical mask, the ones all dentists use commonly," Dr. Kauffman, a New York City-based dentist, said.
Dr. Kauffman, who usually makes house calls to the homebound elderly, urged caregivers in early March to start wearing a mask and eventually began giving them away.
The dentist has given out hundreds of masks, each bagged and dangling at the end of a long pole. Dr. Kauffman said she will continue giving out masks until she runs out.
