Shelves at Walgreens and other local drugstores have been empty for weeks. There are other brands, but Reach is a big part of this market.
Johnson & Johnson, the New Jersey-based consumer products company that makes this brand of floss, confirmed the delays.
"The timing of shipments of Reach dental floss was delayed," spokeswoman Jodie Wertheim said in an e-mail.
But good dental hygiene isn't going to suffer, she assured.
"We are now shipping product on an expedited schedule," she said.
