Carry-on details
Allowed. Dental floss — string floss, dental tape, or floss picks — isn't a liquid, gel, or restricted sharp item, so it has no quantity limit and doesn't need to be declared at the checkpoint.
Checked-bag details
Allowed in any quantity, with no special packing requirement.
FAQ
- Are floss picks with a small plastic pick allowed on a plane?
- Yes. The plastic pick on a floss pick isn't sharp or rigid enough to be treated as a prohibited item, so floss picks travel the same as regular string floss.
- Does dental floss need to go in my liquids bag?
- No. Floss isn't a liquid, gel, or aerosol, so it can stay in your toiletry bag or carry-on without being packed with your 3.4 oz liquids.
