A collapsible toothbrush, a disposable tooth flosser or a roll of floss isn’t difficult to fit into your purse or carry-on. “Floss is very compact, so you can take it with you when you travel,”
Depending on your destination, it might be a good idea to pack extra oral care supplies. They’ll come in handy if you run out and can’t buy replacements. Some hotels will stock disposable toothbrushes at the desk. Remember that in a pinch, without paste, you can still brush with water. You’ll still be removing plaque from your teeth, as long as you brush properly.
