Check the box, tube crimp, or back of the tube for a printed date
Look for terms like “EXP,” “Best By,” “Use By,” or a lot code
Read the date format carefully; it may be MM/YYYY, DD/MM/YYYY, or YYYY/MM
If only a lot code is printed, use the manufacturer’s website or customer service to decode it
If no expiration date is shown, check the shelf life on the packaging or brand website
Use toothpaste before the printed date for best quality
Discard toothpaste if it has changed color, smell, or texture, even if the date has not passed
