Is that an expiration date or a lot code?

A lot code identifies a batch and may not be a date. Keep it exactly as printed when asking about your tube.

How should I store it?

Follow the packaging instructions, close the cap after use and keep the opening clean. Store toothpaste out of reach of young children and pets.

What if it looks or smells different?

Contact the brand if the seal, smell, texture or appearance concerns you. For Tooth Wizard, include the flavor, lot code and a photo with your question.
