Here at Treehugger, we’re fans of toothpaste tabs because they’re generally more eco-friendly than paste. It’s easy to find tabs in plastic-free, fully recyclable packaging. Some local shops even offer totally package-free refills. Because tablets are an individual portion, you won't accidentally use too much per cleaning. Another benefit is that they’re lightweight and ideal for travel. The TSA’s liquid and gel limits don’t apply to them, and they won’t leave a pasty mess inside your luggage if they leak.
