What to Consider Before Buying
Before purchasing, I checked that the toothpaste was SLS-free and suitable for sensitive mouths. If you have specific allergies or sensitivities, reviewing the ingredient list is important. Also, availability and price were factors I considered — Rembrandt is a bit pricier than standard brands but worth it for comfort.
