Sayed Ibrahim, PhD, chief executive officer of SprinJene, which makes natural oral health products, suggests giving new toothpastes two-week trials so you can observe how they affect your oral health. “Don’t just go for the flavor or taste,” he advises, noting that some natural toothpastes can feel or taste different than conventional varieties. 

If you’re missing the taste of your traditional toothpaste, you could always use a drop of peppermint essential oil to your toothbrush. That way, you get that minty flavor without the artificial sweeteners.
