Toothpaste recommendations

Choose toothpaste sweetened with xylitol; fluoride and hydroxyapatite are options for enamel support.

• Xylitol: It may help protect teeth because cavity-associated bacteria can’t produce acid from it, and it can inhibit their growth. Huberman recommends considering toothpaste that contains xylitol as a sweetener. 1 2
• Fluoride: It can strengthen tooth structure, but some people are concerned about possible thyroid or brain effects and choose to avoid it. 3
• Hydroxyapatite: Many fluoride-free toothpastes contain it; it is a naturally occurring mineral involved in enamel remineralization. 4
• Other practices: Baking soda and water can be used with a soft toothbrush, brushing gently. A high-salt rinse was also described as a swish-and-spit rinse, followed by plain water—do not swallow it. 5 6
