How to Improve Oral Health & It's Critical Role in Brain & Body Health

Brushing & Flossing

Proper brushing and flossing are essential for maintaining oral health and preventing gum disease. Andrew Huberman emphasizes using a soft toothbrush and a gentle circular motion to protect the gums and teeth. He also highlights the importance of correct flossing techniques, such as gliding the floss along the side of the tooth and using a water pick for those with tightly spaced teeth 1.

Every single one of them said that very vigorous brushing with medium or hard bristles disrupts the interface between the teeth and gums.

For children, Huberman advises focusing on brushing rather than flossing if there are large spaces between their teeth 2.

   

Mouthwash & Tongue

Mouthwash and tongue care play significant roles in oral hygiene. Huberman warns against alcohol-based mouthwashes, which can harm the oral microbiome and reduce nitric oxide production, crucial for vascular health 3. Instead, he suggests opting for non-alcoholic alternatives to maintain a healthy oral environment.

Alcohol-based mouthwashes are known to reduce the amount of nitric oxide that's produced in the oral cavity.

Additionally, he recommends brushing the tongue with a separate toothbrush to prevent bacterial crossover and maintain fresh breath 4.

   

Hygiene Timing

The timing of oral hygiene routines is crucial for optimal dental health. Huberman stresses the importance of nighttime brushing and flossing, as saliva production decreases during sleep, leaving teeth vulnerable to bacterial attack 5. He advises brushing and flossing at least twice a day, with nighttime being the most critical time.

If you're going to brush and floss just once per 24 hours, the critical time is at night before you go to sleep.

This routine helps maintain the oral environment and prevents tooth decay, ensuring long-term oral health 6.
