Mint flavor in toothpaste can disrupt sleep, because it acts as a stimulant that keeps you alert and improves your memory and responsiveness.

According to's Chris Winter, a dentist, peppermint "can have adverse effects on your sleep, as it is known to increase dopamine."

When dopamine is released in the brain, it promotes alertness and alertness, the exact opposite of your intention before bed, which disrupts a peaceful routine.

Since the mint flavors in toothpaste stimulate the brain, you may find it difficult to sleep, especially if you brushed your teeth right before bed.

Peppermint works in an almost similar way to blue light, which is high-energy visible light emitted by cell phones and televisions.

Many experts recommend avoiding using your phone before bed, because the blue light from your device easily passes through your eyes to signal the brain that it's time to wake up.

The strong flavor and scent of mint toothpaste does something similar, so if you're finding it difficult to sleep, it may be time to switch up your toothpaste.

What is the solution?

To avoid disrupting your sleep, experts suggest brushing your teeth an hour or so before going to bed, to allow the strong mint flavor to dissipate so it doesn't keep you awake.

The second solution is to replace the mint paste with another flavor that is more comforting and soothing, such as ginger, cinnamon, or lavender.

Other factors for better sleep

Experts say you should get about seven to eight hours of sleep every night.

People looking to improve their sleep can take the following steps:

  • Keep the bedroom cool, dark, and quiet.

  • Maintain a consistent sleep and wake schedule.

  • Exercise regularly.

  • Avoid stimulants, such as caffeine, in the afternoon.

Medications may also be prescribed to treat insomnia and a CPAP (continuous positive airway pressure) machine may be used by people with sleep apnea.
