Tips To Manage Modafinil Teeth Grinding

  • Reducing the dosage of Modafinil can help prevent teeth grinding associated with its use and decrease the overall stimulant effects on the body.
  • Using a mouthguard can help protect your teeth and jaw from the effects of teeth grinding.
  • Chewing gum can also help in preventing Modafinil teeth-grinding in the following ways:

Firstly, it provides a distraction from the urge to grind or clench your teeth.

Secondly, it increases saliva production, which helps lubricate the mouth and reduces the risk of tooth damage.

Thirdly, it engages the jaw muscles, helps relieve tension, and reduces the urge to grind or clench.

However, it is necessary to choose a sugar-free gum to avoid dental problems linked with sugar consumption.

  • Avoid taking caffeine or stimulants. Limiting or avoiding these substances helps in reducing the occurrence of teeth grinding.
