Answer

In Jain practice, it is generally better to brush before taking Navkarsi Pachchakkhan.

After you take Navkarsi Pachchakkhan, you should avoid putting anything in the mouth until the Navkarsi time is completed. So brushing after Pachchakkhan is not appropriate.

Simple Order

• Wake up
• Brush / clean mouth
• Do morning spiritual practices as per your routine
• Take Navkarsi Pachchakkhan
• After Navkarsi time is over, eat or drink as allowed

Explanation

Navkarsi means taking a vow not to eat or drink until after a certain time after sunrise. Once the Pachchakkhan is taken, one should maintain the vow carefully.

Brushing usually involves water and movement in the mouth, so it should be done before the Pachchakkhan.

Takeaway

Brush first, then take Navkarsi Pachchakkhan. Eat or drink only after the Navkarsi period is complete.
