Answer

In Jain Dharma, during upvas, brushing teeth is generally avoided, especially with toothpaste and water, because upvas means complete restraint from food and drink, and also greater care in avoiding harm to living beings.

Many people instead do:

• Rinse carefully only if allowed by their tradition and guru’s guidance
• Clean the mouth gently without toothpaste
• Maintain silence, prayer, samayik, pratikraman, and spiritual focus

Explanation

In a strict Jain upvas, one avoids eating and drinking. Brushing usually involves water and toothpaste, and may also disturb tiny living beings. Therefore, traditionally it is not encouraged during upvas.

However, practices may vary by family, sect, health condition, and guidance of one’s guru.

Takeaway

If you are observing a strict Jain upvas, it is best not to brush with toothpaste and water. Follow the maryada taught by your guru or family tradition.
