During Chaumasi Upvas (Chaturmas vrata), Jain households observe strict vows of restraint and purity. For oral care, the key is simple, non-harmful hygiene that respects the vows and the aim of purification.

What to do

• Brush teeth gently twice daily with a soft brush. If you prefer traditional methods, a neem-dant (datun) twig is acceptable and aligns with non-violence toward plants.
• If you use toothpaste, choose a mild, non-irritating variety and use small amounts to keep the practice light and mindful.
• Rinse the mouth after meals with plain water; avoid harsh chemical mouthwashes if they feel excessive during fasting periods.
• Be mindful of not harming small insects or microbes while cleaning; keep the act as a clean, non-violent routine.

Traditions differences (Digambar vs. Shwetambar)

• Both traditions encourage cleanliness and non-violence, though the exact guidelines for during Upvas can vary by family practice. The core principle remains: maintain hygiene with a gentle, mindful approach that supports the vrata.
