Answer

In Jain practice, during upvas, many people avoid brushing with toothpaste because it may involve taste, swallowing, or use of substances.

However, basic mouth cleaning may be done carefully according to one’s family, guru, or sangh tradition.

Explanation

During upvas, the aim is to reduce attachment to the body and senses. Brushing with toothpaste can be avoided because:

• Toothpaste has taste.
• There is a risk of swallowing water or paste.
• It may involve unnecessary bodily comfort.

Many Jains instead rinse the mouth carefully with boiled and cooled water, without swallowing. Some may avoid even that depending on the strictness of the upvas.

Spiritual Understanding

Upvas is not only about avoiding food; it is a practice of self-control, awareness, and detachment. The more carefully it is observed, the deeper its spiritual value becomes.

Takeaway

If you are doing a strict Jain upvas, it is best to avoid brushing with toothpaste. Follow the guidance of your guru, elders, or local Jain tradition.
