Decision
Yes - fasting-safe. Brushing your teeth does not break a fast when you spit and rinse normally.
Reason
Fasting concerns food and drink intake; oral hygiene is not a meal.
Evidence
The practical distinction is swallowing: normal brushing with spitting is not calorie intake.
How we calculate this value
Base tier: 92/100 for "Fast-safe". Item adjustment: +4 points for calories, nutrient signal, product variability, and safety caution. Final Fast Score: 96/100.
What to do
