That’ll be a risk if you have pure sodium fluoride sitting around. Fortunately “no one” does. (Yes, industrial toothpaste manufacturing workers might have an opportunity to be exposed to such a thing).
Typical toothpaste is 1000-1100 ppm of sodium fluoride. “Prescription strength” is about 5000 ppm. So to hit your target LD50 you need to eat around 10 g of toothpaste per kg. Assuming on the extremely small end (40 kg bodyweight): if I did my math right, that’s about 400 g of prescription strength toothpaste, or more than two (170 g) tubes.
Normal toothpaste (1100 ppm) for a normal person (80 kg female average), you need to eat more than 22 tubes of toothpaste to kill half the people involved.
Thats just stupid, there’s zero risk of any of that happening.
Look, I’m not saying the average consumer will ever run into this risk, I’m saying that you shouldn’t go around saying H301 acutely toxic chemicals are as safe to ingest as bananas. You’re not the president of the United States.
