For anyone curious, toothpaste has 1,000 to 1,500 ppm fluoride and tap water typically has ~1 ppm or less. Assuming OP swallowed a pea sized quantity of toothpaste (which is the reccommended amount for brushing) the amount of fluoride in that toothpaste would be about equivalent to drinking a cup of tap water.
