I never got sealants but did get fluoride treatment and brushing twice a day as a kid. I never had a cavity either and even as an adult I can maybe count the number of cavities I had on one hand. (And I brushed my teeth maybe once a day, don't judge me.) Honestly my diet played a huge role here, but the sealants, fluoride, and twice daily brushing just give you so much more protection than you could expect from brushing alone.
