10 month old is waking up once a night

so i know this is a sleep regression and he has a tooth coming in. BUT he literally wakes up in the middle of the night about 3-4 times a week and won’t go back to sleep for about an hour. i keep caving in and rocking him for a little bit before i put him back in his crib, but he cries even harder when i do that. i’ve tried just rubbing his back to calm him and that doesn’t work. he literally will just freak out worse if he sees or hears me. i feel like my only option is to let him cry it out but i don’t know? i’m a little lost on this one. i don’t feel like he’s hungry because he had an 8oz bottle at 9pm and it’s now 5am (he woke up at 430). up until a couple weeks ago he was sleeping from 830pm-7am.
