Help on getting my 9mo to sleep in her crib

My 9 month old will not sleep in her crib anymore. She’ll fall asleep in bed with me and my bf then when she falls asleep we put her in her crib. Like 20 minutes to an hour later, she’ll start crying and won’t go back to bed until we put her in our bed. I believe it’s because she’s teething. She never used to do this. She would sleep 12 hours a night in her crib before. I can’t do the cry it out method b cause it breaks my heart and I’ll cave in. What should I do. I need help 😭😭😭
