Teeth brushing

Does anyone else’s toddler HATE getting their teeth brushed? My daughter is 20 months and she absolutely freaks whenever I brush her teeth. To the point where her father and myself have to hold all 4 of her limbs down and she screams like she’s being killed. I try to let her do it herself too but then I always do my part and she just flips. She’s teething too so I try to be gentle but it doesn’t matter she just despises it. I’m afraid of her getting cavities because I can’t clean them well enough. Anyone else’s little one the same?? What do you do?!
