How many nights in a row can I give Motrin?

My 8.5 month old has been teething for almost two weeks now. He’s cut 2 new teeth already and another is cutting now 😭 How many nights in a row is it ok to give Motrin? I never give it during the day, just once at night right before bed.

When he cut his first two teeth at 7 months it didn’t feel as bad 😩 poor baby. Are top teeth usually worse than bottom teeth? That’s how it seems.
