New favorite or helping her lost?

Recently I got my 2.5 year old off her pacifier which she was OBSESSED with but only used it at night or naps. (Dentist high recommend no more pacy)

But now she’s obsessed with her toothbrush. Is she just using it as a “back up” for a pacifier or could it be her new thing?

Just curious as to if I should take that away too (it’s not the one she brushes her teeth with, we have a pack of them and it’s just one out of the pack).

She don’t keep it in her mouth she legit just brushes her teeth and her baby dolls teeth lol
