saves our toothbrushes [SEP] my daughters enjoy munching on their toothbrushes which would make it to we were going through toothbrushes very quickly trying to stop them was frustrating and caused unnecessary battles we purchased these for them to chew on and rub on their gums after tooth brushing it has stopped the problem for us and their current toothbrushes and not being chewed to frills the reason i give this stars is because on my year olds nuk the bumps are coming off from the chewing if it was used any more aggressively i don t know how it d hold up nevertheless we ll buy another for our next child s teething needs
