What are the effects of the use of bactine antiseptic spray on your teeth? The whitening strips i was using started to really eat away at my enamal probably because i treated them like hair dye and left them on for as long as i possibly could. s i stopped using them and started brushing my teeth with bactine antiseptic spray after brushing with toothpaste to make sure bacteria isnt eating away at the enamal thats left and to help with staining from coffee soda ect. but now my teeth are showing signs of tooth decay and i feel its due to the bactine ive only been using it for a month 2 times a day after first brushing with regular toothpaste. what are the effects of the bactine spray used on teeth? and how can i prevent anymore tooth deacy from happening?
