Can I use a whitening pen

I know some teeth whitner things you cant use but some you can if the peroxide is small or its not a rinse and its a tooth paste etc.
I know most tooth pastes have them now my current one does and I used it with my son and never knew then...
this pens first ingredient is water then peroxide ....also it has hydrogenated castor oil?
...I know usually the deal is not large amounts of either ingredient so is that a no go or because its in a pen not even a gel or mold the amount is so minute its ok?


for peroxide whats the bad side effects of it in pregnancy anyway if someone knows
obviously dont drink peroxide lol but what can it do to a unborn child since its in most oral hygene products

You canuse baking soda and hydrogen peroxide to brush you teeth to help whiten it. Thats what ido.. Inever heard anything aboutnot using nydrogen peroxide pregnant. I didnt know :/

that eats my enamel this pen since it has the castor oil and its very diluted will help gradually whiten it enough that it wont bleach my gums and make my teeth super sensative from eating my enamel ...I am super picky about health things like this my family is big on beauty stuff and lets just say not all of them went the healthy way about it and some of them look like orange husks with wispy straw white hair and eaten up fake teeth with infected contacts etc. I could go on...
