Can I Use Whitening Strips Hile Nursing What Can I Use To Whiten My Teeth Without A Dentist Or Whitening Strips?

What can I use to whiten my teeth without a dentist or whitening strips? - can i use whitening strips hile nursing

I brush and floss every day, but my teeth are still yellowish. I can not afford to bleach the teeth by a dentist and do not want to use whitening strips because they do not help themselves. I need suggestions on what may be in place and how to use it. Thank you!
