Baking soda and lemon bad for teeth?

1 doctor agrees

In brief: Together, yes

Citric acid breaks down tooth enamel, and baking soda is abrasive.
Terrible combination. You'll be doing more harm than good. If you are trying to whiten them, then you'll need to use professional grade products designed to whiten teeth without harming them. Speak to your dentist.
