Does using toothpast with baking soda make my teeth whiter than toothpaste without baking soda? What's the Independent variable and what's the dependent variable, and also constant.

Teeth whitening is the dependent variable.

Toothpaste with or without baking soda are the independent variables.

Explanation:

An independent variable is required to be altered and tested on the experimental or dependent variable to know the effect of the independent variable on the dependent variable.

Here, the teeth whitening is the dependent variable which depends on the type of material used for making them white. The tooth paste with or without the baking soda is tested on teeth to check their whitening.
