Teeth whitening at home using salt!

This is a very simple method for which you’ll just need a little salt and vinegar. Any vinegar will work, but I like apple cider vinegar because it tastes better. You could also use lemon instead of vinegar.

Step 1: Take 1 tablespoon salt and 1 tablespoon vinegar and mix them.
Step 2: Dip your toothbrush in the paste prepared in Step 1.

Step 3: Brush for about one and a half minutes.
Step 4: After this, rinse your mouth and then brush again with regular toothpaste.

Use it twice a week for best results.
