““Clean and Healthy Teeth Apple cider vinegar is also known to clean and remove stains from your teeth. Before you try to use bleach to whiten your teeth, first try apple cider vinegar. You can apply some apple cider vinegar directly to your toothbrush and brush the stains. Rinse and you should have nice white teeth. Apple cider vinegar will also break down plaque and fight bacteria in your gums and teeth.””
