Rinse your mouth with water. Rinsing with water after meals or drinking caffeinated beverages will help remove any leftover food or residue from your teeth will help prevent stain and decay.  This method is especially useful if you’re away from home and don’t get a chance to brush or floss after eating. Drinking water throughout the day and rinsing with clean water after meals is the most underrated method of overall oral health.
Chew a piece of gum. Studies show that chewing sugar-free gum that contains xylitol for 20 minutes a day following meals can help prevent tooth decay. Chewing gum increases saliva production which in turn washes away food debris, neutralizes acids produced by bacteria, strengthens tooth enamel, and provides disease-fighting substances throughout the mouth.
Get more exposure to sunlight. Your body naturally makes vitamin D when exposed to sunlight. People with light skin should try to get at least 10 to 15 minutes of sunlight, while people with dark skin should get at least 30 minutes of sunlight exposure daily. Clouds, smog, clothing, sunscreen and window glass all reduce the amount of sunlight that actually reaches the skin.
What’s the secret of ACV? It contains compounds, including acetic acid, potassium, magnesium, probiotics and enzymes, which kill germs (dangerous “bad” bacteria) and at the same time foster the growth of beneficial “good” probiotic bacteria. Since it’s naturally acidic, it helps break down plaque or other substances stuck to the teeth. The pH of apple cider vinegar can remove stains from your teeth, which helps naturally whiten your teeth.
Make a paste of baking soda and lemon juice. It will likely fizz and foam a bit. Wait for it to settle down and use this solution to brush your teeth. Rinse well. You don’t need to follow with your regular toothpaste, but you can if you wish. Lemon juice contains citric acid, so it can damage your teeth if used too often. Only do this once a week for best results.
I think that using baking soda is a time honored classic. I have heard all growing up that it would be a good alternative to toothpaste and could help keep them whiter. So, I do brush with it every now and then, I just hate the taste. I will have to try some of your other suggestions though. The most intriguing being the use of clay powder. Thanks.
Given all the mixed press on hydrogen peroxide, it may be helpful to know that the human body produces hydrogen peroxide primarily in the lungs, gut and thyroid gland. A fascinating study done in 2009 at Harvard University suggests that the presence of hydrogen peroxide actually ‘calls’ the immune system to an injury. (3) This makes sense when you consider that hydrogen peroxide is such a biologically fundamental ‘defense’ strategy at a cellular level.
