Calcium supplements derived from oyster shells, dolomite, and bone meal are best avoided as they may contain lead, which can cause anemia, damage to the brain and kidneys, raise blood pressure and cause poisoning. Calculus (tartar) on your teeth may also increase while using these supplements, so visit your dentist for a cleaning whenever you feel the deposits on your lower front teeth.
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.
Good oral hygiene is a tried-and-true method for keeping your smile looking its best. Toothpastes gently buff out stains from the surface of your teeth. Whitening toothpastes work the same way with more ingredients; they don't bleach your teeth. Flossing gets rid of food and bacteria that could harden into plaque, which makes your teeth look dull and darker.
Malic acid in apples boosts saliva to wash away acids. Toothpastes with bromelain, a compound in pineapple, help whiten teeth. But there's no evidence that eating these fruits will make your grin gleam. Skip the strawberries, too. A study in Operative Dentistry found that brushing with a mixture of them and baking soda had no whitening effects. Even worse, the citric acid in strawberries can break down enamel, the outer shell of your tooth.
Tooth-whitening strips will help get rid of tooth stains. These strips are very thin, virtually invisible, and are coated with a peroxide-based whitening gel. You wear them a few minutes daily for a week or more. Results are visible in just a few days, and last at least a year. The results with strips are not as dramatic as with whitening kits, but the strips are easy to use and pretty much foolproof.
You can also try a few home remedies to whiten your teeth, though not all dentists recommend them. Brushing the teeth with baking soda can produce slightly lighter shades. You can also brush with no greater than 10% strength hydrogen peroxide. For drug store methods, gel kits are thought most effective, and brush on teeth whitener the least. However, with minimal tooth yellowing, over the counter remedies are less expensive than dental whitening, and may provide you with the lighter shade you desire.
As one dentist reporting for the Dentistry IQ website puts it, “It is a misnomer that whiter teeth are the same as healthy teeth, since tooth color has very little to do with the health of the tooth. The consumer perception, though, is that white teeth equal a healthy mouth, and perception is reality.” (1) Here’s the good news: Below I explain several home remedies that help naturally whiten your teeth, while also improving overall oral hygiene. The kind of toothpaste you use plus regular brushing and flossing, using baking soda , coconut oil pulling, and tooth-healthy diet can all whiten your teeth naturally — in addition to offering benefits like antibacterial and antiseptic protection.
