You cannot ignore dental hygiene as laxity may cause oral diseases, and discolored teeth may also affect your overall personality and presentation. The minimum requirement to keep your teeth clean and healthy is to brush them twice a day with fluoride toothpaste and a good brush. However, the teeth also get discolored with the consumption of food and drinks that lead to stains, tobacco use, certain medicines, and diseases. Advancing age and injury to teeth may also cause discoloration of the teeth. Apart from these causes, too much fluoride in water or toothpaste also results in tooth discoloration, and family history is also a cause of dental health issues.

Several teeth whitening products are available in the market, and Americans spend billions of dollars on these products. However, exposure to chemical components present in some of the main teeth whitening products available may cause enamel erosion. On the other hand, some natural products are chemical-free home remedies to keep the teeth white:

• Oil pulling
  Oil pulling is an ayurvedic therapy that originated in India many centuries ago. It has many proven benefits and cures, including killing bacteria, treating tooth decay, and preventing bad breath. It also heals bleeding gums and prevents cavities.
  Though there is a lack of scientific evidence to back oil pulling as an effective way to ensure teeth whitening, there are numerous testimonials online to suggest this method. People who have tried oil pulling swear by its benefits, especially as a teeth whitener.
  Bacteria in the mouth cause plaque, which discolors the teeth. The process of oil pulling rinses the mouth with oil so that the oil is pulled through the teeth and the mouth. It kills the bacteria and reduces plaque, leaving the teeth clean and white.
  Coconut oil is the main teeth whitening product used for oil pulling. Just pour a tablespoon of oil into the mouth, swirl around for up to 20 minutes, and spit out the oil in the end.
• Baking soda
  Baking soda has natural bleaching properties and is present in many kinds of toothpaste. The abrasive quality of baking soda removes stains on the teeth, leaving them clean and white. The alkaline property of baking soda, on the other hand, kills bacteria in the mouth and prevents the growth of plaque.
  Since it is a natural product, teeth whitening results may not be dramatic. Various studies show that toothpaste containing baking soda gives better results over time than a type of toothpaste without this ingredient.
  Simply make a paste of baking soda with water and brush your teeth a few times a week for better results.
• Apple cider vinegar
  People have been using apple cider vinegar as a cleaning agent for its bleaching properties. The acetic and abrasive nature of the vinegar kills bacteria and removes teeth stains.
  However, this product should be used with care as it softens the teeth when it comes in contact with them for long. This is one of the main teeth whitening products, but it is also advised that it should be used only a few times a week.
  Dilute apple cider vinegar in water and use it as a mouthwash.
