Yellow teeth may seem like an inevitability of life, be it from drinking coffee, savoring red wine, or mere aging. Professional teeth whitening is an option, but there are those who would rather do it in a safe, nonchemical way at home. Good news? Some household items can remove stains and whiten the smile in the long run. (source: healthline)These are three science-backed, at-home remedies that do the job of removing yellow stains and enhancing oral appearance, without ever setting foot in a clinic or shelling out lots of money on products.

Baking soda with Hydrogen peroxide paste

This tried-and-true DIY duo is a favorite for home teeth whitening. Baking soda works as a gentle abrasive, removing surface stains, while hydrogen peroxide serves to whiten the teeth and destroy bacteria that aid in discoloration.Combine 1 teaspoon of baking soda with 2 teaspoons of hydrogen peroxide to create a smooth paste. Brush with the mixture for approximately 1–2 minutes, rinse until clean, and then use plain water. This treatment can be repeated 2–3 times weekly, but not daily, to prevent enamel loss.Why it works:The abrasive quality of baking soda mechanically removes stains, and hydrogen peroxide chemically whitens the teeth. Properly used, this paste is capable of visibly lightening the smile in a matter of weeks.

Oil Pulling with Coconut oil

Oil pulling is an old Ayurvedic technique that involves swishing oil around the mouth to clean it of bacteria and toxins. Coconut oil is commonly used for its good taste and antimicrobial effect.Swish around the mouth for 10–15 minutes with 1 tablespoon of coconut oil prior to brushing. Avoid swallowing the oil since it is full of bacteria and toxins at this point. Rinse with water and brush teeth as normal. This method is to be employed daily or a few times a week.Why it works:Oil pulling decreases the formation of plaque and bacterial growth, both of which can lead to yellow staining. Regular oil pulling over time can cause a visibly cleaner, whiter smile.

Apple cider vinegar rinse

Apple cider vinegar (ACV) is a natural antibacterial and whitening agent, but it is highly acidic and should thus be used with great care.Mix 1 part apple cider vinegar with 2 parts water. Rinse in the mouth for 30 seconds and follow up with a good rinse using water. Use the rinse no more than once or twice per week, as too frequent use can damage the enamel.Why it works:The organic acids present in a cup of ACV break down stains and destroy bacteria. If applied in moderation and properly, it can make teeth look whiter and improve overall oral health.
