1. Brush your teeth at least twice a day

Brush your teeth gently in a circular motion to ensure you’re protecting your gums. Brush the inside, outside, and chewing surfaces of your teeth. Brushing with whitening toothpaste will whiten your smile,

2. Baking soda

Make a paste by mixing 1 tablespoon of baking soda with 2 tablespoons of water or toothpaste. Rinse your mouth thoroughly with water after brushing with this paste.

3. Coconut oil

Use coconut oil to rinse your mouth as it is said that it removes plaque and bacteria from the mouth, which helps to whiten teeth. Rinse your mouth with water and then drink a full glass of water. Then brush your teeth.

4. Apple cider vinegar

Make a mouthwash by mixing 2 teaspoons of apple cider vinegar with 6 ounces of water. Rinse with water and brush your teeth.

5. Lemon, orange, or banana peels.

Gently rub the fruit peels on your teeth for about 2 minutes. Make sure to thoroughly rinse out your mouth and brush your teeth afterward.

6. Use charcoal containing toothpaste

 It’s believed that charcoal can remove pigments and stains from your teeth because it’s highly absorbent. It’s said to also get rid of bacteria and toxins in the mouth.

e is required to investigate the effectiveness of activated charcoal for teeth whitening. One paper published in 2019 found that charcoal toothpaste can whiten teeth within 4 weeks of use, but it wasn’t as effective as other whitening toothpastes.

Research has found that activated charcoal can be abrasive on teeth and tooth-colored restorations, leading to loss of tooth structure. This abrasiveness may make your teeth look more yellow.

If you wear away too much enamel, more of the yellowy dentin underneath will become exposed. Be cautious when using charcoal and charcoal-based dentifrices, especially because of the lack of evidence to prove its effectiveness and safety.

7. Eating fruits and vegetables with higher water content

It’s said that eating raw fruits and vegetables with a high-water content can help to keep your teeth healthy. The water content is thought to cleanse your teeth and gums of plaque and bacteria that lead to yellow teeth.

Chewing on crunchy fruits and vegetables at the end of a meal may increase saliva production. This can help to remove food particles that are stuck in your teeth and wash away any harmful acids.

While there’s no doubt that a diet high in fruits and vegetables is good for your dental and overall health, there’s not a lot of scientific evidence that supports these claims. That said, eating these healthy foods throughout the day certainly won’t do any harm.

A review published in 2019 found that vitamin C deficiency can increase the severity of periodontitis.

While the study didn’t look at the whitening effect of vitamin C on teeth, it links high-plasma vitamin C levels to healthy teeth. The research suggests that high levels of vitamin C can reduce the amount of plaque that causes teeth to become yellow.
