It may be best to choose a few treatments and rotate them throughout the week. Some of the suggestions below do not have research to support them, but have been proven to be effective by anecdotal reports. But here’s our list of the top 5 ways.
1. Brushing your teeth
Your first plan of action should be to brush your teeth more often and in the correct manner. It’s especially important that you brush after consuming foods and drinks that can lead to yellow teeth.
However, be careful with brushing immediately after consuming acidic foods and drinks. Brushing right away can make the acids brush away more enamel and lead to erosion.
Brush your teeth at least twice a day for 2 minutes at a time. Make sure you get into all of the cracks and crevices. 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. Using an electric toothbrush is also more effective in removing surface stains.
Brushing with a whitening toothpaste has also been scientifically shown to whiten your smile. These whitening toothpastes contain mild abrasives that scrub the teeth to remove surface stain, but are gentle enough to be safe.
2. Coconut oil pulling
Coconut oil pulling is said to remove plaque and bacteria from the mouth, which helps to whiten teeth. Always shop for a high quality, organic oil, that doesn’t contain harmful ingredients.
Swish 1 to 2 teaspoons of liquid coconut oil in your mouth for 10 to 30 minutes. Don’t let the oil touch the back of your throat. Don’t swallow the oil as it contains toxins and bacteria from your mouth.
Spit it into the toilet or a wastepaper basket, as it could clog drains. Rinse your mouth with water and then drink a full glass of water. Then brush your teeth.
Study found that oil pulling using sesame oil and sunflower oil reduced gingivitis caused by plaque. Oil pulling could have a whitening effect on teeth, as plaque buildup can cause teeth to turn yellow.
3. Teeth Whitening Spray
This is the most reliable and proven way. This is an effective way of lighting the natural shade of your teeth. Don’t forget that teeth whitening can’t completely change the colour of your teeth, but it can lighten the current shade of your teeth—making you smile brighter. Whitening can whiten your teeth an average of 6-8 shades lighter.
4. Apple cider vinegar
Apple cider vinegar can be used in very small amounts to whiten teeth. Research published in 2014 Trusted Source found that apple vinegar has a bleaching effect on cow teeth. So here you have it – if it works on cows, it might work on yours!
Make a mouthwash by mixing 2 teaspoons of apple cider vinegar with 6 ounces of water. Swish the solution for 30 seconds. Then rinse with water and brush your teeth.
However, it should be noted that it has the potential to cause damage to the hardness and surface structure of teeth. So, use it with caution, and only use it for short amounts of time. More human studies are needed to expand upon these findings.
5. Activated charcoal
You can use activated charcoal to remove stains from your teeth. 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. There are toothpastes that contain activated charcoal and claim to whiten teeth.
If your teeth are sensitive or you want to limit the abrasiveness of the charcoal, you can dab it on your teeth. Leave it on for 2 minutes.
More scientific evidence 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.
Please be careful with at-home whitening, though, because you may damage your teeth if products are used incorrectly or for too much time. Be cautious because you can damage your enamel or gums, which can lead to sensitivity and cavities. The best way to whiten your teeth is to prevent stains before they happen, continue to practice good oral hygiene.
If you’ve tried these methods without success, your dentist may be able to help you determine if another treatment method may be a better option. Experiment and find the way that works for you!
