If you'd like to improve your teeth's color or simply desire a better and brighter smile, there are many options for whitening teeth. Going to a professional can be costly and some home kits are accessible, but might not bring the desired results. Fortunately, there is one method that doesn't involve the use of chemicals, it's cost-effctive and available anywhere. Just save that banana peel from your lunch!

Teeth whitening is a popular dental procedure, but because this is not a one-time process, according to the Colgate Oral Care Center, you will have to budget spending for it. Whitening kits are available for $3 to $60 at Walmart, but because these contain bleaching chemicals, the use of a kit could lead to dental health problems like tooth sensitivity, gum irritation and unevenness of the teeth's color, according to Prevention. Professional services averagely cost $400 per treatment and will depend on the dentist's skills and tools, according to Real Self.

Don't throw away that banana peel! You can use it to whiten your teeth without any cost or chemicals

If you're not ready to shell out some cash or don't want to run the risk of weakening your teeth, you can get sparkly whites with items you already have in the house - a banana peel, a toothbrush and toothpaste.

Here's how you can whiten your teeth with banana peel:

1. Rub the fleshy side of the banana peel against your teeth. You will start feeling your gums getting pasty, but be patient for at least 10 minutes and try not to rub your lips or the gums against the texture. Read, watch the news or surf the internet as you wait.

2. After 10 minutes, grab your toothbrush - make sure it is dry - and start brushing your teeth in circular motions. Rinse with water.

3. Brush your teeth with regular toothpaste to finish the process.

Do this daily for two weeks or until you get the desired results.

Bananas contain potassium, magnesium, manganese and acid that can help break down dirt and stains on teeth. The grittiness of its fiber also helps polish tooth enamel. However - full disclosure - there is no scientific evidence to back up the effectiveness of banana peels for tooth whitening.
