Teeth Whitening: 7 Ways To Naturally Remove Tooth Discolouration and Stains With Simple Home Remedies

If you want whiter teeth, but also want to avoid the chemicals, then here we’ll show you many teeth whitening options that are both natural and safe. Unfortunately, most mainstream teeth whitening products contain peroxides and other harsh chemicals that can actually, eventually, lead to damage on both teeth and gums.

There are multiple factors that cause teeth to become dull and lose their bright, white sparkle. Here are seven natural remedies for whiter teeth that you may already have in your kitchen!

What Causes Teeth Discolouration?

There are distinct factors that lead to discolouration. Ruling them out early can keep your teeth healthier and whiter for longer. 

Enamel Thinning

The outer layer of teeth consists of enamel, which is coloured almost white and protects the deeper tooth structure. However, when this outer layer thins, it reveals the natural yellow colour of the core tissue of your teeth, making your teeth appear discoloured. 


Teeth become discoloured due to stains that develop on the enamel as well as inside the tooth itself. Underneath the enamel is a pale brown substance called dentin, which can become more visible when the enamel gets thinner. Unlike dentin that becomes discoloured from age and trauma, the enamel is often stained from the foods and drinks we consume.

Many dark-coloured foods and drinks contain chemicals called chromogens, like the tannic acid in red wine, and this chemical is what can stain tooth enamel. Furthermore, this can cause discolouration and tooth stains.

Poor Diet

Not having adequate nutrition can also be the cause of premature tooth ageing, as all parts of the body. 

A lack of vitamins and nutrients can make your teeth age quicker, making them appear more yellow. It should be noted, that eating foods like nuts, raw carrots, apples, and cauliflower can help keep your teeth clean by removing surface stains and plaque that leads to cavities. So be sure to eat better to see an improvement in your teeth!

Sugary Drinks 

Cutting down on your sugar intake helps to promote strong, healthy teeth and avoid dental damage.

Sugars feed the bacteria which naturally live around your teeth and this can cause them to multiply rapidly, which eventually leads to staining. So, try and switch to unsweetened alternatives to sugary beverages.

Ageing can cause discolouration even if your dental hygiene routine has been perfect. As you age, the outer layer of the tooth’s enamel slowly gets thinner over time. This leads to the reveal of the natural yellow colour, which is found in the core tissue of your teeth. Thus, the natural process can lead to yellowish-brown spots or large patches or discolouration.

Also, the damage, injuries or staining to your teeth, which occur over time throughout your life, cause discolouration that can become noticeable with age.

This is probably the worst cause of tooth decay and discolouration. Not only can smoking frequently stain your teeth, but it can also damage some teeth beyond repair after a long period. This is typically due to the tar and tobacco found in nicotine. In addition to this, tobacco can interfere with saliva production which helps the surface of your teeth keep clean. 

Eliminating tobacco from your lifestyle can help keep your teeth healthy and bright.

Tooth colour varies from person to person and may even be genetic.  Where some people naturally have very white teeth, others can have slightly yellow or even beige teeth.  Furthermore, there are also certain genetic disorders that cause brown spots on teeth.

How to Prevent Your Teeth from Becoming Stained

It’s important to know how to prevent tooth discolouration after teeth whitening, so your teeth stay looking pearly white for a long time.

Limit Staining Foods and Beverages

Certain foods can stain your enamel, which is the outermost layer of your teeth. Foods and beverages that contain tannins, such as wine and tea, can stain the teeth. 

Over time these beverages stain the teeth on the surface. These kinds of stains can enter cracks and crevices present on the enamel of the tooth. If possible, you should avoid drinking beverages which are known to stain teeth. If, however, it cannot be avoided then you should use a straw, as this will prevent direct and prolonged contact of the liquid with your teeth.

Tip: Brush your teeth soon after consuming foods or drinks to limit the amount they stain your teeth. But, make sure you wait thirty minutes after eating before brushing to protect the enamel – immediate brushing can spread the abrasive liquid and further damage your teeth.

Chew Sugarless Gum

Chewing gum is also very beneficial when it comes to maintaining a white smile. Also, chewing sugarless gum can help neutralise the acids found in the mouth. Chewing increases saliva flow, which helps rinse your teeth as well as increasing your saliva’s ability to neutralise acid and remineralise your enamel, ultimately strengthening teeth.

Why are natural remedies better for whitening teeth?

Some mainstream teeth-whitening products rely on chemicals, including bleach and acidic methods, to strip your teeth. Whilst seemingly beneficial, on the other hand, this can sometimes cause long-term damage to your tooth enamel. More so, the constant application of whitening strips has been shown to cause erosion of enamel over time and also promote tooth sensitivity.

We thoroughly recommend the use of natural home remedies, as these can be much gentler to your teeth. Importantly, they can also scrub away any stains or discolouration on your teeth. 

So, keep reading as we reveal our top home remedies to naturally whiten your teeth.

Home Remedies to Naturally Whiten your Teeth

Brush Your Teeth with Baking Soda

Baking soda has natural whitening properties, which is why it’s a popular ingredient in commercial toothpaste. It’s a mild abrasive that can help scrub away surface stains on teeth.

To use it to whiten your teeth, create a thin paste by mixing a teaspoon of baking soda with a small amount of toothpaste and water in a small dish. Then, use a soft toothbrush to apply to teeth and gently brush your teeth in circular motions for two minutes. 

The crystals will buff away stains while also neutralising and counteracting any bacterial acid in your mouth. However, be aware that, over time, baking soda can wear down the protective enamel on your teeth. So, it is not a good idea to use this treatment every day. 

Stick to using it once or twice a week for whitening results without the risk of damage.

Coconut Oil Pulling

Oil pulling is an ancient Indian technique that removes plaque and bacteria resulting in whiter, brighter teeth.

Coconut oil contains fatty acids that are broken down into teeth whitening enzymes when they come in contact with human saliva. Simply, using coconut oil acts as a way to protect your teeth and gums. Whilst the oil also has antimicrobial properties, so it’s great for protecting and cleaning your gums as well, it is also safe to do daily.

Thankfully, unlike ingredients that could pose a risk to your enamel, coconut oil isn’t at all abrasive. It is also great for reducing the likelihood of bad breath, along with reducing your chances of developing gum disease.

To use this tooth whitening technique, place a teaspoon of coconut oil in your mouth. Wait for it to become liquefied, which should not take too long. Then, swish it for fifteen to twenty minutes until you cover all your teeth. Next, spit out the oil and rinse your mouth with warm water before brushing and flossing. Alternatively, you can mix coconut oil with your usual toothpaste and brush your teeth like normal.

Tip: If can’t use coconut oil, sunflower oil or sesame oil will work just as well.

Make a Strawberry Paste

Strawberries contain malic acid in addition to vitamin C, as well as this, it can act as a natural astringent for your teeth to remove stains and plaque. It is most effective when the fruit is “just ripe” as malic acid declines as fruits ripen.  

To get the full effect from strawberries, it’s recommended that you mash up the strawberries and brush your teeth with the paste. However, make sure that you thoroughly rinse off the berries since they do contain natural sugar!

Use Apple Cider Vinegar

Since it’s naturally acidic, apple cider vinegar helps to break down plaque and other substances stuck to the teeth. This is due to the pH of apple cider vinegar, which can remove stains from your teeth, helping to naturally whiten your teeth.

To use it as a mouthwash, dilute it with water and swish it around in your mouth for several minutes.  Be sure to rinse your mouth with plain water afterwards. For repeat use, rinse your mouth with this solution every morning before brushing your teeth to help to remove stains, freshen breath and kill the bacteria around your gums.

Banana Peel Rub

You can use the inside of a banana peel, which is rich in potassium, magnesium, manganese, and other minerals, to whiten teeth. The rich minerals found in bananas, which have healthy whitening effects, are absorbed into your enamel. 

Simply, rub a small piece of the inside of the banana peel off your teeth for two minutes. Then, rinse with water. It’s important to brush your teeth afterwards to remove any banana residue. Also, since they do not have the abrasiveness that other natural whiteners have, you can use banana more frequently without worrying about it wearing out your enamel.

Use Turmeric Powder

You may not expect turmeric to work since it is often associated with yellowing of the skin, but it actually does the opposite. The use of turmeric as a natural teeth whitener is popular due to it being anti-inflammatory and anti-microbial. It also contains antioxidants.

Working as a gentle abrasive, it can remove surface stains to reveal whiter teeth. Simply, create a thin paste by mixing a teaspoon of turmeric powder and a small amount of water in a small dish. Then using a soft toothbrush, apply the paste to teeth and gently brush for two minutes. Don’t forget to brush your teeth with regular toothpaste afterwards!

Activated Charcoal Mask

Though it may seem counterintuitive to blacken your teeth with charcoal to whiten them, this trick actually works. As activated charcoal is highly absorbent it is able to effectively bond with surface stains, and then lift them away.

Activated charcoal is different from regular charcoal because it has been processed with heat and oxygen or chemicals which helps to increase its capacity to absorb impurities. It is thoroughly recommended that you make sure you use medical grade activated charcoal or charcoal that has been specifically designed to whiten teeth.

Make the paste by mixing together a half a tablespoon of activated charcoal with a little water to make it into a paste-like consistency.

Then apply the mask to your teeth, let it sit for three minutes, and then rinse it away.

How to use home remedies safely

Don’t Overdo It

Naturally whitening your teeth at home is safe, and effective, if done correctly. We strongly advise that you use these natural tooth whitening remedies occasionally to avoid damage to the tooth enamel.

How to maintain good oral hygiene to keep your teeth healthy

Maintaining excellent oral hygiene is the most important thing that a person can do to reduce their teeth yellowing.

Brush Your Teeth Twice a Day

Good oral hygiene is a tried-and-true method for keeping your smile looking its best. More so, regular brushing can protect the enamel, prevents gum decay, and remove stains.

So, try and brush your teeth in the morning and again before bed, for two minutes, with a soft-bristled brush to keep them clean and as healthy as possible. Professionals recommend you ensure your brush has soft/medium bristles so that they won’t don’t damage your gums. Furthermore, it is recommended that you choose a toothpaste with fluoride. Fluoride will help prevent tooth decay by strengthening your tooth enamel and fighting away bacteria that cause cavities.

Or choose a whitening toothpaste which helps to remove surface stains that cause yellowing and help you to achieve a brighter tooth surface.

Floss Your Teeth

Flossing is one of the most important steps in your dental care routine, besides brushing. This is because it helps you get to places you simply can’t reach with a toothbrush, leading to healthier teeth and gums.

Plaque and food particles between your teeth can make your smile look dim overall. So, by flossing you can easily remove the staining between your teeth, helping them to look whiter. Thus, flossing regularly will not only improve the health of your gums, but you will also notice your smile looking brighter.

Use Mouthwash after Brushing

Mouthwash gets into the gaps cleaned out by brushing and flossing. However, do avoid using mouthwashes that are chlorhexidine-based, unless advised by your dentist. This is because they can actually cause a lot of stains on your teeth if used for prolonged periods of time.

Replace Your Toothbrush Frequently

Over time, the bristles of your toothbrush begin to wear out and become soft. Once the bristles look tired, that means your brush isn’t cleaning your teeth properly. Furthermore, when this happens, a brush no longer removes plaque and debris from teeth effectively enough to maintain optimum dental hygiene. 

If you want a whiter smile, you should replace your trusty toothbrush at least once every three months to be sure it’s getting the job done.

Clean Your Tongue

Brushing your tongue isn’t only about having fresh breath. In fact, bacteria can accumulate on your tongue which can lead to your teeth being stained. Furthermore, brushing your tongue with a toothbrush does not remove the bacteria, but rather just moves it around the mouth. This is why we recommend using a tongue cleaner, as this is the most effective way to kill the bacteria that is the cause of plaque and gum disease.

Visit Your Dentist Regularly

While you can do lots to keep your teeth healthy and clean, it is wise to consult an expert from time to time. Regular cleanings from a dentist will help you keep your oral health in check and alert you to any potential issues sooner, rather than later.

So, going to the dentist regularly can make a difference beyond just the health of your teeth and mouth. Your dentist should also be able to recommend safe, effective products that will not irritate your mouth.

So, try and visit your dentist every six months.

Drink Plenty of Water

Water is not only essential for overall wellbeing, but it is also vital for great oral health. Drinking water throughout the day promotes saliva production, which in turn helps keep your teeth healthy and white.

Sipping water during and after a meal also helps rinse your mouth of any debris and loose plaque. In fact, this keeps any residue from building up.

It’s important when consuming any pigmented food or drink to consume plenty of water as drinking water neutralizes the pH of the oral cavity and helps to clear the food or drink out of the mouth.
