Common Causes Of Tooth Discolouration

The Most Common Causes Of Tooth Discolouration

It is easy to get tooth discoloration with the diet and lifestyle of today. Yellow or discoloured teeth are not liked by anyone. The darkening of otherwise white teeth can be caused by consuming too many stain-causing beverages and foods. Smoking and drinking too much red wine, tea or coffee can also have the same effect. Our choice of foods and drinks can have a significant impact on the colour of our pearlies. However, there are other factors that also contribute to this. Once your teeth are stained and yellow, there are many options to restore them back to being nice and what. Veneers are a great option but the in chair teeth whitening also restores your smile. Let’s look at the most common causes of tooth discolouration.

Tobacco/Chromogenic Foods/ Drinks

The consumption of tobacco and foods and beverages containing chromogenic dyes are major contributors. Red wine, coffee and cola drinks are examples. Smoking tobacco products can have a cumulative impact, so the degree of yellowing depends on the amount of smoke you consume.

Smoking tobacco products can have a cumulative impact, so the degree of discoloration of your teeth is largely dependent on how much you smoke.

Poor oral hygieneCommon Causes Of Tooth Discolouration

It is often recommended that we brush our teeth in order to remove food particles and plaque stuck between teeth and gums. It is important to stress that brushing and flossing regularly will help reduce the chances of staining. Brushing immediately after drinking stain causing beverages can reduce the chance that the stain causing substances will adhere to the tooth enamel for long enough to cause cumulative staining. Regular professional cleaning by a dentist or hygienist will not only remove yellow plaque but also staining.


While certain antibiotics such as Tetracycline and Amoxicillin are safe to use in pregnant women, they can stain the teeth of an unborn child. Children who use these medications frequently can also develop deep stains. Ironically, mouthwashes containing chlorohexidine, cetylpyridinium and antihistamines have also been named as the culprits of teeth discolouration.

While certain antibiotics such as Tetracycline and Amoxicillin are safe to use by pregnant women, they can stain the teeth of an unborn child. They also cause stains in young children.

Medical Treatments

Radiation treatments, such as head and neck radiotherapy and chemotherapy, can also cause a tan. These treatments can cause the enamel to weaken to the point that dark foods or drinks are more likely to stain the teeth.


When you are a healthy child you get away with more but as you age, the enamel on the teeth will become thinner, and more translucent as we age. This will reveal the yellowish color of the dentine underneath. Years of eating and drinking can also wear away the enamel on our teeth. Yellowed teeth can make a person appear older than they really are.

Years of grinding our teeth and chewing can strip away the outer layer, can reveal the yellowish dentine underneath.

5 Common Myths about Natural Teeth Whitening

Today, several natural teeth whitening methods are advertised online (via Facebook, Instagram, etc.) and in magazines. Good examples of such procedures include lemons, oil pulling, and charcoal, which are all DIY techniques. However, not everything on the internet works, especially natural teeth whitening solutions. The mistake many people make is that they think all-natural ingredients are good for their teeth and smile. However, many people are unaware that most of the ingredients used for teeth whitening can wear away the enamel over time.

This article aims to expose you to some of the most common myths about whitening teeth. Some of them could be a real shocker. They could be remedies you may have tried in the past. Let’s get started.

5 Common Myths about Natural Teeth Whitening

Common Teeth Whitening Myths

Whitening Toothpaste

We come in contact with these so-called whitening toothpastes almost every day. They are produced by many companies and often sold to us are higher prices compared to standard toothpastes. Stop wasting your money on these products because the chemicals needed to whiten the teeth effectively must be in contact with the enamel for a long time. Since you brush and wash your teeth in minutes, the whitening agent in the toothpaste won’t get the chance to do anything.

Coconut Oil

We use coconut oil in making smoothies, cooking, as a hair moisturizer, and on our face and body. In 2015, coconut oil sales rose to $239 million – primarily because of its presumed health claims. For example, many believe that swishing coconut oil in the mouth can produce a health treatment called “oil pulling,” which can whiten the teeth. However, till date, no scientific proof has been made to back the claim that coconut oil can whiten teeth.

Lemons and Strawberries

Many patients use lemon juice or crushed strawberries to whiten their teeth. However, this method may seem effective at first, but the acid in the fruits gradually wear away the enamel over time. The damage caused can lead to other dental problems in the future.

Activated Charcoal

 Activated charcoal is a black powder which comprises olive pits, peat, slowly burned wood, coconut shells, and other natural ingredients. However, just because they are natural products doesn’t mean always mean they are healthy.

There has never been any scientific backing to prove that activated charcoal can whiten the teeth. In fact, this product acts as an abrasive, which wears away the protective layer of the teeth revealing the yellow dentin beneath. This action makes the teeth look yellowish rather than whitish and increases teeth sensitivity and damage. After all, your goal is to whiten your tooth enamel and not weaken it.

Lemon Juice and Baking Soda

Although eating fruits is good for your health, allowing an acidic fruit juice to sit on your teeth for a long time can be dangerous. The acid in the lemons can gradually dissolve the outer layer of the teeth. Together with the abrasiveness of the baking soda, this combo can accelerate enamel wear and loss. Our enamel not only makes the teeth white but protects the sensitive layer of dentin underneath. Once the enamel wears away, your teeth will become vulnerable to sensitivity and decay.

Another common myth is the use of baking soda to whiten teeth. However, unlike toothpaste, baking soda is abrasive and can wear away the enamel over time.


How do you whiten your teeth effectively?

Maintaining white teeth is relatively easier than you think. According to the Australian Dental Association, you need to brush your teeth twice daily and floss once each day. Book appointments with your dentists for teeth cleaning and oral examination at least once every six months. The above recommendation would quickly help you get rid of tartar and plaque from your teeth, thereby giving you a white and attractive smile.

Reduce your intake of coffee, tea, and other staining beverages that can dull your smile. Also, stop using products containing tobacco as they can stain your teeth over time. Maintaining good oral hygiene is the most effective Home Remedy for whitening teeth.
