Yellow teeth myths

Many of the ideas people have about yellow and white teeth are not necessarily true. Have a look at the following teeth yellowing myths and see if any pertain to you:

Myth 1: Teeth are naturally bright white

Are teeth naturally yellow?
Translucent enamel allows yellow dentin to show through, resulting in tooth yellowing

A few lucky people may be blessed with pearly white teeth, but most people's teeth are naturally a couple of shades darker. In fact, really bright white teeth can actually look quite unnatural. Natural teeth are usually tinged with yellow or grey.

To understand the reason why, let's take a look at the anatomy of the tooth:

On the outside, we have a layer of enamel, which is a blueish-white color. But enamel is translucent, which allows the layer of dentin below to show through. Dentin is a darker yellow color, and this is what gives teeth an off-white appearance.

So, it's really the shade and thickness of your tooth enamel which determines the color of your teeth. If you brush and floss every day but your teeth are still yellow, it may just be that they are naturally that shade.

Myth 2: Yellow teeth are unhealthy

This is a myth pushed on us by companies who want people to spend hundreds of dollars getting a “perfect” Hollywood smile.

Although yellow plaque deposits and heavy staining are not healthy, it's quite possible for perfectly clean and healthy teeth to be a shade of yellow. Teeth whitening procedures often work by stripping or penetrating the outer layer of enamel, which weakens teeth if repeated numerous times. So in many cases, off-white teeth are stronger than bright white ones, as long as they are kept clean.

Of course, you may still want to improve the esthetic appearance of your smile by whitening your teeth, and we have some more information about that below.

Myth 3: You will get yellow teeth with braces

Wearing braces requires extra care so you don't get yellow teeth with braces

Some people do end up with stained teeth after braces, but it's not necessarily the braces themselves that are to blame. Bacteria can easily build up around the brace brackets so it's important to be extra careful with cleaning your teeth and flossing during this time. If you keep up a good oral hygiene routine, wearing braces doesn't have to result in discolored teeth.

If you're worried about fixed braces discoloring your teeth, you could consider a different style of braces. Lingual braces are fixed behind your teeth so any marks they leave are hidden inside your mouth. Alternatively, “invisible” braces are removable so you can clean your teeth as normal.

On a side note, if you wear metal braces with colored bands, did you know the color you choose can make your teeth look brighter or more yellow? Read more in our full article on colored braces.

So why are my teeth yellow?

So, your teeth are yellow.

The good news is, you are not alone in having teeth that are yellow or off-white, and it might not necessarily be a bad thing.

But why are your teeth yellow? In the next section, we'll look at the things that may be responsible for your teeth yellowing.

Tobacco stained teeth

Smokers are prone to stained teeth

Smoking makes your teeth yellow because of the tar, nicotine, and other chemicals carried in the smoke. These seep into the pores in your tooth enamel, staining its natural color.

A study conducted in 2005 found that 28% of smokers had moderate to severe levels of tooth discoloration, compared to 15% of non-smokers. The study also revealed that smokers were generally less satisfied with the state of their teeth.

E-cigarettes may not discolor teeth to the same degree, but they still contain nicotine which becomes yellow when it mixes with oxygen.

There are other oral health problems associated with smoking, too. For example, nicotine causes gums to recede and can lead to gingivitis and periodontitis.

Bad oral hygiene

If you notice a yellow buildup on your teeth, it's probably plaque or tartar. Plaque forms when bacteria from food and drink particles aren't cleaned properly from your teeth. Over time, plaque hardens to form tartar, which can only be removed by a dentist or hygienist.

This yellow coating can form on or around your teeth if you don't brush often enough or thoroughly enough. Not only does it look bad, but it also contributes to bad breath and a whole load of other oral health complications.

Your diet

It shouldn't come as a big surprise that the things you put into your mouth have an effect on the color of your teeth. If your teeth aren't white, you may be suffering from:

Coffee stained yellow teeth
Do you have coffee-stained teeth?
  • Coffee-stained teeth
  • Tea-stained teeth
  • Red wine-stained teeth
  • Curry stains
  • Tomato sauce stains
  • Berry stains
  • Soy sauce stains
  • Balsamic vinegar stains
  • Beetroot stains

There are other foods and drinks which, although they don't cause staining themselves, contain acids that eat away at your tooth enamel. This reduces the ‘whiteness' of your teeth and also leaves them more susceptible to staining. Watch out for:

  • Fizzy drinks (heavily colored ones can also cause stains)
  • Citrus fruits and juices
  • Sports drinks
  • Sugary foods
  • Artificial sweeteners
  • White wine and many other alcoholic drinks

Rinsing your mouth with water after consuming these products will help minimize the damage from any acid.

Aging and yellow teeth

As if getting older weren't bad enough, it's natural for your teeth to become yellow as you age. This is because the protective enamel layer becomes thinner, revealing more of the yellow dentin underneath.

Genetics and yellow teeth

If you have had yellowish teeth all your life, your parents may be to blame. Genetic variances can affect tooth color and enamel porosity—and more porous enamel is more likely to stain.

Medication or illness

Some antibiotics such as amoxicillin and tetracycline can cause stained teeth, especially in younger children.

Drugs prescribed to adults for allergies and high blood pressure may also have this side effect. Speak to your doctor if you're concerned about this.

Certain illnesses, particularly those that affect the liver, can result in discolored teeth. Patients who undergo chemotherapy or radiation treatment for cancer may also find their teeth turning a brownish hue.

How to get rid of yellow teeth

Wondering how to get rid of stained teeth? Turning your teeth from yellow to white is often easier said than done. However, if you're wondering how to fix yellow teeth, or how to fix stained teeth, there are several approaches you can take depending on your budget, the results you want, and how quickly you want to see a difference.

How to clean yellow teeth

Want to help your yellow teeth become white? You should visit your dental hygienist every six months for a scale and polish unless your dentist recommends otherwise. Getting your teeth scaled involves removing any tartar build-up and then polishing the surfaces of your teeth with special instruments.

You might be surprised at how much brighter your teeth appear after this. But if you want more drastic results, you'll need to look at your options for teeth whitening.

Before you do, you might want to watch this short video where a dental assistant explains the possible side effects of tooth bleaching:

The side effects of bleaching teeth include sensitivity during the bleaching process, a tingling sensation when the bleach has penetrated the enamel and weakening of the enamel due to over-bleaching. Avoid harmful side effects of teeth bleaching by consulting a general dentist with tips from a licensed dental assistant in this free video on oral hygiene.

How to whiten yellow teeth with a home whitening kit

There are many affordable and effective ways to whiten your teeth at home. You can buy strips, pens, bleaching trays, LED kits and more in your bid to brighten your smile.

Naturally, each of these methods varies in its cost, effectiveness, and ease of use. Generally speaking, home treatments won't be as effective on badly yellow-stained teeth as professional treatments, unless you opt for an option on the higher end of the price range. Thankfully, even these options are much more affordable than in-office whitening procedures.

Veneers for yellow teeth

If your teeth are not just discolored but also crooked or chipped, you may want to kill two birds with one stone by getting veneers. These thin covers are placed directly onto your existing teeth. They can be made to match your natural teeth if you just need one or two, or you can transform your smile with veneers across all your visible teeth.

How to clean stained teeth

Whether you have coffee-stained teeth or naturally yellow teeth, you can help prevent any further yellowing by taking good care of them. This means brushing your teeth properly twice a day and flossing at least daily. Use a fluoride toothpaste as this helps strengthen enamel. You can also use mouthwash, but don't rinse immediately after brushing since this can wash the fluoride away.

And remember that list of foods and drinks that stain or damage teeth? Try to limit your consumption of these, or at least rinse your mouth with water after you have had them.

What to do if your kids have yellow teeth

Do you have a child or toddler with yellow teeth? Keep in mind that a child's milk teeth are usually whiter than their permanent teeth. Don't be alarmed if their first adult teeth seem quite yellow in comparison to the remaining baby teeth.

Help your kid's yellow teeth with healthy choices

Whether your child has yellow baby teeth or yellow permanent teeth, discolored teeth in your child may be due to some of the same reasons as adults' discolored teeth, i.e. diet, poor oral hygiene, genetic factors, medications, and illnesses.

Take the same precautions as you would for yourself; brush well twice a day and limit sugary snacks and other foods that may damage enamel. If you have trouble brushing your child's teeth thoroughly, consider investing in an electric toothbrush which might make the task more enjoyable.

Also, take your child to the dentist for regular checkups so any dental problems can be addressed early on. If you are concerned about the shade of your child's teeth, mention it to your dentist at your next visit. Avoid using any whitening products, even natural ones, on your child, unless your dentist recommends you do so.


Our teeth can be yellow for a variety of reasons, whether it's their natural color, or it's due to the thinning of enamel or a build-up of plaque. If your teeth are healthy but you'd like them to be whiter, there are a variety of things you can do, including professional whitening, home whitening kits or using a whitening toothpaste. Remember that teeth aren't naturally completely white, but you should make sure to regularly visit a dentist so they can diagnose any problems that might go beyond the cosmetic.


What causes yellow teeth?

teeth yellow
Are you wondering why your teeth are so yellow?

So, why do teeth turn yellow? Your teeth yellowing may be caused by a number of factors including:

  • Smoking
  • Diet
  • Genetics
  • Age
  • Medication

Normally, teeth are naturally a bit yellow, and it doesn't necessarily mean that they aren't clean and healthy.

What are ways of whitening yellowed teeth naturally?

If you're wondering how to make teeth white naturally from yellow, there are a number of remedies available, such as:

  • Activated charcoal
  • Coconut oil pulling
  • Baking soda
  • Apple cider vinegar

To be safe, you should ask your dentist before using any of these to whiten your teeth, and ask them about proper technique as well.

Can I have naturally yellow teeth?

Natural teeth color
Your normal teeth color might be a bit yellow

Are teeth naturally yellow? You may be relieved to know that it is normal for teeth to be a bit yellow. That's because teeth are partly made of yellow dentin, which is covered by translucent enamel. Many people with great oral hygiene habits may still have teeth that aren't totally white, because the yellow of the dentin is showing through the enamel.

What if my toddler has yellow teeth?

If your toddler or child has yellow baby teeth, this may be a sign that better oral hygiene is required. Baby teeth are normally whiter than adult teeth, and this is an important time to implement proper teeth cleaning habits.

Why do I have yellow spots on my teeth?

If you have spots or patches of discoloration on your teeth, it may be due to the following factors:

  • Hypocalcification: When the tooth enamel is not fully formed, the affected tooth may be more sensitive.
  • Fluorosis: Too much fluoride received during childhood.
  • Demineralization: Calcium phosphate is the principal part of the mineral on teeth, and it may start to dissolve due to too much plaque. If this happens, you may experience some discoloration.

Why won't my teeth whiten even though I'm brushing?

You might have yellow stains on teeth even if they are clean and healthy

Sometimes brushing isn't enough to turn yellow teeth to white. If you brush and floss your teeth twice a day, and your teeth are still yellow, it may just be the natural color of your teeth. Naturally yellow teeth is not a medical concern, rather it is simply cosmetic. If this is your case, and you really want whiter teeth, you may want to consider teeth whitening.

Will I get yellow teeth after braces?

Braces themselves will not discolor your teeth, but if you don't clean properly around the brackets, you may get plaque buildup.

How do you whiten between teeth?

You can whiten between your teeth the same way you would whiten the fronts of your teeth: Maintain good oral hygiene and consider home whitening or professional whitening remedies.
