Why Are My Teeth Yellow Even Though I Brush Them

So Why Are My Teeth Yellow Even Though I Brush Them Daily As Recommended?

So why do I have yellow teeth despite brushing?

You may just have naturally yellow teeth!

Just like the world’s population, every race and community has differing skin shades, eye color, and hair color. Our teeth also come in a variety of different shades.

If you have been following a good dental hygiene routine, it may just be that the natural shade of your tooth is less than a perfect white. Pure white is, in fact, a very rare natural phenomenon.

Even between siblings, the color will vary – one brother’s or sister’s teeth will be whiter than the other. It is simply a quirk of nature.

Genetics also determines the porosity of your enamel. The more porous your enamel is – the more likely it is to stain.

Can Yellow Teeth Become White?

Can yellow teeth become white

In most cases – yes!

Most stained and yellow teeth can be whitened.

You don’t have to live with yellow teeth forever. There are many ways in which you can whiten, lighten and de-stain your enamel.

First of all, you need to determine the reason why they are discolored.

Is it a quirk of fate?

Or are there other factors that come into play that you may not be aware of?

Yellow Teeth Causes

Let’s find out the reasons why your teeth are yellow and what you can do to prevent it from getting worse.

There are many factors that will influence the color.

If you are determined to address the issue of your teeth color, here are a few reasons why they could be discolored – besides genetics:

  1. Smoking
  2. Diet
  3. Aging
  4. Medication or illness

Some of these factors may be within your control, but others are not.

The ones that you can control are:



Smokers are more prone to having yellower teeth.

Why is this?

The nicotine, tar, and other chemicals that are carried in the smoke stain the natural color of the tooth.

Nicotine is known to become yellow when mixed with oxygen. When inhaled or chewed the chemicals settle into the small pores in your tooth enamel – thereby discoloring them.

Don’t be fooled – e-cigarettes still contain nicotine. So be vigilant.

Nicotine is also a cause of other issues such as gum recession, gingivitis, and periodontitis.



Your diet may be the cause of yellowing too.

There are certain foods if eaten regularly can create yellowing of the tooth enamel.

These include:

  • Coffee and tea
  • Red wine
  • Tomato sauces
  • Berries
  • Beetroot
  • Curries
  • Soy sauce
  • Balsamic vinegar

Coffee, tea, and wine are particularly high in something called chromogens. These stick to your teeth and create staining.

There are other foods and drinks that are high in acids that can affect the decay of tooth enamel:

  • Fizzy drinks
  • Citrus fruits and juices
  • Sports drinks
  • Foods high in sugar
  • Artificial sweeteners
  • White wine and many other alcoholic drinks

To help reduce the effects of acidic drinks or foods you can drink milk or plain water afterward. This will help reduce the acids eroding effect on the enamel.

Additionally, avoiding eating snacks between meals will allow your saliva to do its job and dilute the acids in your mouth.

If you have a dry mouth it is particularly advisable to follow the above advice. Drink milk or water after eating.

Alternatively, brush your teeth gently to counteract the acidity.



It is pretty obvious that the more you use your teeth, the more wear and damage is created.

With age, the outer layer of tooth enamel is slowly worn away.

This erosion can reveal the yellow dentin underneath.

The thickness of your tooth enamel determines how quickly this occurs.

Therefore, as you get older the more the color will change.

It is a natural phenomenon that everyone will experience.

Medication Or Illness

Medication or illness

Medication taken in the long term or in high doses can affect the tooth color.

Drugs that may be prescribed for allergies, high blood pressure, chemotherapy, radiation treatment, and anti-psychosis are not good for your teeth.

Some of these medications include tetracycline, amoxicillin, and doxycycline.

Some nutritional deficiencies may change the color of the enamel. So will an illness that affects the liver.

So consider if any of these drugs may be affecting you and your teeth. Perhaps consult your doctor about the effects your prescription drugs may cause on teeth.

Can You Whiten Yellow Teeth?

Most instances of yellow teeth are reversible.

A whitening procedure is the answer.

There are many different methods available to you – both at home and provided by your dentist.

So… when you ask – why are my teeth yellow even though I brush them? – think about what you can do to help your teeth with a small change of lifestyle.

The cause of the discoloration of your teeth determines the time it will take to whiten or lighten them.

Teeth that have a natural yellow shade will generally whiten in about 1 to 2 weeks. That is good news is it not?

On the flip side – tobacco stains can take 1 to 3 months to whiten.

Teeth that have been affected by medications will take longer – anywhere from 2 to 6 months.

These time periods are only estimates. The results will vary depending on how bad the staining is and what method of teeth whitening you have chosen to use.

Here’s wishing you all the best in whitening your teeth and getting a whiter, brighter, better you!


Why are my teeth yellow even though I brush them is a question that you are not alone in asking.

In fact, yellow teeth are very common.

So don’t despair.

There may be nothing wrong with your teeth, except for the fact that you don’t like the color.

Generally that is fixable. Just find the correct teeth whitening method that suits you.

Take into account if you have external reasons as to why your teeth are yellow, and choose accordingly.

And don’t forget to look after them properly after whitening!
