Discoloration of Teeth

Your teeth may discolor or stain because of what you consume regularly in your daily life.

These may appear as surface stains or as a change in the material of your teeth such as the enamel and dentin.

Surface stains are known as extrinsic stains.

A film of protein surrounds the tooth enamel.

As you eat and drink different foods, the pigmented residue ends up building in the protein.

This causes the teeth to stain and look yellow or brown in color.

Mostly it will look yellow because of the colored drinks like coffee, red wine or cola.

Though tobacco use may give you yellow or brown stains.

This includes chewing tobacco products and smoking.

Though, you can find solutions to this staining in home remedies, maintaining good oral hygiene like brushing teeth with a whitening toothpaste and flossing.

If your teeth are darker shades of yellow then you can try whitening products and a whitening treatment.

Though the other kind of stains occur below the surface and inside the tooth.

Hence, they do not stain outside on the exterior but inside the enamel.

Therefore, you cannot easily remove them through brushing or having good oral health.

You will rather require a professional teeth whitening session with a dentist to remove them.

There are also stains that occur on your teeth because of your age.

When you age, the tissue found under the enamel i.e. the dentin becomes yellow over time.

Furthermore, the enamel becomes thin too. Hence, the dentin becomes more apparent.

Age-related stains combine both extrinsic (surface) and intrinsic stains to yellow your teeth over time.

Thus, as you age, your teeth do not remain as bright and white as before.

Staining happens because of these causes:

Causes of Staining

  • Children using fluoride in their early years can result in staining their teeth intrinsically.
  • Colored foods and drinks such as berries, cola, coffee and tea can stain the enamel’s surface.
  • Tobacco use while smoking and chewing tobacco products like beetle nut can stain extrinsically.
  • Trauma to the teeth in children or adults can cause stains.
  • Illnesses and diseases in children under the age of 8 or even when in the womb can cause them to have yellow teeth
  • Treatments such as chemotherapy and radiation can stain your teeth when you take them.
  • Similarly, medicines such as antihistamines, medicines for high blood pressure and antipsychotic drugs can also cause your teeth to stain.

These are some of the causes that can stain your teeth from the surface enamel or inside the teeth.

You cannot treat all of them by brushing regularly.

If you maintain good oral hygiene but your teeth remain stained then it is time that you discover some other options.

Let’s find out what are those below!

How to Whiten Teeth At A Dental Clinic

You can go to a dentist at a dental clinic for both extrinsic and intrinsic stains.

They can also clean your age-related stains.

The best part is that you will get white and brighter teeth in less than 2 hours.

Hence, if you are looking for how to whiten teeth overnight or how to get white teeth in minutes then the answer is not in home remedies but at a dentist’s clinic.

The reason being that the peroxide gel (hydrogen peroxide or carbamide peroxide) with dentists is of a much higher concentration than that available in the home whitening kits.

Your dentist applies the gel to your teeth and places a mouthguard covering your lips so that the gel does not touch anywhere else i.e. the gums or lips.

Then a Blue light helps to oxidize the peroxide into oxygen which helps remove the stains and makes your teeth whiter.

They can either apply gel to all the teeth at once or they may treat one tooth at a time.

The two popular treatments at a teeth whitening clinic are Zoom Whitening and Laser Dental Whitening.

Zoom Whitening is a more effective treatment that treats all of your teeth at once in three 15 minute sessions.

You can get 8 times whiter shade in just an hour.

In laser dental whitening, the dentist treats each of your teeth separately.

If you are wary of sensitivity then you should go for laser dental whitening as it happens once and not thrice in 15-minute sessions.

Though, through both of these treatments, you will leave with a much whiter smile than what you had an hour ago.

The extent of whiteness also depends on the extent of staining.

It is hard to give a much whiter shade to heavily stained teeth.

Though, before going to a dental clinic, you may want to experiment with home remedies. Find them below!

One of the popular remedies is using baking soda and hydrogen peroxide.

Use Baking Soda to Remove Plaque

You must be wondering how to whiten your teeth with baking soda then?

Use A Few Drops of Apple Cider Vinegar 

Apple Cider Vinegar is useful in reducing weight however, it is not that great for it.

You can use a few drops of apple cider vinegar to also whiten your teeth.

Then rinse and squish it around your mouth thoroughly.

Later clean your mouth by brushing your teeth and gargling with water.

Apple cider vinegar does have a bleaching effect though, you should only use a small quantity as it can damage the enamel.

Oil Pulling Using Coconut Oil 

Oil pulling helps to remove bacteria and plaque inside the teeth that stain them.

You just need to squish the oil around in your mouth for a few minutes without letting it touch the back of your mouth.

Also do not swallow it after squishing it as it now has the bacteria and plaque from your mouth.

Spit it after 10 minutes of squishing and clean your mouth with water.

Remember that coconut oil is solid at room temperature, hence, heat it first to liquefy it and then use it.

Other alternatives are sesame oil and sunflower oil that can reduce the chances of gum disease.

Using Activated Charcoal 

Charcoal quickly gained popularity for whitening the teeth and brightening the face.

However, there needs to be more research on this and people with sensitive skin should use it sparsely.

Though charcoal is an absorbent hence it removes stains.

It can also remove other bacteria and toxins from your teeth.

You can apply it directly to your toothbrush and be gentle with it. Brush it for 2 minutes on your teeth.

You can also make a mouthwash by mixing it with water.

However, make sure to use charcoal sparingly as it contains mild abrasives that can wear down your enamel.

Whitening Using Over-The-Counter Kits

Whitening kits available over-the-counter contain a certain concentration of peroxide.

These are not as strong as the peroxide gels at the dentist’s office but they are stronger than the home remedies.

If you use them regularly then you can see a difference in the shade of your teeth in a few months.

These include:

  • Whitening Toothpaste

Whitening toothpaste may contain a certain amount of baking soda or other whitening agents that will increase the whiteness of your teeth by one shade.

  • Gels, Trays and Strips

Certain whitening gels contain carbamide peroxide that you can apply directly to your teeth two times a day.

Another way to apply the gel is to use mouth trays with 10 to 38 percent of carbamide peroxide.

Apply the gel in the mouth trays and wear it for a few minutes daily.

Similarly, whitening strips are also worn over your teeth and they contain a whitening gel that comes in contact with your teeth.

  • Whitening Mouthwash

Mouthwashes and rinses containing hydrogen peroxide will have a whitening effect on the teeth.

You will not see results sooner than 12 weeks as the rinse has very less contact with the teeth compared to trays and strips.

Trays and strips may show results in a few days which will even last as long as 4 months.


These are all the answers to how to whiten teeth.

Dental procedures work the best followed by over-the-counter teeth whitening kits.

Home remedies will take the longest to show any change.

Consult your dentist before using any home remedy or home whitening kit as overuse of some may cause more harm to your teeth.

In fact, if you need whiter teeth that last for the longest time, why not get an in-office teeth whitening session?
