Actually, I will discuss the possible ways to target only the discolored tooth that causes us problem.

By doing so, you will be able to whiten back that tooth so it will have a similar shade as the other teeth around.

You should approach it this way when the discoloration is very obvious!

1. Teeth Whitening Pen

Teeth whitening pen is one of the most underused whitening products as not many people seem to be confident about using it.

However, this is not totally true! You can easily find some legit and trustworthy whitening pens that would do the job for you.

What makes from using this whitening product a successful process is the fact that it is really easy to use.

Using trays or mouth guards combined with whitening gel is also a very common way to whiten teeth effectively.

In this case you should choose a quality whitening gel. Then fill the tray or mouth guard before applying it on your teeth.

After that, you should keep it for about an hour on your mouth, depending on the product instructions, and then you can rinse or brush your teeth afterwards.

You are probably wondering how to use that to whiten just one tooth, right?!

Yea, actually, you can fill in tray the place of the discolored tooth with the whitening gel before applying it. So you will manage to apply the gel only on the discolored tooth.

If you want to make the process even more successful, you can opt for custom made trays from your dentist. They cost a little bit more than the regular ones. Otherwise, you can just opt for good trays on the market.

If you want to speed up the process a little bit you can use LED lights.

3. Miswak

If you’ve ever wondered how our ancestors use to brush their teeth, you’ve got your answer right here!

Actually, Miswak is the oldest toothbrush in history that our ancestors used to clean their teeth naturally.

I’ve written a complete guide about Miswak and its ability to whiten your teeth that you can check it Right HERE!

This is an obscure way that you can opt for! In fact, unlike regular toothbrushes, you can use Miswak literally whenever you want without any side effect whatsoever.

So you can apply Miswak only on the tooth that causes problem several times a day and you should notice positive results over time.

The only downside to this is the fact that you won’t get results overnight! As, it takes time, probably several weeks or even few months before you start noticing significant results.

4. Root Canal

Root canal is a direct treatment that you can have in the dentist office to relieve dental pain within a single tooth. Thus, this can save it from dying.

This option is mainly for a grey tooth due to inflammation or infection!

During the treatment the dentist removes the pulp in the tooth then cleans the root canal before shaping it.

5. Pulp bleaching

As I’ve said before root canal is an effective way to help grey teeth getting back to their white color.

Yet sometimes even if this treatment is done properly and successfully the tooth doesn’t turn white. It rather stays grey!

In this specific case, you may ask for a highly qualified dentist advice to have pulp bleaching.

6. Fillings

Sometimes tooth decay may lead to single tooth discoloration that tends to the grey, brown or even beige color.

In this case, you should start treating the decay by removing it within dentist assistance then replacing the cavity with white filling.

Don’t forget to ask your dentist to prepare white fillings with the same shade as the decayed tooth. Thus your tooth will look normal and white.

7. Veneering

This is another common way to make your discolored tooth white directly. In fact, you can use it to cover the discolored part of the tooth by a veneer with a proper shade.

If the tooth is completely discolored, you may even opt for crowns to cover the whole tooth!

8. KöR Whitening

Not many dentists practice this whitening strategy as it is an advanced one. It actually helps removing the most difficult stains that conventional methods can’t really do much about it.

Especially those due to some kinds of antibiotics exposure like Tetracycline!

How to whiten one tooth? (Indirect Way)

This is the second approach that you could opt for.

In fact, if the discolored tooth is not very noticeable, not really tending to the grey color and the shades difference with the other teeth doesn’t exceed 5 or 6 shades; you can definitely opt for this approach!

Thus, the shade of the discolored tooth will match the other teeth over time.

9. Teeth Whitening Strips

Teeth Whitening Strips is one of the easiest ways to whiten your teeth effectively. Indeed, the potential results you may possibly get are really good and may even look professional.

Usually this whitening product doesn’t really cost a lot (under 50 bucks or so). And the period of treatment is really very short (2 up to 3 weeks).

Plus, it is not that hard to find a legit brand selling this product (Crest is probably the best one in my opinion).

The tooth sensitivity is not really an issue, especially if you choose a good brand, as they usually include some enamel-safe ingredients to lower the risks as much as possible.

10. Constant Cleaning

You should keep cleaning your teeth on a daily basis. This is a key factor toward avoiding tooth discoloration!

If you’ve got a slightly discolored tooth, constant cleaning would be a great way to whiten it pretty easily.


Personally I brush my teeth at least twice a day, sometimes more if I eat more than usual. By brushing you keep your mouth clean, fresh and healthy.

Otherwise, your mouth will keep accumulation foods residue that will form stains, plaque or even tartar on your teeth.

Thus, your teeth won’t look good at all which would affect your smile.

As far as I am concerned the best way to approach brushing is by opting for:

  • Fluoride free toothpaste.
  • Reliable electric toothbrush.

You can check this top 10 fluoride free whitening toothpastes to have an idea about the best brands in the market today.

Plus, I recommend using an electric toothbrush as its ability to remove plaque from each tooth individually is highly effective.

100 times more effective than a manual toothbrush!

Oral-b 8000 Electric toothbrush is by far the most reliable one …


When I look around, I rarely notice people flossing or even considering this dental cleaning aspect at all.

Actually, this is an untapped tooth cleaning practice that few people really care about.

Yet, it is probably as important as brushing your teeth if not more important. Indeed, by flossing you remove obscure stains in between each tooth and the next one which makes each tooth look whiter.

Of course you can use a regular dental floss which could be just fine. However, if you want to take the process to the next level you really should think about trying a reliable water flosser.

As it is much easier to use, much more effective and safer for your teeth and gums.

Proper Nutrition

If you’ve one discolored tooth and keep eating unhealthy foods like:

  • Fast food.
  • Soda.
  • Too much coffee.
  • Alcohol.

That tooth would be even more discolored and others would be as well!

Even if you adopt the best whitening methods but keep consuming non-friendly foods for your teeth you will go literally nowhere.

So it is very important to avoid these kinds of foods as much as possible and including healthy ones like:

  • Apple.
  • Carrot.
  • Strawberry.
  • Olive Oil.
  • Coconut Oil.
  • Cheese.
  • Sesame Oil.
  • Turmeric.
  • Nuts.
  • Seeds.

And much more, the list goes on and on.

Try to include some of these elements in your next shopping list and you will notice the difference!

11. Whitening Home Remedies

Home remedies are also a great way to approach the one tooth whitening process. You’ve got many options that you can choose from!

Below I list 3 different ones which are the best you could possibly opt for:

Baking Soda

Brushing with baking soda will help you removing surface stains built on the discolored tooth pretty easily. In addition, it has some other good benefits like plaque removal and mouth pH adjustment.

You need to keep in mind that baking soda is a mild abrasive, so you should not consider it as a substitute to your regular brushing.

You should rather brush with it twice a week or so depending on what you are mixing with it (strawberry, lemon juice or just water).

You can check this complete guide on baking soda as a teeth whitening agent. You will learn how to do it properly without much risk.

Activated Charcoal

Just like Baking soda, activated charcoal is a very powerful and reliable way to whiten your tooth effectively.

In addition to its ability to remove extrinsic stains, tartar and to adjust your pH mouth indicator, it helps your mouth develop good bacteria and erase the bad ones.

Bad bacteria usually produce acid that causes stains, plaque and tartar. This leads pretty often to gum issues like gingivitis!

If you look around you will find many activated charcoal based products to whiten teeth. Such as whitening toothpaste, powders or even tablets.

The only thing you need to keep in mind is that you should use it once a season or sometimes once a year to avoid any potential risk.

This full guide will help you understand more this method and what it brings to the table.

Teeth Whitening 4 you

This is a program I’ve talked about couple of times in this Blog as I still didn’t find any similar one in the Internet so far.

In fact, it teaches you how to prepare whitening home remedies at home using cheap and completely natural ingredients.

Some of these ingredients are already available in your kitchen such as olive oil!

It was prepared by a former dental practitioner (Lucy Bernett). She has had around 17 years of experience in the subject and took advantage of that to write this concise e-book.

I’ve written a highly detailed review about this natural whitening program to give you as much information as possible on what to expect.

12. Laser Teeth Whitening

This is probably the most expensive in-office teeth whitening method you can possibly have. Yes, it is highly effective if you have that one tooth discoloration issue.

In fact, the principle of this method is whitening your teeth one by one separately regardless if they have different shades.

Yet, I have some concern about this method:

  • Very expensive unless you’ve got access to a fat budget.
  • I am not totally sure whether it fits those with tooth sensitivity.
  • Once you’ve had a laser whitening session it is totally forbidden to consume any food with a potential staining ability for 24 up to 48 hours. Otherwise you risk messing everything up.

Causes of single tooth discoloration

Being aware of single tooth discoloration is important. It is actually the first step towards preventing the one tooth discoloration!

Below some potential causes that could lead to that:

1. Genetics

Due to genetics some people may have a tooth or couple of teeth with a different color like grey, brown or beige.

2. Teeth injury or Trauma

Because of an accident (God keeps you safe) it is possible to have a tooth injury. This could lead to nerve malfunction so the injured tooth won’t receive the blood supply.

As a consequence it will become grey!

If something like that happens to you, go visit the nearest dentist to anticipate any further damage.

3. Amalgam fillings

Amalgam fillings or silver fillings may lead to single tooth discoloration. In fact, due to its composition (50% mercury) the fillings may release some mercury from it.

Thus, the tooth may start looking discolored as time goes on.

4. Tooth Decay

Tooth decay is another factor that may influence the white color of a given tooth. Indeed, due to tooth decay it may look brown or beige.

In this case dentist intervention is very important to remove the decay and replace it with appropriate white fillings.

5. Thin Enamel

Sometimes enamel covering a specific tooth tends to be thinner over time. This may be caused by enamel erosion or even acid exposure.

So, the inner layer which is the dentin will be more visible. This would influence the color of the tooth.

6. Dentinogenesis Imperfecta

This is pretty rare but happens sometimes. It is actually a growing malfunction that prevents a tooth or couple of teeth from its natural development.

Thus, the tooth tends to look weak and pretty discolored!


Hopefully, you’ve got all your answers on how to whiten one tooth!

Keep in mind that depending on how that tooth is discolored you should decide on how to approach whitening it.
