The biggest question on your mind is do they actually work? Will Colgate optic white whiten your teeth or is there no difference when compared to their regular line of products?

We’re going to do a deep dive into how teeth whitening works and whether or not each of these products do what they allege to do. Buckle up because we’re taking you on a Colgate whitening journey.

The entire suite of Colgate Optic White products

Colgate has packaged all of their optic white products into a bright red packaging to help you distinguish them easily. It consists of multiple toothpaste formulations, a whitening mouth rinse, and a whitening pen with a LED light.

These products differ based on their ingredients and how they are meant to be used. However, the end result is supposed to be the same in that they leave you with whiter teeth than when you started.

Does Colgate Optic White really work?

Colgate optic white does work because it does possess the ability to remove

from your teeth, thus making them whiter. It contains all of the whitening ingredients which are needed to whiten your teeth in toothpaste.

According to the American Dental Association (ADA), the accumulation of extrinsic and intrinsic stains are what makes teeth yellow.

  • Extrinsic stains can be removed mechanically by brushing with abrasives.
  • Intrinsic stains require a chemical agent such as hydrogen peroxide that can diffuse through the tooth to oxidize them.

All whitening toothpastes utilize an abrasive system so they can all remove extrinsic stains by default. Different toothpastes may use a different abrasive but they all function the same way by mechanically abrading stains. That is essentially how all whitening toothpastes work.

However, not all whitening products contain hydrogen peroxide which is necessary to oxidize intrinsic stains. The only way to get rid of the intrinsic stains is via a chemical agent that can traverse through the tooth to reach these deeply embedded internal stains. Peroxide works wonders in that it can also get rid of extrinsic stains as well.

Since teeth become yellow due to a combination of extrinsic and intrinsic stains, the whitening products that can remove both would obviously be more effective. Logically that makes sense because if you’re only able to get rid of one type of stain but not the other, then its not as effective! That is the reason why your teeth may still be yellow despite brushing everyday.

Therefore the question is which of the optic white products remove what type of stains?

Which Optic White product removes which stains?

Surprise surprise but not all of the Colgate optic white products will get rid of both extrinsic and intrinsic stains. Some of them will only remove the extrinsic while leaving the intrinsic ones intact.

The determinant factor for whether it can oxidize the internal stains is if it contains peroxide. In addition to that, the efficacy of the oxidation is highly dependent upon the concentration of hydrogen peroxide.

Now without further ado, let’s explore what each of these products have to offer and what they can do to make your teeth less yellow.

Optic White stain fighter whitening toothpaste

This toothpaste is marketed as their non-hydrogen peroxide product. This dentifrice is supposed to remove 6x more stains from their micro-polishing action. In other words, the abrasive system within it should be 6x more effective at getting rid of extrinsic stains.

What stains does it remove? – Extrinsic only.

Optic White charcoal toothpaste

Since activated charcoal teeth whitening has been a trend, Colgate has decided to release their own iteration of it. Similar to the stain fighter, it alleges that it can remove up to 6x more stains due to their micro-polishing ability. In other words, it uses an abrasive system.

Optic White advanced whitening toothpaste

The first toothpaste that contains hydrogen peroxide. The official statement is that it can whiten inside and out, which implies that it can remove more than just extrinsic stains. It will result in teeth that are four shades whiter after six weeks of bi-daily use.

Optic White pro series LED kit

The LED kit is more of an adjunct product to their optic white line. It only contains the LED light with the tray. You’re supposed to use it in conjunction with the whitening pen. The purpose of this is to imitate the trend of ZOOM whitening products which utilizes a LED light to speed up whitening.

How do you use it?

  2. Insert LED tray into your mouth.
  3. Activate it for 10 minutes.
  4. Remove from your mouth and go to bed.
  5. Brush your teeth to remove residual whitening gel.

Optic White renewal toothpaste

The optic white renewal toothpaste is different than all the other products in that it can rebuild your damaged tooth enamel while simultaneously whitening them. It is able to make these claims because it actually contains the highest concentration of fluoride out of all of them.

The renewal toothpaste contains 0.18% fluoride ions which is more than the pro series that only has 0.13%. In comparison, even the optic white stain fighter toothpaste only has 0.15% fluoride ions while the advanced whitening has 0.12%.

Therefore it does indeed contain the most fluoride and can claim to repair your teeth the most out of the rest of the optic white line. This is their nod to how whitening toothpaste is not bad for your teeth!

Does it contain hydrogen peroxide? – The renewal has 3% hydrogen peroxide.

What stains does it remove? – Extrinsic stains and intrinsic stains.

How do you use it? – Brush for at least two minutes twice a day.

Colgate Optic White products ranked by whitening prowess

The most effective Colgate whitening product would be the Optic White pro series toothpaste since it contains the most hydrogen peroxide. It is also currently the best whitening toothpaste on the market.

Obviously the best whitening product would be one that can remove both types of teeth staining, extrinsic and intrinsic. The ones without peroxide can only get rid of the exterior stains while leaving the interior ones untouched. This automatically makes the peroxide based products superior.

Ranking from most effective at whitening to least: We’ll be reviewing all of them!

  1. Optic white pro series
  2. Optic white renewal / whitening pen
  3. Optic white advanced whitening
  4. Optic white mouthwash
  5. Optic white charcoal
  6. Optic white stain fighter

The LED kit is not ranked since it doesn’t actually contain any whitening ingredients. There is no peroxide nor is there any abrasives. It is only supposed to enhance the whitening pen’s effects.

The Verdict – Does Colgate optic white work in whitening your teeth?

The short answer is yes, they definitely do make your teeth whiter. All of them will remove extrinsic stains on your teeth but some of them can also get rid of the intrinsic stains. It all depends on whether or not they have peroxide within them.

The ones with peroxide will always be more effective than the ones without it since they can oxidize intrinsic stains in addition to abrading the extrinsic ones. After that, the next ranking factor would be, which one has the greatest concentration of hydrogen peroxide.

That is basically the formula we used to determine which optic white product is the most potent at making your teeth less yellow.
