Although DIY bleaching kits have recently become very popular, their domestic use often carries great risks. To stay safe, it’s best for your patients to leave teeth whitening to the professionals. But what if they insist? Luckily, there is a safe solution they can use. It’s called enzymatic whitening, and here’s how it works.
For the home user, abrasive or chemically aggressive whitening toothpastes and bleaching kits can do more harm than good, especially if used improperly. Enzyme-based products, however, can be used safely every day and in the long term to regain natural tooth colour, and to maintain it after professional bleaching.
What’s more, if the formula is right, enzymatic toothpastes not only improve the appearance of your patients’ teeth, but provide additional protection for the enamel as well.
The ‘Be you’ toothpaste by Curaprox is one of such products, and we’ll use it as an example to explain how the enzymatic reaction works and what a safe yet efficient toothpaste for home whitening should contain.
Read on to understand what happens in the patient’s mouth when enzyme-based products are used, and what exactly is responsible for its effects.
The enzymatic reaction: when enzymes and sugars meet oxygen
The enzymatic reaction starts as soon as the toothpaste meets air. Two ingredients – glucose oxidase enzyme, which can be found in honey, and dextrose, a simple sugar made from corn – react with each other and with the oxygen in the air. Though technically a sugar, dextrose is only present to start the reaction and serve as nourishment for the enzymes, leaving no harmful residue.
The result of the enzymatic reaction is the creation of two active ingredients: hydrogen peroxide and gluconic acid.
The enzymatic reaction starts by glucose oxidase enzyme and dextrose reacting with each other, and with the oxygen in the air. No dextrose is left over.
This all-natural process results in hydrogen peroxide and gluconic acid being created.
Besides the main reaction, the ‘Be you’ toothpaste also contains hydroxyapatite, which provides additional whitening through protecting the enamel.
Gentle whitening: hydrogen peroxide + hydroxyapatite
Hydrogen peroxide deposits one of its two oxygen particles into the tooth enamel, resulting in a physical reaction: when light reflects off the enamel, it appears whiter. The remaining particles of hydrogen peroxide naturally dissolve, as they cannot survive in the mouth on their own.
In fact, the enzyme components are already naturally present in the mouth and saliva. Enzyme-based toothpastes simply further support the process of their creation, resulting in a very gentle whitening effect. As such, the enzymatic whitening effect is safe to be present in a risk-free, daily-use toothpaste.
Hydroxyapatite smoothes and brightens the enamel and also closes openings that expose dentine beneath your patients’ enamel. This way, hydroxyapatite prevents staining food particles from getting into microscopic enamel fissures and reduces the sensitivity of exposed tooth necks.
Combating bacteria: gluconic acid
Gluconic acid is the second product of the enzymatic reaction and it has protective qualities. It’s a natural fruit acid that inhibits the growth of microorganisms. In spite of containing acids, the PH value of the ‘Be you’ toothpaste is rated at 6–6.6, staying well above the safe minimum of 5.5.
Extra tooth protection: three more ingredients
While the main enzymatic reaction produces gluconic acid that protects teeth and gums against bacteria, and the addition of hydroxyapatite helps keep sensitivity down, that’s not all a home-whitening toothpaste should do. The more protective elements it contains, the better – the ‘Be you’ contains three extra ingredients that further assist tooth protection:
Hypo-thiocyanate. As your patient brushes, hydrogen peroxide reacts with the lactoperoxidase enzyme contained in their saliva, and with thiocyanate, an additional ‘Be you’ ingredient. This results in the production of hypo-thiocyanate, which has a strong antibacterial effect. Although saliva naturally exhibits antibacterial properties, this is significantly improved by hypo-thiocyanate.
Xylitol, or birch sugar, in the toothpaste reduces the formation of biofilm and protects against tooth decay.
Fluoride is very effective at combatting acid-producing bacteria and helps remineralise the enamel.
Why is it good for your patients?
Enzymatic whitening is a perfect solution for those of your patients who would like their teeth whiter, but don’t want to opt for either professional whitening or aggressive DIY bleaching kits.
What’s more, enzyme-based products are capable of maintaining the colour of your patient’s teeth after a professional bleaching, prolonging its effects in a safe, gentle and sustainable way.
To keep your patients safe and help their home-whitening efforts, an enzyme-based toothpaste for daily use is a good choice. And if it contains some extras on top, it might as well become their new daily routine.

DIY Bleaching Kits and their Risks
The article mentions that DIY bleaching kits have become popular but can carry great risks when used domestically. It suggests that it is best for patients to leave teeth whitening to professionals to ensure safety.
Enzymatic Whitening as a Safe Solution
The article introduces enzymatic whitening as a safe alternative for home users. It states that abrasive or chemically aggressive whitening toothpastes and bleaching kits can do more harm than good if used improperly. Enzyme-based products, on the other hand, can be used safely every day and in the long term to regain and maintain natural tooth color after professional bleaching.
Enzymatic Reaction and its Effects
The article explains how enzymatic whitening works. It states that the enzymatic reaction starts as soon as the toothpaste meets air. Two ingredients, glucose oxidase enzyme (found in honey) and dextrose (a simple sugar made from corn), react with each other and with the oxygen in the air. This reaction creates two active ingredients: hydrogen peroxide and gluconic acid. The enzymatic reaction is an all-natural process that results in gentle whitening.
Hydrogen Peroxide and Hydroxyapatite
The article describes the gentle whitening effect of hydrogen peroxide. It explains that hydrogen peroxide deposits one of its two oxygen particles into the tooth enamel, resulting in a physical reaction that makes the enamel appear whiter when light reflects off it. The remaining particles of hydrogen peroxide naturally dissolve in the mouth. The article also mentions that the 'Be you' toothpaste contains hydroxyapatite, which provides additional whitening and helps protect the enamel.
Gluconic Acid and Bacterial Protection
The article discusses gluconic acid, which is the second product of the enzymatic reaction. It states that gluconic acid is a natural fruit acid that inhibits the growth of microorganisms. The 'Be you' toothpaste, mentioned in the article, contains gluconic acid to provide bacterial protection. The pH value of the toothpaste is rated at 6-6.6, which is above the safe minimum of 5.5.
Additional Protective Ingredients
The article mentions three additional ingredients in the 'Be you' toothpaste that assist in tooth protection. These ingredients are:
- Hypo-thiocyanate: This ingredient reacts with hydrogen peroxide and an enzyme called lactoperoxidase in saliva to produce hypo-thiocyanate, which has a strong antibacterial effect.
- Xylitol: This ingredient reduces the formation of biofilm and protects against tooth decay.
- Fluoride: This ingredient is effective at combating acid-producing bacteria and helps remineralize the enamel.
Benefits of Enzymatic Whitening
The article highlights the benefits of enzymatic whitening for patients who want whiter teeth but prefer not to opt for professional whitening or aggressive DIY bleaching kits. Enzyme-based products can help maintain the color of teeth after professional bleaching in a safe, gentle, and sustainable way. The article suggests that an enzyme-based toothpaste for daily use, such as the 'Be you' toothpaste, can be a good choice to support home-whitening efforts. I hope this information helps you understand the concepts discussed in the article. If you have any further questions or need more information, feel free to ask!
