Artificial tooth enamel, also known as tooth enamel repair or tooth enamel restoration, refers to technologies and treatments that aim to strengthen, repair, or replace natural tooth enamel. Tooth enamel, as the outermost layer of the tooth, is crucial to dental health as it protects teeth from acid attacks and damage. Innovations in dentistry have developed various approaches to restore or replenish damaged or worn tooth enamel. These technologies and procedures offer hope for improved solutions to maintain and restore the structural integrity of tooth enamel. In this regard, artificial methods are playing an increasingly important role in modern dentistry to support dental health and extend the life of teeth.
What is tooth enamel?
Tooth enamel is the outermost hard layer that forms the visible surface of a tooth. It consists mainly of the mineral calcium phosphate (hydroxyapatite), a crystalline substance that is about 96% mineralized, and trace elements such as magnesium and fluorine. This structure gives tooth enamel its hardness and resistance to daily stress, such as chewing and acid attacks. The hook? The tooth enamel is extremely thin (1–1.5 mm) and unfortunately cannot regenerate itself. Once it is damaged, we have to live with the consequences. That's why it's extremely important to make sure that it stays intact.
Comparison between artificial and natural tooth enamel
The comparison between artificial and natural tooth enamel covers various aspects to better understand their properties and applications. Natural tooth enamel is characterized by its hardness, resistance to acids, and aesthetic properties. Artificial tooth enamel is designed to mimic or complement this natural protection and aesthetic.
In terms of hardness and resistance to acid attacks, some man-made materials can be similar to or even surpass natural tooth enamel. Research is focused on developing materials that can provide similar hardness and protection. However, there are still differences in terms of biological integration and behavior in the oral cavity that still need to be improved in artificial tooth enamel in order to achieve a truly seamless integration into the natural tooth material.
Intensive research is being carried out on artificial tooth enamel in order to achieve various goals:
Research into artificial tooth enamel aims to develop innovative materials and treatments that can replicate or complement natural tooth enamel to improve dental health, protect teeth, and address aesthetic problems.
Tooth preservation
Natural tooth enamel is susceptible to wear, erosion, and damage from acids and tooth decay. Artificial tooth enamel is designed to help repair or supplement natural tooth enamel to protect the tooth and maintain its structure.
Aesthetic improvements
Discoloration, unevenness, or damage to the enamel often affects the appearance of the teeth. Artificial tooth enamel could correct aesthetic defects in tooth enamel, thereby enabling an improved aesthetic appearance of teeth. The brightness of the teeth is also influenced by the condition of the tooth enamel. If the tooth enamel is no longer intact or is thinner because it has worn away, the teeth appear yellower and grayer.
Sensitivity reduction
Sensitive teeth caused by exposed dentin canals or damaged and abraded enamel should be treated with artificial coatings or materials to reduce sensitivity and improve the patient's well-being.
What is artificial enamel made of?
Artificial tooth enamel is made from various materials designed to mimic the structure and function of natural tooth enamel. Some of them are:
Composite materials
Dental composites are mixtures of plastic resins and fine ceramic or glass powders. They can be used for restorations, such as fillings, or to restore worn tooth enamel. Fortunately, these materials can be matched to the natural tooth color. The disadvantage, however, is that they are softer than real tooth enamel and can become discolored over time.
Glass ionomers
Glass ionomers are materials that contain both organic and inorganic components and have a similar composition to natural tooth enamel. They are often used for fillings or restorations and may provide some release of fluoride. However, from an aesthetic point of view, glass ionomers are disadvantageous and should therefore only be used in the area of the lateral teeth.
Tooth enamel substitutes
There are also specialized products called "enamel restorers" that aim to repair or strengthen tooth enamel. These products contain special minerals or compounds that are similar to natural tooth enamel and are intended to help with remineralization. These are often applied to the teeth as part of dental treatments and incorporated into the tooth enamel.
Hydroxyapatite particles
As mentioned, research is also examining particles made of hydroxyapatite, a mineral found in natural tooth enamel. These particles help remineralize and strengthen tooth enamel.
Applications and treatments for artificial enamel
One possible use of artificial tooth enamel is to treat erosion or damage to tooth enamel caused by acid attacks, tooth decay, or wear and tear. This involves using special coatings or materials to supplement or reinforce damaged tooth enamel. Such restorations help preserve the structure of the tooth and reduce sensitivity.
In addition, artificial tooth enamel is also used for aesthetic improvement. It serves to make the teeth brighter, more even, or more aesthetically pleasing. This can be done by applying thin layers or special materials to conceal imperfections or discoloration in the enamel and achieve an improved appearance.
Controversially discussed: hydroxyapatite as a replacement for fluoride toothpastes?
Is hydroxyapatite an adequate alternative to fluoride? We'll try to get to the heart of this controversy here in just a few words.
Recently, research into tooth enamel remineralization has increasingly focused on the promising active ingredient hydroxyapatite, which is viewed as an innovative alternative to toothpastes containing fluoride. Various studies have shown that hydroxyapatite can remineralize tooth enamel by forming a protective layer and attaching itself to the exposed tooth necks. Although dental care products containing hydroxyapatite do not contain fluoride in some cases, research suggests that they strengthen and repair tooth enamel. These findings are currently being further researched and supported by studies, and this is precisely where the debate about the effectiveness of hydroxyapatite and ensuring adequate caries protection arises.
Fluoride is recognized as a proven caries-preventing agent and is recommended by many dentists and experts. This is simply because the caries-preventing effect of fluoride has been proven to promote remineralization and inhibit cavity-causing bacteria, with an emphasis on proven.
Combining both seems to be the right way. Use a toothpaste in the morning that optimally protects your teeth from caries attacks and one that rebuilds and regenerates tooth enamel in the evening, i.e., a toothpaste that contains hydroxyapatite.
Hydroxyapatite vs. fluoride: what's the difference?
Hydroxyapatite and fluoride are two different substances with different mechanisms of action when it comes to dental health.
Fluoride works primarily by remineralizing tooth enamel and increasing its resistance to acid attacks. It supports remineralization by helping to form minerals such as fluorapatite and hydroxyapatite in tooth enamel. These minerals strengthen teeth and make them more resistant to tooth decay.
Hydroxyapatite also has remineralizing properties. It attaches to exposed teeth and forms a protective layer to strengthen and protect tooth enamel. This layer helps smooth the surface and fill any holes or imperfections in the enamel, resulting in improved hardness and durability.
The difference, however, is that in addition to its remineralizing function, fluoride also has a caries-preventing effect by inhibiting the activity of caries-causing bacteria and reducing the production of acids that can attack tooth enamel.
Although hydroxyapatite strengthens and protects tooth enamel, its mechanism of action and its anti-cavity properties are not the same as those of fluoride. In many cases, the combination of fluoride and other active ingredients, such as hydroxyapatite, in dental care products is recommended to promote holistic dental health and effectively combat tooth decay.
And it is precisely this smart combination that MINT offers with the Classic line as the basis for your daily dental care routine. The Classic Duo “MINT Daily Essentials” consists of the toothpaste with fluoride for morning use and the toothpaste without fluoride with hydroxyapatite for the evening routine. The teeth receive ideal protection from everyday stress during the day and are strengthened by the hydroxyapatite during the night in a regenerative phase.

Toothpaste with artificial enamel
The MINT toothpaste without fluoride works with the innovative active ingredient hydroxyapatite, just like all other MINT toothpastes. The focus here is clearly on the regenerative effect, which is why we recommend toothpaste without fluoride for your evening routine. The high cleaning performance with the MINT-usual, very low RDA value of 39 guarantees a clean and noticeably smooth tooth feeling after every brushing. The tooth enamel is not attacked in any way; on the contrary, the hydroxyapatite protects the teeth and develops its regenerative effect while you sleep.
This toothpaste is particularly helpful if you have pain-sensitive teeth. The hydroxyapatite it contains is in high doses and is therefore able to close the pain-sensitive dentin tubules.

Do toothpastes with artificial enamel not contain fluoride?
Toothpastes containing artificial enamel may contain fluoride, although not all such formulations necessarily contain this mineral. The reason for this often lies in the specific functionality and objectives of these toothpastes.
Some toothpastes that are designed with a focus on repairing or restoring tooth enamel may focus more on other ingredients such as hydroxyapatite, calcium phosphates, or other remineralizing substances that aim to strengthen or regenerate tooth enamel.
Fluoride is known to be an effective tooth decay prevention ingredient because it helps harden tooth enamel and prevent tooth decay. However, there is research and development focused on other materials and substances that have a similar or alternative effect on remineralizing or strengthening tooth enamel.
The choice of toothpaste always depends on individual needs. People who are at increased risk of tooth decay or for whom the use of fluoride is recommended should use a toothpaste containing fluoride to help prevent tooth decay.
However, if you consciously want to avoid fluoride, you don't need to worry: the use of hydroxyapatite is sufficient, but care must be taken to ensure a correspondingly high concentration.
