Liquid tooth enamel:
Can you really do without it?

Have you ever thought about what your teeth go through every day? Every day they are exposed to acids, wear and bacteria.
Can you afford to go without a modern solution like liquid enamel?

The advantages of liquid enamel at a glance:

  • Protective film: Liquid enamel forms an invisible protective layer that wraps around your teeth like a second skin.
  • Smooth and shiny: Liquid enamel ensures mirror-smooth tooth surfaces that not only look pleasantly smooth, but also give you a radiantly healthy smile.
  • Repair: Small defects, early caries, cracks and rough spots are effectively repaired.
  • Whitening: Optical reflection effects provide a natural whitening of the teeth.
  • Protection for sensitive tooth necks: Liquid enamel protects sensitive tooth necks and noticeably reduces reactions to hot, cold or sweet foods

"According to clinical studies, liquid enamel in the form of medical hydroxyapatite has been proven to support the repair of enamel defects. Thanks to its microfine structure, hydroxyapatite can fill the fine microcracks, pores and irregularities in the enamel surface, resulting in a noticeable smoothing and strengthening of the enamel. It has also been proven that hydroxyapatite helps to reduce tooth sensitivity by closing open dentin canals.

The apatite minerals act as a biomimetic replacement for lost enamel particles and accumulate specifically in damaged areas. This reparative effect not only supports the long-term protection against caries, but also ensures an optical brightening of the tooth surface through improved light reflection."

Liquid enamel

Rejuvenation for teeth

Enamel forms the visible outer layer of our teeth. It is the hardest and most mineral-rich tissue in our body and consists mainly of apatite crystals. Abrasion during chewing and, above all, acids attack and erode the enamel surfaces of the teeth on a daily basis. Caries occurs with increased acid attack.

Tooth enamel is unable to regenerate itself apart from remineralisation by saliva, which can be supported by fluoride.

Care measures such as regular tooth brushing are therefore essential for dental health.

Liquid enamel is a type of gel made from the finest, medically pure apatite crystals, which are added to modern dental care products (ApaCare toothpaste, ApaCare Oralactin toothpaste, ApaCare polishing paste, ApaCare repair tooth repair paste and ApaCare Oralactin mouthwash).

They can also be used to close the pores of sensitive tooth necks quickly and permanently.

The most effective is liquid enamel in the form of so-called repair pastes or varnishes (ApaCare Repair or ApaCare Dental varnish), which are applied after brushing or using a dental tray. Fluoride jellies are thus increasingly being replaced.

enamel is thus regenerated and simultaneously whitened by optical reflection effects.

What is liquid enamel?

Tooth enamel is the hardest substance in the human body. It interacts with its environment, saliva and diet throughout its life.

Sweet, carbohydrate-rich and acidic foods dissolve the enamel surface, while the natural saliva minerals build up the enamel again and again. This natural build-up can be supported by fluorides.

ApaCare In addition to fluoride, dental care products also contain liquid enamel, known as medical hydroxyapatite. This binds directly to the tooth surface with each ApaCare application. The liquid enamel fuses with the tooth surface, hardens it, smoothes it, makes it shiny, coats it with a protective layer and repels pathogenic bacterial plaque and discolouration.

FAQ's

ApaCare toothpaste combines liquid enamel with fluoride in a unique preventive formulation. The liquid enamel forms a shiny white, particularly smooth protective layer on the tooth surface, which is strengthened by the fluoride effect and builds up the tooth in the long term.

Liquid enamel refers to micro-fine apatite crystals, the basic material of our teeth. All ApaCare dental care products contain these enamel crystals, which adhere to the tooth surface like a magnet. Liquid enamel forms a shiny white, very smooth protective layer on the tooth surface and builds up the tooth in the long term. The ApaCare protective layer also has an effect on the inside of the tooth: the tooth surface becomes denser and therefore more resistant. Pores or early caries can be reduced and even chalky teeth can be hardened.

Fluoride from the toothpaste reacts with the natural calcium in the saliva on the tooth surface to form an invisible remineralisation (calcium fluoride) layer. From this layer, the calcium enters the tooth and remineralises it. Tooth minerals that are dissolved out of the tooth every day by acids or wear and tear during chewing can thus be stored again and bond with the tooth. Unfortunately, the calcium fluoride layer is only stable for a short time and is broken down again during chewing. This means that the toothpaste you use every day is a very good carrier of fluoride, especially as you brush for longer than you rinse, for example, giving the fluoride time to react.

Fluorid ist eng verwandt zum Chlorid, unserem lebenswichtigen Speisesalz. Beides sind Salze, kommen natürlich vor und haben nichts mit Fluor- oder Chlorgas zu tun. Beide sind für den Organismus sehr wichtig, Fluorid auch für die Knochenbildung. Für beide gibt es sinnvolle Mengenbegrenzungen und innerhalb derer mit großer Toleranz keinerlei Hinweise auf toxische Effekte für Erwachsene und auch nicht für Kinder.

This is exactly what ApaCare does by cleverly stabilising the hydroxyapatite. Fluoride and hydroxyapatite reinforce each other in their remineralising effect. In addition, hydroxyapatite, which chemically consists mainly of calcium, is another source of calcium, which is particularly important in cases of dry mouth with low saliva flow and therefore low salivary calcium.

ApaCare toothpaste has a mild freshness and tastes good. With 1,450ppm fluoride, it is suitable for all age groups.
Toddlers up to 3 years brush twice a day with a lentil-sized amount of toothpaste. Children from 3 to 6 years use a pea-sized amount twice a day and from 6 years use ApaCare toothpaste twice a day with a normal length of toothpaste.

All ApaCare products do not contain aggressive soaps and wetting agents and are therefore particularly gentle and kind to the gums and sensitive oral mucosa. This means that intolerances such as blistering or detachment of the superficial mucous membrane layer can be reliably avoided.

Titanium dioxide was (and still is) widely used as a whitening agent in toothpastes, cosmetics and food. Titanium dioxide (E171) has been banned for foodstuffs throughout the EU since mid-2022 as a result of the nanodiscussion, but is still permitted in cosmetics such as toothpaste. All ApaCare products can easily do without titanium dioxide, as the liquid tooth enamel contains a brilliant natural whitening agent.

400 toothpastes tested: every second one fails

Only a few tubes have sufficient ingredients and active substances

Tübingen, 03/2019 - If the toothpaste delivers what it promises, it comes out on top in the test by consumer magazine Öko-Test. However, only 116 out of 400 toothpastes that have now been analysed by Öko-Test in terms of their ingredients and effectiveness achieve this. The unpleasant result: many pastes contain no or too little fluoride, which is why the products do not offer optimum caries protection. But there are exceptions.

Good dental care prevents dental problems such as tooth decay, periodontal disease or even tooth loss and is probably the most important element of healthy oral hygiene. This requires a good toothpaste full of active ingredients - and there are far fewer of these than you might think when looking at the crowded drugstore shelves. The independent consumer magazine Öko-Test has now published that only 119 out of 400 toothpastes tested by Öko-Test for ingredients and active substances were rated 'very good' and only 27 were rated 'good'. Many toothpastes do not deliver what they promise on the tube.

The biggest shortcoming of the 200 or so products that failed the test is the lack of fluoride content. Fluoride has been proven to prevent tooth decay and should therefore be included in good toothpastes. For example, dental guidelines recommend a fluoride content of 1000 to 1500 ppm (grams per kilogramme) for adult toothpaste, whereby brushing with fluoride-containing toothpaste should be carried out at least twice a day[1].

Best caries prophylaxis with a combination of active ingredients in the tube

The combination of fluoride and hydroxyapatite, an artificial tooth enamel that has only recently become available in toothpastes, has an even stronger preventative effect against tooth decay[2]. Like fluoride, hydroxyapatite also has a remineralising effect and thus protects the hard tooth substance, which consists of a large number of minerals and crystals. During remineralisation, fluoride and hydroxyapatite are deposited in the smallest cracks and defects in the enamel and the underlying dentin. The teeth become stronger and more resistant, tooth sensitivity is noticeably reduced and the teeth feel smooth and clean. The most important thing: remineralisation also has the effect of significantly reducing caries infestation. Caries bacteria find less of a foothold on the tooth surface, where they can colonise: "We have been researching artificial tooth enamel, such as the crystalline mineral hydroxyapatite, as a tooth-protecting substance for many years. Hydroxyapatite is 95 per cent structurally identical to real tooth enamel and has only recently become available in combination with the proven fluoride in a single toothpaste. The two substances have an additive effect. In combination, this results in a double remineralisation effect and therefore double caries protection," explains dentist and dental entrepreneur Prof. Dr Rainer Hahn from Tübingen.

Very good rating for hydroxyapatite and fluoride

So it's no wonder that Öko-Test gave the ApaCare® toothpaste developed by the dentist a 'very good' rating in its 03/2019 issue. ApaCare® contains 1450 ppm sodium fluoride and hydroxyapatite in a patented combination of active ingredients. It is currently the only toothpaste that combines both ingredients.

Liquid enamel – protection and repair for healthy teeth

Tooth enamel is the hardest substance in the human body. However, it can also be attacked by acidic foods, improper brushing techniques, or teeth grinding. Once damaged, the enamel cannot repair itself. This is where liquid enamel comes in. Modern dental care products containing medical-grade hydroxyapatite, the main component of tooth enamel, can help repair and protect the tooth surface.

What is liquid enamel?

Liquid enamel is not enamel in the traditional sense, but a special form of hydroxyapatite with an ultra-fine, liquid consistency. This substance corresponds to natural tooth enamel in its chemical structure and is therefore particularly well absorbed by the tooth. In dental care products such as toothpastes, gels, or mouthwashes, liquid enamel can be applied to the tooth surface, where it fills microscopic damage and smooths the enamel.

How does liquid enamel work?

The ultrafine hydroxyapatite particles are deposited directly on the tooth surface during brushing. There, they act like a repair layer that:

  • Closes microcracks and smooths unevenness
  • Repels acid attacks and protects the tooth from erosion
  • Whitens teeth by making the surface shine
  • Soothes sensitive tooth necks by closing exposed dentin tubules

This not only strengthens the enamel, but the entire tooth surface feels noticeably smoother and healthier.

Is liquid enamel an alternative to fluoride?

A frequently asked question: Do I still need fluoride if I use toothpaste with liquid enamel?

The answer: Both active ingredients have their advantages – and together they are particularly effective. Fluoride makes tooth enamel more acid-resistant, while hydroxyapatite (liquid enamel) visibly repairs and smoothes the enamel. Products like ApaCare Remineralizing Toothpaste combine both active ingredients for maximum protection.

Who is liquid enamel suitable for?

Dental care with liquid enamel is ideal for:

  • People with sensitive teeth
  • Children and adolescents during the tooth eruption phase
  • People at increased risk of tooth decay
  • Patients with exposed tooth necks
  • Those with braces, crowns, or implants

The gentle effect makes hydroxyapatite particularly well-tolerated – even for pregnant women and children.

What are the benefits of liquid enamel in everyday life?

Compared to conventional toothpastes, liquid enamel offers many advantages:

  • Natural whitening thanks to smoother tooth surfaces
  • Less deposits and plaque thanks to reduced adhesion to smooth teeth
  • Long-lasting feeling of freshness thanks to healthy oral flora
  • Visible and noticeable smoothness of the tooth surface
  • Reduced sensitivity to hot and cold stimuli

Which products contain liquid enamel?

ApaCare dental and oral care products contain medical-grade hydroxyapatite in a particularly fine form. These include:

All products are coordinated and ideal for daily care.

How long does it take for liquid tooth enamel to works?

Many people ask themselves: When will I see the first results?

After just a few applications, teeth feel smoother and are less sensitive. After 2–3 weeks of daily use, visible improvements to the tooth surface and a noticeable strengthening of the enamel are possible.

Is liquid enamel safe?

Yes. Hydroxyapatite is a natural component of our teeth and bones. The synthetic version used in dental care products is highly pure and well tolerated. ApaCare products are also:

  • Vegan
  • Free from microplastics, titanium dioxide, and parabens
  • Recommended and scientifically tested by dentists

Conclusion: Liquid enamel as intelligent protection

Liquid enamel with medical-grade hydroxyapatite is a modern, effective, and gentle way to repair weakened enamel and provide long-term protection for teeth. It helps with sensitivity, supports natural tooth whitening, and is suitable for children and adults alike. Ideal as part of your daily dental care with ApaCare products.
