COUGEX® Cavity-Repair Gel targets cavities at the source.
Formulated with FDA-recognized 10% Nano-Hydroxyapatite (NH-10) and supported by extensive global clinical literature, its biomimetic composition provides a 97% match to natural tooth enamel.
Driven by magnet-like ionic forces, the gel penetrates deep into micro-cracks and cavity holes to precisely eliminate cavity-causing bacteria and trigger rapid mineral recrystallization.
It permanently seals cavity holes, eliminating the problem of conventional fillings falling out, while helping rebuild weakened enamel and draw deeply embedded pigments out of microscopic enamel pores.
The result is significant pain relief and visible tooth repair in as little as 1 hour.
Biomimetic nano-hydroxyapatite designed to closely match the mineral structure of natural tooth enamel.
Penetrates deep into micro-cracks and cavity holes for precision-targeted treatment.
Designed to permanently seal cavity holes without drilling or traditional light-curing fillings.
Supports rapid mineral recrystallization, significant pain relief and visible repair in as little as one hour.
Tooth decay (dental caries) is a progressive oral disease caused primarily by acid-producing bacteria and the loss of essential tooth minerals.
From around the age of 30, tooth enamel gradually becomes thinner and saliva production begins to decline. Once this protective enamel layer becomes thin, exposed tooth roots can decay up to 3 times faster, while microscopic, invisible cavities may begin breaking down the tooth from the inside out.
If you experience severe, persistent pain, the tooth nerve may already be dying — leaving painful root canal treatment, expensive surgical procedures (>€3,000), or tooth extraction as the only remaining options.
Bacterial acids attack essential tooth minerals and weaken the natural enamel structure.
As we age, the tooth's natural protective enamel layer can gradually become thinner.
Microscopic damage can develop within the tooth structure before it becomes visible on the outside.
Clinical studies have confirmed that untreated tooth decay and deep dental infections may not only increase systemic inflammation, but can also significantly increase the risk of serious cardiovascular conditions such as stroke and heart disease.
COUGEX® Cavity-Repair Natural Enamel Filling Gel is formulated with 10% Nano-Hydroxyapatite (NH-10), designed to target cavity holes, micro-cracks, weakened enamel, sensitivity and deep-seated pigments while supporting mineral recrystallization.
Precision application directly onto affected tooth areas.
Designed to seal exposed dentin tubules and reduce discomfort.
Supports enamel remineralization and a smoother, brighter appearance.
Specially developed to target cavities and enamel erosion, COUGEX® Cavity-Repair Gel delivers visible results in as little as 1 hour.
It quickly relieves pain and sensitivity while actively remineralizing weakened enamel to fill cavities, seal micro-cracks and restore a strong, healthy-looking smile.
Designed to deliver rapid, visible improvement in targeted damaged areas.
Supports active remineralization to rebuild weakened tooth surfaces.
Targets microscopic defects and cavity holes for precision enamel restoration.
Helps restore a cleaner, smoother and naturally brighter-looking smile with continued use.
A four-step system designed to relieve discomfort, rebuild damaged enamel, restore natural brightness, and rebalance the oral environment.
NH-10 provides rapid, targeted relief for severe tooth pain and swollen gums through a dual-action formula.
Powered by ionic charges, its 10% nano-particles act like microscopic plugs, sealing exposed dentinal tubules within seconds to physically block acid, temperature, and pain signals from reaching the nerve.
At the same time, active soothing agents work like a cellular “fire extinguisher,” helping neutralize bacterial inflammation and reduce vascular congestion to rapidly shrink swollen gum tissue for fast, long-lasting comfort.
Driven by ionic charge attraction, the high-concentration NH-10 nano-particles penetrate deep into tooth-surface defects and actively lock into mineral gaps.
This process helps fill microscopic cracks and rebuild damaged tooth structures at the source.
Unlike synthetic resins, no blue-light curing is required. Instead, the material fuses directly with the natural tooth matrix and recrystallizes to true bone-like density, permanently integrating into a stronger, more rigid tooth structure.
NH-10 fills tiny pits and scratches on the tooth surface while drawing dark pigments out of deep enamel pores.
By raising the oral pH to 6, it actively reduces demineralization and dramatically increases your teeth’s resistance to acids and cavities.
Because natural enamel is essentially a transparent crystal structure, NH-10 increases enamel thickness to restore the youthful, radiant white appearance of your natural teeth.
It creates a mirror-smooth surface that naturally reflects light and effectively prevents future coffee and tea stains from adhering.
Most products rely on harsh mint to temporarily mask bad breath, only for the odor to return later. NH-10 takes a completely different approach: it physically removes the source.
Bad breath is caused by sulfur-producing bacteria that decay inside invisible tooth micro-holes and exposed root areas.
NH-10 acts like a molecular vacuum, magnetically binding odor-causing bacteria and flushing them completely away.
At the same time, it floods and seals microscopic pits and cracks across the tooth surface, eliminating hidden traps where food debris and plaque can ferment.
A highly concentrated, medical-grade Nano-Hydroxyapatite system designed to closely mirror the natural mineral structure of teeth.
Driven by ionic attraction, these ultra-fine nano-particles seek out microscopic cracks and cavity holes and settle directly into them.
It helps strengthen enamel, reduce sensitivity and restore the tooth surface to a smoother, stronger condition.
A highly purified plant-derived active ingredient designed to rapidly address acute dental inflammation, redness and painful swelling.
It acts as a powerful soothing agent, helps loosen calcified tartar deposits and supports the neutralization of deep-seated oral infections.
An advanced clinical synergy designed to break down aggressive oral biofilms.
It works like a molecular vacuum, surrounding cavity-causing and sulfur-producing bacteria so they can be more easily rinsed away.
It helps remove early tartar deposits and prevents minerals from hardening into stubborn buildup.
A cell-regenerative compound designed to support the tooth-supporting bone and alveolar tissue.
It stimulates cellular metabolism to help increase bone density while reinforcing the structural framework around the jawbone and tooth roots.
An advanced synergy of bioavailable Vitamins C, E and B5 designed to support a healthy oral microbiome.
It helps restore the oral micro-ecosystem, strengthen periodontal fibers and reinforce support around weakened tooth roots to dramatically reduce tooth mobility.

Customer photos and experiences with COUGEX®
“I accidentally chipped a small piece off my tooth while eating crab, and from then on, it seemed to get weaker day by day. Every time I ate hot, cold, or acidic foods, I experienced a sharp, terrible sensitivity.
I even considered getting a crown, but the cost was astronomically high, and I was afraid of having even more of my natural tooth filed down. Then I discovered COUGEX® Natural Enamel Gel.
The pain relief was immediate! Not only did it completely fill in and repair the chipped corner, but it also seamlessly removed the chalky white spots. Now that awful sensitivity when eating cold shrimp is 100% gone!
On top of that, my friends have noticed that my teeth have been looking whiter and brighter lately. An extremely affordable and cost-effective solution!”
“My unbearable toothache made it impossible for me to chew on that side, and just the thought of the dentist’s drill made me shudder. So I started applying COUGEX® Cavity Repair Gel directly to the affected area—the immediate pain relief was incredible!
What surprised me most was that just one hour after applying it, I was able to eat again without discomfort. Within a few days, the gel had completely filled and smoothed over the cavity. The color of the filling matches my natural teeth perfectly—you can’t see any difference at all!
It’s been 2 months now, and nothing has worn away or fallen out. I can eat normally again.”
“I was supposed to attend a wedding, but my front teeth looked yellow, had fine hairline cracks, and even coffee stains around the edges. I bought COUGEX® DenPerm Natural Enamel Gel as an emergency solution, and the results were absolutely amazing!
Just a few hours after applying it, I could already see that my teeth looked noticeably whiter and brighter. After using it for a few days, not only had the fine cracks smoothed out, but the transparent appearance around the edges had disappeared as well!”
“Because of my diabetes, I struggled for a long time with loose front teeth and embarrassing bad breath. It was awful. Even though I brushed my teeth thoroughly every day, I couldn’t save my discolored teeth.
I decided to try COUGEX® Cavity Repair Gel, and in just 5 short days, the results were incredible! My bad breath completely disappeared. My loose teeth now feel remarkably firm—I can even bite directly into an apple again!”

Everything you need to know about COUGEX® Cavity-Repair Gel, its application and targeted enamel-care system.
COUGEX® is based on a 10% biomimetic enamel infusion system featuring the NH-10 formula. It is designed to support targeted enamel care through:
Targeted Filling: Designed to reach and fill microscopic cracks and affected areas of the tooth surface.
Biomimetic Remineralization: Supports mineral replenishment by working with the remaining natural tooth structure without resin or light-curing.
Sensitivity Support: Helps coat exposed dentin and microscopic tooth pores to support greater everyday comfort.
Natural enamel does not regenerate in the same way as living tissue, but mineral-based oral-care ingredients can support remineralization of weakened enamel surfaces. COUGEX® is designed to act as a mineral-rich coating that supports the existing tooth structure and helps promote a smoother enamel surface.
Results can vary depending on the condition of the tooth and how consistently the product is used. Some users may notice changes in comfort or surface feel relatively quickly, while continued daily use is intended to provide ongoing mineral contact with the targeted area.
For best results, use COUGEX® consistently according to the product directions.
Individual experiences vary. COUGEX® is designed to coat exposed tooth surfaces and complement normal oral hygiene, which may help support greater comfort and a cleaner, fresher-feeling mouth with regular use.
Follow this simple 3-step application routine:
COUGEX® is formulated without peroxide-based bleaching agents or harsh restorative acids. It is designed as a gentle, targeted addition to a regular oral-care routine.
If you experience persistent discomfort or irritation, discontinue use and consult a dental professional.
