“My unbearable toothaches kept me from chewing on that side, and the mere thought of the dentist's drill sent shivers down my spine. So I began applying 𝑲𝒆𝒚𝒆𝒔𝒔® 𝑫𝒆𝒏𝒑𝒆𝒓𝒎 𝑭𝒐𝒈𝒔𝒛𝒖𝒗𝒂𝒔𝒐𝒅á𝒔𝒕 𝑱𝒂𝒗í𝒕ó 𝑻𝒆𝒓𝒎é𝒔𝒛𝒆𝒕𝒆𝒔 𝑭𝒐𝒈𝒛𝒐𝒎á𝒏𝒄𝒕ö𝒎ö 𝑮é𝒍 directly to the affected area. The immediate pain relief was incredible! What surprised me most was that just one hour after applying it, I could already eat without any discomfort. In just a few days, the gel had completely filled and smoothed the cavity. The color of the filling blends perfectly with my natural teeth. It's been 2 months now, and it hasn't worn away or come loose at all. I can eat normally again.” - Anna Nagy — Magyarország — Budapest

“I accidentally chipped a piece of my tooth while eating crab, and it felt more and more fragile afterward. Whenever I ate something hot, cold, or acidic, I felt terrible, sharp sensitivity. I considered getting a crown, but the cost was astronomical. That's when I discovered 𝑲𝒆𝒚𝒆𝒔𝒔® 𝑫𝒆𝒏𝒑𝒆𝒓𝒎 𝑭𝒐𝒈𝒔𝒛𝒖𝒗𝒂𝒔𝒐𝒅á𝒔𝒕 𝑱𝒂𝒗í𝒕ó 𝑻𝒆𝒓𝒎é𝒔𝒛𝒆𝒕𝒆𝒔 𝑭𝒐𝒈𝒛𝒐𝒎á𝒏𝒄𝒕ö𝒎ö 𝑮é𝒍. The pain relief was immediate! Not only did it completely fill and repair the chipped corner, but it also made the white spots disappear. Now that uncomfortable sensitivity is 100% gone!” - Luca Kovács — Magyarország — Debrecen

Tooth decay is a progressive oral disease primarily caused by acid-producing bacteria and the loss of essential tooth minerals. After age 30, tooth enamel gradually thins and saliva production decreases. When this protective enamel becomes thin, exposed tooth roots deteriorate 3 times faster. By the time sharp pain begins, the tooth nerve is often already affected, leaving painful root canals, expensive surgical procedures (over 967,830 Ft), or extraction as the only options. Furthermore, clinical research has confirmed that untreated cavities worsen systemic inflammation and increase the risk of cardiovascular disease.

Naturally repair damaged enamel and whiten teeth in 5 days

Specially formulated to combat cavities and enamel erosion, 𝑲𝒆𝒚𝒆𝒔𝒔® 𝑫𝒆𝒏𝒑𝒆𝒓𝒎 𝑭𝒐𝒈𝒔𝒛𝒖𝒗𝒂𝒔𝒐𝒅á𝒔𝒕 𝑱𝒂𝒗í𝒕ó 𝑻𝒆𝒓𝒎é𝒔𝒛𝒆𝒕𝒆𝒔 𝑭𝒐𝒈𝒛𝒐𝒎á𝒏𝒄𝒕ö𝒎ö 𝑮é𝒍 offers 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 smile.

How does DenPerm Cavity Repair Gel work?

Step 1: Immediate toothache relief and a quick return to chewing

NH-10 provides fast, targeted relief for severe toothaches and swollen gums. Guided by ionic charges, its 10% nanoparticles act like microscopic plugs, instantly sealing exposed dentinal tubules to physically block acids, temperature changes, and pain signals transmitted to the nerve. At the same time, soothing agents neutralize bacterial inflammation and reduce vascular congestion to quickly reduce swelling in gum tissue.

Step 2: Rebuild damaged teeth: Remineralize enamel and seal micro-cracks

Driven by ionic attraction, highly concentrated NH-10 nanoparticles penetrate deep into surface defects in the tooth to fill micro-cracks and rebuild tooth structure at its source. Unlike synthetic resins, no blue-light curing is required: the gel fuses directly with your natural tooth matrix, recrystallizing with real bone density to integrate permanently.

Step 3: Lifelong enamel strengthening: Restore your teeth's brightest natural shade

NH-10 provides deep internal whitening by micro-filling fine surface scratches and extracting dark pigments embedded in enamel's micropores. By raising oral pH to 6, it actively reduces decalcification and strengthens your teeth's resistance to acid attacks. As natural enamel regains its thickness, it restores your teeth's original translucency and whiteness while preventing future coffee and tea stains from adhering.

Step 4: The ultimate bad-breath neutralizer: Balance the oral environment

Most products temporarily mask bad breath with strong mint. NH-10 eliminates the root cause: sulfur-producing bacteria nestled in cavities and roots. NH-10 acts like a molecular vacuum, capturing these odor-causing bacteria so they can be rinsed away. At the same time, it seals every micro-crack, removing places where food debris ferments.

🧬 A key formula that remineralizes natural teeth at the source

🛡️ NH-10 (10% Biomimetic Enamel Infusion)

A highly concentrated, medical-grade nano-hydroxyapatite system that closely mimics natural tooth structure. It bonds within micro-cracks and cavities to strengthen enamel, reduce sensitivity, and rebuild tooth density from within.

🌱 Dipotassium Glycyrrhizinate (Soothing Anti-Swelling Agent)

A purified botanical active ingredient that rapidly eliminates dental inflammation, redness, and painful swelling. It helps soften calcified tartar and creates a clean foundation for oral recovery.

🧪 IPMP & Zinc Complex (Molecular Anti-Tartar Shield)

A clinical combination designed to break down oral biofilms. It captures cavity-causing bacteria so they can be rinsed away easily, dissolving early tartar to ensure fresh breath all day.

⚡ Allantoin (Tooth-Bone Structure Strengthening Matrix)

A cell-regenerating compound designed to strengthen alveolar bone and tooth-supporting tissues. It stimulates cellular metabolism to strengthen the anchoring of tooth roots.

🧬 Enriched Vitamin Formula (Oral Ecosystem Stabilizing Complex)

A synergistic blend of bioavailable vitamins (C, E, and B5) formulated to restore the oral micro-ecosystem, strengthen periodontal fibers, and firm up loose teeth.

Rebuilding tooth enamel requires uninterrupted mineral crystallization. Follow this routine every evening before bed:

1. Clean & Prepare: Brush your teeth thoroughly and floss to remove plaque and debris. Rinse with water.
2. Targeted Application: Remove the syringe cap. Place the precision applicator tip directly on the targeted cavities, micro-cracks, or sensitive areas.
3. Apply & Leave in Place: Gently press the plunger to deposit a small dab of gel on the affected tooth structure. Let the product naturally cover the area without wiping it away.
4. Overnight Action (The Key Step): Do NOT rinse, eat, or drink after application. Leave the gel on overnight (6 to 8 hours) for optimal crystallization.

Why at night? Saliva production decreases during sleep. This reduced dilution allows the 10% Nano-Hydroxyapatite (NH-10) particles to stay in place deep within micro-cracks.
