Online Tooth Gem Training 2026: Everything You Need to Know Before Starting

Looking to learn tooth gem application but not sure which training course to pick, how much it costs, or how to get started? You're not alone: in 2026, searches for "online tooth gem training" have exploded in France, driven by the hype around tooth gems on TikTok and Instagram. This guide answers all your questions so you can make the right choice and avoid the common pitfalls.

Why train for tooth gem application in 2026?

The tooth gem market is experiencing spectacular growth. In France, demand grew 4x between 2021 and 2025 (source: Google Trends). Behind this buzz lies a very concrete economic reality:

• Low initial investment: between €99 (training only) and €299 (training + complete kit), you can launch your business.
• Fast profitability: with an average application price between €30 and €120 and a material cost of €3 to €8, margins exceed 90%.
• Flexible activity: as a side business to an existing profession (beautician, hairstylist, dental technician) or as a main business under the micro-entrepreneur status.
• No specific state diploma required: in 2026, there is no state-issued diploma for tooth gem application. However, a quality professional training course is essential to practice safely, and a training certificate is required.

What does a professional tooth gem training course include?

A good training course covers both the theoretical foundations and hands-on practice. Here are the essential elements you should find in the program:

The theoretical component

• Hygiene and asepsis: equipment disinfection, wearing gloves, using oral retractors — the basic gestures for working cleanly.
• Contraindications: cavities, ceramic crowns, and devitalized teeth that prevent application.
• Information about the products used
• Application techniques

The application technique (main steps)

Without going into every detail (that's what the training course is for!), here are the four key steps of the application protocol:

1. Etching: preparing the enamel surface to improve primer and composite adhesion.
2. Primer (bonding agent): applying a product that links the enamel to the composite resin.
3. Composite (dental resin): the biocompatible CE-certified material that holds the gem in place on the tooth.
4. UV/LED curing: hardening the primer and/or primer-composite under a specific lamp for a few seconds.

The training walks you through each step in detail with a complete PDF and an instructional video, so you can reproduce the technique with confidence.

The equipment included (or not)

This is a crucial point that sets training courses apart. At Ma Formation Strass, two packages are available:

Important: the training certificate is only issued with the complete package (training + kit), because we can only certify people who have used our products specifically designed for the technique we teach.

What about a practice jaw?

We don't include a practice jaw in our kits. Why? Because we recommend practicing directly on a real person — a friend, acquaintance, or family member. Nothing replaces the experience of a real human mouth: saliva, movement, dealing with a client's apprehension… It's the best way to be fully operational from your very first paid applications. That said, if you still prefer to start on a training aid, practice jaws are available separately.

Online vs in-person training: how to choose?

Online training has one major advantage: you can rewatch the videos as many times as you need and move at your own pace. It's especially well-suited if you're already working and want to train in the evenings or on weekends.

Is tooth gem training eligible for the CPF?

This is the question everyone asks: "Is tooth gem training eligible for the CPF (French Personal Training Account)?"

The answer is clear: no. In 2026, no tooth gem training course is eligible for the CPF. To qualify, a training program must be registered with the RNCP (French National Directory of Professional Certifications) or the RS — which is not the case for any tooth gem training course to date.

⚠️ Warning: some organizations claim to offer a CPF-eligible tooth gem training course. In reality, they enroll students in another certification (typically in beauty or nail care) and deliver the tooth gem training on the side. This is CPF fraud, punishable by law (law no. 2022-1587 of December 19, 2022). The risks: full reimbursement, a ban on running a training organization, and criminal prosecution.

What are the alternatives to finance your training?

• Pay in 4 interest-free installments: at Ma Formation Strass, we set up pay-in-4 interest-free through Alma, starting at €100 in purchases. It's the ideal solution for getting started without a large upfront investment.
• Self-financing: with a kit at €299 and an average application price of €40-€70, your training is paid off in 5-10 applications — typically within your first week of business.

How to choose your training: 5 essential criteria

1. Program content: make sure it covers theory (hygiene, contraindications) AND practice (etching, primer-composite, curing). Be wary of training courses that only include a one- or two-page PDF.
2. Equipment included: a training course with an integrated kit lets you get started immediately. Make sure the products are professional grade (CE-certified composite, quality gems).
3. Post-training support: asking questions after training is normal and essential. Check that the instructor offers follow-up.
4. Reviews from former students: read testimonials and verified reviews. Be wary of training courses with zero client feedback.
5. Value for money: compare the actual content (training content, kit quality, certification) rather than price alone.
