Can I start working professionally after completing a training course?

Yes. After successfully completing many of our courses, you can start working professionally, provided you stay within the scope of the treatment and comply with the legislation that applies where you work.

Our courses have been reviewed against the Dutch BIG Act and relevant Dutch legislation. We teach the professional knowledge, practical skills, hygiene procedures and treatment boundaries needed to carry out the treatments responsibly.

Teeth whitening within the European Union

For teeth whitening, important product rules apply throughout the European Union.

Under EU cosmetics legislation:

≤0.1% hydrogen peroxide, present or released → cosmetic category and not restricted by EU cosmetics law to dental practitioners

>0.1% up to 6% hydrogen peroxide, present or released → dental practitioner involvement is legally required

Products containing or releasing more than 0.1% and up to 6% hydrogen peroxide may only be sold to dental practitioners. The first use of each treatment cycle must be carried out by a dental practitioner or under their direct supervision where an equivalent level of safety is ensured. These products may not be used on anyone under 18.

The percentage refers not only to hydrogen peroxide added directly to a product, but also to hydrogen peroxide released by other ingredients or mixtures.

In the Netherlands, the NVWA explicitly confirms that beauty professionals and whitening salons may use products that contain or release no more than 0.1% hydrogen peroxide.

Individual EU countries may have additional professional requirements, so local legislation should always be checked.

Tooth Gems

After completing a Tooth Gem course, you can start with the non-invasive cosmetic application of Tooth Gems to intact tooth enamel, provided this is permitted under the legislation of the country where you work.

Our training remains within the cosmetic scope. It does not teach you to drill or grind teeth, remove tooth tissue or make dental diagnoses.

Cosmetic teeth polishing

Our Cosmetic Teeth Polishing course is limited to superficial cosmetic polishing of intact teeth and the reduction of superficial staining.

It does not include:

• calculus removal;
• subgingival cleaning;
• treatment of gum disease;
• grinding or removal of tooth tissue;
• treatment or correction of dental restorations;
• dental diagnosis.

For this treatment, you must be properly trained and competent. If you have not received appropriate training and do not have sufficient knowledge and practical competence, you should not perform the treatment independently.

Working outside the Netherlands

We train students from many different countries. It is unfortunately not possible for us to research and guarantee the professional legislation of every country in which a student may later work.

What we can do is teach you the skills, treatment protocols, hygiene, product knowledge and professional boundaries required to perform the treatment responsibly.

If you work outside the Netherlands, you are responsible for checking whether your country requires additional qualifications, registrations, licences or other conditions.

For English-speaking students who work in the Netherlands, the same Dutch conditions apply as to our Dutch-speaking students. The language of the course does not change the legislation.

In short

After an X-treme Smile course, you can often start working professionally relatively quickly:

Teeth whitening → EU rules distinguish between ≤0.1% and >0.1%–6% H₂O₂ present or released
Tooth Gems → non-invasive cosmetic application to intact enamel
Cosmetic teeth polishing → superficial polishing only and only when properly trained and competent

Our courses teach you the professional skills required for these treatments. If you work outside the Netherlands, always check the additional national rules that may apply.
