Which professional teeth whitening course do you offer?
X-treme Smile offers a professional teeth whitening course for beginners as well as experienced professionals who want to learn how to carry out cosmetic teeth whitening treatments in a knowledgeable and responsible way.
Why choose X-treme Smile?
What sets our training apart is our dental background. X-treme Smile is the only specialised training provider in the Netherlands in the field of professional teeth whitening where dental knowledge and practical experience form the foundation of the course.
Within our team, different professional backgrounds come together, including:
- dental assisting;
- dental hygiene;
- dental technology;
- many years of practical experience with professional teeth whitening;
- extensive knowledge of whitening products, active ingredients and equipment.
This means that you do not only learn how to carry out a treatment, but also why each step is important.
Applying whitening gel and positioning a lamp can be learned from a protocol. Working professionally requires more. You need to understand what you are seeing, why results differ between clients, which choices you can make during a treatment and when it may be better not to treat.
What do you learn during the course?
During the professional teeth whitening course, we cover:
- different types of tooth discolouration;
- professional intake and client selection;
- realistic expectations and achievable results;
- situations in which treatment may not be advisable;
- different whitening products and active ingredients;
- Pink and Booster and when to use each product;
- treatment protocols and the correct sequence;
- treatment rounds and application times;
- correct use and positioning of the whitening lamp;
- preparation, hygiene and protection;
- sensitivity and common practical situations;
- product storage and shelf life;
- aftercare and client advice;
- relevant rules and regulations surrounding professional teeth whitening.
More than just a standard protocol
No two clients are the same. That is why we want you to understand how to deal professionally with different situations in practice.
Why does one client achieve a lighter result more quickly than another? Which types of discolouration usually respond well and which are less predictable? When do you choose Pink and when Booster? What can you do when the result is limited? How important is the positioning of the whitening lamp? And when should a client first be referred to a dentist?
This is where our dental background and many years of practical experience make a real difference.
Support after your training
Our guidance does not stop when you receive your certificate.
If you have completed your training with X-treme Smile and later encounter a situation during your work that you are unsure about, you can continue to contact us with professional questions.
You are therefore not limited to a course manual or information found online, but can rely on a team with dental knowledge and practical experience.
Suitable for beginners and experienced professionals
You do not need a dental qualification to take our course. The training is structured so that beginners can start from the basics.
If you have already completed a teeth whitening course elsewhere but feel that you are still missing certain knowledge, our course can also help you deepen your understanding and learn our complete professional working method.
After successful completion, you will receive your X-treme Smile certificate.
Working outside the Netherlands
Our training is also available to international students.
Please note that laws, professional requirements and regulations differ from country to country. The fact that you have successfully completed an X-treme Smile course does not automatically mean that you are legally permitted to offer the treatment independently in every country.
Each student is responsible for checking the laws and professional requirements that apply in the country where they intend to work. This may include rules relating to professional qualifications, the products used, hydrogen peroxide limits, licences, insurance or who is legally permitted to carry out the treatment.
X-treme Smile teaches you the knowledge, skills, protocols, hygiene and professional working methods needed for the treatment. Local legal requirements must always be checked separately by the student.
At X-treme Smile, you do not simply learn how to perform a whitening treatment. You learn from a training provider with a dental background, so you understand what you are doing, why you are doing it and how to deal professionally with the situations you may encounter in practice.
