Dental hygienists play a key role in preventing tooth wear

A survey among Norwegian dental hygienists shows strong awareness of erosive tooth wear and highlights the need for clear guidelines and early prevention.

Erosive tooth wear is the gradual loss of tooth substance caused by acids from food, drinks or other sources. It is becoming an increasingly common oral health challenge, particularly among young adults. In a new study, researchers investigated how Norwegian dental hygienists identify, record and manage erosive tooth wear in patients aged 15–30 years. The study was based on responses from 266 dental hygienists working in both public and private dental services across Norway.

What did the researchers find out?

Almost all respondents reported that they record erosive tooth wear in patient records. Most identified sports drinks, energy drinks and soft drinks as the main risk factors. The preventive measures used most often were dietary counselling and recommendations for fluoride rinses or fluoride tablets.

“The survey shows that dental hygienists have a strong focus on prevention and patient education. At the same time, many of them are asking for more guidance and support when it comes to diagnosis and management of erosive tooth wear,” says Aida Mulic, senior researcher at NIOM and co-author of the study. Amela Tulek from NIOM has also been a part of this study.

The survey also showed broad agreement that erosive tooth wear is a significant oral health issue and that preventive efforts should start early.

At the same time, many dental hygienists reported challenges related to diagnosis, monitoring and prevention. A large majority expressed a desire for more knowledge about diagnostic and treatment methods, and more than nine out of ten supported the development of national guidelines.

What are the key results?

The study suggests that Norwegian dental hygienists have substantial knowledge of erosive tooth wear and are actively engaged in prevention and patient education.

However, the findings also point to opportunities for strengthening clinical practice through improved tools, training and national recommendations. Early identification of risk factors and preventive measures may help reduce the progression of tooth wear and preserve oral health in young adults.
