The issue of mouth protection is debated. The World Health Organization WHO advocates this in places where it is difficult to keep distance, as well as several of the world's countries. But the Public Health Agency believes, among other things, that such a recommendation could create a false sense of security and lead to people stopping following the advice that already exists. 

"The issue is not dead," said CEO Johan Carlsson this week. In a few weeks, the authority is expected to announce whether they will, after all, introduce recommendations on oral protection.

"A piece of the puzzle"

But several companies are now taking their own initiatives on mouth protection. The train operator MTRX has no requirement, but offers mouth protection on the train between Stockholm and Gothenburg. 

- The public health authority has been clear that you should stay at home if you are ill or have symptoms and book a place, but they have also been clear that they can not control all industries in detail. We choose to add another piece of the puzzle that can create a safe journey, says the train company's CEO Mats Johannesson. 

The reactions from the train passengers vary, but according to him, more and more people receive the mouth guards. The debate about Sweden's view of mouth protection may have played a role. 

A company that has gone a step further is the technology giant Apple, which demands that both employees and customers wear mouth guards in the flagship store in Täby center.

"Hard to talk"

For Alexandra Frank, it was the first time she wore a mouth guard. 

- It was very unusual, it felt very strange. It was difficult to talk, and it was difficult to have contact with those who would help one, she says. 

The Disney store in Solna has also introduced oral protection requirements for staff and customers. The coffee retailer Nespresso demands that all employees wear mouth guards and this week the hotel chain Nordic Choice also announced that they are introducing requirements for mouth guards for all employees in the Nordic and Baltic countries.
