Markus,

You are correct, small minor salivary and mucous glands are producing their products. The overlying skin (mucous membrane etc.) grows much faster and can grow over the tiny openings of these and result in tiny blisters as the saliva products are produced. This should become less prevalent as healing continues.

Any blisters that result in pain or ulceration that do not heal within 2 weeks should be mentioned to your doctors.

Cheers,

Mike
