Hi Birgitta,
thank you for taking the time to review! 🤗
It's so typical if you find that they don't stick even though you've dried your teeth beforehand!
It might also be good to avoid brushing right before, and you can try to secure the strip properly with your finger, press and shape it around each tooth. Try to press a little extra on the edges so that it really gets a chance to stick ❤
It could also be that your teeth are very smooth or that saliva production is high, so it can be a bit tricky to get the strips to stick 🙈
