Willo's mouthpiece size is recommended based on age, gender as well as and whether your child's permanent molars are present. Our size chart will help you ensure the best fit for your children's mouths. Each size is suitable for each of our customers. As your child grows, you will be able to change their mouthpiece size at any time.
