This type of bite🍼🍼 can be developed in young children due to prolonged thumb sucking/pacifier 👶🏼(could also be the result of genetics). Sucking for babies is a way to find comfort and soothe themselves. Pediatric dentist Mary Hayes says that "a child in the 2-4 range should start to develop coping skills beyond thumb sucking, such as language development." Hayes says these coping skills are needed to replace the need for a child to suck on his/her finger. "Sucking puts pressure on the sides of the upper jaw and the soft tissue on the roof of the mouth. The upper jaw can narrow, causing the teeth to not meet properly from the top to the bottom." This can be fixed by ortho treatment, like in this picture, but it can also cause speech problems that needs to be corrected with therapy.
If you have babies or toddlers during this stage, try to come up with creative ways to help your child! 💙👶🏼🍼😊
