thumb-sucking in children/ kebiasaan menghisap ibu jari

Babies have natural rooting and sucking reflexes, which can cause them to put their thumbs or fingers into their mouths. Because thumb sucking is soothing to babies, some might eventually develop a habit of thumb sucking when they’re bored, tired or anxious.

Many children stop sucking their thumbs on their own sometime during the toddler years — between ages 2 and 4. Even though a child who’s stopped sucking his or her thumb might revert to the behavior when he or she is stressed or anxious.We used to think that as long as a child stopped sucking by the time they developed their permanent teeth there would be minimal impact on the mouth and jaw, but now research shows that thumb or finger sucking can have an impact even at a younger age — as young as 2 to 4 years old.

The thumb-sucking puts pressure on the sides of the upper jaw and the soft tissue on the roof of the mouth. As a result, the upper jaw can narrow, causing the teeth to not meet properly from the top to the bottom. Although this can be fixed with braces, it can also cause speech problems.

Another efffect because of thumb-sucking is a “thumb hole” in the roof of the mouth, which comes from sucking, can cause the teeth in the back of the mouth to take on the brunt of chewing. This causes an imbalance across the teeth and affects the structure of the mouth and jaw as they are growing with the child.

Bayi mempunyai refleks untuk menghisap, sehingga membuat anak secara tidak sengaja memasukkan ibu jari ke dalam mulutnya. Karena memasukkan ibu jari ke dalam mulut dapat menenangkan bayi.

Beberapa anak akan berhenti menghisap ibu jarinya sendiri ketika berumur sekitar 2-4 tahun. Meskipun anak dapat kembali menghisap ibu jari ketika sedang stress atau tegang. Banyak yang berpendapat apabila anak berhenti menghisap ibu jari pada saat gigi permanen tumbuh maka tidak ada efeknya pada pertumbuhan rahang, tetapi penelitian telah membuktikan bahwa kebiasaan menghisap ibu jari pada umur 2-4 tahun dapat berakibat buruk terhadap pertumbuhan rahang.

Kebiasaan ibu jari akan menyebabkan tekanan pada ibu jari pada langit-langit mulut, sehingga mengakibatkan lengkung gigi rahang atas menjadi sempit, gigi-geligi atas tidak kontak dengan gigi-geligi atas, masalah dalam berbicara. Hal-hal di atas dapat dirawat dengan perawatan ortodontik.

Efek negatif lain yang disebabkan oleh kebiasaan menghisap ibu jari adalah lubang pada langi-langit mulut, sehingga kesulitan untuk mengunyah dan ketidakseimbangan pertumbuhan struktur rahang atas dan bawah.
