1} Learning Process

Grinding of teeth may be a new learning process which makes them explore what their new teeth feels and sounds like. As a child, at a young age having teeth is a new feeling. Children outgrow this habit very soon and grinding of teeth disappears.


2} Response to growth and development

Baby grinding teeth may just be a natural phenomenon. Grinding can also be due to response to development and only time can help overcome it. Once the permanent teeth start erupting, children automatically stop grinding their teeth.

3} Stress and anxiety

Often, grinding of the teeth can be due to factors like stress and anxiety. Stress induces the excess production of adrenaline hormones. Children suffering from bruxism have high concentration of the adrenaline hormone in their urine. Children dealing with stress and anxiety often resort to bruxism or grinding of teeth.

4} Imperfect positioning of teeth

Improper alignment of upper and lower teeth when jaws remain closed can promote teeth grinding. Hence, when your baby is sleeping he loses control of his mouth and begins grinding his teeth.

5} Poor oral hygiene

Poor oral hygiene is one of the most common causes of teeth grinding. Gum inflammation can cause grinding of teeth especially in children who do not brush their teeth regularly and maintain poor oral hygiene.
