Why does immunity decrease during teething?

Teething does not directly cause a decrease in immunity. The process of teething itself does not affect the immune system. However, infants and toddlers going through teething may experience discomfort, sleep deprivation, and changes in appetite, which can indirectly impact their overall health and well-being. These factors can make them more susceptible to illnesses, leading to the misconception that teething weakens the immune system.

It's essential to ensure proper hygiene during teething to prevent gum infections that could potentially contribute to a weakened immune response. Maintaining a nutritious diet and promoting adequate rest can also help support a healthy immune system in infants and toddlers during this phase.
