① Now is the time to start dental care.
- ⓐ You should recognize that a baby needs dental care. In most cases, you assume that the milk teeth will be replaced by permanent tooth and become less careful. But the cavity and loss in the milk teeth may change your baby’s mouth shape while bad teeth may hinder nutritional intake. Thus, appropriate care for each phase of development is required.
- ⓑ Once the teeth come out, babies may fret as the gum will hurt or itch. Let them wear a teether, which is effective for gum massage. Note that it must be sterilized before use.
② The order of milk teeth development Teeth growth varies greatly in each baby. Thus, even if the milk teeth come out before a baby becomes 1 year old, you don’t need to worry. On the contrary, if that’s not the case and you’re still concerned about it, you may want to consult with a dentist.
③ Milk teeth care for cavity prevention Once the teeth come out, brush them clean with a baby tooth brush. Baby food leaves remnants in the mouth. Have your baby wash his mouth with water after meals.
