Many parents ask me: Can baby’s milk teeth become cavities too? The answer is yes. Babies often drink milk and like to eat sweets, and most of them have not yet developed good brushing habits, therefore, the milk teeth are easily decayed. However, many parents don’t pay attention to baby’s “milk tooth decay”, thinking that it will be fine after the permanent teeth are replaced, in fact, it is not. Remind all parents to protect baby’s milk teeth, it is very important for baby. If the decay of baby teeth leads to pulpitis or periodontitis, it will affect the eruption of permanent teeth in the future and cause the permanent teeth to be weak and easily damaged. If the baby teeth are lost too early or too late, the permanent teeth will be misplaced or not grow out, which will make the teeth misaligned and bite incorrectly, and affect the chewing of food or the beauty of teeth. Tooth decay, also known as tooth decay, worm tooth, tooth decay, is a disease caused by a combination of factors, mainly bacterial infection, which destroys the hard tissues of teeth. If it is convenient, we suggest you bring your child to the hospital for further examination and standardize the treatment after detailed examination of the child’s condition. In addition, it is necessary to pay attention to oral hygiene, brush teeth after meals, and reduce the consumption of sweet food, in addition to the standard treatment in the hospital.
