Children are prone to caries during childhood is related to the following reasons: 1. It is conducive to the growth and pathogenesis of bacteria, and increase the chance of caries; 5.Children eat less fibrous food, which is not conducive to the cleaning of tooth surface; 6.The form of milk teeth is conducive to the residue of food and the reproduction of bacteria, which leads to the occurrence of dental caries. Caries has grown into Caries is divided into shallow caries, medium caries and deep caries according to the severity of the condition, shallow caries mostly hurts the enamel or bone; medium caries can form a cavity, and it will be painful when encountering cold, hot, acid, sweet and other stimuli; deep caries reaches the pulp cavity, and it is often very sensitive to temperature and chemical stimulation. Now the insect tooth of Peng Peng is already in the degree of medium caries! Tooth care action: In the name of teeth and sweets Cakes, cookies, candies, these delicious foods are irresistible to weak-willed babies, but they are very easy to adhere and stick to the surface of the teeth, providing a good environment for the occurrence of dental caries, so these foods can only be used occasionally. It is better to let children eat more rough and fibrous foods, such as vegetables, fruits and meat, which are not only nutritious, but also can clean the tooth surface by chewing and rubbing, reduce the residue and make it unable to ferment. Tooth decay treatment N: The decay of milk teeth does not need to be treated, and it will become good teeth naturally after the permanent teeth are replaced. The tooth decay not only hurts the tooth itself, but also the tooth pulp and alveolar bone, and then the permanent teeth will be affected too. Y: Since too much cane sugar will induce the formation of tooth decay, why not find some other sugar substitutes instead of cane sugar. Xylitol is a good substitute for sucrose, and the survey shows that it can reduce the incidence of oral cavities by 85 to 90%! Encounter with plaque Plaque can exist on baby’s gums and teeth, and can also appear in the baby’s teeth, it is soft and sticky, not easy to be removed, it is a bacteria-based “ecosystem” that resides on the teeth, even if it is removed manually, it will be re-formed in about 1 to 6 hours.

Care of the oral cavity N: found in the mouth of the newborn baby “teeth” like material, the mother rushed to take a cloth to wipe. That is only the epithelial beads commonly known as “horse teeth”, and the baby’s oral mucosa is very thin and tender, so it is easy to be scratched and cause infection. Y: Breastfeeding should be done as much as possible, which will help the baby to suck to help the normal development of the jaw and face. When artificial feeding should choose a reasonably designed pacifier, pay attention to timely cleaning, so as not to cause unnecessary damage to the mouth therefore.
