At 9 months old, I noticed that my baby’s upper incisors are slightly blackened, and then gradually become more charcoal-black, with small holes and gaping holes. What’s going on? Does it need to be treated? My baby is almost 2 years old, and the surface of his incisors are yellowing and slowly falling out, and now half of his teeth have fallen out. What is this? Do I need to treat it? As mentioned in the above question, the child’s incisors have small black spots, chunks of loss, yellowing and softening of the teeth, black teeth are the manifestation of dental caries (which is also commonly known as insect teeth, tooth decay). Incisor caries is not timely treatment, will continue to develop to the nerve, will cause tooth pain, if further to the root and around the teeth will cause red gums, pus, swelling of the upper lip and may cause the child fever. In addition, the lower part of the baby teeth is the permanent teeth that will be replaced, if the caries leads to the expansion of the surrounding inflammation may affect the lower part of the permanent teeth, resulting in the eruption of the permanent teeth or the development of abnormalities. Caries in the incisors of children can be caused by the following: Poor feeding and eating habits. Poor feeding and eating habits, such as playing with a bottle for a long time or even falling asleep with a bottle, night feeding after tooth eruption, prolonged breastfeeding or bottle-feeding, snacking before bedtime, or drinking too many sugary drinks, and so on. Bad oral hygiene habits. Many babies’ parents think that their children are too young to brush their teeth, or give up brushing due to the children’s own resistance to brushing. Defects in the development of the teeth. Some babies are more susceptible to dental caries because of congenital enamel underdevelopment, etc., and the speed of development of dental caries is also more rapid than that of normally developing babies. Therefore, in order to avoid the pain of dental caries and to avoid affecting the replacement of teeth, parents are given the following treatment suggestions; in order to avoid the aggravation of the condition of the baby’s teeth and to avoid affecting the replacement of teeth, please go to a professional children’s stomatology department in time for consultation. Thoroughly correct bad feeding and eating habits, avoid snacks before bedtime and do not drink too much sugary drinks. After 10 months, try to practice your child to drink from a cup and avoid using a bottle for a long time. Brush your baby’s teeth carefully to maintain good oral hygiene. Before one year of age, brush your baby’s teeth with warm water using a dampened gauze or finger toothbrush. After one year of age, brush your baby’s teeth with a toothbrush. Add a small amount of toothpaste when your baby can rinse his or her mouth. Until age six, try to have parents help with checkups and help clean teeth thoroughly. Regular pediatric dental checkups every three to six months make it easier to detect problems in time for early treatment.
