When does a child's teeth change?

Each of our children will go through a stage of tooth replacement. During the stage of tooth replacement, we must grasp it well and never let children eat irritating foods, which may affect our dental health and cause great damage to our own tooth enamel. At the same time, our children must develop a good habit of brushing their teeth every morning and evening. Here we will popularize the time and precautions for children's tooth replacement.

"At the age of seven or eight, you need to change your teeth." This is the rule of children's tooth replacement time that people often say. Children's tooth replacement refers to the time when the deciduous teeth fall off by themselves and the new permanent teeth erupt, that is, the time when the deciduous and permanent teeth exchange shifts. The handover between deciduous and permanent teeth is not in a short period of time such as a few months or a year. The 20 deciduous teeth and permanent teeth do not take over at the same time, and this time is relatively long, and the handover task can only be completed in about 6 to 7 years. When does the tooth replacement time start? This varies from person to person and has a certain relationship with the child's gender, nutrition, and development. For example: From current clinical observations, girls change their teeth earlier than boys, and children with good nutrition and early development change their teeth earlier than those with malnutrition and delayed development. However, there are certain rules for the replacement time and order of deciduous and permanent teeth.

Generally speaking, when most children are six years old, the first permanent molar (i.e. the sixth-year molar) begins to erupt behind the second deciduous molar. Soon or at the same time, the deciduous lower front teeth and the permanent lower front teeth begin to be replaced, followed by the lower deciduous lateral incisors and the permanent lateral incisors, and then the upper incisors begin to be replaced. This replacement continues until about 12 years old, or later until about 14 years old. According to survey data, the normal time when children begin to replace their teeth is: 6 to 7 years old for deciduous central incisors, 7 to 8 years old for deciduous lateral incisors, 9 to 12 years old for deciduous canines, 9 to 11 years old for first deciduous molars, and 10 to 12 years old for second deciduous molars. Therefore, the period of tooth replacement is a critical period for a person. If you want to have white, neat and healthy teeth throughout your life, you must pay attention to the hygiene of the dental cavity during the period of tooth replacement and keep a good tooth replacement.

Our mothers must pay special attention to the above-mentioned time and precautions for children's tooth replacement. During the tooth replacement stage, we must try to supplement our children with some calcium. Calcium can help our growing teeth become stronger. Everyone should pay special attention to it!
