What should I do if my baby has a seam after changing his teeth? Parents should pay attention to the baby's oral problems in child-rearing from the moment when the baby sprouts the first deciduous tooth, but it is inevitable that the baby will encounter such problems when changing teeth. Many parents are consulting.
When a child is about 6 years old, deciduous teeth will fall off one after another and be gradually replaced by permanent teeth. The permanent dentition will not take shape until 12 years old. From 6 years old to 12 years old, there are both deciduous teeth and permanent teeth in the mouth, which is called mixed dentition period, which is characterized by irregular tooth arrangement, also known as ugly duckling period.
At this stage, some parents find that there is a middle seam between their children's two newly-developed upper incisors, and some even show a figure of eight, so they are very worried. They are afraid that their children's front teeth will grow bad and ask the doctor to correct them. In fact, in most cases, there is no need for treatment.
Because the eruption of permanent teeth has a certain time sequence, the eruption time of maxillary central incisors (commonly known as upper incisors) is 69 years old, and the eruption time of lateral incisors (teeth next to incisors) is 7 1 1 year.
The middle seam appeared in the early stage of upper incisor eruption, and some of it was caused by the lateral incisor embryo pressing the root of upper incisor during eruption. As long as the lateral incisor next to it erupts, the gap will naturally disappear. Some gaps are caused by the deviation of permanent incisors to the labial side and the increase of dental arch width when they erupt. However, when primary teeth alternate with permanent teeth, the permanent teeth are generally larger than primary teeth, and the central seam of front teeth can just make up for this difference.
Moreover, deciduous molars fall off, the first permanent molars tend to move forward, and the central incisors can be closed gradually. Therefore, children's central incisors are only temporary and generally adjust themselves in the process of growth and development without correction.
Of course, the middle seam of children's front teeth may also be caused by special reasons such as supernumerary teeth in the middle or low attachment of the upper lip ligament. After the dentist's examination, it can be solved by pulling out the supernumerary teeth or trimming the upper lip band. If the baby's teeth are all changed and there are gaps in the front teeth, it is necessary to go to a regular medical institution for corrective treatment. There are many reasons that may lead to a large gap between children's front teeth, depending on the doctor's examination results.
Baby's tooth filling process 1, tooth cavity preparation: tooth cavity making is the stage of tooth drilling and the first step of tooth filling process. Do a good job of decayed teeth before filling teeth. A cavity consists of a cavity wall, a cavity edge and a cavity corner. Doctors need to do these things in the process of drilling holes:
① Remove the diseased tissue, otherwise it will cause secondary caries;
② Protect dental pulp and healthy tooth tissue;
(3) Establish a good retention form and resistance form to avoid secondary caries caused by fracture, falling off and loosening of the filling body.
2, disinfection: this step is very important, if disinfection is not thorough, it is easy for bacteria to continue to grow in the tooth cavity, affecting the child's toothache again in the future. Most of the infections in the teeth were removed after the cavities were completed. In order to better eliminate the residual infection in the disinfection process, further cavity disinfection is needed. The drugs used to disinfect dental cavities should have strong bactericidal power, no damage to dental pulp, analgesic and soothing effects, no discoloration of teeth and no influence on the performance of filling materials. Disinfection is the second step in the process of filling teeth, which is particularly important. It directly affects the pain of patients after filling their teeth.
3. Filling the filling material: Filling is to fill the filling material into the prepared cavity. Isolate saliva, disinfect the tooth cavity, fill the tooth cavity with filling materials, carve the shape, and pay attention to remove the part that is too high above the occlusal surface to avoid iatrogenic occlusal trauma. The filling material should be non-toxic, wear-resistant, compressive, unchanged in volume after filling, close to the cavity, not corroded or dissolved by saliva, simple in operation and beautiful in color.
4. Grinding or polishing: the tooth surface needs to be smooth, but the filling material is not satisfactory after solidification. The purpose of polishing or polishing is to smooth the tiny unevenness on the surface of the filler.
5. Remove residue: After filling with filling materials, the dentist will polish the surface of the teeth and clean up the residue attached around the teeth.
