In our work, we often have to communicate with parents about root canal treatment of milk teeth, and now we will explain several common questions. 1.In what cases should root canal treatment be done for milk teeth? Acute and chronic pulpitis of milk teeth; acute and chronic periapical inflammation; etc. Root canal treatment is the best and most effective treatment method. Although the baby tooth is to be replaced, root canal treatment is still required if needed. 2.Does root canal treatment affect permanent teeth (tooth replacement)? Root canal treatment itself will not affect the permanent teeth, if there is any effect, it is the lesion of the baby tooth itself, especially the serious apical lesion of the baby tooth. Root canal treatment can reduce or avoid the negative impact of the lesions on the permanent teeth. Therefore, it is necessary to do it. Don’t blame the “good guys”! 3. Do I need root canal treatment even if my tooth has never hurt before? Yes, it is totally possible! If the caries of the baby tooth develops quickly, sometimes it is very hidden, and the child is not able to express himself clearly, there may be a case that even though there is no symptom, the tooth pulp has been affected and root canal treatment is needed. 4.Will the tooth still hurt after root canal treatment (pulp is removed)? Yes, it will! After root canal treatment, the pulp is removed and the pulpal pain is gone, but periapical pain may still occur. 5.Is root canal treatment for baby teeth painful? Can children bear it? Root canal treatment is still painful for children, fear, pain, long time open mouth, etc. will bring discomfort and pain. Most children can tolerate it. 6.What if the child does not cooperate during root canal treatment? When you encounter a child who does not cooperate with the treatment, the first thing is to do a good job of reassurance and try to make them cooperate. Secondly, treatment under compulsion, which has many risks and cannot be done in place, is no longer advocated. The third is treatment under general anesthesia, which many parents have been able to accept. All teeth are treated at once under general anesthesia. Parents are advised to choose the treatment method at their discretion. 7.How many times can the root canal treatment of milk teeth be completed? Generally, it can be completed in 2 – 3 times, but sometimes it can be completed in one time according to the condition and the child’s cooperation.
