Ask the doctor to try the root treatment again. Our son had similar issue and the doctor suggested the same method. I asked her to try twice , no matter the results and it worked, at least it's OK for a year post that treatment我家宝宝由于在婴儿阶段,晚上喂奶后没有清理口腔,造成上排最前面4 颗牙齿龋齿,完全不发育了。1岁半的时候,医生建议带牙套。于是我们就忍着心痛做了全麻手术。想着至少能撑到宝宝换牙。但是不久前宝宝的牙龈长了一个胞,带她去看牙医,说是上次的根管治疗没弄好,现在牙根发炎,没法治疗了,要直接拔掉, 而且要拔两颗,预防旁边的牙被感染坏掉。各位爸爸妈妈们有什么好主意,实在是不想拔,娃太小了。
