Q宝宝牙长齐了,还流口水是怎么回事?宝宝1岁半了,牙也长了20颗,很久不流口水了,但最近又开始流了,是怎么回事呢?A宝宝出现你叙述的情况,考虑如下:通常宝宝在1岁半时乳牙还没有出齐。你的宝宝虽然已经出了20颗牙,但是往往在第二乳磨牙萌出时,由于牙龈肿胀充血,且出牙对牙龈感觉神经的机械刺激的缘故,造成唾液腺反射性地增加分泌。加上此时小儿的吞咽功能还不健全,口腔深度不够,不会依靠吞咽来调节口腔内的唾液量,所以口水多了就会往外流出。
Q baby teeth together, but also drooling is how the baby? 1 year and a half, teeth also grow 20, long time no drooling, but recently began to flow, what happened? A baby appeared You describe the situation, consider the following: Usually baby at 1 year and a half when the primary teeth have not yet been together. Although your baby has 20 teeth out, it often causes the salivary glands to reflexively increase secretion as the second molars erupt due to swelling and congestion of the gums and mechanical stimulation of the gingival sensory nerves due to teething. Coupled with this time the child’s swallowing function is not perfect, the depth of the mouth is not enough, will not rely on swallowing to adjust the amount of saliva in the mouth, so more saliva will flow out.
