问:几年前我镶上了全口假牙,一开始效果还不错,可今年我发现假牙有所松动。医生说是由于营养缺乏引起的,我不明白,假牙松动与营养不足有关吗?
Q: I put a full denture a few years ago. The effect was not so bad at the beginning. But this year I found the denture loosened. Doctors say it is due to lack of nutrition, I do not understand, dentures loose and nutrition related to it?
