I am going to give my two cents on
tongue rings, sorry in advance. Having very little to do with pregnancy, I say take it out. I got mine done when I was 18. Prior to that I had great teeth, never had a cavity or anything. I took it out when I was like 24 or 25 and ever since then my teeth have taken a rather rapid turn for the worst. I am now 32 and so far I am missing two teeth, luckily they are back teeth, that I had to have pulled because there was no saving them.
