I know that X-rays aren't healthy for us, but is there any extra risks for young children? My almost 3y just went to the dentist and as suspected has a few cavitiys. I feel horrible. 1 is between his front teeth and he'll have to get a shot and the dentist said possibly sedated<img alt="" class="inlineimg" src="/img/vbsmilies/smilies/gloomy.gif" style="border:0px solid;" title="Gloomy">: He will have to have 2 x-rays to check for more cavitys. He mentioned night nursing as a cause, I didn't tell him we are still doing it. I really hope thats not the cause. Thanks for any info.
