I'm in my early 30s and every time I seem to go to the dentist I need some work doing. Recently part of a tooth snapped off and it had to be crowned. I've also already got a couple root canals and 5 crowns in total. I did drink lots of fizzy drinks in my teens and 20s by generally my diet is good and I've got a healthy bmi etc. I no longer indulge in too much sugar and haven't touched a fizzy drink for a few years. I'm just getting in a real tiz about whether all this dental work will have an impact on my health generally, I've read about links between root canals and cancer and i'm also starting to panic about what happens when these crowns eventually fail - will my teeth start needing to be extracted? AIBU to be this worried about it all??
