Hi Bryanna! Hope all is well with you. I saw my dentist today who referred me to an endo. The xray show the root canal front tooth has an overfill. He could not tell me whether or not that was causing my symptoms or whether there is still bacteria in there

So when I got home I started googling root canal overfill and some sites say the material they use contain formaldehyde! Now I am really stressed out. How will I know if my root canals have formaldehyde? Are there any alternatives? I've been trying to avoid this chemical never realizing I have been exposing myself to it through root canals... I currently have 3 root canals
