Q. Hi, after my childhood of abusing my teeth and now im 24 the backs end of my mouth either side are mostly full of fillings, my oral health on a whole is pretty good with flossing etc, i have had a couple of teeth break around the edges that have been filled and with dental fees so expensive im putting off getting a proper long term solution sorted. approximatley 5 teeth towards the back req some form of work, my dentist has mentioned crowns and root canals however i hear root canals are painfull?? I also seem to find my mouth is quite acidic. are there any oral issues that can cause this? What kind of things should i be searching for as i will want to get these sorted sooner rather then later. many thanks
