question: Well i might aswell be honest,I'm now 19 and i think the last time i properly cleaned my teeth i was about 9 or 10 years old but By some miracle i still have all my natural teeth i.e. no false ones or any fell out.. And the only thing i do is mouthwash every 2 days,Silly i know..Any advice as to how much damage i have actually done? I still go to my dentist twice a year and they have yet to actually do anything with my teeth,all they keep doing is this spray type thing and the usual poke around..
