My third tooth from inside, lower jaw, was slowly broken and the finally gone when I was around 14 years, and I am 30 now living with that gap, mostly avoided heavy chewing on that side. Unfortunately, on the other side of the lower jaw, the 3rd tooth from inside, had to do tooth fill 4 years before. Some six months back tooth filling came out, but I am still hesitant to go to dentist for re-filling, because last time itself, he checked that gap and told me that he need to remove the side teeth, and then he will plant 3 tooth which really scared me. Otherwise my teeth will get gaps in between itseems, but so far I dint see it happen. Should I really do that 3 tooth planting on loosing those original teeth, or I can still continue living with it?
