I had a root canal done a year ago and I never went back to get the crown.
The temporary filling lasted about a month then it started to wear away.
Its almost completely gone now and i have a huge hole in my tooth.
Its not a pretty sight.
I`m sure there is more decay in my tooth that will have to be taken out since it has been so long.
I would strongly suggest that you don`t leave a temporary filling in since its not designed to last more than a month.
It is temporary and will wear away and leave the tooth open for more damage.
and remember- only floss the ones you wanna keep ;)
