if you do actually have a problem with your teeth, i.e. rotting. Then you should go to the dentist otherside YOU WILL SUFFER LATER ON IN LIFE LIKE I DID. I had to go to a hospital where they drugged me and took out 6 rotten teeth. I woke up feeling stoned and i couldn't walk straight... not a pleasant sight.
'Cos if so, I think it's a no brainer.
