I'm back to having a gap in my teeth
I don't understand why you have a gap in your teeth again?
I'm in the mood of having it back.
I guess if it makes you feel good then it is okay. You should always take care of your teeth. If it will become problematic you should go back to having it fixed.
I keep a good dentist.
If you use a good dentist then you should know that you need to take care of your teeth. You only get one pair of your own, and you shouldn't destroy them!
