I took out my €1500 savings and got a dental implant, it wasn't a front tooth but in my smile line and I couldn't laugh or anything without covering my mouth, it really affected my confidence and I got a great deal! Have to wait 6 months before I can get the crown screwed in but I'm so glad I got it before I just learned to accept it. Your teeth have to last you your whole life.
Other than that I'd split it between an amazing little holiday with DD and a long weekend away with DP and try squeeze another weekend away with friends! Experiences and memories are always the better option in my opinion. I definitely wouldn't spend it on extra expensive Christmas presents for DD as selfish as that may sound, toys end up discarded etc but maybe tickets to pantos, theme park, other things she would enjoy!
I'd definitely consider botox but that's something you'd really have to keep up if even on a yearly basis.
I'd love to fill my make up bag with the absolute best but the mojo problem with that is going back to your old stuff when it wastes!
Or I'd get myself a little run around car and loads of driving lessons as I've found I've taken fifty steps back and I'm now a very nervous driver.
Pay off any little loans knocking around, sounds boring but you'd be thankful in the long run.
I've WAY over spent and over thought this
my vote is your tooth and make amazing memories!
