Front tooth part chipped. What can I use to glue it back on? (Photo)

That tooth looks like it has decay.  I would see a dentist and have them take an X-ray.  They will be able to give you a treatment plan to restore it at that visit.  Good luck.  

When you chip a front tooth that is so visible, go see a cosmetic dentist.  The cosmetic dentist just means that they like to make your fillings look good.  They will take an xray to evaluate the hole and make a recommendation.  Hopefully you just need another  filling.  Unfortunately super glue washes out in saliva and it sticks to your lips so you can have a big problem.  Good luck!  

It is never wise to practice dentistry on yourself!  You cannot glue a restoration back in.  The restoration for a reason, likely in your case- decay. You will need an x-ray, and your dentist can remove the decay and place a new restoration on that tooth for you.
