My 2 front caps and posts came out, can I super glue them back?

There is always a reason a crown and post comes out.  It may be a sign of decay or deterioration of the roots or teeth under the crown?  It may be a lack of retention or too small of a post size... etc.  Please seek out a dentist for a consultation and Xrays to evaluate the teeth.  

Hi:Absolutely not.  It’s best to go to a dentist to cement the post and crowns properly with a dental cement.  Best,Dr. Maddahi

Donot use super glue on your teeth. First you need to know why the post and crown came out. Do you have decay under it ?  Reach out to your dentist and let them evaluate the teeth.  If you can't get to the dentist right away , buy dental glue form super market in dental section and use that Til you get a chances to visit your dentist. Good luck. 

You should not use super glue on your teeth as it can cause severe damage. Find a dentist in your area to recement them if possible.

Please don't use any type of glue on your teeth as it can definitely damage your teeth. Visit a dentist in your area to help you with evaluation of the teeth as soon as you can! All the best.

I would not as I have seen some real messes and may impair the dentists ability to properly cement/bond your dentistry.  Just go to a dentist ASAP and have them evaluate "Why" they came out....otherwise whatever you do will fail quickly at home.You can use some denture adhesive or temporary cement bought in the toothbrush isle at most grocery type stores.
