Crown on Two Front Teeth

Really, no of this dental work ought to be coming loose. I understand that you are concerned that the one tooth is very short-it can be a factor. There is no good reason to "bridge" these teeth to anything else.

You've done well with the photos you've enclosed. The main problem has to do with the fact that the front part of your bite does not come together very well, AND that the two top front teeth are out of alignment.

 

Very careful analysis of exactly how you slide or bite on your front teeth is necessary. You may need some bonding on the canine teeth (top and/or bottom ones). You need more even "disclusion" so that all of the sliding or biting forces aren't all on these two teeth. In some situations it means veneering more teeth to even out the bite or sometimes braces, orthodontics or Invisalign to make your bite slide better.

 

One other thought- I know you want to be able to chew well on your front teeth. I would think about it this way: you ought to be able to eat some things well, but I would always be careful of biting really crunchy or really hard foods with these teeth. They've been through a lot and really can tolerate more damage.

Best wishes-I bet your dentist will get everything back in great shape for you. Thanks, Dr. Scott Greenhalgh, DDS

As long as there is about 2 millimeters of tooth showing a crown should be successful.  It probably needs to be built up with a post and core restoration first.

The other element to consider for long term success is the force exerted on the crowns due to function (chewing and biting) and stresses from clenching and grinding your teeth.  It is very important that the bite be adjusted properly to minimize stresses placed on the crowns, and if you clench and/or grind your teeth you may need to wear a nightguard or other type of oral appliance to control damaging forces.

 

As long as a sufficient amount of tooth stuctre is still left above the gumline, you should be able to do two single crowns with a post and core in the tooth that had the root canal.
