Why Would my Bridge Chip in the Same Place over and over Again?

They are chipping because something has changed - so most likely causes are:

1. They haven't made the same bite as you have before when you chew or grind;

2. You are grinding more because you aren't comfortable with the changes with your bite;

3. Something is faulty with the porcelain (least likely);

4. Some other unforeseen change in your bite??

Hope this helps.

Kathy,

Your bridge is chipping because your lower front teeth are somehow coming into contact with the uppers in a way that is chipping the incisal surface (lower edges).  This can occur  during natural chewing cycles where the lower jaw actually moves side to side as it goes down and comes up.  Or, you could be grinding your teeth at night time unknowingly.  For what ever reason something changed between the old bridge and the new bridge.  I'm guessing that an interference was "unintentionally" built in.  This happens often when teeth are lengthened for cosmetic purposes.  Interferences can cause parafunction (grinding or gritting) and/or touch prematurely during normal function.  Sometimes we can even see a change in phonetics (lisping).

It appears that your occlusion needs to be addressed in this area of recurrent chipping.  The interferences need to be identified and removed.

 

Hope this helps,
