I managed to break another tooth this afternoon while eating pita bread at lunch.  This makes the 3rd or 4th tooth I have broken and if I keep up the pace I will soon have more broken teeth than intact ones.  Fortunately, the break was completely above the gum line and therefore one I can live with provided I have my dentist grind off the sharp edges on the remainder of the tooth.  Eventually, I will need a crown but for now, I will just leave it the way it is.  The reason I break so many teeth is because I grind them together while sleeping.  Time to locate the mouthguard I am supposed to wear at night to prevent such outcomes.
