Babybjörn Synergy Baby Carrier

I purchased a Bjorn Synergy carrier a year ago. I loved using it - until my baby started cutting teeth.  I would carry her facing out, and she would bite on the carrier.  No big deal - until her tooth got caught in one of the little holes in the mesh material.  She screamed in pain and blood was coming from her gums. I had to pry her tiny tooth out of the material.  The whole ordeal was very scary - for a minute I thought she'd lose the tooth she had just cut.  I began using a bib for her to bite whenever I carried her in the Bjorn facing out.  About a month later it happened again - she got her teeth stuck in the material.  More painful screaming, more blood.  It's amazing she still has those teeth.  This could be very easily avoided by using a different material for the top portion of the carrier.
