I bought a drink and sandwich at Mc Don. and bit down on a piece of ice which contained an arrow head shaped piece of plastic in it from their ice machine. The plastic tore through the stiches I had in my mouth from the bone graph surgery I had 6 weeks ago to prepare my jaw for a dental implant. It lodged in my jaw bone through the opening and dislodged the bone graph pieces I had implanted. My dentist said I have to have a cat scan in 2 weeks to see if the bone harvest and graph has to be redone when the swelling goes down and the remainding bone particals heal back again. Mc Don. called me today to talk about a cash settlement because they have to sign their new insurance policy and they may not want to put in the claim which will increase their insurance cost. I need legal advise.
