Unfortunatly one of my back teeth started hurting on Friday. I thought something was caught between the teeth and flossed repeatedly. The pain continued. Today, after waking up at 3 am, I went first to a dentist who gave me a referral to an endodontist AND an oral surgeon. The endodontist said the tooth had already had a root canal and altho she would do another, the prognosis was not good. So Friday morning I will go to the oral surgeon and have the tooth with a cracked root yanked out. I brought this misery on myself, by eating chocolate covered almonds from Trader Joes. Yes they were covered with dark chocolate.
