Good and Bad
The good news: Despite a low occasional ache in a back tooth, my dentist says I have no cavities! This is the first time in my life a dentist has EVER told me that! Woo!
The bad news: Something is causing an ache in my back tooth. It could be stress, it could be the chin strap I wear while I sleep (for the CPAP machine) making me clench or grind... The dentist ground down the high points of the tooth a bit just in case. I do have an 11-year-old filling back there, but they say it's in good shape.
Still! No cavities! Let's eat sugar and celebrate!
