It doesn't help me either that a dentist very recently told me it was my fault my teeth are like this too! It's diet and hygiene related he said. I said yes i have some sugar, i make the occasional cakes for people and I told him that no matter how well I look after them it makes no difference and sometimes it feels like the more I brush and floss, the more they have issues. That's while I was bawling my eyes out at having to have yet another tooth pulled because it just could not be saved while knowing I still have at least one more that is likely to be beyond saving. I then went on to hyperventilate during the procedure and got so light headed felt close to passing out. That makes a total of 4 teeth pulled for decay and another 4 pulled when I was younger to make room to get braces for overcrowding.
I can deal with losing wisdom teeth (of which 3 decayed ones were) but any others are just heartbreaking for me to lose.
