Hello!
I just went to the dentist today after 5 years, because bits were falling off one of my teeth ! Anyway - They check it out thinking it'll need a simple filling - but nope - it was decayed inside and fractured - so they had to take all the decay away and put a temporary cover on... next week we get to see what they do to fix it !
They used drills and gave me 2 injections!
So make sure you go regularly for check-ups so you don't have to go through what I'm going through! And make sure you brush your teeth regularly!
