Q. Hi there,i have had to have my front tooth filled twice in the space of a couple of months as it kept going slack then fell out,i got quite a shock when it fell out at the amount of tooth that had been taken away..i changed my dentist as i wasnt happy with this happening all the time and when he refilled it he had to do more drilling due to some decay and said if it falls out again i would need to get a crown! I am worried about this and definately dont want to loose my front tooth, i would also like to know some reasons as to why it keeps coming loose so i can prevent this from happening? thanyou very much.,
