Q. I have recently had a crown replaced on a lower front tooth. As my usual dentist has recently left the practice the new dentist carried out the replacement but felt it was rather unstable and that I should have had been advised to have an implant. She didn’t feel she could embed the post sufficiently due to concern that the root would break. From her comments about it not being a very strong repair I am now not sure it is advisable for me to continue playing the saxophone which is of immense significance to me. I don’t if you can advise me from this information alone but any guidance would be gratefully received.
