I crown my four front teeths (a pair on each side) almost 15 years ago. 10 years ago it chips in front in the middle, but i went to a dentist to do a bonding in the edge to mend it. Today, both pair of teeth receded and the gap reappear. My right hand side pair of teeth obviously seems stick together, look unnatural, when people speak to me, i feel that they keep staring at my teeth and know it is a crown. i can see laughter in thier eyes. And the gap in the middle making me uneasy and very self conscious. I don’t know what to do, do i need to redo the crown or put some layers of veneer or bonding to touch up the worn teeth. please advice more in detail and specific because after this i will go to a dentist and have my teeth checked, but i like to know before hand what should be my good alternatif and not making more wrong steps cause it already causing headache and making me withdrawn from people, i try not to open my mouth or smile in order not to show my teeth!
