Briefly:
I've got a crown that is 28 years in (got knocked in the face and the tooth 'died'. It's got a metal spike /pin in it)
2 front ones were crowned about 20 years ago .They are 'thick' opaque and because the cement is grey, it's visible at the gumline.
I need another one done, it's very discoloured and started to chip bit by bit. But if I have that one done, the colour difference will be really noticeable (and because they've changed and improved in the last few years)
So..........
Is it possible to replace 3 old crowns and a new one?
Would I need to go private for this?
I'm going to go to a new dentist (well the one I used to go to years back, but I'll be starting as a 'new' patient due to the time lapse)
What sort of price (roughly) I know it varies.
How horrendous will I feel after?
Apart from jaw-ache 
.
