Removing crowns on two front teeth

Hi!  I would really appreciate your input...
I have all porcelain crowns on my two front teeth. This summer, I had a
root canal on one of them, and decided to replace both crowns (they
were over 10 years old, and the other was cracked. The dentist replaced
my crowns a few days ago, but they are much lighter than the rest of my
teeth, and I am very unhappy with the shape of them. My surrounding
teeth are as light as I can get them, so I cannot bleach them to match
the front crowns.  My dentist agreed to replace them under the
condition that I signed a paper in case a root canal was needed again
or if a tooth was broken in the process.  I do not have much tooth
structure left.  A post was put into the tooth with the root canal. I
am terrified that the tooth will break when he tries to remove these
crowns.  Can you please tell me the success of removing crowns on teeth
with root canals, and less tooth structure.  I had very bad, protruding
teeth as a child, and really do not want to have to live with these
crowns, but do not want to lose my teeth either.  Thank you so much for
your help.

    Generally I don't attempt to remove crowns per se; I cut them
off--unless I am sure there is no risk of fracture.  Since I can almost
never be sure of this, I rarely try to pop single crowns off.  Takes
only a little more time, and eliminates the risk of fracturing the tooth.

What type of all porcelain crowns are they?
as far as the consent form sounds reasonable he just wants to record
that you understand the risks.
This problem happens often when you only do 2 front teeth. You risk
getting the bunny look. You might want to consider asking him to do the
teeth on either side by placing very thin no prep veneers or a thin
bonding to block out the colour depending on how far off the colour is.
The eye teeth are 1/2-1 shade darker normally so it should blend in.
He may want to entertain this option since there is less risk for you
and less headache for him if you are up to it.

Thank you for your suggestions.
I am not sure what kind of porcelain they are.  I live in a small city
and don't even think that my dentist uses veneers.  I am also hoping to
correct this without touching any of my other teeth.. I guess that I
will take a chance and hopefully get better results with the next
crowns.  I am crossing my fingers that these ones come off without
breaking my teeth.  Thanks again.
Alexander Vasserman DDS - 12 Sep 2006 07:10 GMT
He knows about the veneers and can probably do them.
There are dentists in 3rd world countries doing veneers.

Didn't you have an opportunity to approve the shape and the color
before the crowns were cemented in place?

HI! I did look at them before they were cemented.  However, the dentist
told me that the colour was great.  I told them that I thought that the
crowns were protruding too much, but was told that they were the best
that they could do with my teeth underneath protruding a bit.  My old
crowns, however, did not protrude..  I thought that maybe because they
were a bit different than my other ones, that I just had to get used to
them, and that they didn't stick out as much as I thought.  I was also
VERY nervous, as I have had so much work done to my mouth and was
afraid to complain. I was told by others in the next few days that yes
the colour was way off and it looked like they stuck out quite a bit.
I now wish that I would have spoke up more at the time, but I am too
late...
I do appreciate your comments.  Thank you very much

Hi!  I posted earlier about replacing 2 front crowns.I will be getting
them replaced in a few weeks.   Besides the colour being to light, I
have also explained that these ones are just too big.  They are VERY
bulky on the sides which make them look even more like buck teeth.  The
dentist said that was pretty well the best they could get, but my
crowns before these ones were much better, and they were 10 years old.
Is there anything that you think could be done this time to have them
more aesthetically pleasing?  I am including links to both my before
pictures of the old crowns, and the new ones. Thanks again

The new crowns definitely looks whiter. I am not sure if your small
town dental lab can do custom shade.  Usually the dentist use a shade
guide to choose a color.  But for front teeth where is is very visible,
I send my patient to the dental lab for custom shade.  The lab tech
will match color to your other teeth.  I am not sure if that's possible
at your location.

I can't really comment on the shape because it's hard to judge with the
picture.  However, if the old crowns felt comfortable, the new ones
should also.

There are 2 ways to remove a crown:

1) by tapping it out with force
2) by cutting it out

I agree with Dr. B that cutting it may be better for you in this case.

By the way, your gum around your 2 old crowns looks very red and
inflamed.

Hi!
The sad part is that I did go to someone for custom shading.  They told
me that it was the right color. He said that maybe it was the liner he
used that made them look too white. When I went back to get a new color
for my next crowns, he wanted to use the same shade again and touch it
up once they were done.  I asked him to go a bit darker, and hopefully
they will match my teeth.  This is a very stressful process!  I feel
like I am the only one who cares that they look good!
I see where my gums look inflamed.  They were not always like that, but
have been again since these crowns were put in 3 weeks ago.  I take
very good care of my teeth and do not understand why my gums do that!!

Front teeth are usually hard to match color, but custom shading will
usually do the work.  You probably know this by now.  When the dentist
try in your new crown, before cementing, what you see is what you get.
So if you don't like it, don't let him/her cement it.  The lab can
adjust the color until you like it.

It is the dentist's responsibility to get the crowns to your liking.
You may want to suggest to the dentist to use a new lab.

Regarding the gum, sometimes(not saying this is the case because I need
visual exam) if the margin of the crown is not well made it can:

1) impinge on the gum and thus irritate it
or
2) cause food/plaque to trap near the margin and thus irritate the gum

Thank you.  I have learned my lesson and will not have them cemented
until they are the right color.  I should have refused to have them
cemented last time, but as I said, thought that maybe it was just be
and that I would get used to them.  Thank you for your help.  I
appreciate it.
I will also ask the dentist about the margins.  The gum above my right
tooth feels sensitive and hurts a bit if I bite into anything.  I have
just been avoiding it, and am using a fork for everything!

something is not right about these 2 photos
In the after these are PFM crowns not the most cosmetic to put on the
front teeth, ofcourse we do not know whats underneath.

HI!  The crowns should be solid porcelain, not fused to metal. When I
was first making my appointment with the dentist, he said that I would
be getting PFM crowns, and I was very clear that I wanted all porcelain
crowns. I saw the crowns before they were put into my mouth, and I
didn't notice any metal. At the lab, the person who chose my colour
said something about a porcelain that was approximately 40.00 more a
tooth that would hide the color underneath if it was a bit darker. One
of the front teeth is darker and has had a root canal.  Is there any
way I can tell if these are PFM?? I am getting prepped for new crowns
next week and am very nervous that they will look as artificial as
these ones do!
Thank you very much!

I just checked my insurance claim and it states that the crowns are
Porcelain jacket crowns.  They were 907.00 Canadian each.  Does that
sound like PFM crowns??

what was written on the claim form does not mean anything.
question is when you looked on the inside of the crown was it dark or
white like a tooth??
You can have complete porcelain coverage over metal and it is still
considered PFM.
That is what gives the crown a greyish appearance.

When I looked at the crowns, they were white on the inside as well.

Even though the after photo is out of focus, they look opaque to me.

Well, they don't look very good to me -- they l ook like chiclets!  I would
go back to the dentist immediately and tell him that these need to be redone
so they look natural, not like chiclets!!!  There's no reason for the shade
not to be better.
Call him tomorrow morning -- better yet, call today and leave a message and
then call again tomorrow.
