Broken Molar. Patch? Crown? Root Canal?

    I had an inside cusp break off my molar 9 years ago. I had
    my dentist just put in a filling, since I was afraid of getting a
    crown. The tooth has been fine, up until now. The other inside cusp
    just broke off while chewing !

    Will see the dentist soon, and will have to decide what to do.
    Will ask him to just "patch" the cusp with something. I have a feeling
    he will not do that.

    The inside of the tooth has a base of silver colored metal filling,
    on top of the root. On top of the silver metal is white colored
    filling material, and natural tooth. I am hoping he can fill in the
    missing cusp with more of the white filling material.

    I have saved the broken off cusp. It has dark discoloration on
    it, which of course could be decay, or possibly is colored from the
    silver metal it was adhesed to. I'll show it to the dentist.

    No pain anywhere in teeth. All the damage is above the gum line
    ( assuming no decay).

    If I get a crown, will a root canal be needed ? Can the dentist
    use the existing metal base inside the tooth for mounting the
    crown ?

    The dentist took bitewing xrays 6 months ago, no mention of decay

    If I need a root canal, why ?

    Thanks in advance

    You'd only need a root canal if there is decay close to the nerve or
    the tooth broke close to the nerve, but since you arent having pain,
    it sounds unlike that you will need one. With 2 broken cusps, sounds
    like you need a crown, IMO.

    First I would like to say that I agree with Dr. S. Bornfeld entirely.
    In my practice that would be unlikely.
    A good idea. Note that discoloration is a sign of long term leakage.
    So far so good, but it is be to not ass|u|me anything without
    a thorough examination.
    IMHO any tooth, especially a first molar 3/14/19/30 that we humans
    get at about 6 years of age, that has fractured, and has been operated
    more than twice, will likely suffer irreversible pulpitis, quickly
    followed by pulpal necrosis after just one more operation.
    Yes, but not recommended.
    In fact all previous filling materials should be removed, and a
    build-up should be done for a crown preparation.
    Amatus will disagree, but for his way of restoration, with Cerec,
    I would agree with him.
    Even Amatus removes all old filling materials.
    Fractures, unless super severe, do not show on X-Ray
    Trauma is additive, that is to say each minor trauma
    adds to the previous and subesequent traumas.

    Cannot diagnose your tooth over the internet.
    If You would post your X-Ray I would be glad to give
    you my opinion.

    Please remember that my opinions over the internet
    are worth less than what you paid for it. ;^]]

    Thanks for the responses. Keeping my fingers crossed that I don't
    need a root canal.

    Saw the dentist. Verdict: NO ROOT CANAL NEEDED ! Yay !!! I
    didn't even mention the words "root canal" to him. I just showed him
    the broken tooth and waited for his suggestion, which was to put on a
    crown. Man, am I relieved.

    I think I will opt for a gold alloy crown with no porcelain. He said
    the all gold alloy was the way to go, as far as longevity of the

    Did the dentist pulp test the tooth?

    Not sure what a pulp test involves. A tech probed the tooth gently
    in one spot, with a metal pick, and asked me if it hurt. It didn't.
    Dentist came in about 10 minutes later and looked at the tooth, but
    did no poking at it, just looked at it. No X ray taken that day, but
    I had bitewings done about 4 months ago, and they were displayed up on
    the monitor. Also, he had filled this tooth 8 years ago, and had
    reviewed his notes about it, before coming in.

    A pulp test would involve either putting cold or heat on the tooth or
    an electric impulse. Sometimes even blowing air on the tooth can help.
    A bitewing Xray doesn't normally show the area around the end of the
    root which is where an abscess would usually be seen. The pulp could
    well be nonvital without an abscess being seen.
    Without the tooth being checked, you really have no way of knowing if
    it needs a root canal.

    Oh, I forgot. The tech also blew some air on the tooth. I thought she
    was drying it out for the dentist to do something to it, Maybe she was
    watching to see if I winced.

    I have never had pain in this tooth since I got it filled 8 years
    ago. Could the pulp have died off by itself, with no pain ?

    I used to wear a plastic bit on my lower teeth at night to keep
    the teeth from migrating. If I forgot to wear it for a couple nights,
    the next time I put it in, I would sometimes feel the bit pushing on
    certain teeth, sometimes the front, sometimes the sides, including the
    molar in question. God forbid this occasional pressure on the molar
    caused it to crack, even down to the pulp !!
    Wouldn't I feel pain if the tooth cracked, in the pulp area? Just
    bringing up the nightmare scenario, if you will excuse me.

    I have stopped wearing the bit ever since my molar broke. I don't
    want to have any pressure on the molar, and especially not on the good
    crown I have on the other side of the jaw, on the bottom. If my teeth
    migrate, they migrate. Maybe I will have a new bit made up, after the
    new crown is in.

    I only got the bit because I asked the dentist what I could do to stop
    my lower teeth from migrating forward, and worsening my underbite, and
    he said this bit (retainer?) thing would do the trick. .

    Given what I have stated about the molar, wouldn't you guys say that
    I ** probably ** don't need a root canal ?

    Did you feel anything when the air was blown onto the tooth?
    A definite possibility. I'm not saying that it definitely has but it
    certainly could.
    Not if the pulp had died.
    Depending on the situation, they can move quite a bit.
    I can't tell from what you've said.

    Must tell you that the diagnostic signs and symptoms of irreversible
    pulpal distress and imminent necrosis that were taught during my
    dental student days were *severely* lacking at best.

    And that is being generous to the instructors.
    But we must remember where they come from.

    So to be more accurate, one must have more information.
    Both subjective and objective.

    Don't know anyone who can diagnose over the internet
    from only a description of symptoms, even though that is
    an important part of the history.

    Post pictures, and radiographs (x-rays) for a better
    analysis of your condition if possible.

    Ain't internet tooth diagnosis difficult ?

    I haven't heard anything that tells me that the pulp is vital. It may
    be but it doesn't seem to have been checked. Endo can be done through
    the crown but it is better to do it first if it is necessary.

    Don't Patch It - Fix It Right!!

    Brian, please read my recent post. Sounds exactly how my problems started. My advice is to not keep patching it - bite the bullet (no pun intended) and get it taken care of correctly (probably a crown). Save the tooth while its still save-able!!!
