    Default OT/ Can gold crown be re-used after root canal

    I have a tooth that has been giving me quite bit of pain and I think I may need a root canal. The tooth currently has a gold crown on it. My question is, can the crown be removed and re-used? I know there is at least one dentist on this forum. Thanks. Joe

    They never re use mine. I have wondered the same thing. At least I make them give me the crown. I have 3 or 4 by now that I could melt down and make into something. But,I think they are only 10k gold,which is the lowest alloy that can ce called gold. Also known as "New York gold".

    Many years ago, I had a root canal done on a tooth with a gold crown. They simply drilled through the top of the crown leaving it cemented in place. They removed the root and filled the hole in the root, maybe with a titanium pin, but I don't remember. Then they did a conventional amalgam filling on the top of the crown. So, no risk of damaging the tooth or crown in trying to pull it off the tooth, and no $1000 bill for a new crown. It all went well.

    Ok - thanks. I was hoping they could just remove it and do the root canal and replace it. Seems like it ought to be a fairly simple process - one visit and your on your way. Being toolmakers and machinists we tend to look at things differently.

    When they do the root canal and buildup it would be very difficult to match the original contours to be able to re-cement the crown. If they can not drill through to do the root canal then it will have to be replaced. Been there done that both ways. Lots of experience here as my parents thought that in the 50's all cavities should be removed by grinding the center out of every tooth and filled with an amalgam that had a 30 year life span. I think I might still have two or three live teeth in my face.

    Don't wait too long.
    After one crown, Within a month I kept telling a former dentist there was pain and infection in that area. He kept denying it. This went on for 2 years. He even sent me to a specialist to work on a different tooth behind it. The specialist said "There's nothing wrong with this (the other) tooth. "(name of orginal dentist)needs to do some basic dentistry, I can't really say more". Went to a close friend's son/ recent military dentist. He gave me a reference to another specialist. She went in through the crown as Larry describes, but it was too late. Too much decay in the tooth and bone. So I lost it.

    (She later did another tooth and saved it.)

    So, as has been mentioned, they go right through the crown and no big deal. Just don't wait around.

    ask your dentist....they have a small drill that they can take down the center of a crown that's new and not disturb it and do a root canal and then fill in the hole with porcelain all while keeping your crown

    Thanks guys. There was a dentist in town that I really liked. He recently retired and sold his practice to a "non-native English speaker". I went to him about a month ago and he did an xray and said there was no problem. Well, the discomfort has gotten to the point where I am losing sleep. I will not be going back to that dentist. I like to have more than 50-50 confidence that I am being understood by my medical practitioner.

    Today being Wednesday not much I can do till tomorrow. I will try to get in with someone tomorrow.

    It's interesting to hear the stories of dentists and poor practices and how they deny it to the end. My mother in law had a titanium post put in after a root canal. Couple weeks later her face and throat swelled up to where she almost couldn't breathe. She got lucky, could have been a lot worse. Went to the ER and they said it was an allergic reaction, but they had no idea what it was from. They tried narrowing things down, and they went back to the original dentist who X-rayed the tooth and all looked fine. He said if it was an allergic reaction to the titanium, there would be swelling, but there was none on the X-ray. Well problems persisted and she finally went to a different dentist who did some sort of 3D x-ray on the tooth and found not only a decent amount of swelling, and infection around the post, but the X-ray also showed that the post wasn't even put in straight. Removed the post, no more problems. They actually told the original dentist the findings and showed him the X-rays and he still denies it. I guess they just make too much money to be wrong.

    Serious tho, I've had to have several crowns replaced. Never had anyone suggest drilling thru the old one, but a couple were because of decay in the tooth, had to be ground out.

    But one was with 30yr old crown on a tooth that had had root canal. Turns out there was still some root left along with a bit of broken off reamer in the tooth. WTF? New root canal and crown, $$$.

    Never had a dentist suggest going thru the old crown before.

    'Dental' gold alloy, was traditionally 22K. Yellow version anyway. "White" gold MUST have more of other elements. Payback is that it is harder, stronger, not quite as obvious if a person has to open his mouth frequently. As with Silver-Mercury amalgam, white gold is also something of a Biocide. Yellow Gold doesn't interfere with microbes. Cuts both ways, that attribute set - reduced decay, halitosis, vs possible allergies, long-term heavy-metal effects. Humans are Biological critters, just as Microbes are.

    Used to be the pennyweight of removed Gold was an offset to the cost of new gold used. It isn't usually all that much compared to the Dentist's skilled labor. Dentist is also in a better position to have it recycled than Joe Average ordinarily is anyway.

    The 'primary' re-refiners - those with the highest percentage of recovery and payback, even paying on trace metals - do not want stray sources of materials, only traceable, reputable, and established ones.

    Helps keep their slender margins from being consumed if found to be processing stolen metals.

    That said, about once a year, someone brought in salvaged dental gold into our firm to be crafted into a pendant and set with diamonds or such. Sometimes recovered from a deceased spouse. At 22K, it was actually a bit too soft to easily insure retention of the gemstone. Needed more metal, shrouded the stone more than our usual 18K or 14K.

    Y'know humans? Strange folk some days.

    Last time I had bridgework replaced (two crowns with a tooth hung between them) there was NO WAY the crown was coming off
    in one piece. Took him a good half hour to cut those things off the nubs of the teeth underneath.

    My guess: if he tries to remove the crown intact, the tooth will come out with it.

    No - I'm over 15 years with a full cap over a mere shard that the Dentist told me the same thing. If/as/when ever a root canal IS needed, he would drill a small diameter hole through from the top to do it.

    My view is when a root canal is on the menu, that tooth may as well come out anyway.

    Absent an active nerve and the blood vessels it calls upon, it becomes no more than a porous birdhouse for microbes to feast on and hide within.

    YMMV

    Keep in mind that what's possible for person A's tooth may not be possible for person B's tooth.

    I encountered this situation late last year when I totally shattered a bicuspid (pulp cavity had completely rotted away inside leaving just a shell of enamel, and yes this would have been detected if I'd been to the dentist in the previous decade). My dentist sent me to a root canal specialist, who took one look and said there wasn't enough tooth left to support a crown after a root canal. So I was then sent to an implant specialist who extracted the tooth and did a bone graft. Even at the implant specialist there were several possibilities: extraction with immediate implant, extraction with bone graft, or extraction with crown bridge. The root of the tooth was very close to the sinus cavity, which eliminated the immediate implant option in my case. The surrounding teeth are apparently completely healthy, which made a crown bridge a really poor choice.

    I'm getting ready to have the implant surgery next month, and then have a cap glued onto the implant stud about three months after that.

    My point: There were at least four, maybe five, different potential treatments in my general situation (busted tooth), but the specific situation eliminated most of those possibilities.

    in these parts most dentists won't do a root canal they refer you to a specialist.
    wife's daughter has a practices in SF says it's to hard to do it right with out
    the special equipment.
    and yes they just drill a hole and fill it on a crown.

    proper root canal isn't a one visit and done some times they do a temp filling and then open it up again
    to check that it's all good in a few weeks.

    point is time and money spent going to specialist is well spent in the long run.

    granted I do live in an area where the standards of health care are very high, get out in the sticks
    and you might get different views.

    Like any speciality, the capability of dentists vary a lot. I went to a very good dentist for more than 40 years. After he retired I went to the young lady dentist that purchased his practice. She did such a poor job in putting a composite filling in a tooth that I wondered how she got out of dental school. I found one I liked, but his mechanical skills were not as good as the one I had learned to trust. I now have three implants, two bridges, and a number of crowns. At 86 hopefully what I have will see me out.

    Very nearly has to do.

    Dentists and oral Surgeons wouldn't go near Mum from about 87 onward. Strong heart, unbelievable fast healing, non-responsive to most painkillers, but she had never needed them anyway. Great health in all respects save a colon cancer that had responded to an operation and gone slow-moving.

    One of them wanted her to have a Pacemaker installed before he'd risk putting her under. Heart-lung machine was on the menu with a different one.

    Sod that - she went over to sharper knives, soups, stews, and soft foods 'til punching out with but one tooth left at 92'ish.

    Line you up a minder that is a world-class cook, many small but nutritious treats a day. Meals remained her joy.

    My dentist is about the same age as me and has been gaining skills and machinery and gadgets all the way along. Does his own crowns, implants and root canals. Had a root canal fixed in a gold crown - he has an amazing collection of high tech drills and other gizmos - my wife had the same thing done a week or so ago.
