patient getting teeth examined by dentist

UPDATE: September 2020, the Court decided to extend the supplemental claim period by 12 weeks in order to cover debonds that were fixed through Sept. 7, 2020. The new deadline for supplemental claims is Dec. 8, 2020. Class Members may begin filing for supplemental claims on Sept. 21, 2020. 

Dentists have secured a $32.5 million settlement in a class action alleging 3M made defective dental crowns.

Class Members include dentists and dental practices in the United States who purchased 3M’s Lava Ultimate Restorative and used it as a dental crown before June 15, 2015. Dental patients must have also experienced debonding of the crown before June 15, 2020.

A group of dentists accused 3M of violating the terms of the warranty for their dental crown bonding product, Lava Ultimate Restorative. The product is a ceramic material that is meant to dry and form a crown in dental procedures.

Dentists complained that the 3M dental crown product was unbonding before its 10-year warranty.

As patients came back with issues, dentists who used Lava Ultimate Restorative allegedly had to repair and replace the dental crowns at their own costs.

3M fought back, asking a federal judge to dismiss the class action lawsuit arguing the claims were not specific enough.

Though the 3M dental crown class action lawsuit was trimmed of some claims, the company agreed to settle.

Under the terms of the class action settlement, Class Members can receive either full reimbursement for out-of-pocket costs related to the debonding of 3M dental crowns or $250 per debond.

To make a claim Class Members must submit a Claim Form online.

Class Members have until Aug. 8, 2019 to submit a claim for debonds that occurred on or before May 10, 2019. In addition, Class Members have until Sept. 15, 2020 to file a claim for debonds repaired between May 11, 2019 and June 15, 2020.

Class Members who wish to exclude themselves or object to the 3M dental crown settlement must do so by Aug. 14, 2019.

Who’s Eligible

Class Members include dentists and dental practices who bought and applied 3M’s Lava Ultimate Restorative before June 15, 2015. The product must have fully or partially debonded prior to June 15, 2020.

Potential Award

$250 per debond or 100% reimbursement for out-of-pocket expenses.

Proof of Purchase

Notice ID must be provided. Class Members claiming out-of-pocket costs must provide documentation of the expenses.

  • R. Schilling October 20, 2020

    Kindly include me, my crown came off within 9 months!

  • Lora Keena October 17, 2020

    I JUST found out about this and I’m furious. My husband had a broken crown and I had one come off. I still have an infection under the root canal and new crown that were required when the original crown fell off. I don’t understand why the patients aren’t being helped with this period. I have more crowns and that are going to fall off based on the situation and I’m going to have to pay for it all over again. My dentist has provided no financial relief, hasn’t admitted to a thing, and is actually trying to hide it from me. This isn’t over.

  • Douglas deering October 1, 2020

    Please add douglas deering 4 of his crowns have fallen out and he had to pull those teeth the dentist who was responsible for doing these root canals did not fix it and they are terrible and painful

  • kimberly fretwell September 30, 2020

    ADD ME

  • Gerry Hamner September 28, 2020

    Why aren’t the patients eligible for this….My crown came off and I was fortunate enough to not swallow it. The dentist reattached it and less than 3 months later, it lost it’s seal and allowed bacteria to get under it, causing a nasty infection. My dentist would NOT repair this without recharging me……after a year or so, the same thing has happened again and he again will NOT do anything to fix it without charging me again. This is totally pathetic and wrong. I have had multiple infections under this defective crown. In fact, I’ve had one for the past 3 days including right now as I type this. We the patients should receive compensation, including for unnecessary pain & suffering. Us patients should start our own class action against 3M for this!!!

  • Amanda Ridings April 8, 2020

    I had 3 of these crowns come out and I’ve had to pay out of pocket for them to be rebonded at other dentist offices. One of my crowns came out while eating and I cracked it in pieces so now I need a whole new crown!! Where is our compensation as patients?!!!

    • Hillary August 19, 2020

      Yes! Exactly what I want to know!! My dentist didn’t repair the work either and it cost me 2 teeth. I bet over 1/2 the people who had a crown de -bonding, have not had a dentist offer to have it fixed free and as a result have suffered needlessly.

    Yes, what if the dentist is no longer in business? In October 2019, I woke up with the crown to my lateral tooth in my mouth. I had to have a flipper made and pay for that oh, because I couldn’t afford another option. Please let me know if I am eligible.

  • Tracey Freitas January 2, 2020

    What if the dentist is no longer in business? My crowns were done prior to 2015 and I no longer have the receipts nor have I been able to fix the debonding.

    • Tracey Freitas January 2, 2020

      I guess I would have liked the class to be for the patients as well.

    • Karen Lavandowski April 3, 2020

  • Jeanette K Troutman June 26, 2019

    This lawsuit if for the dentists who used the products but it doesn’t cover patients who had to go through double procedures. Is there another class action for the patients?

    • Myron Lewis July 26, 2019

      You should start up a class action lawsuit 4 the patients that received these crowns that were defective!

      • Jon Soderena October 27, 2019

        We need a class action for the patients that had to pay double for these crowns! I
        had 3 that were defective and can’t afford to replace them.

  • RAYMOND BOTTS June 26, 2019

    add r. botts. my crown fell out and I cannot afford to repair it. I also want to know if there’s a class action on tooth implants. I have a crown that fell out and a failed tooth implant the dental office that did it refuses to fix. then they want to charge me $89 just to tell me what I knew already. then quote over $3000 to fix it which is more than a new crown.

  • Sandra Douglas June 19, 2019

  • Cynthia Weber May 19, 2019

    I had one put on but it only lasted a few years. I couldn’t afford to pay for another.
    Sad thing is that without that I had uneven teeth. Which caused chipping in other teeth.
    I could never get them fixed because of reversal of fortune.
    Do I qualify , anyway?

  • Nicole Hallada May 14, 2019
