Dental Implant is Too Deep, Tooth Looks Long

Dental Implant is Too Deep, Tooth Looks Long

Dental implants, especially in the front of the mouth, need to be placed with a high degree of accuracy. When an implant is placed too shallow or worse yet too deep in the front of the mouth it creates a cosmetic failure– a long tooth and sometimes black triangles.

This is especially true on a patient who has what we call a “high smile line“. This is when you smile and you show more of your gums than average. If she had a low smile line, then it wouldn’t be noticeable when she smiles.

Here is an example of a patient that had an implant placed in about the year 2004. The dental implant was placed as an immediate tooth replacement which is a great option most of the time. Unfortunately the dental implant was placed too deeply into the bone. She hated this tooth.


When this happens you end up with a very long tooth. And worse yet, there is not a lot of good options that can be done to correct it once it is in this position. So in her case, I had to actually extract the implant and rebuild her jaw bone with 2 to 3 bone grafting and gum grafting procedures in order to put a new implant in a more shallow position. A block bone graft was needed also.

This is about as difficult as it gets. This case is difficult because I had to regrow bone vertically, closer to the edge of the natural teeth. Building bone vertically rather than horizontally is always more tricky and requires several very advanced techniques.

You can see in the picture with the white dental implant custom abutment, that the new implant is at a better level because the gumline is more even with the tooth next to it.


Unfortunately the deeply placed implant permanently stripped bone off of the teeth on the side, and that is not repairable.

Compare the levels of the two implants on the x-rays.  One is much more shallow than the other. The shallow one was placed by myself and the deeper one was placed back in 2004 by another dentist.

Occasionally you can recover a deep, long tooth implant with a new custom abutment and gum graft. But I caution you that this is truly a very difficult procedure and should be completed by an expert in implant dentistry so that you can anticipate a result before you ever even get started.

    Do you have any contacts that you would trust with this procedure in the Netherlands ( I am currently working here) or Northeast (US – I will repatriate to Boston when my assignment is done).

    thank you for the very well written explanation…my friend went to a really cheap dentist and ended up looking this way. It was one of those billboard/radio advertisers. I need an implant too…I will be calling your office.

    I just had an implant, crown placement within the last 4 weeks, on my front tooth and have similar results, the gum is 1/2 inch higher on my implant tooth than my other front tooth. I am worried sick about it. My Dr. wants to “wait and see” he said gum grafting wont work and that “nothing is perfect in life”. Meanwhile I shy away from talking to people and I cover my face when I talk. I’m panicked that this is how I’ll have to live now. Do you think it’s too late? Can anything be done? Thanks for any suggestions.

      Hi Jean,

      If it is the final crown rather than a temporary crown, your gum is not likely to come down and cover it. 🙁
      Typically on a complex single front tooth I will try to work out all of the aesthetics and gum positioning in the temporary phase. As long as the teeth on either side is healthy and the implant is positioned with substantial bone on the outer wall, the dental implant can be made to look extremely natural.

      It may not be too late to try other options such as removing the crown and placing a temporary but I am assuming you already went through all that stage.

      Some situations no matter what you do are compromised from the beginning and the dental implant will look longer than the other teeth. I have many patients like him to me in the same situation The point is to predict this in advance so that there are no surprises in the end. This is something I spend a ton of time on with each patient so they can understand their final result before anything is ever begun. I know hindsight is 20/20 and doesn’t help too much.

      Let the tooth stay the way it is until about 8-12 weeks after it was placed. That will likely be the final resting place of the gum tissue. At that point you can make some determination with what you want to do.

    A fantastic article, showing me the benefits of implants and the reality of implants. It exactly tells me the procedure of impalnts. very beneficial read.

    Thank You

    Hi, is what you did here called an autogenous bone graft? then a gum tissue graft? I’m 57 yrs old, and in need of implants over teeth 7, 8, 9 and 10. the cuspids are ok, but also shave a good deal of gum loss. The teeth are still in with the exception of 10 right now, but tooth 9 looks exactly like your patient above, the gum height is dramatically different between 8 & 9. I’m afraid the oral surgeon just wants to put the implants in, and move on. He says when the teeth are extracted and bone is added there won’t be enough bone to support a tissue graft. I’ve been to an oral surgeon and a periodontist, the oral surgeon says the teeth will have to be made larger, and the periodontist says i could get a prosthetic built on the implant crown bridge.
    I’ve told both that I’d like to have gum grafting done, and am willing to get the additional bone but i don’t know why (i’m am in good health) they don’t seem to want to do this.
    Do you see a reason why what you did to the above patient wouldn’t work for me to even out the span in my front teeth? I don’t smoke, have good oral routine, and I’m an easy patient. Thank you so much,

      Hi jojo,

      I don’t really know why a tissue graft would not be done. Without seeing you it is very difficult to know your exact situation though.

      If the Implant is already done and the crown is on, a tissue gum graft is not going to cover over the crown on the dental implant.

      Some situations with dental implants are unrecoverable.

      Sometimes you have to extract all the implants and start all over.

      This is why excellent pre-planning and very good execution of dental implants is so important.

      Dental implants are body parts so I suggest you seek out the best person possible. It sounds like you have a very complex situation.

      Dr. Amin

    Hi Dr. Ramsey.

    I had two teeth removed. Reason: infected. Broken. Bone was gone.

    My dr did “bone grafting” for him to be able to place the implants. He closed it to heel for 6/7 months. He then applied the implants.

    The implants are next to each other. They are both long. Very white. Exactly like the patient in this picture (not front teeth though, back.)

    Even though he did bone grafting. I feel that it was completely medical. And not cosmetic at all. I lost width in this area. My bone was wider. And nicer looking.

    Now when I smile. You can see long white ugly teeth. Not in rhythm with the rest of my teeth. And darkness on top of these two teeth. Due to lack of “width of bone” in this area.

    My concern is can all the width be restored? Even length of gum? And what should I say to my doctor?

    If I need to change my dentist. What specialty should I be looking for in a dentist? Is there a specific type of dentist that could fix my smile?

    Thank you,

    1. Meera

      To be more clear. The two teeth that where amputated and replaced by implants are (First molar and second premolar)

    2. Ramsey Amin DDS

      Hi Meera,

      You likely have loss of vertical bone rather than width. As soon as the bad teeth were extracted the underlying bone loss that was hidden by your gums became much more apparent. The bone graft was likely only done to preserve what you had but not to build back to its original height.

      Once the implants are in, there is not many good options except for removing them and starting all over

      sorry for the bad news.
