My Dental Implant Failed. What Now?

This is one of the hardest consultations I get, because the patient already spent the money, already went through surgery, and arrives convinced of one thing: that their body rejects implants. It is almost never that.

The message reads nearly the same every time: "I had an implant placed, it got infected, they had to remove it, and they told me I am not a candidate". And behind that sentence there is almost always a concrete cause nobody bothered to explain.

That is what this article is for: understanding why an implant fails, what can be salvaged, and how to ask for a second opinion that is actually useful instead of a second quote.

Rejection, in the sense you are thinking, does not exist

Immune rejection, like a kidney transplant, essentially does not happen with titanium. It is a biocompatible material: bone grows against it, it does not fight it. When an implant is lost there is an identifiable cause, and finding it is what determines whether it can be attempted again.

Telling a patient "you reject implants" closes the door with an explanation that does not exist. The right answer is to tell them why it failed.

The real reasons an implant fails

They split into two groups depending on when they happen, and they do not mean the same thing.

Early failure: in the first months, before the final prosthesis

• No osseointegration. The bone never bonded to the implant. Usually due to insufficient primary stability at surgery, poor bone quality, or overheating the bone during drilling.
• Post-surgical infection. Contamination of the site during or after surgery.
• Immediate loading indicated when it should not have been. Placing a provisional tooth the same day is excellent when the case allows it, and counterproductive when it does not. It depends on the stability achieved in surgery, and that is measured, not assumed.
• Active smoking. It measurably reduces implant survival, especially in this phase.

Late failure: years later, with the implant already in function

• Peri-implantitis. The most frequent cause. Bacterial plaque inflames the gum and progressively destroys the bone around the implant. It shows up as red or bleeding gums, bad odor, and bone loss on the radiograph. Caught early it is treated and the implant is kept. Ignored, it ends in losing the piece. It is a periodontal problem, which is why it is addressed through periodontics.
• Bite overload. A poorly distributed implant, or a patient with untreated bruxism and no night guard, receives forces it was never planned for. The prosthesis fractures, the screw loosens repeatedly, and over time the bone gives way.
• Inadequate surgical position. An implant placed at the wrong angle or depth may function for a few years, but it is impossible to clean and eventually fails. This is prevented with digital planning over a CBCT scan, not with a steady hand.

Notice the pattern: almost all of them are preventable with diagnosis and planning. Which is why the implant itself matters less than who planned it and how.

What can be done now

It depends on what the CBCT scan shows, so anyone giving you a plan without seeing one is guessing at your case. Broadly:

• If the implant is still in place and there is peri-implantitis: it can often be treated and kept. The surface is decontaminated, the infection is controlled, and bone is regenerated depending on the case. It does not always have to come out.
• If the implant has to be removed: it is removed, the site is allowed to heal, and we assess whether a bone graft is needed before placing a new one. The waiting time is defined by how much bone was lost, and it is decided with the scan in hand.
• If you lost a lot of bone and were told nothing can be done: that is almost never true. Severe bone atrophy is a reason to change technique, not to give up. Zygomatic implants anchor in the cheekbone instead of the upper jaw, and subperiosteal implants rest on the bone surface. These are low frequency procedures, so what matters is not that the technique exists, but how many cases like yours the operating team has actually resolved.

Surgery is performed by me or by the maxillofacial surgeon on the team, defined in the initial planning according to what your case requires.

What to bring to a second opinion (and what to demand)

A second opinion without this information is a quote, not a diagnosis. Bring:

• The brand, model and lot number of the implant you were given. Without that reference nobody can know whether the prosthetic component is recoverable or whether it all starts from zero. That is why I insist so much on brand traceability, which I explained in implant brands and scientific backing.
• The clinical record of the treatment. What was done, when, and with what.
• A recent radiograph or CBCT scan. Radiographs are not included in the evaluation fee, but they are always necessary. If you already have them, we use them; if not, you get an order to have them taken at the radiology center in the building next door. The 3D intraoral scan is included and done in the office, but it captures the surface, not the bone.

If the clinic that treated you will not hand over that information, insist: it is yours. And if they still refuse, you have learned something important about that clinic. Everything about warranties and responsibility I covered separately in warranty and follow-up for international patients.

If the failed implant was placed in another country

It is more common than it sounds, and it does not change the approach, only the logistics. The initial assessment is done by video with your radiographs, and if in-person treatment is needed the trip is planned with a closed quote before you buy a ticket. I have the logistics by country for the United States, Puerto Rico and Panama.

A salvage case has one advantage: since there is already a clinical history, we know what did not work. That is valuable information for not repeating it.

What I will not tell you

I will not tell you your case has a solution before seeing your scan. There are cases where the best recommendation is to wait, to treat the periodontal disease first, to stop smoking, or even to keep a removable solution for a while. You can review documented outcomes in clinical cases.

What I can tell you with certainty is that "you reject implants" is not a diagnosis. If that was the whole explanation you got, you deserve a second opinion.
