Dental implants are one of the most trusted treatments in dentistry. Studies consistently show a 95–98% success rate when placed correctly and cared for properly.

But what about the cases that do not succeed? In Gurgaon — where patients come to us from Sohna Road, South City, Golf Course Extension, Dwarka Expressway and across Delhi NCR — we see failed implants regularly. Some are from other clinics. Some, in rare cases, are ours.

Honesty matters more than marketing. So here is everything you need to know about why implants fail — and how to protect yours.

Why Implants Fail — The Two Types

Implant failure is not one single event. Doctors classify it into two types:

• Early failure — happens within the first 3–6 months, usually during the healing phase. The bone simply does not bond around the implant.
• Late failure — happens after the implant has been working fine. Often caused by infection, bone loss, or mechanical stress over time.

Both types need urgent attention. Neither should be ignored or “waited out.”

Cause 1 — The Implant Does Not Bond With the Bone

This is called osseointegration failure — and it is the most common cause of early implant failure.

Here is the simple version: after the titanium implant is placed in your jaw, your bone must grow around it and grip it tightly. Think of it like cement setting around a screw. If the cement never sets, the screw stays loose — and eventually falls out.

Cause 2 — Peri-Implantitis (Infection Around the Implant)

Peri-implantitis is an infection of the gum and bone around a dental implant. It is the leading cause of late implant failure — and the tricky part is that it can develop silently, without any pain, for months.

Think of it like this: gum disease destroys bone around natural teeth. Peri-implantitis does the same to bone around an implant. Once the bone is gone, the implant has nothing solid to hold on to.

How does peri-implantitis start?

• Bacteria present during surgery (poor sterilisation protocol)
• Dental cement escaping under the gum and getting trapped — this is more common than most patients realise
• Poor oral hygiene around the implant after surgery
• Skipping your yearly check-up visits

Who is most at risk in our patient population?

• Patients with diabetes — especially those with HbA1c above 8
• Smokers
• Patients with naturally thin gum tissue
• Anyone who does not clean the implant area properly every day

Cause 3 — Nerve or Soft Tissue Damage

The lower jaw has a major nerve — the inferior alveolar nerve — running through it. If an implant is placed too deep or too close to this nerve, it can press on it or damage it.

This is a placement error. It happens when dentists skip 3D imaging and guess the depth visually from a 2D X-ray. That approach is outdated and risky.

Signs of nerve involvement:

• Numbness in the lower lip, chin, or tongue that does not recover within a few weeks
• Tingling or burning sensation in these areas
• Pain that is different from normal post-surgery soreness

Some soreness and mild swelling after surgery is completely normal and expected for 3–5 days. But if you have persistent bleeding, severe pain, or numbness after 72 hours — call your dentist that same day. Do not wait for the next appointment.

Cause 4 — Not Enough Bone in the Jaw

When a tooth is missing for a long time, the jaw bone in that area slowly shrinks. This is called bone resorption. It is very common — and it catches many patients off guard when they finally decide to get an implant years after losing a tooth.

Without enough bone, there is no solid foundation for the implant. It is like trying to fix a screw into crumbling wall plaster.

The good news: in most cases, a bone graft can rebuild the area first. We do this commonly at both our Gurgaon clinics. The graft heals over a few months, and then the implant is placed in fresh, solid bone. Yes, this adds time — but it gives your implant a proper foundation to last decades.

Cause 5 — Habits That Slowly Damage Your Implant

Even a perfectly placed implant can fail if you are hard on it. Some habits cause damage so slowly that patients do not notice until a problem has already developed.

• Smoking — restricts blood supply, prevents proper healing, increases infection risk significantly
• Teeth grinding (bruxism) — creates excessive pressure on the implant crown and the bone around it. We fit a night guard for all bruxism patients before implant surgery
• Poor oral hygiene — plaque around the implant leads to peri-implantitis over time
• Skipping follow-up visits — small problems found early are easy to fix. Left for months, they become failures
• Ignoring post-op instructions — eating hard food too soon, skipping prescribed antibiotics, not cleaning with the correct technique

Warning Signs You Must Not Ignore

Your body gives signals before a complete failure. Learn these signs. They can save your implant if you act fast.

The single most important advice: do not adopt a wait-and-see approach. A small problem found today can be managed conservatively. Left for weeks, the same problem can mean losing the implant entirely.

What To Do If Your Implant Fails

Step 1 — Do not panic

Even a failed implant is not the end of the road. Many patients come to our Sector 51 clinic — some from as far as Faridabad and Noida — after an implant failure elsewhere, and we are able to treat and re-implant in most cases.

Step 2 — Contact your implantologist immediately

Tell your doctor exactly what you feel. Is it the crown that is loose, or does the whole implant move? Is there pain — constant, or only when eating? Any swelling? These details help us triage your situation over the phone and advise next steps.

Step 3 — Let the doctor assess before assuming the worst

In many cases, it is only the crown that has come loose from the abutment (the connector between implant and crown). This is a simple fix. The implant in the bone may be perfectly stable.

Step 4 — If the implant truly fails

The failed implant is removed carefully. The site is given time to heal. A bone graft is done if needed. In most cases, a new implant can be placed at the same site after healing is confirmed. Whether your original crown and parts can be reused depends on what is found on examination.
