Failed Dental Implant Repair in NYC: Fixing Problem Implant Teeth

Many problems with implant teeth involve the crown, screw or abutment rather than the implant itself, and the first step is working out which one has the problem.

Restoration problem or implant problem?

A dental implant tooth has three main parts: the implant, which is anchored in the bone; the abutment, which connects to it; and the crown, which you see and chew on. A problem in any of these can make the whole tooth feel like it has failed.

In practice, it helps to separate two kinds of trouble:

  • Restoration problems. Loose screws, broken or chipped crowns, poor contours and gaps that trap food. The implant in the bone is usually still sound, and the parts above it can often be repaired or remade.
  • Implant and gum problems. Inflammation and bone loss around the implant, or an implant that is no longer fused to the bone. These are biological problems and may involve a periodontist or oral surgeon.

Systematic reviews show that implants generally have high long-term survival, but technical complications such as screw loosening and porcelain chipping are among the more common issues over time. Many of these can be addressed without removing the implant.

Common problems with implant teeth

Loose or broken screws

A crown that wiggles, clicks or feels slightly different when you bite is often a loose abutment screw rather than a loose implant. A screw that keeps loosening usually points to a cause, such as heavy bite forces, grinding, a poor fit between parts or a crown shape that loads the implant unfavorably. Occasionally a screw breaks inside the implant and needs to be carefully retrieved.

Fractured or chipped crowns

Porcelain can chip, especially in people who clench or grind. Small chips can sometimes be polished or repaired. Larger fractures usually mean a new crown, often in a stronger material such as monolithic zirconia, along with a look at the bite and a night guard where appropriate.

Food impaction

Food packing between an implant crown and the neighboring tooth is common. Natural teeth can shift slightly over the years while the implant stays fixed, so a contact that was tight can open up. Depending on the cause, the fix may be a new crown, a modified contact or an adjustment to the neighboring tooth's restoration.

An implant in an unfavorable position

Some implants are placed too far forward, too deep or at an angle that makes a natural-looking, cleanable crown difficult. Angled abutments and custom-designed parts can often make up for some position problems, although they cannot change where the implant sits. When the position is too far off, a new crown may not solve the problem and removal and replacement may be discussed.

Peri-implant mucositis vs peri-implantitis

These two terms describe gum problems around implants, and the difference matters.

Peri-implant mucositisPeri-implantitis
What it isInflammation of the soft tissue around the implantInflammation plus progressive loss of supporting bone
Typical signsRedness, swelling, bleeding when cleanedBleeding, sometimes pus, deeper pockets, bone loss on x-rays
OutlookGenerally reversible with better cleaning and careNeeds active treatment and may lead to implant loss

Mucositis is often linked to plaque buildup, and the crown's shape can make cleaning harder. That is where the restoration and the gum problem overlap. Crowns with bulky contours or excess cement left under the gum can contribute to inflammation, so correcting the restoration is often part of treatment.

Peri-implantitis is usually managed together with a periodontist, who may clean the implant surface, treat the infection or perform surgery to address the bone defect.

What can be redone on the restoration side

When the implant is stable and the bone is healthy, Dr. Lal can often:

  • Replace a loose or damaged abutment screw with a new one tightened to the manufacturer's specification.
  • Remake a crown with better contours, a tighter contact or a stronger material.
  • Change a cemented crown to a screw-retained design where the implant angle allows, which makes future maintenance easier and avoids cement under the gum.
  • Replace a stock abutment with a custom-designed one to improve angle, emergence and gum support.
  • Adjust the bite and provide a night guard if grinding is contributing.

Identifying the implant system is a key early step. If the brand is unknown, x-rays and the visible parts often allow identification. Designs are produced with intraoral scanning and exocad, and the in-house LAL Dental Laboratory allows close coordination between the clinic and the lab. More on this process is on the digital dentistry page, and implant crowns in general are covered under implant restorations.

When the implant itself may need removal

Removal is considered when:

  • The implant body itself moves. This usually means it is no longer fused to the bone.
  • Bone loss is advanced and continuing despite treatment.
  • The implant has fractured.
  • The position cannot support a functional, cleanable tooth.

Removal is usually done by a periodontist or oral surgeon. Bone grafting is often done at the same time or later. Healing before a new implant is typically several months, and the new implant then often needs a further few months to integrate before the final crown. A cone beam CT scan and a digitally planned surgical guide help in planning the replacement position around the final tooth. Dr. Lal's master's research and early publications focused on these guided approaches.

When several implants or a full arch are involved, see full-arch implants.

Urgent signs

Contact a dental office promptly if you notice:

  • Swelling, pus or a bad taste around an implant.
  • Pain that is new or getting worse.
  • Movement of the implant itself, not just the crown.
  • Numbness or tingling in the lip or chin.

Facial swelling with fever, or any difficulty swallowing or breathing, needs emergency medical care right away.

A loose crown is usually not an emergency, but it should be seen soon. Chewing on a loose implant tooth can damage the screw or the internal connection of the implant.

How an evaluation works

  1. Records. Bring any information you have about the implant, past x-rays and scans.
  2. Exam and imaging. Gum measurements, bite check, x-rays and, when needed, a CBCT scan.
  3. Diagnosis. If the crown is screw-retained, it can often be removed to check the parts directly.
  4. Plan. A written explanation of whether the problem is on the restoration side, the biological side or both, and who would be involved.

Simple screw problems can sometimes be resolved in one or two visits. A new crown typically takes two to three visits over a few weeks. Cases involving gum treatment or replacing the implant take longer. A second opinion visit is a common starting point for patients in Manhattan with implant work done elsewhere.

Maintenance

Implant teeth need daily cleaning, including floss, interdental brushes or a water flosser around the implant. Professional cleanings and periodic x-rays help catch bone changes early. A night guard is often recommended for people who grind.

What drives cost

Cost depends on whether the fix is a screw, a crown, an abutment or the implant itself, whether parts for the implant system are available, the materials used and whether gum treatment, grafting or another specialist is needed. See dental implant cost for more detail on these factors.

Questions

My implant crown is loose. Does that mean the implant failed?

Not necessarily. A loose crown is often caused by a loose abutment screw, which can usually be tightened or replaced. An x-ray and exam show whether the implant itself is still stable.

Can a crown be replaced on an implant placed by another dentist?

Often, yes. The implant system needs to be identified so compatible parts can be used, which is often possible from x-rays and the existing components, although parts for some older or less common systems can be hard to get.

What is the difference between peri-implant mucositis and peri-implantitis?

Mucositis is gum inflammation around an implant without progressive bone loss and is generally reversible. Peri-implantitis involves bone loss as well and needs active treatment, usually with a periodontist.

Who removes an implant if it has to come out?

Removal is usually done by a periodontist or oral surgeon. Dr. Lal coordinates the plan for the replacement tooth and the timing of any new implant.

Why does food keep getting stuck next to my implant?

Natural teeth can shift slightly over time while implants stay fixed, which can open a gap. A new crown or an adjusted contact often corrects it.
