What can go wrong with a dental implant?
Most implants function well for a long time, but problems can develop. Some are mechanical and relatively simple to fix; others involve the gum and bone and need more careful treatment. Common issues we see include:
- A loose or wobbly crown: often caused by a loosened screw rather than the implant itself.
- Fractured or chipped crowns: porcelain or the restoration can break under heavy bite forces or grinding.
- Broken abutment or screw: the connecting parts can fatigue over years of use.
- Peri-implantitis: infection and inflammation around the implant that leads to bone loss.
- Failed integration: an implant that never fully bonded with the bone, or that has lost its bond.
- Poor position or appearance: an implant placed at an angle that makes the crown hard to clean or visibly unnatural.
Who needs implant repair or retreatment?
If your implant feels loose, the gum around it bleeds, swells or recedes, you notice a bad taste or pus, or food constantly traps around the crown, it is worth having it assessed. Many patients come to us with implants placed years ago at another clinic or overseas, sometimes without records of the implant brand. We can still examine and, in many cases, identify and treat the problem.
Not every issue requires removing the implant. The right approach depends on what is causing the problem, how much bone remains and your general health.
How we diagnose and treat implant problems at E&D Dental
- Listening and examination. We ask when the problem began, check the gum, measure pocket depths and test the bite.
- 3D imaging. Our HDX/HBX low-dose CBCT shows how much bone surrounds the implant and reveals defects that flat X-rays can miss.
- Stability measurement. AnyCheck gives an objective reading of how firmly the implant is held in the bone, helping us distinguish a loose crown from a loose implant.
- Explaining the options. We tell you what we found, what needs treatment now, and what can be monitored. Decisions are made together.
- Treatment, which may include:
- Tightening or replacing a screw or abutment, or remaking a crown.
- Thorough decontamination of the implant surface and surrounding tissue for early peri-implantitis.
- Surgical cleaning, sometimes combined with bone and gum regeneration, for more advanced bone loss.
- Removing a failed implant, rebuilding the site with bone grafting if necessary, and placing a new implant after healing.
Any procedure is performed with our 3-step painless anesthesia system: topical gel or gargle numbing, Endo-Frost cold numbing of the injection point and computer-controlled anesthesia with electric stimulation. When a new implant is placed, it is planned digitally and treated with our UV surface activator before insertion.
Can I wait and see?
Sometimes waiting is reasonable, for example with mild gum inflammation that improves once cleaning technique changes. Bone loss around an implant, however, tends to progress quietly, and delaying treatment can reduce the options available later. We will tell you honestly which category your situation falls into.
Recovery and aftercare
Recovery depends on what was done. Replacing a screw or crown needs no healing time at all. Surgical treatment of peri-implantitis or implant replacement involves swelling and tenderness similar to the original surgery, and may require several months before a new crown is placed. Our TMJ physical therapy device can help reduce post-operative pain and inflammation.
Long-term success after retreatment relies heavily on prevention. We will set up a regular implant maintenance programme, review your cleaning technique and address factors such as smoking or grinding.
Limitations and honest expectations
Retreatment outcomes are less predictable than first-time implant placement. Bone lost to peri-implantitis does not always regrow fully, and some implants cannot be saved. Replacing an implant may require grafting and extra time. Parts for older or uncommon implant systems can be difficult to source, which can limit repair options. We explain these uncertainties before you commit.
Why patients in Gunpo and nearby cities bring their implant problems to us
- In-house CBCT and AnyCheck allow a clear diagnosis rather than guesswork.
- We evaluate implants from other clinics in Korea and abroad.
- Our approach favours the least invasive effective fix, such as a screw or crown repair, before considering removal.
- Whole-body care and vital-sign monitoring support older patients and those with chronic conditions.
