Short answer The main signs of a failing dental implant are an implant or crown that feels loose, gum around it that bleeds, swells or releases pus, pain when biting, a receding gum line showing metal, and bone loss on an X-ray. Failure is uncommon: large reviews find about 93–96% of implants still in place after 10 years. Many problems caught early, especially gum inflammation, can be treated and the implant saved. Medically reviewed by [Prof. Nouran Abdel Nabi](https://elnabidentalclinic.com/en/dr-nouran-abdel-nabi/) · Last reviewed 19 October 2026 Implant failure is uncommon, but it does happen, and catching it early often makes the difference between a simple clean-up and losing the implant. Large reviews find that about 93–96% of implants are still in place after 10 years. The remaining few percent fail for reasons that are usually identifiable, and some problems that look alarming, such as a loose crown, are not implant failure at all. If something feels wrong with your implant right now, this page explains which signs matter, what they usually mean, and what you should do next. ## What are the symptoms of dental implant failure? - **Movement.** The tooth feels loose or clicks. This may be a loose screw or crown, which is fixable, or the implant itself moving in the bone, which is more serious. - **Bleeding, swelling or redness** of the gum around the implant, especially when brushing. - **Pus or a bad taste** coming from around the implant. - **Pain or tenderness when biting**, or a dull ache that does not settle. - **Gum recession**, where the gum line drops and the metal or a grey shadow becomes visible. - **Food packing** around the implant more than before. - **Bone loss on X-ray**, which your dentist may see even before you notice anything. | What you notice | Common causes | How urgent | | --- | --- | --- | | Crown loose or clicking, without pain | Loose abutment screw or cement failure | Book soon; avoid chewing on it | | Bleeding gum around implant | Peri-implant mucositis (early, reversible inflammation) | Within a couple of weeks | | Pus, swelling, bad taste | Peri-implantitis or infection | Within days | | Whole implant moves | Loss of bone bonding | Within days | | Swelling spreading to face or neck, fever | Spreading infection | Same day; seek urgent care | ## Early vs late dental implant failure ### Early failure (before the final tooth is fitted) Early failure means the bone never bonded properly with the implant. It usually shows within the first weeks or months as pain, infection or a loose implant. Common causes include infection at surgery, poor initial stability, overheating of the bone during drilling, smoking, uncontrolled diabetes, and putting pressure on the implant too early. ### Late failure (months or years after loading) Late failure means an implant that was working well loses its support later. A review of late-failure studies linked it to a history of gum disease, radiotherapy, teeth grinding, poor bone quality, low stability at placement and inflammation around the implant in the first year ([systematic review, PMC](https://pmc.ncbi.nlm.nih.gov/articles/PMC7312800/)). The most common biological cause is peri-implantitis; the most common mechanical causes are overload and broken components. ## Dental implant failure after 5 or 10 years: why does it happen? When an implant fails after several years, the story is usually gradual: plaque collects around a crown that is hard to clean, the gum becomes inflamed (mucositis), and if this is not treated it can progress to peri-implantitis, with slow loss of the bone holding the implant. Smoking, past gum disease, diabetes and skipped check-ups all speed this up. Heavy grinding can add mechanical overload. Because it often causes no pain until a late stage, regular X-rays and gum checks are your early-warning system. ## What is the dental implant failure rate? Figures vary with the patient group and how failure is defined, but a widely cited 2019 meta-analysis found about 96% of implants still in place at 10 years, or about 93% using a more cautious analysis. In other words, most patients never lose an implant, but a small minority do, and the risk is higher in smokers, people with uncontrolled diabetes or a history of severe gum disease. For how long implants and crowns typically last, see [how long do dental implants last?](https://elnabidentalclinic.com/en/faq/how-long-do-dental-implants-last/) ## How is a failing dental implant treated? Treatment depends on the cause and how far it has progressed: 1. **Mechanical problems** such as a loose screw or chipped crown: the screw is retightened or replaced, or the crown is repaired or remade. The implant itself is usually fine. 2. **Peri-implant mucositis** (bleeding without bone loss): professional cleaning, better home cleaning and sometimes reshaping the crown so it can be cleaned. This stage is usually reversible. 3. **Peri-implantitis** (inflammation with bone loss): deeper non-surgical cleaning, antiseptics and sometimes antibiotics, and if needed surgical cleaning of the implant surface, with or without bone regeneration. Results vary, and long-term maintenance is essential. 4. **A failed implant** (the implant moves or bone loss is too advanced): the implant is removed, the site is allowed to heal, often with a bone graft, and in many cases a new implant can be placed later. If not, a bridge or denture is an alternative. ## What should you do if you think your implant is failing? 1. Do not wait for it to hurt; bleeding or a bad taste is reason enough to book a check. 2. Avoid chewing on the implant if it feels loose. 3. Keep cleaning gently around it rather than avoiding the area. 4. Find your implant card or records (brand, size, date). This helps identify compatible parts. 5. Have an X-ray taken to check the bone level. 6. If you are unsure about the advice you received, a second opinion is reasonable. Seek urgent care the same day if swelling spreads towards the eye or neck, or if you have a fever or difficulty swallowing. ### Who is more at risk of implant failure? - Smokers, especially heavy smokers. - People with diabetes that is not well controlled. - People with a history of severe gum disease (periodontitis). - People who grind or clench their teeth without a night guard. - People who have had radiotherapy to the jaw. - Anyone who skips professional cleaning and check-ups. Knowing your risks before treatment is part of good planning; our page on [dental implant risks and disadvantages](https://elnabidentalclinic.com/en/faq/dental-implant-disadvantages-risks/) covers how they are reduced. ## A second opinion on a failing implant with Prof. Nouran A failing implant is stressful: you have already invested time and money, and you may not know whether to trust the advice you were given.
