When done correctly, dental implants can last a lifetime. They’re one of the most effective and natural-looking solutions for replacing missing teeth. But here’s the part most people don’t tell you: dental implants can—and sometimes do—fail.
At Lobb Dental in Edmonton, we believe that patients deserve to know both the benefits and the risks associated with a decision before making it. That’s why Dr. Lobb takes time to explain how dental implants work, what could go wrong, and how to set yourself up for success.
In this article, we’re pulling back the curtain on the 7 most common reasons dental implants fail—and what you can do to prevent them.
1. Poor Bone Quality or Quantity
One of the most common reasons dental implants fail is insufficient bone density. Your jawbone needs to be thick and strong enough to support the implant post. If the bone is too thin or has deteriorated due to tooth loss or gum disease, the implant may not stay secure.
At Lobb Dental, we always perform a detailed bone assessment using advanced imaging technology before proceeding with implants. If the bone isn’t ready, there are solutions like bone grafting to strengthen the area.
This leads us to another important factor in implant success—the skill and experience of the person placing them.
2. Inexperienced Placement
Dental implants are a surgical procedure, not just a cosmetic one. While many general dentists offer implants today, the experience of your provider makes a huge difference. Improper placement can lead to nerve damage, sinus issues, or implant instability—problems that could have been avoided with careful planning and consideration.
Dr. Lobb has extensive training in implant dentistry, ensuring precise placement. This kind of precision reduces complications and improves long-term success.
Of course, even a perfectly placed implant can fail if a patient’s habits get in the way—which brings us to lifestyle choices.
3. Smoking and Lifestyle Habits
Smoking is one of the leading causes of dental implant failure. Nicotine restricts blood flow, making it harder for your body to heal after surgery. This slows down the osseointegration process—when the implant fuses to the bone—and can increase the risk of infection.
At Lobb Dental, we strongly recommend quitting smoking before and after implant surgery. We also advise patients to address habits like teeth grinding, which can place extra stress on the implant. Making healthy lifestyle choices is one of the easiest ways to protect your investment.
However, even non-smokers face risks if post-surgical care isn’t handled properly, which leads to infection.
4. Infection After Surgery (Peri-Implantitis)
Peri-implantitis is a severe infection that affects the tissue around an implant. It often begins with poor oral hygiene, allowing bacteria to accumulate around the implant site. If left untreated, it can lead to bone loss and implant failure.
That’s why Dr. Lobb provides every implant patient with a customized care plan, including hygiene tips and follow-up appointments to ensure optimal care. Regular cleanings and check-ups are crucial for detecting potential problems early.
But infection isn’t the only technical challenge to consider—sometimes, failure starts with the planning stage itself.
5. Poor Implant Placement
Dental implants aren’t just about drilling and placing a post. Proper planning is essential to avoid hitting nerves, sinuses, or placing the implant in an unstable position. Unfortunately, some providers rush this step or rely on outdated methods.
At Lobb Dental, we strive to prevent complications and ensure the implant is placed in the safest and most supportive location. Even so, medical conditions can sometimes complicate the healing process—another factor patients should be aware of.
6. Medical Conditions That Affect Healing
Certain health conditions can increase the risk of implant failure. For example, uncontrolled diabetes, autoimmune disorders, or osteoporosis can slow down healing or interfere with bone integration. Even medications like bisphosphonates (used for bone loss) may affect implant success.
That’s why Dr. Lobb conducts a thorough review of a patient’s health history before recommending implants. We’ll work closely with your physician if needed to ensure your body is ready for surgery. Managing your overall health is just as important as managing your dental care.
Still, even if all the medical boxes are checked, there’s one more reason implants can fail—misaligned expectations and lack of follow-up care.
7. Unrealistic Expectations and Poor Follow-Up
Some patients believe that once an implant is placed, it’s a “set it and forget it” solution. But like natural teeth, implants require ongoing care and maintenance. Neglecting this step can lead to gum problems, bone loss, and eventual implant failure.
At Lobb Dental, we prioritize patient education so you know exactly what to expect. We guide you through the entire process—from surgery to recovery and long-term maintenance—so you have no surprises. When patients follow our recommendations, the success rate of implants remains incredibly high.
