Dental implants are known for being highly reliable and successful, but like any dental treatment, there’s a small chance things may not go as planned. While implant failure is uncommon, it can happen—and if it does, there’s no reason to panic. The key is knowing the signs that your implant may need a closer look.
A typical dental implant is made up of three key components:
If any one of these parts becomes loose, damaged, or fails to function properly, complications can arise.
Although implants are made from durable metal, their success depends on a natural biological process called osseointegration. This occurs when the jawbone grows new bone cells that fuse tightly to the implant’s surface, securing it in place. Over time, this bond allows the implant to function just like a natural tooth root. However, if osseointegration does not occur as expected, it may lead to issues after the implant is placed.
When an implant does not properly bond with the surrounding bone, one of the first and most common warning signs is mobility. In the early stages, this movement may be so minimal that only a dentist can detect it. Over time, however, the implant may begin to feel loose or wobbly, especially when chewing or speaking. Unlike a natural tooth, a failed implant will remain consistently movable.
Other possible indicators of implant failure can include pain, swelling, or infection, though these symptoms are not always present. To confirm what’s happening beneath the surface, your dentist may recommend an X-ray. In cases of failed osseointegration, the X-ray often reveals noticeable bone loss around the implant.
While dental implants are generally very successful, certain health conditions, lifestyle habits, and medications can increase the risk of complications. Some of the most common factors include:
Certain medications may also play a role. For example, research from the University at Buffalo suggests that compounds in some antidepressants can affect bone metabolism, potentially interfering with osseointegration.
Additionally, smoking has been shown to increase the risk of implant failure. A study published in the Journal of Dental Research notes that the implant’s location in the mouth can influence how strongly smoking impacts success rates. Many dentists recommend quitting smoking altogether or, at the very least, avoiding it until the implant has fully integrated with the bone.
The reassuring news is that a failed dental implant can usually be removed easily under local anesthesia. If the surrounding bone remains healthy and intact, you may not need any additional procedures before a new implant is placed.
However, if bone loss has occurred, your dentist may recommend a bone graft to rebuild and strengthen the area. This graft will need time to heal fully before another implant can be placed.
During this healing period, your dentist will also work with you to address any factors that may have contributed to the implant failure—such as quitting smoking, managing teeth grinding, or postponing implant placement until after certain medical treatments. Taking these steps can improve the chances of long-term success with your replacement implant.
Before moving forward with implant treatment, it’s important to talk with your dentist about any medical conditions or medications that could affect healing and osseointegration. Even after your implant is placed, be sure to keep your dental team updated about any changes in your health, as these may impact your recovery and long-term success.
Practicing excellent oral hygiene is also essential. Brushing at least twice a day and using an antibacterial mouthwash can help protect your gums, reduce harmful bacteria, and support the healing process while your implant integrates with the bone.
