In recent years, dental implants have emerged as a preferred method for replacing damaged or lost teeth. This trend is due to the high quality, healthy method, and long-lasting results of dental implants.
With proper care, many dental implants can last a lifetime. Though dental implant failure is uncommon (with a success rate of over 94% in most cases), failures can still occur. However, it's important to note that implant failure is not due to any bodily rejection, as the body doesn't produce antibodies or antigens against the implants like it would in other surgeries. The body doesn't react to dental implants as foreign material.
Top Three Reasons for Dental Implant Failure
1. Failure in Osseointegration
This occurs when the implant loosens and falls out. After implantation, it takes several months for natural osseointegration, which is when the implant fuses with the jawbone. In some cases, the bone doesn't fuse properly, leading to implant failure. Osseointegration failure can result from improper positioning, low bone density, damaged or unhealthy surrounding tissue, overloading, or trauma.
2. Damaged Nerves or Tissues
If implants are placed too close to a nerve, it can cause intense pain, which may radiate in any direction of the jaw. Nerve damage may also result in tingling sensations or numbness in the gums, tongue, lips, cheeks, or chin. Depending on the severity, the nerve damage could be temporary or permanent, but the implant will need to be removed. This type of failure often occurs due to lack of experience from the dentist.
3. Poor Dental Hygiene
Improper oral hygiene after surgery can lead to gum infections or bone loss, contributing to implant failure. Ensuring proper dental care, particularly after surgery, is critical for the implant's success.
Signs of Dental Implant Failure
- Pain in the gums or below the implanted tooth
- Discomfort around the implants
- Inflammation of gums or surrounding tissues
- Numbness or tingling sensation
- Unusual bleeding
The best way to prevent implant failure is to follow your dentist's instructions, maintain excellent oral hygiene, and brush and floss your teeth at least twice daily. Additionally, using an alcohol-free antibacterial mouthwash can help maintain oral health.
