Dental implants are one of the most successful and life-changing treatments in modern dentistry—but like any medical procedure, they come with potential risks. While implant success rates are high, it’s important to understand possible complications, how to prevent them, and what to expect if something goes wrong.
At Laguna Heights Dental in Laguna Niguel, CA, Dr. Nazita Gaff combines advanced technology with years of experience to minimize risks and ensure long-term success for every dental implant patient. Here’s what you need to know about implant complications, and how we help you avoid them.
What Are Dental Implant Complications?
Dental implants are typically safe and predictable, with a 95–98% success rate. However, complications can occasionally occur—sometimes shortly after placement, or years down the line. Being informed can help you take the right steps early.
Common Dental Implant Complications & How to Manage Them
1. Infection at the Implant Site (Peri-Implantitis)
What it is:
An infection in the gum or bone around the implant—similar to gum disease.
Signs:
✔ Red, swollen, or bleeding gums around the implant
✔ Bad breath or taste
✔ Bone loss visible on X-rays
Prevention & Treatment:
✔ Maintain excellent oral hygiene
✔ Attend regular cleanings and checkups
✔ In early stages, a deep cleaning and antibiotics may help
✔ In advanced cases, laser therapy or surgical intervention may be needed
2. Implant Loosening or Failure to Integrate (Osseointegration Failure)
What it is:
When the implant doesn’t fully bond to the jawbone.
Causes:
✔ Poor bone quality or density
✔ Smoking
✔ Excessive pressure on the implant before healing
Prevention & Treatment:
✔ 3D imaging to assess bone quality beforehand
✔ Following post-op care instructions
✔ In some cases, the implant may be removed, the area allowed to heal, and a new implant placed successfully later
3. Nerve or Tissue Damage
What it is:
Occasionally, an implant placed too close to a nerve can cause numbness, tingling, or pain in the lips, chin, or tongue.
Causes:
✔ Improper implant placement
✔ Lack of digital imaging or planning
Prevention & Treatment:
✔ We use advanced 3D CBCT scans to map out exact implant locations
✔ Most cases are temporary and improve over time
✔ In rare cases, removal or repositioning of the implant may be necessary
4. Sinus Complications (Upper Jaw Implants)
What it is:
For implants placed in the upper jaw near the sinus cavity, there’s a risk of sinus perforation.
Symptoms:
✔ Sinus pressure or infection
✔ Implant loosening or discomfort
Prevention & Treatment:
✔ Use of sinus lift procedures when necessary
✔ Proper planning and imaging
✔ Most sinus complications can be resolved with minor surgical correction
5. Implant Fracture or Mechanical Failure
What it is:
A rare issue where the implant post or attached restoration (crown, bridge, denture) breaks due to excessive force.
Causes:
✔ Grinding or clenching (bruxism)
✔ Poor bite alignment
✔ Trauma
Prevention & Treatment:
✔ Use of nightguards if you grind your teeth
✔ Stronger materials and bite adjustments
✔ Replacement of the damaged implant or crown

What to Watch for After Dental Implant Surgery
Here are signs you should contact your dentist immediately:
- Persistent pain after a few days
- Bleeding that won’t stop

- Loosening or shifting of your implant
- Numbness or tingling that doesn’t go away
Catching these issues early can make treatment simpler and prevent bigger problems.
