Dental implants are widely recognised as a long-lasting and natural-looking solution for missing teeth. But like any surgical procedure, there are potential risks and complications. Understanding what these are—and how to prevent them—can significantly improve your implant success and satisfaction.
This guide outlines the most common dental implant complications and provides actionable advice to minimise your risk, all while staying compliant with UK private dental healthcare regulations.
Understanding Dental Implants – A Quick Refresher
What Are Dental Implants?
A dental implant is a small titanium post surgically placed into the jawbone to replace a missing tooth root. It’s topped with a custom crown, bridge, or denture to restore appearance and function.
Key components:
- Implant post – acts as the root
- Abutment – connects the post to the crown
- Crown – mimics the visible part of your tooth
Dental implants are known for their stability, comfort, and natural feel.
Success Rates and Longevity
Dental implants boast a 90–98% success rate, especially when placed by experienced professionals under strict clinical protocols. When cared for properly, implants can last 10–20 years or longer, making them one of the best long-term dental investments.
Most Common Dental Implant Complications
-
Infection at the Implant Site (Peri-Implantitis)
What it is:
A bacterial infection affecting the soft and hard tissues around the implant. It’s similar to gum disease and can lead to implant failure if untreated.
Causes:
- Poor oral hygiene
- Smoking
- Untreated gum disease before implant placement
Prevention:
- Maintain excellent oral hygiene
- Avoid smoking, especially during healing
- Ensure your dentist treats any existing gum issues beforehand
-
Implant Failure or Rejection
Early failure: Happens before osseointegration (when the implant bonds with the bone) is complete.
Late failure: Occurs months or years later, often due to infection, overload, or bone loss.
Risk factors:
- Smoking
- Uncontrolled diabetes
- Poor bone quality
- Lack of aftercare
Prevention:
- Thorough patient screening and medical history review
- Bone grafts if bone volume is insufficient
- Regular follow-ups during healing
-
Nerve or Tissue Damage
Symptoms:
- Tingling, numbness, or sharp pain in the lips, cheeks, gums, or tongue
Causes:
- Implant placement too close to a nerve
- Inadequate pre-surgical imaging
Prevention:
- Use of 3D imaging (CBCT scans) to precisely map nerves and bone
- Choosing a skilled, GDC-registered dental surgeon
-
Sinus Issues (for Upper Jaw Implants)
Problem:
When implants placed in the upper back jaw penetrate the sinus cavity, leading to infections or sinusitis.
Prevention:
- Thorough pre-treatment assessment using CBCT scans
- Sinus lift procedures to increase bone height when needed
-
Loose Implant or Loose Crown
Causes:
- Improper integration
- Uneven bite forces
- Teeth grinding (bruxism)
Prevention & Management:
- Custom-fit prosthetics
- Occlusion (bite) checks
- Night guards for patients with bruxism
-
Bone Loss Around the Implant
Causes:
- Infection
- Excessive force
- Poor oral hygiene
- Lack of follow-up care
Prevention:
- Maintain regular dental check-ups
- Gentle but thorough brushing and interdental cleaning
- Avoid biting on hard objects or using teeth as tools
How to Reduce Your Risk of Dental Implant Complications
Choose a Qualified, GDC-Registered Implant Dentist
In the UK, only dentists registered with the General Dental Council (GDC) are legally permitted to place dental implants. Ensure your provider:
- Has experience in implantology
- Works in a CQC-regulated private clinic
- Uses advanced diagnostics and sterile protocols
Follow a Comprehensive Treatment Plan
Your dentist should:
- Conduct full medical and dental history checks
- Use 3D imaging (CBCT) to plan implant placement
- Suggest bone grafting or sinus lifts when needed
These pre-treatment steps significantly reduce risk.
Maintain Excellent Oral Hygiene
- Brush twice a day using fluoride toothpaste
- Use interdental brushes or floss daily
- Attend routine hygiene appointments to remove plaque
Neglecting hygiene can lead to peri-implantitis and implant loss.
Attend All Follow-Up Appointments
Follow-up visits allow your dentist to:
- Monitor healing and integration
- Check for signs of inflammation or early failure
- Adjust bite pressure if needed
When to Contact Your Dentist About a Potential Complication
Red Flags to Watch Out For
Contact your dentist immediately if you notice:
- Persistent pain or throbbing at the implant site
- Loose-feeling implant or difficulty chewing
- Bleeding, swelling, or pus discharge
- Foul taste or odour near the implant
Importance of Early Intervention
Dental implants are highly predictable, but early intervention is key when complications arise. Delaying treatment could lead to:
- Loss of the implant
- Damage to surrounding teeth or bone
- Need for costly revision surgery
