Dental implants can cause nerve damage, warns study

Dentists are not being vigilant when carrying out implant surgery and are failing to inform patients about the risks of nerve damage, a study in the British Dental Journal says.

Researchers from King's College London Dental Institute analysed 30 patients with nerve injuries and found problems with pain, speech, eating and kissing.

Around 1% of implant procedures carried out each year result in nerve injuries. Dentists should improve care before and after implant surgery, the study says.

A dental implant is an artificial tooth root, which is screw or cylinder-shaped, that is placed into the jaw to hold a replacement tooth or bridge.

Dental implants are generally used if someone has lost a tooth or teeth due to disease or injury. The type of nerve injury which can be caused by implant surgery has increased in recent years alongside a rise in implant surgery.

Approximately 10,000 lower jaw implant procedures are performed each year in the UK. In 2007, 30% of all nerve injuries cause by dental work were associated with implants. This contrasts with 10% in 1997.

The King's College London research team found that these injuries could have a significant impact on people's quality of life. More than half of the 30 patients participating in the research suffered constant pain or discomfort after surgery, with 40% complaining of numbness.
