Most wisdom tooth extractions are carried out successfully with no issues, but your dentist should still talk to you about any risk of nerve damage before you agree to the procedure.
Your dentist should ensure that you’re aware of any potential risks in relation to the treatment they carry out, so that you understand what the potential consequences could be.
If you do suffer long-term or even permanent nerve damage from wisdom tooth extraction, it doesn’t necessarily mean that your dentist was negligent in their care. However, if they didn’t make you aware of the risks and side effects before the procedure was carried out, you might be eligible to claim compensation.
