What are the risks and complications of a local anaesthetic during a dental procedure?
This procedure may require a local anaesthetic. Damage to lips and cheeks – you may bite or rub the numbed area without realising the damage you are causing. Children may need to be supervised until the numbness has worn off.
Failure of local anaesthetic – this may require a further injection of anaesthetic or a different method of anaesthesia to be used.
Bruising – if you take any drug used to thin your blood, you are more likely to get a bruise as this medication may affect the way your body clots your blood. Applying a cold pack to the area will help to minimise the bruising.
Nerve damage – if nerve damage happens, it is usually temporary and will get better over a period of weeks to months. Damage may cause weakness and/or numbness of the mouth, lips, tongue or face that the nerve goes to. Permanent nerve damage rarely happens.
Infection at site of injection – this is uncommon however can be treated with antibiotics.
Allergy to the local anaesthetic solution – is a rare complication and medical attention should be sought immediately.
