Can root canal anaesthesia side effects
Local anaesthetic can cause temporary numbness and tenderness, while reactions depend on the drug, dose and patient.
The short answer
Local anaesthetic for a root canal most often causes temporary numbness near the injection site; the dentist considers dose and medical history.
What is the direct answer?
What does this question mean?
The solution is placed near nerves supplying the tooth. Soft-tissue biting, injection soreness, dizziness or a brief racing heartbeat can occur.
What can you do next?
Tell the dentist about allergies, pregnancy, heart rhythm problems and medicines. Avoid biting numb tissue until sensation returns.
When should you seek dental care?
Contact the dental team if numbness lasts unusually long or symptoms worsen. Breathing difficulty or fainting is an emergency.
What should you ask the dentist?
Ask which anaesthetic is planned, whether a vasoconstrictor is included and how long numbness should last.
