Novocaine is a short-acting, local anaesthetic often used by a dentist to numb an area prior to a dental procedure on your teeth.
Top tips:
– It begins to work in around 5 minutes.
– Numbness in the area can last up to an hour.
– It wears off gradually with numb lips and tongue making drinking and speaking difficult.
Novocaine is considered to be a safe, local anaesthetic and your dentist will match the dose to your individual circumstances.
“People undergoing a medical or dental procedure should discuss their questions and concerns with their doctor or dentist.”
