As the people’s oral hygiene becomes better, generation after generation, people are going to need less dental treatments. This is a very good thing! But for those who occasionally need a small filling, or other treatment, they might apprehend the “needle” they will receive at the beginning of their appointment.
What should you expect from dental anaesthesia?
First your dentist will inject you with the anaesthetic solution. Most dentists apply a spray or gel first, to numb the area of the injection so you could feel less the needle. Each person has a different perception of pain, therefore the injection might be completely painless, or cause some discomfort or mild pain. Then when it kicks in, you will feel tingling at the numbed area.
Depending of which tooth needs to be anaesthetized, sometimes the numbing sensation can affect only that tooth, or it could be a whole section of your mouth. The neighbouring lip, tongue, cheek, or even nose can also get numb.
Today’s anaesthetics are very good, but not always efficient from one injection. If you feel pain when your dentist starts working, it is important to advise him or her. Sometimes more injections are needed.
There are different types of anaesthetic solutions. Some last a few moments, where others last several hours. The choice is made by your dentist depending on your health, and the type of treatment that is planned.
When the anaesthesia wears off, you will feel tingling and then your mouth will be normal. You might feel pain at the injection site for a few days.
Very rarely someone can have the numbing effect last a few days or a few months. This is called paresthesia. But there are no documented cases where paresthesia lasted throughout someone’s life just from the injection.
