Dental Crown Anaesthesia Explained

Why Anaesthesia Is Used for a Crown

A crown needs some of the tooth reshaped so the new restoration can fit properly. That preparation involves a drill and nobody wants to feel that without being numb. So your dentist uses anaesthesia to block pain signals from the area while you sit through the procedure.

You may still notice pressure. You might hear the drill too obviously.. The difference is that pressure and movement aren’t the same as pain and once the area is properly numb the actual preparation usually feels much less dramatic than people expect.

How Does Dental Anaesthesia Last?

Numbness doesn’t disappear the second the crown appointment ends. Your lip, cheek or tongue can stay numb for a hours depending on the anaesthetic used and where the injection was given.

During this period take care with eating and drinking. Biting a cheek is surprisingly easy because you don’t get the usual warning from your nerves.

Will You Feel Anything During Crown Preparation?

• Pressure around the tooth is normal especially while the dentist is shaping it.

• A quick sting from the injection then mostly numbness. The uncomfortable bit usually passes fast.

• Your cheek may feel thick. Swollen even though it isn’t actually swollen, which is a very odd sensation.

• Sharp pain during preparation isn’t something you should simply put up with. Tell the dentist more anaesthetic can be given.

Does Every Crown Need Anaesthesia?

For a living tooth though local anaesthesia is usually the sensible choice for crown preparation. It keeps the procedure comfortable. Lets the dentist work without you flinching at every sensation.

That matters more than people think. Once you’re numb the whole appointment can feel quicker because you’re no longer waiting for every drill sound to hurt.

What Happens After the Numbness Wears Off?

Some tenderness around the tooth or gum can happen after crown preparation. The tooth may also feel sensitive for a time particularly if the nerve is still alive. Mild sensitivity isn’t automatically a sign that something has gone wrong.

The anaesthetic itself is rarely the part worrying about. It’s simply there to get the sensation out of the way while your dentist prepares the tooth.. Once the numbness starts fading your mouth gradually feels like your mouth again.
