Why does your anaesthetist look in your mouth?

If you are getting ready for surgery, you might be surprised when your anaesthetist asks to take a quick look inside your mouth. It can feel a little random, but this simple check is actually a crucial part of keeping you safe.

When you are under general anaesthesia, your body relaxes completely—including the muscles that keep your airways open. To make sure you breathe smoothly and safely while you are asleep, your anaesthetist will usually need to place a breathing tube into your throat after you are fully unconscious.

To do this smoothly, they need to map out the territory beforehand. By checking your teeth, jaw movement, and the shape of your mouth, they can figure out the easiest and safest way to manage your airway. For instance, they will look out for loose teeth, crowns, or caps so they can take extra care not to damage them when placing or removing the tube.

It is all about preparation. Taking a peek at your smile helps your medical team customize your care, anticipate any challenges, and ensure you wake up safe, sound, and with everything just as it should be.
