Welcome @chayre, From what I've read, numbness on one side of the face can be serious.

"Why is half my face numb?
Facial numbness can be alarming. It's a symptom that can occur with neurological problems that affect the brain or the trigeminal nerve (the nerve that controls sensations of the face). It can also happen with dental or mouth problems, after facial trauma, or as an effect of medications or toxins."
