My brother's dentist did something with his teeth that are on the left of the two front teeth(upper rwo), now when he tries to smile or laugh, his upper lip goes up from a side and this makes him look a bit funny, even if not, we can't help laughing cause thats not usual way he laughed or smiled.
Please explain if it is a normal reaction of filling teeth and repairng them?
My mom is getting it kind of supersticiously.
