I just had dental work at the top of mouth and my smile is crooked. i've never had this happen. will it stay that way? please help

No: I assume you had local anesthetic. It can take hours to wear off. In the very , very unlikely event a nerve was actually damage during injection, it will also heal back to normal.

Temporary numbness: It is normal condition. Your lips teeth and tongue may be numb for several hours after the dental treatment appointment. Avoid any chewing until the numbness has completely worn off, preventing biting yourself. Good luck.

Without: Without seeing you and doing a comprehensive examination, and also examining your pre-treatment records, there's no way to comment on what was done and why. If you are dissatisfied with the results of your treatment, discuss your concerns with your treating Dentist or seek a qualified second opinion.
