Bell's palsy. Can i get my smile back?

It's been 10year's m suffering from Bell's palsy. My parents don't know about this infection n they neglected this, they thought after few days m gonna be all right. And only getting physiotherapy sessions I got cured 75 percent. My parents gave up n didn't tried anything. In Decmber 2017 I got accupunture n that helped me alot. Actually m a fashion designer n for me my smile keeps me confident but some times it makes me sooo low dat I can't  consntrate on anything coz of hesitation dat I look ugly Wen I smile 😞 My confidence level is going low slowly. I just want to ask can v cure this? Can I get my smile back? If yes plz suggest wat I have to do. Pls pls pls it's an humble request any suggestions do reply. If der is no cure for dis I'll stop searching any cure for this
