Hi Fitz. I'm sorry you're so worried. I hope this gives you some peace.
No, it isn't nearly as dangerous as brain surgery. It's more comparable to tooth extraction surgery. There's just a bit more as they "install" the implants.
No, it won't ruin your facial structure. If your dentist/orthodontist does anything, he'll improve any misalignments you may have. You'll look better, if it's necessary! If realigning your mouth is the plan, he will first discuss how best to do so.
A friend of ours got implants. He LOVES them! So many people suffer from ill-fitting dentures. They have mouth sores, and speech issues such as lisping. That doesn't happen with implants. He had nothing but praise for the results.
You can talk to your dentist about your fears. Ask questions about what to expect. Dentists don't mind these questions. TONS of people have these exact same concerns! You are normal to feel anxious. Calming your fears with knowledge is a regular part of your dentist's day.
I wish you peace, health and a beautiful smile.
