We all can be someone's superhero, and Brazilian dentist, Felipe Rossi is the perfect example of exactly that.

Dr. Rossi founded the 'NGO Por1sorriso' charity to provide free dental work to low-income individuals, and he and his colleagues have been traveling the world doing just that.

Felipe and his team have been restoring the smiles of some of the poorest people on the planet, completely free of charge, and we have some of the most inspiring before and after photos to share with you. Some of these pictures are truly heartwarming, and it's easy to see just how significant dental work can be in helping to restore a person's confidence and sense of self-esteem.

Scroll down and get ready to smile (and perhaps shed a tear or two) at these amazing transformations!

In an interview with Bored Panda, Terri Rimmer told her story about getting her teeth fixed. “Before surgery, my life was just a black hole. I spent years not being able to smile in pictures and it was always humiliating because people taking pictures in a group setting kept saying, ‘smile’ and I couldn't do it,” Terri said. “Also I had to give up so many things that I couldn't eat that I loved for years like fresh cherries and salads. I hadn't had a salad in 18 years! After surgery, I can smile in pictures and I have confidence! When I put my dentures in for the first time and went into the bathroom at the dentist I just kept looking at myself in the mirror and smiling. It was like my face was plugged in after all these years! My eyes just lit up and my face was just lifted! Even my mom and other people noticed.”

Terri explained that her dental condition was so extreme that all of her teeth had to be removed: “I had no bone at all in my upper jaw, so they had to borrow bone from a cadaver. They had to remove the top teeth first, which there were only a few of and the recovery from that was excruciating."

“I was in pain for two weeks. The bottom area – the recovery was much smoother but it took me several months to fully recover. It was painful but very worth it! They had to give me four shots in the roof of my mouth and take four wax molds of my mouth. I cried hysterically because it was so painful. The pain medication I was prescribed after surgery upset my stomach too bad so I had to quit taking it. I had an extremely hard time. They put four screws in my mouth and four implants before they could make my dentures.”

“I would like people to understand that how I wound up losing all my teeth was from extreme depression after my boyfriend died of cancer in 2005. I stopped brushing my teeth and though I was on 5 medications for depression and anxiety, it wasn't enough.”

Thankfully, things are now much better for Terri. “People definitely greet me warmly and want to interact with me more so than when I didn't have any teeth.”
