As the others have mentioned, get in to see another dentist and hygienist. This way you can be sure that you didn't already do damage to your teeth while removing the braces at home. It's a good idea to start out with a professional cleaning anyway because many kids aren't super-careful about their dental routine while wearing braces.
As Amir said, it shouldn't be too expensive and you'll avoid damaging your enamel.
WOW- removed your own braces...
