Students working on my teeth? Depends. I trust the international students.... e.g. those who have a doctorate degree from another country and has to repeat two years before graduating. There are some exceptional students that stand out more so than others. The majority are..... shall we say.... dicey. They're not exactly experienced enough to know what they're doing. They are taught the theoretical aspects of a procedure then unleashed to unsuspecting patients.
Why hesistant about whitening? You're putting bleach on your teeth. Anytime you introduced a foreign substance to organic matter, it's not a good thing but right now, I want my teeth pearly white. They make you look younger.
