After revisiting one of my favorite online video games from my childhood, Dental Adventure, I've decided to go to both YouTube and a few online archives of the game and rip the games soundtrack for y'all to listen to and enjoy.
This particular track that you're hearing is the default gameplay theme. In case the radio isn't playing in the dentist's office (it's there so you can sooth the patient with his/her preference of music genre as you're cleaning his/her teeth), this'll be the default music that plays in the background as you're cleaning your patient's teeth (like a good dentist should).
You may only use this piece for commercial purposes if your work is a web-based game or animation, otherwise you must make specific arrangements with the artist.
