With this kit you can buy nothing wrong, everything attached you need for your teeth. Once work on the rough and then the tooth gaps. Could my tartar completely perfect and easy to remove and my teeth look again great. With the mirror, it is ne conversion, but because you have to work in the opposite direction that I had to get out quickly. Would highly recommend it, and the shipping was very fast also. This set is very stable and can withstand a lot, like the dentist.
