What did the Dentist put on my tooth? (My Dentist story)?

He put some sort of he said 'Cleaning liquid' on the tooth of mine that had a lot of the white stuff(plaque i guess) What does this do? and what's it called? Anyway i would just like to say if anyone is scared of getting a filling for the first time its not even anything to worry about to be honest, i personally get scared anyway even though i KNOW it's nothing serious and nothing is going to happen nor is anything going to hurt i just randomly get scared and become close to peeing myself even though i go the toilet before i leave the house (lol) I didn't take any ipods or anything with me usually i just stare up at the ceiling lol everytime i get into the dentist chair my legs REALLY shake like crazy which is annoying lol yet i don't seem to feel scared which is weird.. but anyway its nothing to worry about at all if your getting a filling (don't know about anything else) my first time it took about 30 minutes didn't feel anything at all not even the needle. second time i actually went today for my second filling and he done it in like 5 minutes and when he said ok your good to go i was like wtf? O_o loool he used a different needle this time ( duno why but if anyone could tell me that would be cool) this time i felt a tiny pinch but it was nothing at all i was sitting there like ........., some people think the drill hurts but it doesn't when you get numbed you don't feel anything lol the only annoying thing with the drill is that when the dentist is drilling water allways comes out and lands in my eye lol so it's probably best to close your eyes :P make sure you eat quite a bit of food before you go aswell i would say because i didn't do that today and i just got home and i'm starving and nowhere near the point of my numbness wearing off and i don't want to eat anything just incase not even on the other side of my mouth. it feels like you have big lips and a big balloon inside of your mouth but your face actually looks normal at the end when he had finished i asked him i'm just wondering what mouthwash do you recommend and he said i don't recommend any mouthwash just the regular brushing teeth so i hope that helps someone in deciding what mouthwash to get, obviously he knows best so i'm going to follow him i didn't like the sound of mouthwashes anyway due to the alcohol content but overall anyway it was fine i had no pain just annoying shaking in my legs and water splashing in my eyes from the drilling, and starvation after because i can't eat so make sure ya eat somethin! ): I know your probably thinking why did he post this but i just felt like telling people what happened on my first time and second time hopefully this will calm some minds down. Can't wait to eat some food how about sharing your dentist stories they mite be more interesting to read than mine just the typical visit of mine. Bye (': xx
