Visit to the dentist

i went to the dentist's office yesterday to see the oral hygienist in order to get my teeth cleaned. when i got there, i was told to lie down and relaxed then the hygienist checked the xtray i had done weeks before to see if everything was ok in there. next thing she brings out all those dental instruments and my heart just started pumping real fast. she checked my gum and then started counting for some reason i was like this wayo people have started again then she says. " you have a gum disease and i am sure that you must have notice that whenever you brush your teeth, your gum bleeds. i had to think for a while and it got me all confused. she said the disease was still at it's early stage; therefore. in order to prevent the disease from getting serious and having loose teeth i had to do some form of serious cleaning. in my head, i was like this is scary, guess she read my mind then told me that it was going to be simple that i wont feel any pain since i was going to be given lidocane. so i told her okay no problem. then she says well if you insurance will pay you can make use of laughing gas or valuim but i will be sore after the process and that i had to bring an excort along for the process. so i told her ok no problem. to verify, she went to bring another dentist that everything was going to be ok. well i scheduled an appointment for the following week even though i knew i was never going back to them (well maybe to go fill that one tooth they refuse to fill except they did the serious teeth cleaning).
anyways to cut the long story short, immediately i got home, i ran into the bathroom to brush my teeth just to see if the imaginary bllood the dentist was talking about was going to come out. abegi no redish thing came out except the toothpaste so can someone tell me what the hygienist was talking about?
