There really is no end to it.
Just went to the dentist to fill up a cavity, and THREE more pops up.
It seriously pisses me off when I have been following the dentist's every freakin advice, have probably the most convoluted teeth brushing regime in the world and STILL get endless cavities.

Fine, I know my teeth are really lousy.
But I really could do without the dentist shovelling more shit at me.

First visit:
Dentist: (hands me tiny brush, points to teeth on the right) You put toothpaste on it and stick it between this two teeth like this everytime you brush your teeth.
Me: OK.

Second visit
(After lunchtime)
Dentist: I see food stuck there!! You HAVENT BEEN BRUSHING BETWEEN THE TWO TEETH LIKE I TOLD YOU TO!!
Me: Erm... Wasn't I suppose to use the brush only when I brush my teeth?
Dentist: NO! You are suppose to carry the brush with you at all times and use it everytime after you eat anything.
Me: ... Oh OK..

Third visit:
Me: I think I have a cavity between my two front teeth...
Dentist: (checks teeth) YOU HAVEN'T BEEN USING THE BRUSH I GAVE YOU!!! YOU ARE NOT BRUSHING YOUR TEETH.
Me: ...but...
Dentist: You were suppose to brush between every tooth! WHY DIDN"T YOU FOLLOW MY INSTRUCTIONS?
Me: ... ...

Why didn't I follow your instructions?
Well geez I don't know.
Could it be because I'm not a fucking mind reader??

And it REALLY makes my blood boil to hear the dentist muttering that she knew I had cavities which are now really deep 'cause I haven't been following her instructions.
Because if she knew I had cavities,
WHY THE HELL DIDN'T SHE FILL THEM UP IN THE FIRST PLACE???
Why did she tell me to go back for a checkup one year later when the cavities have gotten a lot worse AND THEN accuse me of not brushing my teeth?

She didn't even realise how bad the cavities got.
I had to tell her about them.

And it doesn't help that during the span of my 30 minute wait, the dental assistant tries to sell me a sweater, a second hand Blackberry PDA AND a secondhand handphone.
