how far down the throat do you clean your tongue?

[cool]

i always clean my tongue with a special tongue cleaner.
now i took a little mirror and tried to look down my throat and i saw some coatings on the end of my tongue that i cant reach with my oral hygiene standart.

so my question is: how far down the throat do you clean your tongue?
do you really clean the whole tongue or just the parts you can see or reach?

whats your method?

[trouble]

i clean the tonge as far as i can reach with my index finger (thats pretty far). i take such a soft cleaning device, which is for babies and you can slip in with your finger. otherwise just a cloth.

i took a dentist mirror to take a look to the end of my tongue.
there still was a lil coating thats why i started to bother.
i cleaned the area with almost the same utility as (went to the pharmacy, feeling like mcgyer buying tsuff like raw patches or plasters and else to pull over my index finger to reach that level of tongue)

that coating didnt smell like sh!t but wasnt odorless.

but i wonder if this coating is normal or maybe indicates some candida fungus or yeast problems in the intestinal or whatever.

although im not sure if i have bb at all, after cleaning this area with miradent tongue-clin gel i was able to talk to others pretty close for some hours.
