Colgate Total teeth@gum scan??!!

1. salam..i have one thought regarding the commercial..i couldnt find the commercial for colgate total in malaysia but the commercial above is almost the same, only the language is different

2. so..can the scanner really2 scan the teeth and gum for bacteria?
as we know, oral commensal include staph, strep, neisseria, and other fungal and also virus. lets put aside virus first cause it is realy2 small compare to bacteria..so we try to look into bact. first okes?

3. bacteria is very small that only microscope can see it..even though microscope can see it, we still need special staining to look at it because some of it is gram negative while some are gram positive..so can really the scanner look at it?

4. first i thought the scanner is to detect the teeth stain or plague. but then i realized that the commercial specifically said bout bacteria buildup and also it has some scale from low to high germ density!!wow..i dunno what scale they use because the microbiologist use the petri dish and use the colony of bacteria to calculate things related to the amount of bacteria..

5. so if somebody there can explain this further to me i am really grateful..i already send an email regarding this matter to the colgate but i dun think i will get any respond from them..haha tq
