Is it safe to blow dust off a motherboard with my mouth?

My motherboard is a bit dusty so I decided to just blow it with my dry mouth and the dust will just go away. My concern is will it create ESD? I know that the best way is to use air can duster but i don't think it worth using/buying it for a little amount of dust.
 
Solution
ESD requires physical contact between the cleaning tool & component, so no risk involved by blowing.
But it's an inadequate method, buy a can of compressed air like 5-Star from Amazon:

Give the entire interior of a case a good blast every few months, paying particular attention to heat-sinks, fans and cooling vents.

I just use a clean and soft dry paint brush, been doing it for years without any issues.
 
Come on - compress air cans for electronics are cheap and safe. Beside you can use it for other things like keyboards and electric razors. I certainly wouldn't use a paint brush. Under low humidity conditions it's possible to build up a static charge on it.

Get real.

If you have the breath to blow away dust collected on a motherboard and are willing to relocate to Turkey, we can open a 'spirirual healing' business by labeling you as 'a hodja with powerful breath'.

If you ever some form of compressed air ( using an 800 W air blower for example ) into your case, you will know what I mean.
