A chainsaw's chain should be fitted so that the points of the teeth face in the same direction as the chain moves. Then they will cut into the wood without needing much downward pressure.
If the teeth are sharp you should never have to force the chain down into the surface of the wood.
If you find you have to force the chain down to make it cut the wood then the teeth must either have gone blunt - and the chain needs to be sharpened or replaced - or the chain was installed with the teeth facing the wrong way so that the backs of the teeth just rub over the surface of the wood and you need to press down very hard just to get the teeth to wear down into the wood instead of cutting it cleanly.

I'm no expert, but i would think that, unless you don't care about your teeth, teenagers should brush their teeth the same way everyone else should.
The blade is places so teeth cut on the push stroke.

My 4 year old niece fell hard on the ground and hit her face. When she got up she was bleeding from her gum right over her 2 upper front teeth. She keeps saying her teeth are hurting but I'm not sure if she really means teeth or she just doesn't know the difference between teeth and gum but either way should this be something to worry about? Her teeth seem normal though, just some tumering from the fall. What should be done in such case before considering taking her to a doctor/dentist?
Start the saw without the blade for a split second to see which direction it spins. The saw blade teeth should point in the same direction. The points of the teeth are the part that should strike the wood first.
Either way
The same way he talks to you face-to-face. And politely.
not really you should do it face to face or by email
Yes, you can have four teeth removed at once. Wisdom teeth are done this way to quicken the recovery time of doing two, then two again.
No I don't. But my ear doesn't have bottom teeth. Should I be worried?
