My bathroom sink off my bedroom smells like sewer gas when I turn the water on and then dissipates. The sink has a "P" trap and is used many times a day. What could be causing this problem ?.
Clean/dump out the trap and put it back together. Shine a light down through the sink drain and make sure that it is clean down to the trap.

Check for odors around your toilet too. A bad wax seal will let in sewer gas.

Bad design or a clogged vent could cause the water to siphon out of the P-trap. S-traps were notorious for this which is why they're no longer used.

Mix up a bleach solution and pour it in the drain and also down through the overflow.
This is sometimes hard to accomplish because of the location and the way porcelain sinks are made. Make a cup out of your hand in front of the hole and flood it in there pretty fast.
If the whole body of the sink is hollow you may have to figure out a way to squirt it around in there.
Or, you could have a vent problem...maybe add a Studor Vent?
