You may only need to wear it at night, but it will allow your tooth to tighten up on its own in these cases. If you have gum disease, then you will likely need a deep cleaning. Since gum disease creates pockets of bacteria and infection between the tooth and gum itself, this can lead to loose teeth. By cleaning the gums and removing these pockets, your gums will become healthier and they will tighten up on the teeth again.
The next step for surface mount led soldering to a circuit board is the manual reflow process. With one hand, you must reflow, or heat up the solder on the circuit board pad (where previously applied). As you re-heat this solder, slide the LED onto the center of the pads with your opposite hand.
If this circuit didn't have a transistor to amplify the current, the LED would not light. However, with the transistor and the amplification it provides, the current is amplified large enough to light the LED. This is how it works: -The small current travels from the voltage source into the base of the transistor.
