Interesting Case Study on Aluminum Foil

Interesting case study on aluminum foil:

If your teeth have been accidentally damaged in the past and have undergone dental surgery to repair them, and the doctor has inserted metal or something into your mouth, such as fillers or dental crowns, then you need to pay attention. Less than ten thousand

Well, in fact, there are no such critical situations in real life, haha. Don't use your teeth to bite on cable foil or other aluminum foil, because once you bite, your teeth and your entire mouth will feel a tingling sensation

The pain sensation! Why... blame the aluminum foil. Because you have a metal attached to your mouth or teeth by a doctor, with some having gold inlay and others having silver inlay, and aluminum foil being another metal, and your mouth is filled with saliva containing salt, a battery is formed here. Battery! That's right, it's the battery. A current flows through the nerve endings of your teeth. Do you think it stimulates them? Is it sour and refreshing? Specific process: At the moment when the teeth bite down, the two different metals in the mouth make full and extensive contact in the moist, lubricated, and salt filled saliva; Because there is a potential difference between two different metals, electrons run from the aluminum foil to the teeth, forming an electric current; Then, the current quickly excited the root nerves.
