A 28-year-old male asked:

No, but...: Many things are possible in life. The chances of catching brain-eating amoeba from tap water in the U.S. is so unlikely that the answer is "no." If the water's chlorination or disinfection became inadequate, it's possible that Naegleria could survive in that water. The level of chlorination should remain high enough all the way to one's tap, as Naegleria cysts are somewhat resistant to chlorine.

Extraordinarily: unlikely. In June 2017 drinking water testing by the Louisiana Department of Health confirmed N. fowleri, in Ouachita Parish’s North Monroe Water System & Terrebonne Parish’s Schriever Water System. CDC confirmed N. fowleri in 2 treated public drinking water systems in Lousiana in September-October 2013. There are other sporadic times when it has been found in municiple water.

Mouth guards: Almost every dentist can make you a custom mouth guard. You shouldn't buy a mouth guard that is not made for you specifically or it can cause problems. Just like one size fits all shoes aren't a good idea.

Possibly: It is not a for sure thing that you would have an infection but those symptoms common for an infection that is draining such as an abcess. You may want to have a dentist take a look for you.
