Dental Hygiene is an extremely underrated prep
I find the prepper community does not talk about this much, but dental hygiene is an extremely important prep. I am not even talking about toothbrushes and toothpaste in your bug out bag. I am talking about going to the dentist and getting a checkup every 6 months to a year.
The reason being is an a time of emergency, a cavity can be extremely painful or deadly depending on the level of shtf. If its a financial emergency a cavity or the potential infection that results can be extremely expensive to get fixed if you don't have insurance.
In a full out shtf situation, a cavity can result in an infection that can spread to your bone and cause sepsis.
TLDR: Its important to have your dental hygiene and health squared away before an shtf situation in the form of check ups.
