Unless you are allergic to peanuts it is a pretty good assumption that you have had peanut butter. Some indications not that peanut butter has been found as far back as the Aztec and Incan empires. It is made from ground dry roasted peanuts and can contain additional ingredients to change the texture and taste and can come in two main types which include smooth and crunchy. Now you might be asking how can peanut butter be bad for your teeth and in with respect to problems with your teeth it falls into two types of problem areas the first being that it is a sticky food that likes to stick and stay attached to and between teeth which supply bacteria in the mouth with a plentiful food supply as well as the second issue with peanut butter is that it is full of sugar. These sugar especially now that they are sticking to your teeth increase the number of bacteria in your mouth and increase the breakdown of your teeth. So while it is a good source of protein and a staple too many families its ability to stick to your teeth and aid in the growing of bacteria that attach the teeth makes peanut butter a product that is secretly bad for your teeth. Meaning if you can make sure to brush it out after eating or some dentists recommend you try to use almond butter in peanut butters place because it has less sugar.
