i eat super unhealthy and barely brush teeth but my only teeth problems are the ones from my birth

my diet nothing for breakfast i never eat breakfast what is breakfast if there is a cheeseburger for school lunch ill eat it, if theres fries i eat them, maybe milk? dinner will either be absolutely nothing or absolutely everything An entire size family bag of flaming hot doritos for right before bed Soda cosumption throughout day - 2~ soda cans Do i brush my teeth? Nah.

I eat more chips than actual food and that isnt a good thing
