why do i always get mouth sores?

i’ve been getting mouth sores alot now, its a little white circle in my mouth that really hurts and stings and its hard for me to eat because it hurts so much. i brush my teeth every morning so i dont know why i always get it one after another… i use Orajel mouth sore, but all it does is numb it for like 5-10 mins. why do i keep getting these mouth sores again & again & again?! this is probably the 5th mouth sore in 3 months.

could be food allergy. keep track of what you eat. if not that, it’s probably a virus. eventually, your immune system will reduce the frequency. check with a doctor any case.
