<s>[INST] Hello doctor, I am 15 and I have been noticing that there is an orange substance building up on some of my teeth. My gums are swollen. There is a cavity in my canine tooth and I was wondering if there was any way I can fix it without going to a dentist because my family is very poor. So, would you recommend anything? [/INST] Hello. For more information consult a dentist online --> </s>
