<s>[INST] i have not been to a dentist for three years after a bad treatment when he hit my nerve drilling and now i have  a broken widsom tooth which is in half and a hole in another tooth,my teeth are yellow even tho i brush and my gums are sore and some times bleed and i suffer from tooth pain and i am scared of eating incase i get ooth pain please help me i want my teeth to look nice and pain free [/INST] hellooo...read thru ur query...first of all i must say that dont be tensed...nxt thing i can say is that dont be scared of dentist...bcoz of one bad experience...it might have happened by chance that resulted in pain for u.(which im also sad to hear)...that doesnt mean everytime he causes pain...(so cheerup)...regarding yellowing u dont have to be sad its natural that many people have yellow teeth (including mine).yellowing doesnt mean that u have bad oral hygiene or u dont brush..its due to excessive deposition of dentin beneath the enamel...and regarding hole in the tooth u have to go to a dentist get it filled(if deep rootcanal treatment mayne required which can be confirmed by xray)...and if u still want to whiten ur teeth there are procedures like bleaching or veneering which will be done by dentist...to prevent further caries to ur teeth brush twice daily use chlorhexidine mouthwash and do flossing...these all can reduce the bleeding from gums(gingivitis)..so be cool meet a dentist get it done...hope ur benefitted something from this reply..have a healthy day!!! </s>
