Sudden sharp pain in teeth sometimes.

Hi Doctor, From the last few months I am having sudden sharp pain at two to three specific points, in my upper and lower, premolars and molars, overall in the right side of my mouth, while chewing solid hard foods. It is very difficult to detect which exactly is the point where it is hurting. But I have noticed it increases after I eat sweet foods and leave my mouth unbrushed. This pain comes and goes, for example it might hurt sometimes while eating something hard or might not hurt. This has reduced over time and I have seen that rinsing my mouth after eating something sweet or drinking milk has helped the pain to reduce it's frequency to a large extent but it is not completely going away. Also I am not seeing any cavity on my tooth and my tooth is completely white.
