Cancer scare.

So i had a dental check up Monday and my dentist was worried because I am getting these small white bumps on the lining on my gums. The small white bump has been there since January and won't go away. I dont know which Doctor to see my primary or what? But my gums went from being perfect to hideous in just a couple months. Also my periods are all over too. Everytime I make an appointment to see my primary doctor there's always an excuse and can't be seen till December. Mind you i do not drink or smoke because of my asthma. I do live in Arizona so I am in the sun alot. Does anyone have these spots i am really worried about my health and no doctor can give me the right answers one doctor will say I have a thyroid disease the next will say I dont and that I have a herpes disease like that the hell? I hate the doctors in my town.
