What Causes Tiny Bumps On The Jaw?

Hi, I believe i m being a bit paranoid lately, My first child was recently born and i ve suffering anxiety over my issue. My wife tells me it s nothing but over my right side top teeth located on my gums, i noticed a small raised bump painless and to the right looks like a small painless flesh colored raise of tiny bumps on the light. I really had to focus on it to see it in the mirror. I occasionally smoke, and not really an alcohol drinke, and recently ate spicy foods. I also noticed the same tiny cluster on the corners of my mouth not really visible to the eye until i use my tongue to raise my lower lip to see it in the light. Please regard my question it been driving me nuts. !!!
