I noticed a small red spot  on my upper gum directly above the gum line of my tooth. I noticed it about a week ago while flossing . There is no sign of infection,bleeding or any discomfort etc. What might cause this and should I have my dentist check it out ?
Thanks for your query, I have gone through your query. The small red spot on the upper gum can be because of the trauma secondary ti the use of floss or any tooth brush injury, or it can be because of gum infection. Consult an oral physician and get it evaluated. If it is gum infection get your teeth cleaned. If it is secondary to trauma, then you can apply chlorhexidine gel over the red area. If you have pain, then you can use topical anesthetic like lidocaine gel 2%. I hope my answer will help you, take care.
