[|Human|] Hi there,I am an 18 years old female and I just woke up and noticed I have a small red spot directly above my lateral incisor on the left side. It doesnt hurt to touch and isnt bleeding...its smooth and doesnt stick out from the rest of my gums. I am worried though, because it is directly above a tooth that I had injured 4 years ago along with my left central incisor. Both of these teeth were shoved back to the roof of my mouth after accidentally running into someones skull while playing capture the flag. The teeth stayed in tact and my dentist simply numbed my mouth and put the teeth back in place by using his two fingers and blotting it...after they were set in place, he placed an invisalign across my top 4 front teeth for about 2 months. I can still feel hot and cold with those two teeth, its a little dull but I can still feel it. So all in all...red spot on gum right above the left lateral tooth, no pain or bleeding, just noticed it this morning, have had an injury on this tooth in the past but havent had any problems with it in the past 4 years. I am incredibly nervous...
[|AI|]  Dear friend. Thanks for sharing your concern. Also thanks for giving complete history. I would like to explain to you that according to the history given, it appears as though your lateral incisor is non-vital and has developed periapical abscess. But since you have mentioned in your history that there is no associated pain or swelling, and also you can feel the sensation there, then definitely it could be a lesion due gum infection also. There is only two possibility here.  Either it is a gum infection causing redness there due to pocket or the second and most likely reason being the tooth has turned non-vital upon receiving the blow directly or indirectly. Therefore, please make a visit to your dentist and a simple clinical evaluation along with an x-ray will confirm the diagnosis. Meanwhile you can do warm saline rinses. Hope it helps. Thanks. Take care.
