[|Human|] just recently maybe a few days ago I noticed a dark red line at the bottom of two of my back teeth.  one of the teeth I had a root canal done several years ago.  I never noticed it until it became sore a few days ago.  the soreness didnt occur until after I found out I was pregnant.  I have a dentist appt. coming up but I would like to know now what it could possibly be.
[|AI|]  Hello, Thanks for consulting Chat Doctor, Read your query, as you have redness in root canal treated tooth after several years back this can be due to inflammation of gingival or periodontal ligament, may be due to pocket formation in tooth, or due to pregnancy induced. For this you should consult dentist and go for examination, investigation IOWA X-ray of tooth and its treatment Oral prophylaxis, in meantime you can do warm saline rinses. Hope it will help you.  Wishing you good health. Regards,
