What does a blister on the lower gum indicate?
Patient: I have a very sore spot on my bottom lower gums in front.  Not red or bleeding. lt Started about three days ago.  I just had a cleaning about two weeks ago and bite wing xrays.  No issues at that time.  I do have receding gums but the hygienist told me that they were stable.  I have been using warm salt rinse with just a have received just a small about of help. Doctor: Hi..Thanks for the query..A sore spot in the gum can be due to injured gum in that area.It can cause inflammation and soreness of gum and at times formation of an abscess..It can occur due to tooth brush injury, any hard food, foreign body or food particle impaction in the gum etc..So for now you can apply Chlorhexidine ointment over the gum.Apply Lidocaine gel to reduce pain..Do warm saline gargles and antiseptic mouthwash gargles..In case if there is no improvement consult an Oral Physician and get evaluated..Localised cleaning and a short course of antibiotics can help in improving..Hope this helps..Regards..
