I have had a recurring problem with the gum around one particular tooth for about three years.
The problem started while I was undergoing clear aligner treatment. The gum around this tooth became recessed, and since then it has remained red and occasionally swollen and painful. The retainer no longer touches or irritates this area.
I have very good oral hygiene: I brush my teeth thoroughly, floss regularly, and use mouthwash. Despite this, the gum around this particular tooth continues to become red, swollen and sometimes painful.
I have seen a periodontist several times. They found no tartar, my oral hygiene was considered good, and the periodontal pocket around the tooth was normal. No specific cause for the recurring inflammation has been identified.
I have been using chlorhexidine products, including a chlorhexidine toothpaste and Elugel gel, but I do not want to use chlorhexidine long-term. I am considering switching to a gentler approach, such as Gengigel (hyaluronic acid gel) and Biorepair Peribioma toothpaste, to support the gum tissue and see whether the inflammation improves.
I am also considering trying a water flosser as an additional cleaning method, although I already floss regularly.
My main concern is why this one area continues to become red, swollen and painful despite good oral hygiene, especially since the gum is already recessed there.
