Hi I had two dental implants placed in my front jaw to hold a bridge of four front teeth. Unfortunately the implants for various reasons failed. I therefore had a bridge fitted to my canine teeth. I had the bridge remade and refitted around 6/7 years ago. The new fit wasn't great. For a while now I've had a bit of bulging on the gum line but it seems to be getting worse and the gum where the implant is is red. Do I need to see a dentist? What could it be?
