Hi, I had them cleaned a few months ago. But this inflammation happened after I spent a week away staying at a hostel with limited access to my usual care equipment. I usually use a hydropulser to clean between my teeth because they are close together making flossing tricky, and I have two implants on the lower jaw as not all my adult teeth came through. Tbere I only had a regular toothbrush and very early flight. I might have nlt brushed that morning. Maybe that is how this happened. Seems like a good idea to get a second opinion. I don't want to do any expensive surgery which may be useless. Although the tooth no longer hurts as much it is sensitive when I bite on it and it does feel a little bruised above the teeth, I guess where the sinus is. It hurts to touch here or if I strain cheek muscles like in a big smile. I don't have any other symptoms so maybe just inflammation that irritated this area too? I'm going to see if it stays relatively pain free this eve then see if I can book in to get a second opinion..
