I have a bridge and it feels loose up on my gums. The bridge itself is not loose but I feel the sensation that it is. I saw my dentist yesterday and he did an x-ray which confirmed it is not loose but my gums are irritated. He advised rinsing with salt and warm water and also a non-alcohol mouth wash. I have a follow up appointment in 3 weeks. I first noticed this feeling after my normal check up after the hygienist flossed my bridge. I use a waterpik flosser and thought that maybe the flossing with dental floss vs. my normal waterpik irritated my gums. Do you have any suggestions as to why I may be feeling this moving sensation in my gums?

Thank you!
