Bad taste in mouth a few weeks after having a filling...

[Dickorydockwhatthe]

I was being assessed for invisalign and had to have an xray which showed up some decay on a back tooth due to a inward wisdom tooth growing against it and trapping food in between. If it weren't for the x Ray I would never have know as had no pain or sensitivity. It's the first time I've had a filling at age 40 so pretty gutted. Anyway the last week or so I've noticed that side of my mouth is smelling can't describe it but I just have a bad taste. I know the filling was quite deep and they did mention root canal which to be honest I don't see the point. But is this a sign it's infected?? I've literally had no problems until going for this assessment and having the X Ray. It doesn't feel painful or anything. I've been garlkjbg and flossing more too due to paranoia 😩

If you can then go back to your dentist for a deep clean. The bad taste you are getting is from gum inflammation/ gingivitis. It is nothing big if you do not have any pain but does require cleaning. If you want to try something on your own first then you need tepe interdental brushes. Buy a multi size pack and clean between all your teeth specially the ones at the back. Do it once daily for 3-4 days and most of your problem will be sorted. Your gums will bleed initially but once the bleeding is gone then your problem will be gone too.

OK thank you I was just worried in case it my the filling. I'm always dubious with dentists after a bad experience

This is most likely due to the solvents and low molecular weight monomers present in most resin-based dental materials. The bad taste should resolve with a couple of rinses of water or within the hour.
