A diet largely consisting of squid doesn't do much for the state of your digestive system or your breath, you really don't want to be breathed on by an elephant seal. Most of the time pods are quite fairly restful places in a constant snoring and guttural grumbling sort of way, but every now and then one of the inner most seals decides it wants to go to sea.
I have never had the severe symptoms you describe after a cleaning, that's quite a reaction, but have felt very tired. I chalked it up to emotional exhaustion as I hate having my teeth cleaned. I agree with Wayne Mikie, it feels good to see your name. Hope you are feeling better.
Full Answer. A bad tooth usually begins as a cavity. Bacteria in the cavity can lead to infections. Some symptoms of a tooth infection can be pain, face or mouth inflammation and pus formation at the tooth site. It also can cause nausea, fevers, vomiting and chills due to high fevers.
