Hi: No, individual 'bad' teeth will not cause an abscess in an area away from the tooth or its surrounding tissues except in the case of a serious infection that is spreading to the tissues around that particular tooth.
So for a lower right 'bad' tooth to infect the palate, nope.
My bigger concern would be the red spot on your palate. How long has is been there? Have you noticed any change in size, color or texture? Is it better, or less in size than it was two days ago? Did you notice any tissue sloughing or peeling from the surface of the lesion recently?
Most likely, it's a burn, the most common cause is hot cheese that sticks, such as when you take a bite of hot pizza, or soup that's just too hot. Or, you may have abraded it from a habit, such as holding a pencil in your mouth. These usually heal within a week.
However, if it persists for more than a week or it's getting worse with time, you should absolutely have your dentist evaluate it.
