My puppys molar is sideways and bleeding?

6
month old boxer, right side back tooth looks like tooth was taken out and put
back in on the outside of his gum. Was teething, whole face swollen. Eating and
playing normal. never seen this before, taking to vet in the am. Happened today.
Due to his tooth sideways which is not loose he has rubbed his inside of mouth
raw, causing the swelling.
The rubbing caused a tear that inturn in becoming inflammed. There is really
nothing to do but have the tooth pulled..The vet will knock him out to do this
don't worry he won't feel any pain. Puppies are like kids. They usually aren't
aware of pain unless attention is called to it. So long as he does seem
lathargic or hurting he'll be fine. However, if he starts to appear sick,
lathargic, or abnormal take him to the vet it is a sign of infection and may
lead to sepsis*usually you can find an animal ER they are VERY expensive!*
aww poor thing :[
