Thanks for your query, I have gone through your query.
Basically you have two problems,
One is pain in the ear and the mis aligned jaw, difficulty in mouth opening can be because of the disc displacement in the temporomandibular joint secondary to excessive opening of the jaw during yawning. Nothing to be panic, Consult a oral physician and get it diagnosed. You can stop using the splints for few days. You can take anti inflammatory drugs like piroxicam 20mg twice daily on first day and twice daily on next 6 days. You can also take muscle relaxants like chlorzoxazone. You can give hot fomentation over the joints. Do not eat hard things, do not open your mouth too wide. take soft diet.
The second problem is, you have infection of the gums surrounding the wisdom tooth resulting in space infection. Consult a oral physician and get a radiograph done to rule the amount of space present for the tooth to erupt if space is there for the tooth to erupt then the gum covering over the wisdom tooth can be removed.
If the space is not available then you have to get the wisdom tooth removed.
Mean while you can take a course of antibiotics like amoxicillin 500mg and metronidazole 400mg tid for 5 days (if you are not allergic).

I hope my answer will help you, take care.
