Thanks for writing to us.
Headache,ear as well as jaw pain can be due to inflammation of flap overlying impacted wisdom tooth
Taste of blood in mouth usually occurs due to bleeding gums
as a result of gingivitis
I would advice you to get a thorough scaling done.Impacted tooth
has to be extracted or retained depending on position of tooth underlying.
Include fruits as well as fluids into your diet.
Vitamin c supplements has to be administered.
Hope this helps.
