Had a large tooth filling and now you have earache and a sore head?

Experiencing earache and a sore head after a large tooth filling could indicate several issues, including referred pain from the dental procedure, an infection, or inflammation in the surrounding tissues. It's important to monitor the symptoms and consult your dentist or healthcare professional if they persist or worsen. They can assess for any complications, such as a possible dental abscess or issues with the filling itself. Taking over-the-counter pain relief may help in the meantime.
