Tooth with filling hurts years later
The dentist checks the filling margins, contact, bite and cracks, tests the pulp and supporting tissues, and takes an X-ray when indicated.
The short answer
A filled tooth that becomes painful later needs a fresh assessment because the original restoration does not rule out new decay, fracture or pulp inflammation.. Avoid chewing hard foods on that side, keep the area clean, and use labelled pain relief only if suitable for you.
How can you protect and clean a painful filled tooth?
Avoid chewing hard foods on that side, keep the area clean, and use labelled pain relief only if suitable for you.
When should a painful filled tooth receive prompt care?
Seek prompt care for spontaneous pain, lingering hot or cold pain, swelling, pain on biting, a broken filling or fever.
What should you ask about treatment for the filled tooth?
Ask whether the filling is leaking or high, whether the pulp is recoverable, and whether repair, replacement, root canal treatment or removal is needed.
Frequently asked questions
What is the most useful first step?

Can home care replace an examination?
