How to get rid of infection under crown?

Treating an infection under a dental crown involves removing the crown to clean the underlying decay or infection, often requiring a root canal if the pulp is involved, followed by disinfecting the tooth and placing a new crown, though severe damage might necessitate extraction.

Dental crowns typically last 10 to 15 years, but can endure for 20 years or more with excellent oral hygiene, regular dental checkups, and the right material, with strong options like gold and zirconia often exceeding the average, while weaker materials like resin might need replacement sooner. Key factors affecting lifespan include the material, how well you care for them (brushing, flossing, night guards), teeth grinding, and your diet.

Why does my crown feel sore?

Crown pain, often felt as sensitivity or sharp pain when biting, usually signals issues like a high bite, nerve irritation (pulpitis), underlying decay, or gum inflammation, but can also stem from a loose or cracked crown. While minor sensitivity is normal for a few days/weeks after placement, persistent or severe pain requires a dentist visit to fix bite alignment, treat infection, or repair the crown to prevent serious complications like bone loss.
 

Will antibiotics help an infected crown?
