#2 tooth with deep cavity - why infected after filling?

Whenever a tooth is drilled to have a new filling placed or an old filling replaced, the tooth is subjected to trauma. Because a tooth is a live structure with nerve and blood supply the trauma to a tooth can show in forms of sensitivity after a filling. When this happens, the tooth is hypersensitive and letting you know that it is inflamed and this inflammation can result in death of the nerve or the tooth just getting over the inflammation and go back to normal. Based on what you have told me, you may have had an inflammation in the tooth and it has gotten better, I would not do any further treatment with the tooth unless it hurts you further down the road. I would also have x-rays taken of the entire tooth showing the root of the tooth over time to make sure there is not infection at the end of the root. (if a tooth dies, over time, the nerve and blood supply in the tooth rots causing an infection at the end of the root) This can be seen on x-rays and also if you become symptomatic meaning having a toothache in the tooth. For now no further treatment is suggested for the tooth if you are without symptoms.
