Cement sepsis is an infection and inflammation resulting from dental cement being around the crown abutment margin. The body doesn't like the rough surface as it harbors bacteria. Since the body can not expel it, bone resorbs as an attempt to get away.
Before reattaching it, first lightly clean the crown inside and out with a gentle toothpaste and brush to remove any debris or old cement. Next, place a small dab of toothpaste or temporary tooth cement on the crown where it will be reattached and reattach it.
Temporary crown removal is straightforward. The dentist near you will use a soft adhesive to make it easy to remove the crowns. Permanently crowns are, however, challenging to remove. The process may be more complicated than the first procedure.

Bacteria go after what's left of a tooth by converting sugars into acid, which eats through the enamel and results in rot and a cavity or infection underneath the crown.
In some cases, the restorative material may need to be completely cut through with high-speed rotary instrument and then pried off with a narrow-ended tool. If the crown is made out of gold or metal, then removal becomes even more difficult because the material is harder to penetrate.

Dental Crown Tooth Pain
Even after a dental crown is placed on your tooth, the area underneath can still lead to pain. This occurs because there's live tissue underneath.
Infection can set in when bacteria is present during oral surgery or any time post-surgery without proper oral hygiene. It can also be caused when dental cement escapes from under the crown during cementation and gets caught in the gums.
Some patients experience pain after cementation of a cast restoration on a vital tooth. Limited data are available on the prevalence of this pain. In many cases the pain disappears within two weeks. The major cause of the pain might be attributed to more permeability of the dentine after preparation.
