Hello there,
It is common for a calcified tooth to get infected.
calcified tooth can produce severe pain, swelling, and infection. Often, the outer appearance of a calcified tooth changes, causing it to appear and look darker yellow in colour.
It brings severe pain in its wake. The pain intensifies when you bite down or place pressure on the affected tooth. Additionally, you may experience tooth sensitivity when you eat hot or cold food and drinks. The pain can also originate from inflammation of the gums.
No,calcified tooth does not cause halitosis but
calcium deposits, also known as tartar or calculus, arise when plaque on the teeth hardens and thickens. In addition to causing visible yellow, brown, or black deposits, they can cause halitosis.
