Why would a two year old crown suddenly start hurting when you touch it or bite down.?

Potential Causes of Sudden Pain

When a two year old crown suddenly starts hurting when touched or bitten down, there are various potential causes. Here are a few common reasons:

1. Food Impaction: Food particles, such as small seeds or pieces of meat, can get stuck under the crown's margin. This impaction can cause pain when biting down or even touching the area.

2. Recurrent Caries (Tooth Decay): Despite the presence of a crown, tooth decay can still occur around the margins of the crown where there is a gap between the crown and the tooth. If decay has formed, it can irritate the tooth's nerve, leading to sensitivity and pain.

3. Pulpitis (Inflammation of the Dental Pulp): If bacteria have reached the pulp (nerve) of the tooth, it can become inflamed. This inflammation can cause significant pain when biting or touching the affected tooth, including a crowned tooth.

4. Crown Dislodgement: In some cases, the crown itself may become loose or slightly dislodged. This lack of proper fit can cause discomfort and pain when chewing or putting pressure on the crowned tooth.

5. Heightened Dental Sensitivity: As a child's mouth develops, their teeth and surrounding structures can become more sensitive. This increased sensitivity can make previously asymptomatic issues, such as minor crown-related problems, more noticeable and painful.

6. Allergic Reaction: Rarely, a two year old's sudden crown pain may be a sign of an allergic reaction to the crown's material, such as metal alloys or resin-based cements.

Immediate Action

If a two year old experiences sudden pain with a crowned tooth, it's essential to schedule a prompt visit to a dentist. The dentist can accurately assess the cause of the pain, perform any necessary treatments, and ensure the child's dental health.

Remember that this information is general and a dental professional's assessment and guidance are crucial in addressing any child's dental concerns.
