What is a common cause of dental pulp inflammation?

• A. Overheating during a procedure
• B. Untreated tooth decay
• C. Frequent brushing
• D. Excessive fluoride use

Answer: (B)

Dental pulp inflammation, also known as pulpitis, is often caused by untreated tooth decay. When tooth decay progresses beyond the enamel and dentin, it can reach the pulp, which contains nerves and blood vessels. This exposure leads to inflammation as the body responds to the bacterial infection within the pulp. The trapped bacteria release toxins that irritate the pulp tissue, resulting in pain and swelling.

Other factors contributing to pulp inflammation, though not as common as untreated decay, include overheating during dental procedures or trauma to the tooth, but these are less frequent than the effects of decay. Frequent brushing and proper dental hygiene typically help prevent tooth decay and are not associated with causing pulp inflammation. Excessive fluoride can lead to dental fluorosis but is not a direct cause of inflammation in the pulp.
