Pulpitis is sensitive to both cold and heat, and this sensitivity is a symptom of the condition. The dental pulp is protected by enamel and dentin, and generally does not exhibit sensitivity. However, if there are deep cavities, split wedge-shaped defects, severe wear, or fractures that compromise the outer protection, it can lead to inflammation of the dental nerve and sensitivity to temperature changes. In such cases, nerve removal treatment, also known as root canal treatment, is required. Root canal treatment involves the removal of the pulp and necrotic material from the root canal, disinfecting it, and tightly filling the root canal to eliminate any infection that could adversely affect the surrounding periapical tissue and prevent re-infection. Root canal treatment requires three to four follow-up visits and can be costly. Therefore, it is important to detect and treat cavities early.
