Tooth pain in the cold and hot, may be the emergence of reproducible pulpitis or non-reproducible pulpitis, may also be the emergence of dentin sensitivity.
1. Reproducible pulpitis: When the teeth are stimulated by cold or heat or when the caries is deep, it can cause reproducible inflammation of the pulp, which produces transient pain to external hot and cold stimuli, but when the stimulus is removed, the pain will disappear immediately.
2. Irreducible pulpitis: When teeth are exposed by hot or cold stimulation or caries for a long period of time, it can lead to irreducible pulpitis, which produces severe pain to external hot and cold stimulation, and the pain can be sustained.
3. Dentin sensitivity: when enamel defects dentin exposure, can cause dentin sensitivity, the outside world of hot and cold stimuli produce pain and discomfort, especially sensitive to mechanical stimulation.
It is recommended to go to the hospital for examination and treatment in time to avoid the aggravation of inflammation affecting work and life.
