Dear Sir/Madam,
I have a bridge in the lower right that fills the gap left by missing teeth 6 and 7; the bridge is attached to teeth 5 and 8. The wisdom tooth supporting the bridge has become sensitive to thermal stimuli, both cold and hot. Does this already mean that the supporting wisdom tooth requires treatment, and is such treatment even possible?
Thank you for your answer

Dear Sir/Madam!

The causes of hypersensitivity to thermal stimuli and changes in osmotic pressure can be different. Gum recession allows thermal and other stimuli to act directly on cervical and root dentine, which is not protected by enamel or an artificial crown, thus causing unpleasant sensations (sensitivity, pain). If these sensations disappear within a few seconds after the stimulus stops, we assume a minor, reversible injury to the dental pulp (the condition will improve on its own or the cervical dentine may need to be protected with a special resin). Radical procedures are not necessary in this case.
The cause may also be secondary caries beneath the crown. The caries must certainly be removed, which requires removal of the bridge. If the painful sensations do not disappear within a few seconds after the stimulus stops, root canal treatment is also necessary, because the symptoms indicate irreversible damage to the dental pulp, which must be removed.

Have a nice day!
