My upper left central incisor is sensitive to cold. The dentist placed some device against the tooth that gave me a slight electrical sensation; before that I had to moisten the tooth with saliva, and afterward he coated it with something. The tooth is now a little less sensitive to cold. I would like to know what he did and whether it will need to be repeated.
Kind regards,
Boštjan

Dear Sir/Madam!

The dentist performed a vitality test. If the tooth reacted to lower values of electrical impulse, this may indicate some inflammation of the dental pulp. The procedure has diagnostic value only, not therapeutic value. In your case, it is most likely simply hypersensitivity of the tooth neck, which can be reduced by coating the cervical dentin with special resins. We also recommend using toothpastes designed to reduce hypersensitivity. The dentist will decide whether the diagnostic procedure needs to be repeated.

Have a nice day!
