Yes. Fillings, especially gold and silver fillings, can react to hot and cold. Metal fillings may shrink and expand rapidly with the differences in temperature. Overtime, the persistent shrinking and expansion of metal fillings can lead to increased sensitivity and breakage in the tooth.
Composite resin and porcelain fillings better protect against sensitivity because they expand and contract at about the same rate as your natural teeth. You may feel sensitivity in fillings for up to four weeks after treatment. If you experience sensitivity in your fillings lasting longer than four weeks, contact us immediately.
