For our patients who are unable to tolerate traditional restorative treatment, this is an excellent deferment option. The use of SDF in dentistry has been well documented for its safe and successful ability to stop tooth decay. Its application is a conservative approach, and typically does not require sleepy juice (numbing), or removal of tooth structure. Treatment with SDF does not usually prevent the need for a regular filling in the future. Eventually, the dentist will place a permanent filling on the tooth when the child is more mature and able to cooperate for dental treatment.
