In Short, YES. However, placing a sealant requires conditioning a tooth with a mild acid - often called "acid etching". A tooth that has just received a Fluoride treatment may sometimes require a longer etching time in order to allow the sealant to "bond" to the tooth. Also, this tooth will need to be rinsed off prior to bonding the sealant in place.....Thereby washing away some of the fluoride that was just placed.
It is usually best to place a sealant at least 30 minutes after a fluoride treatment. In my practice, if we plan to place a sealant the same day as a cleaning and fluoride we have the hygienist clean and polish, then do any sealants needed and then fluoride. Please note that most dentists will replace a sealant that has come off for no additional charge if needed at the next checkup if within 6 months.
