It is essential to care for your teeth following a professional cleaning, and understanding when to eat after your appointment can make all the difference. If you received a fluoride treatment or air polishing during your visit, you should wait 30 minutes before having any food or drinks. However, if neither of those treatments was done, no waiting time is necessary. To protect the shining results of your cleaning, we advise not eating anything that could potentially stain or discolour your teeth for at least 6 hours afterwards.
