After deep cleaning, any swelling or discomfort should subside within a couple of weeks. The time will vary from patient to patient, depending on the extent of their infection. To promote gum healing and keep your mouth free of bacteria, you’ll want to follow any instructions given to you by Dr. Spaulding and rinse your mouth with warm saltwater. We also recommend using over-the-counter pain medications to ease any discomfort or swelling you may experience after a deep cleaning.
