Everyone does not need periodontal maintenance. Those who are suffering from advanced gum diseases need to undergo this procedure. Regular dental cleanings and good oral hygiene routines can only do so much to remove bacteria from the gums. If you have deep gum pockets, you need periodontal maintenance to eliminate your gum diseases. Furthermore, anyone who experiences periodontal disease signs, including bleeding, inflamed, discolored, or receding gums, should get scaling and root planning at the dentist.
