Does deep cleaning hurt?
Tell the team if your gums are sensitive. Your dentist explains how the treatment is made comfortable before starting.
How many visits are needed?
It depends on how many areas need cleaning. Localized cases may need fewer visits than full-mouth periodontal cleaning.
What happens after deep cleaning?
You receive home-care guidance, and follow-up visits check gum health and whether regular maintenance is needed.
