What does “Periodontal pocket” mean?
A periodontal pocket is a pathologically deepened space between a tooth and the gum. Gum inflammation and damage to periodontal attachment and bone are assessed together to determine the cause and treatment extent.
How is depth measured?
At the dental clinic, a thin periodontal probe is inserted at several points around each tooth to measure pocket depth and record bleeding. The distribution of findings across the teeth and previous records matter alongside individual measurements.
Does a deep pocket always mean bone damage?
A deep measurement caused by swollen gums must be distinguished from loss of periodontal supporting tissue. The gumline, attachment level, and bone on radiographs are assessed together.
What is checked after treatment?
After plaque and tartar removal and oral hygiene care, changes in bleeding and pocket depth are checked. If deep lesions remain, additional treatment and maintenance are planned.
Frequently Asked Questions
Can I measure the depth at home?
Do not measure or poke with sharp objects. This can injure tissue and does not allow reliable assessment; a dental examination is needed.
Is all treatment finished once the depth decreases?
Bleeding, hygiene, remaining support, and risk factors also need assessment. Maintenance may be needed even with a good treatment response.
