Thin gums and visible tooth roots: what do measurements tell you?
The measurements describe four things: how far the gum edge has moved from where enamel ends (recession depth), how much firm, keratinized gum remains below it, how thick that gum is (thin or thick phenotype), and whether the bone and tissue between the teeth are intact (recession type 1, 2 or 3). Together they indicate how stable the area is likely to be and how much root could reasonably be covered.
They do not by themselves decide treatment.
Measurement table
| What is measured | How | A higher or lower value usually suggests | My number |
|---|---|---|---|
| Recession depth (mm) | Probe from enamel edge to gum edge | Deeper is more exposed root | |
| Keratinized gum width (mm) | Visual and probe, from gum edge to where loose lining begins | Narrower bands are less stable | |
| Gum thickness | Whether a probe shows through the gum | Thin phenotype is monitored more closely | |
| Tissue between teeth | Visual, probe, x-ray | Intact tissue allows more coverage | |
| Pocket depth | Probe | Deeper pockets point to gum disease | |
| Bleeding | Probe | Bleeding means inflammation to control first |
Recession types in plain language
Type 1: the tissue between the teeth is intact; full coverage is often achievable. Type 2: some loss between the teeth, but not beyond the front surface; partial coverage is more typical. Type 3: loss beyond the front surface; coverage is limited. These are expectations, not promises.
Thin versus thick phenotype
Thin gum shows the probe through it and has less reserve against brushing, inflammation or tooth movement, so it may be watched more closely or thickened before orthodontics. It is a description of anatomy, not a disease.
What the numbers do not say
Whether you need surgery. A deep, stable, comfortable recession may be monitored; a shallow but progressing one with sensitivity may be treated. The American Academy of Periodontology frames grafting around protecting roots and reducing sensitivity (AAP); the American Dental Association notes that receding gums expose roots to decay and sensitivity (ADA).
Questions to ask about your numbers
Which teeth, and what are the measurements? Is this stable compared with last time? What type is the recession? Is my gum thin or thick? What would you do if we only monitored?
The studio lists gum grafting with a consultation first (studio).
Next step: Request a consultation or call (805) 565-5111. A request is not a confirmed appointment; the office confirms times during its listed hours (Monday to Thursday, 8 am to 5 pm, plus select Fridays).
Thickness and recession measurement sheet
In words: measure down from where enamel ends to the gum edge (recession depth); measure the band of firm pink gum below that (keratinized width); see whether a probe shows through the gum (thickness); check whether the triangles between teeth are full (type).
| Tooth | Recession depth | Keratinized width | Thin or thick | Type (1/2/3) | Stable since last visit? |
|---|---|---|---|---|---|
