## Your Oral Health Journey
 Comprehensive patient guide to gum health, tooth decay, and maintaining oral hygiene. 

## The Periodontium
 Details the support system for teeth: gingiva, periodontal ligament, alveolar bone, and cementum.

## Gingivitis & Periodontitis
* **Gingivitis**: 100% reversible early gum disease characterized by red, swollen gums.
* **Periodontitis**: Advanced disease involving irreversible bone loss. Covers Stage I (Initial) to Stage IV (Advanced) and Grades A to C based on progression speed.

## Diagnosing and Treating Gum Disease
* **Diagnosis**: Uses pocket probing (1-3mm is healthy, 4mm+ is concern), visual exams, and X-rays.
* **Treatments**: 
  * D1110: Regular Cleaning
  * D4346: Periodontal Scaling
  * D4341: Scaling & Root Planing (Deep Clean)
  * D4910: Periodontal Maintenance (every 3–4 months)

## Tooth Decay Process
Stages from white spots (reversible) to enamel/dentin decay, pulp damage, and abscess. Includes details on Root Caries and Dentin Hypersensitivity.

## Xerostomia (Dry Mouth)
Causes including medications (400+ types), diabetes, and aging. Saliva is critical as it neutralizes acid and washes away bacteria.

## Dental Radiographs (X-Rays)
* Bitewings: Find cavities between teeth.
* Periapical: Shows whole tooth from crown to root.
* Modern digital X-rays use up to 80% less radiation than traditional film.

## Oral Home Care
* **Brushing**: Recommends the Modified Bass Technique; 2 minutes, twice daily. Electric brushes can remove 21% more plaque.
* **Interdental**: Brushing only cleans 60% of surfaces. Options include traditional floss, interdental brushes, and water flossers.
* **Preventive Agents**: Use of Fluoride, Nano-Hydroxyapatite, Xylitol, and Dental Sealants.
