Adherence
Combined adherence to healthy lifestyle factors (Mediterranean diet, physical activity, non-smoking, moderate alcohol, ideal weight) significantly reduces the risk of developing periodontitis and tooth loss.
Your gum health depends on more than just brushing. Combining a healthy diet (like Mediterranean), regular exercise, not smoking, and maintaining a healthy weight significantly lowers your risk of gum disease and tooth loss, even if your brushing habits are average.
ModerateSupportsMEDIUM confidence
participants engaging in a combination of four healthy lifestyle behaviors... were approximately 20% less likely to develop periodontitis and 30% less likely to lose teeth from periodontal causes... when compared to participants engaging in one or none of the listed healthy behaviors.
Why this rating
Based on longitudinal observational studies (Iwasaki et al.), which are strong but not RCTs.

- Subgingival instrumentation (periodontal therapy) significantly reduces glycated hemoglobin (HbA1c) levels in patients with type 2 diabetes, demonstrating a bidirectional benefit where treating periodontitis improves metabolic control.Good
- Obesity increases the risk and severity of periodontitis through systemic inflammation and adipokine release, creating a bidirectional relationship where higher BMI correlates with poorer periodontal outcomes.Good
