Periodontal disease can develop with or without the risk factors listed below. However, the more risk factors you have, the greater your likelihood of developing periodontal disease. If you have a number of risk factors, call us to schedule an appointment. We can advise you on what you can do to reduce your risk.

Lifestyle Factors

  • Smoking – Smoking greatly increases your risk of developing periodontal disease. It also greatly reduces the chance that treatments for periodontal disease will be effective.
  • Poor nutrition – An unhealthy diet (eg, one that is high in fat and low in vitamin C ) can increase your chance of periodontal disease.
  • Stress – Stress can hamper your body’s ability to fight off the infection that prompts periodontal disease.
