Understanding the Link Between Dentures and Bone Loss

Introduction

Dental health is crucial to overall well-being, and dentures play a significant role in this. However, a common concern surrounding dentures is whether they can cause bone loss. This article delves into the relationship between dentures and bone loss, addressing prevalent misconceptions and offering insights based on current dental knowledge.

Dentures and Bone Loss: Fact vs. Fiction

Myth: Dentures Cause Bone Loss

One pervasive belief is that dentures themselves are the primary cause of bone loss. This is a misconception. The truth is that the absence of natural teeth, rather than the presence of dentures, is the key factor in bone resorption.

The Science Behind Bone Resorption:

The alveolar bone, which surrounds and supports teeth, is continuously reshaped by the forces applied during chewing and tooth use. When teeth are absent, these forces disappear, leading to bone resorption.

Dental implants, on the other hand, provide a similar loading force to the bone, preventing bone loss in areas where implants are placed. Therefore, dentures, which distribute biting forces across the jaw, can actually help preserve bone density.

How Dentures Can Contribute to Bone Loss

While dentures do not directly cause bone loss, their improper fit can indirectly contribute to this issue:

Inaccurate Fit: If a denture does not fit properly, wearing it can cause continuous irritation and pressure on the gums, leading to sores and discomfort. This can contribute to bone resorption over time.

Back Teeth Alignment: Proper denture design is crucial. Back teeth should be aligned at a 0-degree angle to ensure that the denture remains stable and does not cause side-to-side movement, which can lead to bone trauma.

Protection for Bone Health

To protect bone health, denture wearers are advised to:

Custom Fitting: A properly fitted denture that suits the shape and contour of the jaw can minimize the risk of bone loss.

Daily Handling: Removing dentures at night allows the jaw to rest and reduces the risk of minor trauma to the bone.

Regular Dental Check-ups: Regular visits to the dentist ensure that the dentures are still fitting well and that no new issues are developing.

Conclusion

Understanding the relationship between dentures and bone loss is crucial for maintaining dental health. While dentures do not inherently cause bone loss, improper fitting and lack of proper care can contribute to this issue. By addressing these factors, individuals can preserve bone density and maintain oral health effectively.
