When people lose many teeth due to various reasons, gaps begin to form in the jawbone. This creates a foundation for jawbone loss. As the jawbone deteriorates, even healthy teeth may become compromised.
So, what is jawbone loss? What are its symptoms? How is it treated? You’ll find all the answers and necessary details in this article.
What Is Jawbone Loss?
After a tooth is extracted, the surrounding jawbone naturally begins to deteriorate over time. This occurs because there is no longer pressure or stimulation in that area, and the surrounding bone tissue goes unused. Tooth loss can lead to reduced bone density and shrinkage in the jaw.
Jawbone loss can be prevented or treated using dental implants or other restorative procedures. If left untreated, it can have significant negative effects on oral health and the structure of the jaw.
What Causes Jawbone Loss?
There are many reasons for jawbone loss. The most common contributing factors include:
- Tooth Loss: Teeth stimulate the jawbone, keeping it healthy. Without this stimulation, bone density decreases, leading to bone loss.
- Neuromuscular Habits: Harmful habits such as teeth grinding or clenching caused by stress can contribute to bone deterioration.
- Aging: Bone density naturally decreases with age, and this can affect the jaw, leading to thinning and erosion over time.
- Hormonal Changes: Hormonal shifts during menopause can affect bone density in women and contribute to jawbone loss.
- Genetic Factors: Individuals with a family history of bone-related conditions may be at higher risk of jawbone loss.
- Inflammatory Diseases: Certain conditions can damage bone tissue, resulting in loss of bone in the jaw.
- Low Mineral Intake: Deficiencies in calcium, phosphorus, or other minerals can negatively affect jawbone health.
Other contributing factors include tumour or cyst formation, gum disease, and prolonged use of removable dentures.
What Are the Symptoms of Jawbone Loss?
Jawbone loss may not always show obvious symptoms early on, making it harder to detect until it progresses. However, common signs include:
- Tooth loss or teeth becoming loose
- Changes in facial shape
- Unexplained difficulties while eating
- Tooth decay despite good oral hygiene
- Dentures becoming loose
- Changes in mouth structure
- Jaw pain
- Dry mouth and gum issues
How Long Does It Take for the Jawbone to Deteriorate?
The rate of jawbone loss depends on many factors, including overall health, age, genetics, hormonal status, and whether there is tooth loss. Once a tooth is removed, the bone around the root begins to deteriorate quickly.
Jawbone loss typically peaks within the first 6–12 months following extraction, then continues at a slower rate.
Can Jawbone Loss Be Reversed?
Yes, with the right treatment, jawbone loss can be managed and even reversed. Treatment depends on the cause and severity of the condition. Early diagnosis allows for better outcomes. Regular dental checkups are essential for preserving jawbone health and preventing further loss.
How Is Jawbone Loss Treated?
Treatment plans vary depending on the patient. Once the cause is identified, the dentist selects the most suitable treatment based on factors like age, general health, and condition severity. Common treatment options include:
Bone Grafts: Used to repair significant bone loss. Bone from another source or synthetic material is grafted onto the affected area to reinforce the jawbone, creating a strong foundation for implants.
Dental Implants: In cases of missing teeth, dentures or bridges may be used. Properly designed and fitted prosthetics help maintain pressure on the jawbone to slow or prevent further loss.
Medications: Sometimes prescribed to slow the progression of bone loss.
Gum Surgery: For patients with advanced gum disease or periodontitis, surgical procedures may help repair the jawbone and surrounding tissues.
Lifestyle Changes: Adopting a healthier lifestyle and a diet rich in bone-supportive nutrients can aid treatment and prevent progression.
What Implant Techniques Are Used for Jawbone Loss?
Implants can still be used for patients with bone loss, but the approach depends on the cause and severity. Common techniques include:
-
All-on-4 Technique: Ideal for patients with jawbone loss. Fewer implants are used to support a full denture, offering fast and stable results.
-
Box Technique: Used to reconstruct lost bone tissue in three dimensions.
-
Zygomatic Implants: Applied when jawbone is insufficient. These implants are anchored to the cheekbone (zygoma) to support dental restorations.
How Long Does Treatment for Jawbone Loss Take?
The treatment duration depends on the chosen method:
- Box Technique: 6 to 12 months
- All-on-4 Implants: 3 to 6 months
- Zygomatic Implants: 3 to 6 months
How Can Jawbone Loss Be Prevented?
Here are some key methods to help prevent jawbone loss:
- Maintain proper oral hygiene
- Visit the dentist regularly
- Limit or avoid smoking and alcohol
- Follow a bone-healthy diet
- Seek timely intervention after tooth loss
- Get regular dental X-rays
What Happens If Jawbone Loss Is Not Treated?
If left untreated, jawbone loss can lead to further tooth loss and structural problems in the jaw. Teeth may loosen, and the jaw may become misshapen. Over time, the face may also lose its structure, leading to undesirable aesthetic changes. That’s why it’s important to see a qualified dentist as soon as possible for proper diagnosis and treatment.
