What is Dental Bone Loss?

Dental bone loss is the gradual shrinking of the jawbone that supports your teeth. It happens for two main reasons: chronic gum disease (periodontitis) that destroys bone around teeth, and tooth loss that removes the stimulation the jawbone needs to maintain its volume. Left untreated, bone loss causes loose teeth, changes in facial appearance, and difficulty replacing teeth with implants.

How Bone Loss Happens

Your jawbone stays healthy through mechanical stimulation from chewing. When teeth are lost, that stimulation stops in that area and the bone begins to resorb. Around 25% of bone width can be lost in the first year after a tooth is extracted, and it continues at a slower pace for years after.

Periodontitis works differently. The bacteria that cause advanced gum disease produce inflammation, and your own immune response gradually destroys the bone that anchors teeth in the socket. This is why patients with untreated gum disease eventually experience loose teeth.

Signs of Bone Loss

• Receding gums (roots begin to show)
• Loose or shifting teeth
• Changes to how your bite feels
• Gaps forming between teeth
• Sunken cheeks or lips after long-term tooth loss
• Ill-fitting dentures

Many patients have significant bone loss without obvious symptoms. It is usually detected on dental x-rays or CBCT scans during routine exams.

Stopping Bone Loss

The right treatment depends on the cause and stage:

• Active gum disease: treated with deep cleaning (scaling and root planing), laser gum treatment, or surgical intervention for advanced cases
• Missing teeth: replaced with dental implants, which restore chewing stimulation and preserve bone
• Significant bone deficit: rebuilt with a bone graft before or during implant placement

Rebuilding Lost Bone

Bone grafting is a routine procedure that adds bone volume back to the jaw. The graft material can be:

• Your own bone (autograft) from another area
• Donated processed bone (allograft) from a tissue bank
• Animal-derived bone (xenograft), typically bovine
• Synthetic bone-substitute material (alloplast)

Over 4 to 6 months, your body replaces the graft with your own bone, restoring the volume needed for implants or improving support for existing teeth.

Frequently Asked Questions

Can bone loss be reversed?

Once bone is lost, it does not regrow naturally in most cases. It can be rebuilt through bone grafting, and further loss can be prevented by treating gum disease and replacing missing teeth with implants.

How much bone loss is too much for implants?

Most cases with even significant bone loss can still receive implants with grafting or specialized techniques like zygomatic implants. A CBCT scan is the best way to know your specific situation.

Does gum disease always cause bone loss?

Gingivitis (mild gum disease) does not cause bone loss. Periodontitis (advanced gum disease) does. Catching gum disease early with regular checkups is the best prevention.
