Teeth are considered part of the skeleton system even though they are not bone. Teeth are the strongest substance in your body being made up of enamel and dentin.

There are typically around 270 bones in human infants, which fuse to become 206 to 213 bones in the human adult. The reason for the variability in the number of bones is because some humans may have a varying number of ribs, vertebrae, and digits.

A baby’s body has about 300 bones at birth. These eventually fuse (grow together) to form the 206 bones that adults have. Some of a baby’s bones are made entirely of a special material called cartilage (say: KAR-tel-ij).

Periodontitis (per-e-o-don-TIE-tis), also called gum disease, is a serious gum infection that damages the soft tissue and, without treatment, can destroy the bone that supports your teeth. Periodontitis can cause teeth to loosen or lead to tooth loss. Periodontitis is common but largely preventable.

Existing bone loss does not make Invisalign treatment impossible. Invisalign treatment actually can help to stimulate bone growth in areas damaged by periodontal disease.

On its own, bone loss cannot be reversed. Left untreated, the bone in your jaw and around your teeth will continue to resorb, leading to more tooth loss, disease, and pain. There is good news! In most cases, dental bone loss can be stopped.

Bone loss can be prevented by giving the jawbone a replacement tooth with a root that can exert the same or similar pressure as natural teeth. This is done immediately after extraction by replacing single teeth with dental implants, or by using a fixed implant-supported bridge or denture.

Gum disease may increase your risk of getting respiratory infections, such as chronic obstructive pulmonary disease (COPD) and pneumonia, according to the Journal of Periodontology. The infections might be caused when bacteria from the mouth are inhaled into your lungs, possibly causing your airways to become inflamed.
