Brittle teeth are dangerous because they can break off or fall out. Your diet, genetics, bone development and habits all affect the condition of your teeth. Yet, some people's brittle teeth are due in part to specific medical conditions. Those with brittle teeth must avoid eating and drinking certain things. Iced tea is a big no-no for those with them. Good oral health and habits will decrease your chances of brittle teeth even when medical conditions are involved.
Periodontal disease is one of the gums, teeth and jaw bones. It begins with gingivitis and may have symptoms of red and swollen gums. Eventually if not treated, it progresses to periodontal disease in which the structure of your teeth is compromised. Brittle teeth would occur in more advanced stages of the disease.
Osteoporosis is a disease that causes brittle bones in general. The teeth can be affected especially as those with the disease age. Those with low jaw bone density are most at risk to lose teeth. See your dentist for a thorough oral exam if you have been diagnosed with osteoporosis.
Kidney disease not only can cause bad breath and taste in your mouth, but it leads to bone loss. If the bone in the jaw is affected, brittle and loose teeth could be the result. When the kidneys do not function properly, they do not effectively process calcium which is important for strong teeth.
Reduced nerve tissue means less nerve tissue is stimulated. This happens as you age. So when you eat, drink or even fracture your teeth, the teeth are less aware of what is happening. The reduction in nerve activity certainly can lead to brittle teeth according to the University of Missouri Extension website.
