Why is it I have had no cavities for years, but I have periodontal disease? Aren’t they caused by the same thing?
I congratulate you for not having cavities for a long time. I know it can be confusing when you have one condition, but not the other. This can happen because they have different causes.
Periodontal disease, a condition of bone and gum loss, is caused by bacterial and mechanical factors. There are several bacteria associated, including P. gingivalis and A. actinomycetemcomitans. Stress on the bone from grinding and clenching can also induce the disease. You may have a higher incidence of either of these factors.
Dental cavities are caused by the bacteria streptococcus mutans. The carbohydrates we eat are food for the bacteria, which then produce acids that destroy the protective enamel of our teeth. This, combined with dry mouth, systemic diseases and/or acidic drinks allows the cavities to grow exponentially. You may have a lower incidence of these factors.
You can prevent both conditions by brushing regularly — two times a day at a minimum — and flossing and/or using a Waterpik at least once a day. You can also prevent periodontal disease by using a night guard retainer. The more regular you are with your dental check-ups, the earlier either condition can be diagnosed, making it less painful and less expensive to treat.
