Diabetes can have several different effects on dental health. One of the most common is an increased risk for gum disease. This is because diabetes can cause changes in the levels of sugar in the saliva, which can lead to an increase in plaque formation. In addition, diabetes can also cause dry mouth, which can further contribute to gum disease. Another common effect of diabetes on dental health is an increased risk for cavities. This is because diabetes can cause changes in the way that teeth are formed, making them more susceptible to decay. Finally, diabetes can also make it difficult to heal from dental procedures. As a result, people with diabetes need to take special care of their teeth and gums.
