Poorly controlled diabetics, are at greater risk of oral complications. These include dry mouth, poor healing and decreased flow of saliva. Infections in the mouth are also more likely, such as gum disease (also known as periodontal disease) which can lead ultimately to the loss of teeth, thrush (a fungal infection), and lichen planus ( a disorder of the skin and oral soft tissues).
These problems can be prevented or at least minimised with professional help. Although there is no cure for lichen planus, a dentist may treat it with topical anesthetics or prescription medications.
