Radiotherapy-induced hyposalivation further complicates the situation and decreases the quality of life. Consequently, dental caries, mucosal diseases such as candidosis and sialadenitis become problematic to treat. Hence every effort should be focused on prevention. In caries prevention intensified. fluoride therapy together with dietary counseling is needed. Oral cancer patients also need to be frequently referred to dental hygienists for professional cleaning.

In addition, patients with severe dry mouth cases may also benefit from the prescription of pilocarpine tablets.
