Oral Complications of Chemotherapy and Head/Neck Radiation (PDQ®): Supportive care - Health Professional Information [NCI] - Oral and Dental Management After Cancer Therapy

continued...

Patients skilled at flossing without traumatizing gingival tissues may continue flossing throughout chemotherapy administration. Flossing allows for interproximal removal of dental bacterial plaque and thus promotes gingival health. As with dental brushing, this intervention should be performed under the supervision of professional staff to ensure its safe administration.

The oral cavity should be cleaned after meals:

  • If xerostomia is present, plaque and food debris may accumulate secondary to reduced salivary function, and more frequent hygiene may be necessary.
  • Dentures need to be cleaned with denture cleanser every day and should be brushed and rinsed after meals.
  • Rinsing the oral cavity may not be sufficient for thorough cleansing of the oral tissues; mechanical plaque removal is often necessary.
  • Care must be exerted in the use of the varied mechanical hygiene aids that are available; dental floss, interproximal brushes, and wooden wedges can injure oral tissues rendered fragile by chemotherapy.
  • Toothettes have limited ability to cleanse the dentition; however, they may be useful for cleaning maxillary/mandibular alveolar ridges of edentulous areas, palate, and tongue.

Preventing dryness of the lips to reduce risk for tissue injury is important. Mouth breathing and/or xerostomia secondary to anticholinergic medications used for nausea management can induce the condition. GVHD of the lips can also contribute to dry lips in allogeneic transplant patients. Lip care products containing petroleum-based oils and waxes can be useful. Lanolin-based creams and ointments may be more effective in moisturizing/lubricating the lips and thus protecting against trauma.
