Dry mouth and mouth ulcers
Hep C infection can cause a dry mouth. This can lead to bad breath, cracked lips, and a sore mouth and throat. It can also cause difficulty with eating and swallowing, mouth ulcers, tooth decay and tooth sensitivity.
Visit your dentist twice a year for a routine check up
Avoid hot or spicy foods, which can irritate a dry mouth. Choose soft, mashed or minced foods if eating is painful
Maintain good oral hygiene with regular brushing and flossing, particularly after meals and before bed. Consider rinsing the mouth with salty water and gargling with a mild mouthwash
Try using lip balm. Keep the mouth moist by sipping water regularly. Chewing sugar-free gum can stimulate saliva
Infant teething gels may provide some relief from ulcers
Try oral health products that are designed to ease the discomfort of dry mouth (these include mouthwash, toothpaste, moisturiser gel and chewing gum)
