Dry Mouth and Hyperemesis Gravidarum
Dry mouth (xerostomia) can worsen both caries and gingivitis.
Management
- Drink water often in small amounts. Eliminate sugar containing beverages or limit to once daily and with meals.
- Minimize snacking on simple carbohydrates (such as chips and crackers) and sweets and replace with fresh foods, whole grains, and dairy.
- Brush twice daily with a soft toothbrush using a fluoride-containing toothpaste and floss daily.
- Use fluoride rinse nightly.
- Use xylitol-containing products such as gum or lozenges after meals.
Gastroesophageal reflux and Hyperemesis gravidarum are both common in pregnancy and can cause enamel erosions.
Management
- After vomiting, rinse mouth with 1 tsp of baking soda dissolved in 1 cup of water.
- Avoid brushing too firmly or immediately following vomiting.
- Small meals with healthy food choices may minimize nausea and vomiting.
Erosions of the lingual sides of the lower incisors due to excessive exposure to gastric acid in a patient with severe GERD. Mandibular tori are also present.
