Your teeth hurt after vomiting because of the strong stomach acid that comes into contact with them. This acid erodes the enamel, which is the protective outer layer of your teeth, leading to sensitivity and pain.
How Stomach Acid Damages Teeth
-
Enamel Erosion: Stomach acid has a very low pH, making it highly acidic. When it washes over your teeth during vomiting, it begins to dissolve the enamel.
-
Dentin Exposure: Underneath the enamel is a layer called dentin. Dentin is softer and more porous than enamel. When enamel is eroded, the dentin becomes exposed, making your teeth more sensitive to temperature changes, sweet foods, and even air.
-
Increased Sensitivity: The exposed dentin contains tiny tubules that lead directly to the nerve of the tooth. This allows external stimuli to trigger pain signals more easily.
Factors Affecting the Severity of Tooth Pain
The extent of tooth pain after vomiting depends on several factors, including:
- Frequency of Vomiting: Frequent vomiting, such as in cases of bulimia or hyperemesis gravidarum, leads to more significant enamel erosion and increased sensitivity.
- Acidity of Stomach Contents: The pH level of stomach acid can vary. More acidic stomach contents can cause greater damage.
- Oral Hygiene: Good oral hygiene practices can help to mitigate the effects of acid erosion.
- Time Since Last Dental Checkup: Regular dental checkups allow dentists to identify and address early signs of enamel erosion.
What You Can Do
Here are some steps you can take to minimize tooth pain after vomiting:
-
Rinse with Water or Baking Soda Solution: Immediately after vomiting, rinse your mouth thoroughly with plain water or a solution of water and baking soda. Baking soda helps to neutralize the acid.
-
Wait Before Brushing: Avoid brushing your teeth immediately after vomiting, as this can further erode the enamel while it's softened by the acid. Wait at least 30 minutes to an hour.
-
Use a Soft-Bristled Toothbrush: When you do brush, use a soft-bristled toothbrush and a gentle technique.
-
Use Fluoride Toothpaste: Fluoride helps to strengthen enamel and protect against acid erosion.
-
Avoid Acidic Foods and Drinks: Limit your intake of acidic foods and drinks, such as citrus fruits, sodas, and fruit juices, as they can further damage your enamel.
-
See Your Dentist Regularly: Regular dental checkups are essential for detecting and treating enamel erosion early on. Your dentist may recommend fluoride treatments or other measures to protect your teeth.
-
Address the Underlying Cause of Vomiting: If your vomiting is frequent or chronic, it's important to address the underlying medical or psychological condition.
