What is the most common oral side effect experienced by post gastric surgery patients?

The most common oral side effect experienced by post gastric surgery patients is dental erosion. After undergoing gastric surgery, such as gastric bypass, individuals may experience changes in their body's ability to absorb nutrients and a potential increase in gastric acidity. This can lead to acid reflux or gastroesophageal reflux disease (GERD), which exposes the teeth to higher levels of acid.

Over time, this acidic environment can result in the erosion of tooth enamel, making the teeth more susceptible to decay and sensitivity. Dental erosion is particularly problematic because it can lead to significant dental issues if not addressed, such as increased risk of cavities and changes in tooth structure.

While conditions like tooth decay, dental sensitivity, and gum disease can also occur after surgery, they are not as directly correlated with the physiological changes that result from gastric surgery as dental erosion is. Hence, dental erosion emerges as the most prevalent oral complication for these patients.
