Should I brush my teeth before breath test?

It is generally recommended to brush your teeth before taking a breath test. Brushing your teeth helps to remove any food particles, bacteria, and other substances from your mouth, which can affect the accuracy of the breath test results. Additionally, some breath test devices are sensitive to even small amounts of food particles in your mouth, so brushing your teeth before taking a breath test can help ensure an accurate result.
