The shape of the mouth tape is important as it needs to conform well to the contours of the mouth. A curved shape can better fit the natural shape of the lips, ensuring a more secure and comfortable seal. If the tape is too straight, it may not adhere properly at the corners of the mouth, increasing the likelihood of air leakage or the tape coming off. The size of the tape also matters. It should be large enough to cover the mouth adequately to prevent air from escaping through the sides of the mouth. However, if it is too large, it may be uncomfortable and may even cause skin irritation on the cheeks or chin. Some tapes are designed with a specific width that allows for sufficient adhesion while still being gentle on the skin. Additionally, the thickness of the tape can impact its flexibility and how well it stays in place. A well designed tape will balance all these factors to maximize its effectiveness in promoting nasal breathing.
