It's normal to notice more saliva than usual when you first start using iNAP. The oral interface is a new sensation in your mouth, and your mouth naturally produces more saliva in response to anything new it detects — just like it does when you first try a mouth guard or retainer. As you keep using iNAP, this extra saliva production typically decreases on its own.

A few things that can help in the meantime:

• Build up gradually during the day. Wear the oral interface while awake and sitting up — reading, watching TV — before using it overnight. This lets your mouth get used to it without the added challenge of also trying to fall asleep.
• Swallow periodically while maintaining the seal. You don't need to remove the device to swallow saliva normally.
• Try the other oral interface size. If one size feels like it's triggering more of a foreign-object sensation, the other size (I07L or I07H) may feel more comfortable for your mouth shape.
• Adjust the flow setting in the iNAP app. A higher flow setting can help clear any liquid out of the tubing more quickly if you notice gurgling or pooling.
• Stay reasonably hydrated during the day and avoid very large amounts of liquid right before bed, which can add to overnight saliva volume.

If excess saliva continues well beyond the first couple of weeks, or if you notice the oral interface discoloring or degrading faster than expected, please reach out to our customer care team.
