No. Custom oral appliances are medical-grade. However, we recommend using a pH-neutral cleansing tablet daily to prevent the buildup of biofilms.
Preventing drooling with sleep apnea devices involves managing the “foreign body response.”The foreign body response involves the salivary glands overproducing saliva in reaction to the new oral appliance. This temporary hypersalivation resolves within two to four weeks as the neurological pathways acclimate to the custom-fit mandibular advancement device and recognize it as a non-food object. At Enamel Dentistry Saltillo, we discuss ways to prevent drooling with your new oral appliance.
The medical term for drooling is transient hypersalivation. When a new mandibular advancement device (MAD) is placed, your autonomic nervous system reacts to this as a foreign body. Medical literature supports that a short-term side effect of MAD is salivation, dry mouth [1] (Manetta et al., 2022). Specifically, your parotid and submandibular glands that produce saliva receive a signal from the brain that there is an object in the mouth. Clinical research indicates that oral moistening disorders can be associated with MAD [2] (Raoof et al., 2024). Since the brain has spent years associating objects in the mouth with food, the brain assumes you are beginning a meal. This floods the mouth with saliva to begin the digestion process. For patients in Saltillo, our team explains this as a neurological reflex and not a flaw in the device. As your brain begins to realize the device is not food, the signal to overproduce saliva will eventually shut off.
By understanding the biology timeline of the oral cavity, you can help reduce the anxiety of drooling. Most patients follow a predictable three-stage recovery:
If you are still experiencing heavy drooling after 21 days, it may be time for a minor adjustment to your device.
While the body will eventually adjust on its own, the process can be sped up using these acclimation steps:
Understanding the difference between oral appliances is important, especially regarding fluid management.
Feature | Custom MAD | CPAP Machine | OTC sleep apnea therapies |
Fluid issue | Temporary | Chronic dry mouth | Irritation |
Neurological impact | High acclimation | Low | Low |
Maintenance level | Low | High | Medium |
Cost | ~$2,500 | ~$1,500 | ~$100 |
Durability | 3-5 years | 5+ yeas | Up to 6 months |
Investing in sleep is a big decision considering the cost. In Saltillo, custom sleep apnea devices are a medical investment that provides a high return on quality of life. At our office, we work with insurance providers to maximize the health benefits. If your insurance does not cover the full cost, we offer financing options with Sunbit and Cherry. This allows you to break the cost into manageable monthly payments. Our team believes that a dry pillow and a quiet night should not be a financial burden.

No. Custom MAD is designed to allow the jaw to rest naturally. If you are still drooling after three weeks, visit our office so that a fit adjustment can be performed.
No. Even a perfect fit can trigger hypersalivation. However, if the drooling is accompanied by pain or tooth sensitivity, the advancement level may need to be recalibrated.
