Nausea isn't related to retainer, however initially you may feel slight gagging as it's something new. But if it persists beyond a few days visit your dentist to get the retainer checked out. Once you get used to it which is mostly within 5 to 7 days, you shouldn't be feeling any gagging sensation. If you do, your retainer needs to be corrected for any extensions into the soft palate areas.
