Brazilian researchers have at least come up with a set of tongue and mouth exercises that may help individuals whose snore is due to tongue/mouth factors. Best of all... it's free and at least according to their study population of 39 patients (20 control; 19 study), there was a significant decrease in frequency of loud snoring by 36% and the total power of snoring by 59% after 3 months of exercising!
It can't hurt to give it a try. The improvement is thought to occur due to increased muscle tone allowing the airway to remain open during sleep.
Here are the 6 exercises to do every day (photos courtesy of my dad... thanks dad!):
Exercise #1: Push the tip of the tongue against the roof of the mouth and slide backwards. Perform 20 times.
Exercise #2: Suck the entire tongue upward against the roof of the mouth (like you are about to make a cluck sound). Perform 20 times.
Exercise #3: Force the back of the tongue against the floor of the mouth while keeping the tongue tip pressed against back aspect of the lower teeth. Perform 20 times.
Exercise #4: Elevate the soft palate and uvula up and down. Perform 20 times.
Exercise #5: Press your cheek muscle against your finger. Perform 10 times on each side.
Exercise #6: Alternate bilateral chewing and swallowing using the tongue against the palate without perioral contraction whenever feeding.
Alternatively, playing a wind instrument like the didgeridoo has also been found to be helpful.
