Speed selection

• The MEGASONEX® ultrasonic tongue scraper can be used in one of three modes:

1. Ultrasound plus sonic vibration
   • Ultrasound at 1.6MHz
   • Sonic vibration at 18,000 or 9,000 movements per minute
2. Ultrasound only
   • Ultrasound at 1.6MHz
   • No sonic vibration
3. Manual only
   • No ultrasound
   • No sonic vibration

How to use

1. Mount and fasten the scraper onto the MEGASONEX® handle.
2. Select your optimal speed as you would for the toothbrush.
3. Place the scraper ¾ the length of the tongue on either the left of right side of the tongue, near the back of the throat. Gently but firmly move it towards the tip of the tongue. This should take 1-2 seconds. Repeat a few times, rinsing the scraper between each stroke.
4. Do the same for the other half of the tongue.
5. Turn the scraper at a 45° angle and clean the middle part of the tongue.
6. In the end, if desired, turn the scraper 90° to the tongue to cover a wider cleaning area.
7. Gently repeat the motion on each side of the tongue.
8. Clean and dry after each use. Normal soap and water are sufficient, as long as the scraper is thoroughly dried after each use.

• Dispose after several months or when the working edge of the scraper appears dull.
• Pressing harder on the tongue does not ensure better removal of the biofilm. In fact, it could do more harm than good. It is far better to clean the tongue more often than to clean it with excessive pressure that can damage the tongue and lead to bleeding, infection and other issues.

Restrictions and limitations

• The scraper in ultrasonic mode has not yet been tested on pregnant women, diabetics and people with sub-dermal electrical devices such as pacemakers. In these cases, you should consult your physician before use.
• The scraper should not be used with any other device or tool aside from the MEGASONEX® ultrasonic brush handle.
• Try to avoid the very back of your tongue, which houses the circumvallate papillae (6-12 3-4 mm discs). They are involved with digestion and should not be disturbed. This applies to all forms of tongue cleaning.
• As with a toothbrush, do not share your tongue scraper with others to help avoid cross contamination.
• Be sure to wash with soap and water, like you would a toothbrush, before first use. All oral hygiene devices are usually manufactured in clean but non-sterile conditions. An extra wash before first use is a good commonsense practice.
• Some individuals have a heightened gag reflex. As with any device going into the mouth, with time and repeated gradual shallow use, this reflex could be reduced. These individuals should start cleaning just the front part of the tongue, then, with practice, slowly increasing the cleaning area over a period of weeks or months.
