## Description

Product Description Directions-PREFITTING PROCEDURE: Place one tray in your mouth placing on your upper teeth. Practice sucking the air from the tray. This is the procedure you will use when you retrieve the trays from the boiling water to contour the tray to the inside surface of your teeth. Do the same procedure with the other tray with your lower teeth.BOILING WATER: Boil a pan of water. Remove the water from the heat. Place the tray in the hot water by the tab. Leave in water for 3-4 seconds. FITTING THE TRAY:Lift the tray from the water using the tab. Quickly place the tray around the teeth and perform the same sucking procedure as practiced with the prefitting procedure. To avoid gel contact with the sensitive tissues of your mouth, take small scissorsand/or nail clippers and trim your trays on the gingival line (teeth/gum line). NOTE: This product does NOT include gel. To purchase gel please see our SmileMedic storefront.

### ⭐⭐⭐⭐ 







  
  
    Great for the price
  

*by K***R on Reviewed in the United States 🇺🇸 on May 23, 2020*

Average , will shrink drastically if you put in boiling water

### ⭐⭐⭐⭐ 







  
  
    Couldn't Get It to Mold, But Still Good Trays
  

*by K***L on Reviewed in the United States 🇺🇸 on June 19, 2016*

Everything was received, but the mouth trays weren't really thermoforming. I followed the instructions and they didn't even budge. Even so, they still function, just less snugly.

### ⭐⭐⭐ 







  
  
    Works okay enough
  

*by A***0 on Reviewed in the United States 🇺🇸 on June 8, 2017*

Works okay. Doesn't fit as close up to my teeth as I'd like, but it keeps my whitening gel in enough to get the job done
