How well your new crown fits has everything to do with an accurate impression. Peridex helps get your gum tissue in good shape and insure a great impression.
Yes, it tastes bad and can stain your teeth temporarily, but it’s a small price to pay for a crown that will serve you well for years and years to come.
Don’t throw that Peridex out after your crown is seated! It works great around the house for those pesky pizza burns and ulcers that pop up from time to time.
In short, Peridex isn’t the devil, it just tastes like it.
