Custom Whitening trays should fit snugly and tightly against your teeth, with a comfortable fit that doesn't feel too loose or too tight, essentially mimicking the shape of your teeth and gums while staying in place without needing to hold them with your fingers when gel is applied; ideally, custom-made whitening trays will provide the best fit to ensure maximum effectiveness and minimize gum irritation.
