It’s been almost a year since I had Zoom whitening done and I love the results! My dentist sent a tray and gel home with me for maintenance and touch-ups, but I haven’t had to use it. My friend wants to try Zoom, and since mine is just sitting around not getting used, I thought why not give the syringes and kit to her? I’m thinking that should be plenty for her to get good results, and there shouldn’t be any problem with her using it, right? — Trixie

Trixie,
I’m sure you were always taught you that it’s good to share, but when it comes to your Zoom take-home whitening kit, think again. Here’s why:

1. The gel could be expired. Most whitening gels are good for about a year, and if you’ve had it that long, who knows how long your dentist had it before prescribing it to you. It also depends on how and where you stored it (in the fridge vs. a warm place, like your bathroom).  A good indication is it’s color —  if cloudy or white, it’s definitely no good. And even if it’s still clear, there’s no guarantee it will be effective because of age.
2. Your friend’s current dental state. If she hasn’t see a dentist recently for a cleaning, it can affect the whitening results. Also, any fillings or crowns will not respond to whitening — so if she has dental work on any teeth that show when she smiles, she will definitely be disappointed.
3. Your trays will not fit anyone else. Your dentist took impressions of your teeth to make a tray just for you. Even if your friend thinks yours sort of fit her mouth, ill-fitting trays cause unevenness and splotching and the gel can ooze onto her gums and cause irritation.

It’s always fun to share with friends, but stick to clothes or your best-kept secrets. If you want to be a good friend, encourage her to visit her dentist and have a custom kit made just for her to ensure she’s smiling in the end.
