Yes, but such contact should be minimised to avoid gum irritation.
It is not uncommon to experience tooth sensitivity and/or gum irritation when whitening your teeth. This is temporary and NOT harmful. To alleviate symptoms, it may be sensible to whiten your teeth on alternate days, rather than daily whitening. Brush with toothpaste for sensitive teeth after applying Bliss Whitening Strips to help with sensitivity and remember to gargle with mouthwash daily to keep your gums healthy and happy!
As well as being more cost-effective than trays, Bliss Whitening Strips are more comfortable, less bulky, and allow you to whiten on the go. What's more, each strip already contains the optimum amount of whitening gel so it's less hassle for you and helps to ensure you achieve an even white smile.
Yes, you can. It is perfectly safe to swallow saliva when using the whitening strips. You may also notice a foaming reaction as the hydrogen peroxide works its magic – this is completely normal.
Definitely! Regular treatments and top-ups are what will allow you to keep your amazing results.
