Frequently Asked Questions (FAQ’s)

Can I swallow saliva when using the whitening strips?

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 gets to work, this is normal.

Can the whitening strips be in contact with my gums?

Yes, but such contact should be minimised to avoid gum irritation.

What if I experience tooth sensitivity or gum irritation?

It is not uncommon to experience tooth sensitivity and / or gum irritation whilst whitening your teeth. This is temporary and NOT harmful. To alleviate symptoms it may be sensible to whiten your teeth on alternate days, until you have used all of the strips. If the problem persists, discontinue use and consult your dentist.

White spots sometimes appear on my teeth after whitening, should I be concerned?

No. These white spots are temporary; they are not harmful and will disappear within 24 hours.

Should I brush my teeth before / after use?

Ideally your teeth should be clean when applying the whitening strips. However, do not use immediately after brushing your teeth because brushing can cause gum irritation. You may brush your teeth after use to remove any residue from the strips.

Why is this product only available through my dentist?

WhiteWash Professional Whitening Strips are only available on prescription from your dentist because your teeth need to be examined to ensure they are suitable for whitening. Whitening strips are not a substitute for regular dental care.

Are whitening strips suitable for everyone?

Though the whitening strips are non-harmful to the human body, it is advised that children under the age of 16, pregnant women, and those sensitive to hydrogen peroxide should not use them. Patients with teeth sensitive to cold, heat or acid, or those who suffer from oral ulceration should discuss this with their prescribing dentist before undergoing a course of whitening treatment.

Will the strips affect my dental work?

The whitening strips will ONLY whiten natural teeth; they will not affect caps, crowns, veneers, bridges, fillings or dentures. Do not use on loose teeth, temporary fillings or Orthodontic appliances. Consult your dentist if you have any dental concerns.

When will I see results?

After using the strips for 3 days you will start to notice your teeth become lighter. For best results finish your prescribed course of treatment.

Will I get even results?

Each strip contains the exact amount of whitening gel to effectively whiten your teeth. Each strip should be positioned across the teeth and gently pressed into place, aiming to get maximum contact with all of your visible teeth. This will ensure even spread of the whitening gel.

How long do the results last?

This depends on personal dietary and smoking habits. After the use of whitening strips your teeth will gradually discolour. To keep your whiter smile for longer it is best to avoid smoking and consuming foods / drinks that stain your teeth e.g strong coloured foods / red wine / coffee etc. To maintain your white smile it is advised to use one box of WhiteWash Professional Whitening Strips every 6-12 months, or use 1-2 strips on a monthly basis.

How do whitening strips differ from trays?

As well as being more cost-effective than trays, WhiteWash Professional Whitening Strips are more comfortable, less bulky, and allow you to whiten on the go. Whats more, each strip already contains the optimum amount of whitening gel so its less hassle for you and helps to ensure you achieve an even white smile.
