What is at professional tooth whitening using dental peroxide?

It is a professional treatment that gets your teeth whiter and the product is used in the comfort of your own home. The product used is called dental bleach or dental peroxide and the active ingredient is either carbamide peroxide or hydrogen peroxide.

Fact: You can only use dental peroxide to make teeth whiter. Products that do not contain dental peroxide will NOT get your teeth whiter.  Products sold on the high street or in chemists that do not contain peroxide can only remove surface dental stains not deep dental stains. It is when you remove deep dental stains your teeth become much whiter.

What is the difference between carbamide peroxide and hydrogen peroxide?

A very popular question asked by the public and dentists. Carbamide peroxide is a by-product of hydrogen peroxide. When carbamide is used in the mouth it breaks down to hydrogen peroxide. Carbamide peroxide is the most popular selling product as it is more gentle and is still as effective as using hydrogen peroxide.

How should I store my dental bleach when it arrives in the post ?

Always keep the dental bleaching gel products in the fridge or cool place. Please always keep your dental bleach products aways from small children.

How does dental peroxide work ?

It works by oxygen as soon as you use dental bleach you will notice it "bubble and a froth and will start to activate" this is how the oxygen treats the deep dental staining.

When you brush your teeth toothpaste you can only remove the surface staining it takes dental peroxide to remove "deep enamel" staining. You will see hundreds of whitening toothpastes in the supermarkets and even whitening sytems but they do contain "dental peroxide" so it is impossible they can remove deep dental stains they only remove surface staining.

How to use the teeth whitening gel product ?

EASY. You SIMPLY apply a small dose of gel into the mouth trays and wear the mouth trays for 30 min's each day for 14 days. (You apply an even stroke of gel to the inside of the trays that will cover your teeth) Do not overfill the mouth trays with gel. (Less gel is better than too much gel). Keep gel stored in the fridge. If you get any gel on your gums during treatment simply use a wet tissue or cotton bud to remove it.

Is it safe to use teeth whitening on dental fillings, veneers, crowns and bridges ?

Yes. You can even use dental bleach with gold crowns. Do remember that dental bleach will not whiten fillings, crowns, bridges or veneers as it will only whiten natural teeth.

Is there anything I can do to make the whitening more effective?

Yes. Simply pat the teeth dry with a tissue prior to bleaching.

What if I swallow the gel?
The gel will not harm you in the quantities swallowed as it is non-toxic. We do not recommend sleeping wearing teeth whitening trays in your mouth.

What about side affects?

Minor temporary sensitivity can happen during treatment but this can be prevented by using the Happysmile brand.

Should I brush teeth before use?

Do not brush your teeth immediately before whitening. After whitening simply use a very "soft tooth brush" and be gentle and remove the gel.

How should I store my teeth whitening gels?
Teeth whitening gels should be refrigerated or stored in a cool environment.

How much gel should I use in the trays?
Simply use enough gel so that it whitens your teeth and apply to the inside of the mouth trays the side that covers the teeth. Simply use an even stroke of gel around the trays.

Is teeth whitening permanent?
Yes! Whitening your teeth by this method is permanent. However, depending on the amount of coffee, tea, wine and other stain causing food you consume re-staining may occur.

When should I top up my treatment?

You may wish to use a touch up every 3 months or when needed.
