Best Teeth Whitening Gel • Reviews & Buying Guide (January 2020)

If you have used teeth whiteners in the past, or had your teeth whitened professionally, it is likely that you already have the mouth trays.

This means that there is little point paying for them again when all that you need is the gel to get your teeth white again.

As we get older our teeth will be exposed to more and more things that lead to staining – and which ordinary, everyday brushing can’t help with, even when we use a tooth whitening toothpaste, a teeth whitening pen, or a natural teeth whitening method.

The answer is very often teeth whitening gels that are used with a mold, or tray, to hold them in place.

Luckily, it is possible to purchase teeth whitening gel for trays as a refill for the trays we already have – making home teeth whitening even more economical.

Frequently Asked Questions

Can I use these gels without the mouth trays?

These are refills for people who already have mouth trays (sometimes called thermoforms).

No, these are refills for people who already have mouth trays (sometimes called thermoforms). These are available in other teeth whitening kits for people who have never tried whitening their teeth using this method before.

The trays mold to your teeth after they have been immersed in hot water, so you get an even coverage of the formula onto your teeth. Sometimes an LED light is also used to speed up the process so you get the result you are after much quicker. If you were to use these whitening gels without the molds it is likely that you will get an uneven effect that would look worse than before you started.

Is there an expiration date on teeth whitening gels?

Something to be aware of is that some teeth whitening gels are only suitable for use a short time after they have been opened.

As with many things, yes there is – and this will be displayed somewhere on the packaging so you will know exactly how long you have got to use your teeth whitening gel for trays.

Something else to be aware of is that some teeth whitening gels are only suitable for use a short time after they have been opened. The literature you get with your whitening gel will tell you how long this is, but sometimes it is as short as one week. If you are not sure, check out the manufacturer’s website or give their care-line a call.

Is sensitivity to teeth whitening gels permanent?

If you use a gel that has hydrogen peroxide in it, then your gums may be bleached for a little time if they are exposed to it.

Fortunately, no it isn’t. Sensitivity can occur after any teeth whitening process, but if you make sure that you don’t get any of the product onto your gums, the chances of you suffering from this will be reduced. If you use a gel that has hydrogen peroxide in it, then your gums may also be bleached for a little time if they are exposed to it.

If you do suffer from sensitivity, then don’t use your teeth whitening gel on consecutive days – leave a gap of three of four days in between times. You should also use a toothpaste that has been formulated for sensitive teeth.

In Summary

Take advantage of the money saving aspect of teeth whitening gels for trays if you already have mouth trays from earlier whitening sessions.

That way you can keep your clean, bright and white teeth as they should be – at a fraction of the price!
