When you meet someone, chances are that the first thing you notice when they speak is the colour of their teeth. Since oral hygiene is crucial, we occasionally whiten our teeth in case there is a noticeable change in colour. Because of some reasons, the colour of our teeth changes and they consequently become discoloured. Here are some of the reasons teeth get discoloured:

Smoking:

Nicotine turns yellow when it’s exposed to air. Smoking it stains your teeth very fast. Drinking/eating habits: some foods and drink such as wine, soda or even coffee are major culprits in teeth discolouration. Many people on teeth whitening reviews stated this as their biggest weakness.

Aging:

As time goes by, the enamel thins and becomes yellow.

Poor dental hygiene:

Not brushing teeth regularly causes plaque buildup. Although people claim that a lot of solutions work in whitening teeth, the American Dental Association (ADA) says that only carbamide peroxide and hydrogen peroxide are the only solutions that work. However, since teeth whitening at the dentists can be expensive, people opt for a home teeth whitening kit which is just as efficient but a lot cheaper.

We have conducted in-depth teeth whitening reviews and come up with things everyone should look at before purchasing these kits.

Ingredients clearly labelled

The product needs to have one of the above-mentioned peroxides as an active ingredient which should be clearly labelled. Toothpaste that claims to whiten teeth only work on the surface stains. If you can’t confirm the active ingredients, don’t buy it.

Safe peroxide levels

Although the peroxides are the active ingredients, they need to be at safe levels but also these levels need to be safe. The ADA, the concentration of Hydrogen peroxide should only be used in concentrations not surpassing 10%. As for the carbamide peroxide close to 35% is safe. However, beyond these points, you are going into professional grade which should only be used by a trained professional.

Ease of use

Results are usually determined by how consistently you use the product. Since most treatments require about two treatments per day, you need to find one that is simple to apply so that you don’t feel lazy and skip a session.

Teeth whitening reviews have also shown that it all boils down to personal preference since some methods such as trays are messy, uncomfortable and tasted weird. Be sure to follow the guidelines above and you will never go wrong.
