And the kits worked. I became obsessive, building up a stash of products.
The dark side of white teeth: DIY whiteners can be dangerously addictive | Daily Mail Online
One of the first I bought required you to squeeze whitening gel into a gum shield and wear it for 20 minutes; this seemed inconveniently messy. Then a friend who lives in Los Angeles introduced me to a product which promised whiter teeth in five minutes. You peeled a gel-infused strip out of its packet and stuck it on your teeth.
Moments later, your smile would practically glow fluorescent. The faster the effects, the better, as far as I was concerned.
Certain products irritated my gums, but I chose not to investigate. In fact, the reason these products were so effective was because they were damaging my teeth. The acid can cause chemical burns on the gums, further increasing the risk of losing teeth.
The dark side of white teeth: DIY whiteners can be dangerously addictive
They become stained easily by food and drink and turn brown. Most DIY products use hydrogen peroxide — this works by penetrating the porous enamel and oxidising stains the oxygen produced by the process reacts with the discoloured material on the teeth and chemically changes it. So, if the concentration of hydrogen peroxide is too strong, it can burn the soft tissue or even cause irreversible gum recession, exposing the root of the tooth and causing sensitivity.
If you ingest a significant amount of the hydrogen peroxide gel, it can also burn the throat, stomach and gut.
While many products contain hydrogen peroxide, others, such as toothpastes, use abrasive ingredients such as sand to polish off the stains. So no chemical burns or gum recession then. How could that be? The legal percentage of hydrogen peroxide permitted in these kits is 0. In other words, many of the products we are buying will not make our teeth permanently whiter, and are abrasive enough to cause harm if we use them year after year.
Meanwhile, in one of my kits bought in the U. So you use it again, and again. In at least one kit the ingredients contain chemicals such as carbamide peroxide that react with saliva to produce hydrogen peroxide. But if DIY is a worry, what about High Street salons offering teeth whitening as a cosmetic treatment performed by a beautician? However, there are no studies supporting this method in removing deeper stains.

In most cases, this is bunk. The general recommendation is to use over-the-counter whitening products up to two times a year. Using whitening products too often can lead to increased tooth sensitivity or white spots — this is natural and due to certain areas of your teeth that have a lack of calcium also known as hypocalcification. Excessive whitening can make the spots more prominent.
What are some other teeth whitening tips? The best way to preserve your whitening results is to avoid stain causing products such as coffee, red wine, and dark colas. If skipping your morning coffee is too difficult, just remember to avoid brushing your teeth or using whiteners right after — it can do more harm than good.
Acidic food and drinks soften your teeth, and Dr. To cut down on sensitivity during the whitening process, you can try brushing with Sensodyne Pronamel toothpaste recommended by a few dentists we spoke to. You can always come back to whitening later or consult a dentist to see what other options are available. What about whitening toothpaste or mouthwash? Put simply, whitening toothpastes and mouthwashes cannot remove deep stains as well as whitening treatments.
Each of your teeth is made up of multiple layers. First, a layer of enamel offers defense for the crowns of your teeth, the part that exists above the gum line.
But over time, the stuff you eat and drink — berries, red wine, coffee — forms another layer, the pellicle layer, on top of your enamel. Over the years, the pellicle layer may begin to penetrate the porous enamel layer.
