Call for more information. It began in my freshman year of high school when I was finally saying goodbye to my junior-high-brace-face days. I was ready to be rebirthed into my new, popular-girl identity, but the braces had left behind yellow teeth that kept me on house arrest. So, my mom finally obliged and had my teeth professionally whitened the summer before entering high school.

After just a few laser zaps, my teeth were pearly white beacons of light. I was hooked. This time, when I went in for my whitening, the orthodontist measured my teeth shade as B1. So, my teeth were already pretty white.

But, of course, my whiteorexic self was determined to go even lighter. To keep my mouth open for the duration of the treatment, she indelicately shoved a rubber wedge into my mouth that felt like leg stirrups at the gyno.

Then she covered my receding gums with a hardening gel that would keep the bleach just where you'd want it: on the enamel. The result is chompers that can be up to eight shades brighter — in just 45 minutes. All you have to do is lie there and not freak out. But, inevitably, I started getting antsy, jerking around and trying to read my email on my iPhone around the UV contraption.

But, it wasn't until I felt my first "zing" when I decided to call it quits. The zing is like a tiny zap of pain that runs through your teeth for a few seconds, expanding in pain, until it disappears as quickly as it came. My teeth were glow-in-the-dark white two full bleach shades, technically , and I was paying for it with zings that continued on through the rest of the day and night.

I was popping Advils like they were little bits of candy, but the onslaught of zings didn't stop till the next day. But, not until my teeth are in serious coffee-stained need. The product uses "LiquidStrip Technology," which holds the whitening agent to the teeth while you sleep. The whitening gel forms a LiquidStrip coating on the teeth that works to remove stains and loosen stain-causing buildup.

In the morning, users brush the LiquidStrip coating and stains away. Night Effects was found to lighten teeth from two to five shades, according to a dental shade gauge for teeth. But testers noted that the gel felt "goopy" after application. Britesmile and Zoom! The other top alternatives were in-office bleaching at Britesmile and Zoom! A special light activates hydrogen peroxide gel applied to teeth 15 percent of hydrogen peroxide in the Britesmile gel and 25 percent for Zoom! Both concentrations are lower than some home whitening gels, which have 35 percent to 50 percent.

Before we answer the question, a brief reminder … You can get these whitening products from a dentist or OTC. These products work proportionally to the concentrations of the bleaching agents hydrogen peroxide or carbamide peroxide present. The good news is that there is evidence they are better than no treatment at all or a placebo.

Though, most of the studies were short-term and financed or run by the manufacturers. Hence, the likelihood of bias remains high. As a general rule, one can say can they lighten your teeth by 1 or 2 shades, after several days of use.

For instance, paint-on whitening gels can lighten your teeth by 1 or 2 shades. Likewise, whitening washes usually take 3 months to lead to 1 or 2 shade improvement in tooth color.

The same is true for tray-based methods. You can observe a lightening effect of shades within a few days. They are not the open sesame to a glitterings smile. Their effect on the tooth color is also in the order of one or two shades. Although, they are better than standard toothpastes because they can remove or prevent surface stains. A review article in the Journal of the ADA concluded saying that: To ensure you choose a safe and effective dental product, select those that have the ADA seal of acceptance.

As explained before see Which are the best whitening strips? All this is interesting, but for how long should I use the trays at home?

A few days, a few weeks or longer? Each patient is undoubtedly unique. While some may not need them at all, others may need longer treatment periods. So, can you conclude from the above that — as long as you continue using trays with gel — then prolonged results are forever?

If instead, you avoid or dramatically reduce these sources of staining, you may not need another whitening treatment for at least 6 to 12 months.
