Supersmile vs SNOW

Some products rely solely on these ingredients, while others add LED lights to supposedly speed up the process (though the jury is out on whether these lights provide a noticeable difference). The next thing to know is how these whiteners are applied to your teeth.

One of the most well-known application methods is whitening strips. These thin, flexible strips are coated with a whitening gel and adhere directly to your teeth. They're one of the most affordable and widely available options, but since they're a one-size-fits-all solution, they might not reach every part of your teeth evenly.

You may also consider whitening toothpaste or rinses. These are the least expensive options, using mild abrasives or low concentrations of peroxide to gradually whiten over time. However, they won't give you dramatic results.

The most common approach we've found for DIY teeth whitening are gel and tray systems. These kits use a peroxide-based gel applied to a tray that fits over your teeth. Some are pre-formed, while others allow for a more custom fit. While the ready-made trays are often less expensive, a major downside of one-size-fits-all whitening trays is that they don't conform perfectly to your teeth. This can lead to uneven whitening, wasted gel, or even gum irritation if the whitening solution seeps out. If you already use a retainer or a clear aligner (like Invisalign), you might be able to use it with a whitening gel instead of buying a separate system. A custom-fit tray holds the gel against all the surfaces of your teeth, ensuring a more even and efficient whitening process.

Ready to get your brightest, whitest smile but not sure where to start? Here are a few ways you can decide which option will be the best for you:

• Effectiveness. Does the product contain a high enough concentration of peroxide for noticeable results? What do users say about how quickly they saw their teeth get whiter?
• Comfort. Is the formula gentle enough to avoid gum irritation or sensitivity? How often do customers say that they needed to take a break from using the teeth whiteners because their teeth started to feel sensitive (especially to hot/cold foods and drinks)?
• Customization. Does it include a moldable tray or work with an existing retainer? Or is it a one-size-fits-all approach?
• Convenience. How long does each session take, and how many are required? Will the system disrupt your daily routine or fit right in?
• Price vs. value. Are you getting professional-level results? Will you need to buy more than one teeth whitener kit to get the smile you want?
