Have you noticed stains developing on your teeth over time? The yellow tint might bother you, but there are a few different ways you can get back a bright smile at home. You may be debating between getting a whitening kit from your local department store or a professional one from your dentist. One is often better than the other, so here’s what you should know about both methods to make a confident choice.

Do Store-Bought Teeth Whitening Kits Work?

On the shelves at your local department store, there are countless over-the-counter products that promise dramatic teeth whitening results. They are accessible, so you may want to put one in your cart, but they often fall flat. The concentration of the bleaching agent in them is typically low, so using them consistently may only give a one- or two-shade difference after about two weeks.

That said, you risk misusing or overusing these items. This can lead to sensitivity or even cavities if you aren’t careful. So, these products may be harmful to your oral health in the long run.

How Do Professional Teeth Whitening Kits Compare?

Compared to store-bought teeth whitening kits, ones from your dentist have a much higher concentration of bleaching agent. This means wearing your customized trays as directed for two weeks can give you results that are up to eight shades brighter.

Better yet, your provider will give you instructions to help you avoid sensitivity and protect your enamel health. This route can be more reliable, but you can even get faster results with an in-office visit.

So, Which Is Best for Your Smile in the Long Run?

You might be able to guess which teeth whitening kit is better for your oral health. Heading to your dentist for the brighter smile you want is oftentimes much safer and more effective. You can get the dramatic results you want without the risk of developing sensitivity or cavities. While over-the-counter options may be convenient, having a visit to your provider can be the better option. That way, you get rid of the stains on your grin and get the bright look you’re after.
