Have you noticed your smile slowly turning yellow over time? You might want to get rid of these stains, so you’re looking for effective, convenient solutions. During your searches, you may run into store-bought teeth whitening and professional kits. You might wonder which one is better for you in the long run, so here’s what to know and which one can give you dramatic results.

Are Store-Bought Whitening Kits Effective?

Many people like store-bought whitening kits because you can order them online or get them at your local department store. That said, these products have a diluted bleaching agent in them. The low concentration means they can brighten your teeth by a shade or two after a couple of weeks of consistent use.

You can also accidentally misuse them. The gel can get on your gums and irritate them or erode your enamel if left on too long. Items with activated charcoal or baking soda can also be trouble, so you may inadvertently increase your risk of cavities.

What’s Different About Professional Teeth Whitening Kits?

If you want a professional kit, you will need to visit your dentist. They will ensure your oral health is a good foundation and spot any dental problems before they cause complications. Once you’re cleared, you’ll apply an ultra-concentrated bleaching gel on customized trays. You’ll wear them for a set amount of time for two weeks. Afterward, you can get noticeable results with up to an eight-shade difference.

Since this treatment is tailored to you, you reduce the risk of gum contact and sensitivity. That way, you get the brighter smile you want without discomfort.

So, How Should I Whiten My Teeth?

As you might be able to guess, a professional whitening kit from your dentist is often the better, safer method. Your provider will let you know what you can expect and then get you to your goals. That way, you get the results you want without sacrificing your oral health in the process. So, while you might want to get store-bought products, it’s best to leave them out of your cart and avoid the trouble they can cause.
