Does Teeth Whitening Actually Work?

“Does teeth whitening actually work?” It’s one of the most common questions that patients ask Kenneth Hill, DDS when they come in for a checkup. This isn’t surprising because today’s generation is obsessed with having a more youthful appearance.

When dentists talk of teeth whiteners, they’re talking about whitening products containing carbide peroxide. It’s a substance used to break down hydrogen peroxide on the teeth. Hydrogen peroxide breaks down those larger molecules and turns them into smaller ones to reflect more light.

The difference among the types of whiteners will depend on the peroxide level being used. In-house teeth whitening contains up to 35 percent peroxide. A custom-mold tray that is sent home consists of up to 15 percent peroxide solution.

As regards to OTC kits that you can buy, the carbide peroxide contains only 10 percent. It can whiten your teeth, as long as it carries the seal of approval of American Dental Association.

However, the teeth whitening offered by your dentists have higher concentrations of carbamide peroxide so they work faster. The results are visible within a few hours, as opposed to a few weeks of applying an OTC teeth whitening solution.

Unfortunately, applying a higher concentration of peroxide has a risk of causing bleeding gums. This is one of the reasons some dentists utilize laser whitening. You’re also at risk of experiencing tooth sensitivity. Thus, your dentist will first address your tooth sensitivity before recommending a teeth whitening procedure.

How long will the result last?

Teeth whitening actually works but the result doesn’t always last a lifetime. The whiteness of your teeth can last depending on your diet and medications. For example, if you’re fond of drinking red wine, the stains will reappear faster than you think. On the other hand, if you limit those foods or liquids that can stain your teeth, your whiter teeth should stay for about a year or so.

So, should you opt for a visit to your dentist to undergo teeth whitening or just choose an OTC whitening product?

It depends. If you wish to achieve better results, you should consider going to your dentist and have your teeth brightened by a professional. In this way, any type of dental problems can be resolved first before you undergo a teeth whitening procedure.

Now, if you wish to have a quick fix or speedier results, you should go to your dentist. In as little as a few hours of sitting in your dentist’s chair, you can have whiter teeth.

How much does it cost to have teeth whitening procedure?

It also depends on how discolored your teeth are. Laser whitening can go around $1,000. OTC whitening kits, on the other hand, can vary widely. You can have as low as $30 or as high as $300. However, just because it’s expensive doesn’t mean that the product is more effective. To be safe, you should consult your dentist first before investing in an OTC product just to whiten your teeth.
