The Science Behind Teeth Whitening

If you’re interested in having a smile that is white and bright, you may be considering getting your teeth professionally whitened. And you might also be wondering how exactly teeth whitening works. Here, we’ll explain the science behind teeth whitening and discuss your whitening options here at North River Dental Care.

What's the Science Behind Teeth Whitening?

Over the years, your teeth can become discolored by things such as poor dental hygiene, teeth grinding, tobacco, and dark-colored drinks like coffee, red wine, and soda. As you age and consume foods and beverages that are sugary or acidic, your enamel (the outer layer of teeth) weakens and thins, which allows your dentin (the underlying yellow layer of teeth) to show through.

Teeth whitening agents can solve your discoloration woes by either removing surface stains from the hard shell enamel or by changing the color of the dentin. Whitening toothpastes contain mild abrasives that help remove surface stains from enamel. But to change the color of dentin and achieve a more dramatic result, your smile will require bleach-based whiteners that contain carbamide peroxide or hydrogen peroxide. These chemicals release oxygen into the teeth as they break down, making the teeth appear lighter and more like the smile of your dreams.

What Are My Teeth Whitening Options?

At North River Dental Care, we offer both in-office and take-home whitening treatments:

One-Visit Whitening

In office treatments are great for patients who want fast, beautiful results. We’ll apply a strong, concentrated whitening agent to your teeth so that you won’t have to worry about doing anything yourself or misapplying the gel. With this effective treatment, you’ll be able to see results after just one visit!

Take-Home Trays

Our custom take home teeth whitening trays are perfect for those who want control over their whitening treatments. We’ll create trays that are made specifically for your smile so that you can whiten your teeth in the comfort of your own home on your own schedule. These still deliver professional whitening results, but take a little longer than an in-office visit.

What Do I Need to Know About Teeth Whitening?

Teeth whitening is safe when overseen by experienced dental professionals, such as our expert team. We’ll provide you with instructions on how to care for your new smile and answer any questions that you may have. You might be a bit sensitive after you’ve gone through teeth whitening treatments, but that should go away after a few days.

Additionally, keep in mind that whitening results will vary from person to person, and results can last anywhere from six months to several years. For optimal longevity, practice good oral healthcare habits. Brush your teeth twice a day for two minutes each time, floss every day, avoid tobacco products, drink plenty of water, and limit your consumption of staining foods and beverages, like coffee, soda, and wine.
