What's the Difference Between Intrinsic vs. Extrinsic Teeth Stains?

A brite, white smile is often associated with health and it has been shown that it can boost a person’s confidence.

But before you head out and buy your own at-home whitening kit, you should know how these teeth whitening products actually work.

For instance, did you know that there are two types of stains that can occur on teeth? Well, if you didn't know this then sit back and relax for this short read.

In this post, we will quickly discuss the difference between:

  • Intrinsic, or internal, stains
  • Extrinsic, or external, stains

And we’ll also address how Dr. Brite’s Teeth Whitening Pens work to tackle both stain types.

What Are Intrinsic Teeth Stains?

Intrinsic stains can occur deeper within the tooth rather than on the outermost layers. In a way, you can think of intrinsic stains as internal stains. Here’s some of the causes for these deeper stains:

  • Tiny dental fractures or cracks in the tooth enamel, which allows stains to penetrate deeper into the tooth
  • Using tetracycline antibiotics, which can turn your teeth gray
  • Bleeding within the tooth or a pulp infection
  • Tooth decay or weakened tooth enamel
  • Using too much fluoride
  • Genetics, which causes a small percentage of people to have purple, gray, or orange stains (Dr. Q Dental)

What Are Extrinsic Teeth Stains?

Extrinsic stains, on the other hand, stain the outer layer of the tooth enamel and are commonly caused by foods and dark beverages. Here's a short list of what can also cause external stains on your teeth:

  • Coffee and tea
  • Wine
  • Dark sodas
  • Rich, pigmented fruits like blueberries
  • Pigmented vegetables like carrots or beets
  • Brightly-colored hard candies
  • Smoking or chewing tobacco (Woodlane Dentistry)

How Do Dr. Brite’s Teeth Whitening Pens Work?

So, Dr. Brite has two types of whitening pens that can specifically target the two types of teeth stains we mentioned. Our powerful Natural Teeth Whitening Pen with food-grade hydrogen peroxide is perfect to prevent extrinsic stains from settling onto your teeth.

So, if you’re not sensitive to food-grade hydrogen peroxide, you can use the Dr. Brite Natural Teeth Whitening Pen after you have had a cup of coffee, a glass of wine, or a smoothie bowl with colorful fruit. In fact, you can use our teeth whitening pens two to three times a day and they are completely safe to swallow. You can expect teeth to look two shades brighter in just two days with our Natural Teeth Whitening Pen.

Now, if you have a sensitivity to food-grade hydrogen peroxide or if you prefer to not use products with this ingredient, we offer a Peroxide-free Teeth Whitening Pen that uses coconut oil, which can gently and gradually whiten teeth on a intrinsic level. If you happen to have sensitive teeth, the Dr. Brite Peroxide-free Teeth Whitening Pens can actually help desensitize teeth with continuous use thanks to the coconut oil in this formula. Now, you can expect teeth to look four shades whiter in seven days when using our peroxide-free whitening pen two to three times a day.

So, if you have ever been curious about teeth whitening or if you’re curious about Dr. Brite’s teeth whitening pens, we hope this gives you more insight into what causes teeth stains and why we have two different formulas and how they function.
