Do you have tooth discoloration that won’t go away, even when you brush and floss every day? Have you tried external whitening kits but haven’t gotten the results you want? If so, you’re not alone. Many people hide their smiles because they’re embarrassed, but the good news is that there is hope!

With internal bleaching in Rockville, MD, you can whiten a tooth from the inside out if it is discolored from a root canal or injury.

But how does internal bleaching compare to regular whitening?

What Is Internal Bleaching?

If you have a tooth that looks dull or discolored no matter what you try, internal bleaching could be a viable treatment option. Internal bleaching targets the stains inside your tooth. For this procedure, we remove some of the material used for your root canal treatment and replace it with a whitening solution.

This special solution breaks up the larger, darker molecules into smaller molecules, making them appear lighter in color. In just a few weeks, your discolored tooth could be a thing of the past. And once the whitening solution is done working its magic, we’ll place a new filling to protect your tooth.

How Is Teeth Whitening Different?

When you visit our office for a consultation, we’ll explain all your cosmetic options and answer your questions before creating a treatment plan.

Here are some of the ways internal bleaching differs from teeth whitening:

  • Internal bleaching works from the inside out, and teeth whitening works from the outside in.
  • Internal bleaching is usually reserved for a single tooth, while teeth whitening is often used to whiten all your teeth.
  • Internal bleaching is recommended after tooth trauma or root canal therapy, but teeth whitening combats extrinsic stains caused by certain foods, drinks, and tobacco.

Sometimes teeth with healthy outer enamel darken or become discolored, believe it or not, from the inside out!

This happens after trauma, previous root canal treatment, or due to internal staining within the tooth structure. Standard whitening treatments, even professional-grade ones, may do little for this type of discoloration. In these cases, internal tooth bleaching can be an effective way to brighten a single darkened tooth and restore a more even-looking smile.
