3 Types of Tooth Stains and How to Remove Them

No one likes to look in the mirror and see discolored and yellow teeth smiling back at them. Everyone battles stained teeth at some point in their lives, but how you should go about removing the stains can be challenging to determine. Whitening stained teeth depends on the type of stains you have and which whitening options are best for your oral health. But there’s good news! With so many whitening options available, there’s bound to be one that will get your smile shining in no time.

Types of Tooth Stains

Extrinsic Stains

An extrinsic tooth stain is a stain on the outer part of the tooth. These stains reside on your enamel, the layer of the tooth protecting the softer part of the tooth (dentin) underneath. Even though enamel is the hardest part of the tooth, it comes in contact with everything you eat or drink and can absorb some of the pigment over time, causing a stain.

The good news is that extrinsic stains don’t move below the enamel to the inner part of the tooth, which means it’s easier to remove them!

Intrinsic Stains

Intrinsic stains happen when the sensitive layer underneath the enamel, called dentin, is stained. Dentin is naturally darker and more yellow and is exposed when the enamel is thinned or worn down from wear or inadequate oral hygiene. These stains are a little tougher to remove, but not to worry, it can be done! Most at-home techniques that do not use hydrogen peroxide or carbamide peroxide as an active ingredient will not work to remove intrinsic stains. Still, a professional whitening treatment might do the trick.

Age-related Stains

Like many things in your body, your teeth show signs of aging as you get older. You can expect to see two central changes to your teeth as you age: your dentin darkens and your enamel thins. The combination causes unwanted discoloration that, unfortunately, is out of your control. Similar to intrinsic stains, age-related staining affects the dentin of your teeth. So, it would be most effective to treat these stains with a product that uses an active whitening ingredient like hydrogen peroxide or carbamide peroxide, or a professional in-office whitening treatment.

Removing Tooth Stains

Removing Teeth Stains at Home:

Whitening Toothpaste- Whitening toothpaste is a great way to remove extrinsic tooth stains while in the comfort of your own home. Many whitening toothpastes contain mild abrasives that help to remove buildup and surface stains. Some include a whitening ingredient like hydrogen peroxide that goes beneath the surface to remove deep-set stains. Using whitening toothpaste is the easiest remedy for at-home whitening since it’s easily incorporated into something you already do (or should do) twice a day.

  • Whitening Pens- Whitening pens are an excellent whitening solution for a busy-bee on the go. It's quick, easy and doesn't leave you with a mess to clean up. After brushing your teeth, you apply a thin layer of whitening gel from the pen onto your teeth and wait to eat or drink for the amount of time suggested on the packaging. It's that simple, and it starts working right away.
  • Tooth Whitening Gel- Available over the counter and from your dentist, tooth whitening gels contain peroxide-based bleaching agents, but in higher doses than in whitening toothpaste. Since the gel has higher amounts of peroxide, you’ll need to use a tray, so it only comes in contact with your teeth, not the rest of the inside of your mouth. You can get a tooth whitening tray over the counter at a drugstore or get a custom-fit tray from your dentist. Custom trays are usually more effective and better at protecting your gums, but they can be much more expensive than over-the-counter options. Talk to your dentist about what would be the best option for you.
  • Tooth Whitening Strips- This at-home method uses whitening gel but pre-applies it to strips for easy application without a tray. Whitening strips may cause sensitivity because of the high amounts of hydrogen peroxide or carbamide peroxide, so choose carefully and make sure you're looking at the ingredients before adding them to your cart. You can pick up a pack of whitening strips at the store and follow the directions on the back of the package.

In-Office Whitening

If your teeth stains won’t budge with an at-home whitening technique, there’s no need to worry! Talk to your dentist about professional in-office whitening to remove deep stains from your teeth. Although this method is known to be the most efficient way to whiten discolored teeth, it can also be the most expensive course of action. If the price tag of a professional treatment concerns you, consider visiting a school for affordable dentistry or check to see if your area has a low-cost dental clinic that offers whitening services.

There’s no need to be afraid of flashing your winning smile. Whether at home or the dentist's office, removing unsightly teeth stains has never been easier! Talk with your dentist about what option is best for you and regain confidence in your smile.
