Teeth Whitening

Teeth whitening refers to a variety of processes that aim to make someone’s natural teeth appear brighter and whiter. Teeth whitening methods include sanding down stains, bleaching, ultraviolet (UV) light therapy, and more.

 

Many different teeth whitening products are available, and you can try many approaches at home. You can also get your teeth whitened at your dentist’s office.

Types of teeth stains

To whiten your teeth effectively, you’ll need to choose a whitening method that addresses the type of staining you have. If you have both intrinsic and extrinsic staining (explained below), you’ll likely need to choose a whitening method that safely addresses each type.

If you aren’t sure which kind of staining you have, consider consulting your dentist. They can advise you on the type of stains on your teeth and which method might work best.

 

Intrinsic stains

Stains that are inside your tooth enamel are called intrinsic stains. Intrinsic staining is sometimes present even before your teeth erupt from your gums when you’re a kid.

These stains can result from antibiotic use, high levels of fluoride exposure, and your tooth enamel growing thinner as you age. Intrinsic staining can sometimes even be genetic, according to 2014 researchTrusted Source.

Extrinsic stains

Extrinsic stains are on the outside of your tooth. These happen due to environmental exposure to things that leave discoloration on your tooth enamel. Coffee, artificial food colorings, and smoking can all cause this type of staining.

Like intrinsic stains, extrinsic stains can also be linked to antibiotic use, based on the 2014 research above.

Who should get their teeth whitened?

Depictions of pearly white teeth on TV or in magazines have made it seem like a spotless, perfect smile is the norm. But no matter what your teeth look like, there’s no reason to ever be ashamed of your smile. You should prioritize the health of your teeth above cosmetic appearances.

Tooth yellowing can occur due to:

Access to teeth whitening treatment may also depend on your budget. Whitening products and in-office treatments are not covered by insurance. Some people may choose options that have a milder whitening effect but are more affordable, like toothpastes and mouthwashes.

People who have dental implants or veneers are not candidates for teeth whitening. Teeth whitening works on natural teeth only. Many younger people in recent years have pursued veneers to achieve a perfectly white smile, but this can be dangerous for your teeth’s health in the long run.

If you are self-conscious about your smile because of teeth yellowing and you have your natural teeth, you might want to try teeth whitening methods. But ultimately this is a personal aesthetic choice and not a medical necessity.

Consult with your dentist about what whitening options may be best for you. Always read directions on home kits and use products as directed.

It’s important to note that people with dental implants, veneers, crowns, or bridges might not be candidates for teeth whitening, depending on the location of this dental work. If it is in the back of the mouth, a person may still receive whitening. If is in the front of the mouth, whitening is not recommended.
