The Most Common Causes of Discolored Teeth
“My child’s teeth are discolored. What does this mean?”
Tooth discoloration happens for a variety of reasons, which generally belong to one of two categories:
- External—where the discoloration is more superficial, on the enamel
- Internal—where the discoloration is coming from within the deeper layers of the tooth (dentin, pulp)
Perhaps the most common complaint I hear in my office regarding discolored of the teeth is “No matter how hard we brush, her teeth still look yellow!”
That’s because discoloration of teeth is a natural occurrence. Permanent teeth are naturally yellower than baby teeth. When your child is in the “mixed dentition” phase, where their front baby teeth have fallen out but the baby molars remain, the contrast makes the color of the new permanent teeth especially unappealing. Once more baby teeth fall out in the back, it does not look so “yellow” anymore.
Another common cause of intrinsic discoloration is trauma.

When a tooth is bumped or injured, it can subsequently turn dark yellow or grey. Sometimes this discoloration improves over time, other times it remains. The important thing is to make sure a pediatric dentist sees your child right away to rule out a dental abscess, which is a common occurrence after dental trauma.
Plenty of people have congenital “blemishes” or spots on their front teeth like these:

This condition is known as enamel hypoplasia. It occurs due to a disturbance in the formation of the tooth, resulting in a yellowish-brown discoloration. The cause is often unknown, but can be linked to high fevers, antibiotics, or medications as an infant. Unfortunately there is no way to prevent it, but your pediatric dentist can remove or mask the discoloration!
Rarer causes of intrinsic staining include fluorosis, where too much fluoride intake causes mottled white discoloration, or the less common blue/green/grey tetracycline staining, which is an antibiotic that is not as frequently administered these days for this reason. These conditions are much harder to mask and require more involved, multi-step approaches by a cosmetic dentist.
Extrinsic stains, where an outside substance discolors the teeth, are usually removable during a cleaning.

The most common culprits of extrinsic staining and discolored teeth in older individuals include Coke, coffee, tea, and tobacco products. When seen in children, the cause can be more obscure. Frequently, children who are on multivitamins containing Iron will develop a dark stain on their teeth.
If there is no iron in the vitamin, then the staining is most likely due to chromogenic (color-creating) bacteria in the mouth that create the discoloration, staining the plaque dark brown to even “Cheeto”-orange! Fear not, a thorough professional cleaning by your pediatric dentist can remove these stains.
As always, don’t forget that thorough, regular brushing and flossing (click here for recommended toothbrushes and toothpaste) at home is instrumental in removal of daily buildup of tartar and plaque, which traps stain on your teeth.
Make sure you visit your pediatric dentist twice yearly to get the more stubborn stuff cleaned off!
