Most if not all of the black stains on kid’s teeth do not occur overnight; they first appears as brown or gray spots which over time turns black. These stains can be caused by either internal factors that starts on from the inside of the teeth such as tooth decay or external factors that begins from the outside of the teeth such as food/drinks stains.
And here are the most suggested causes of black stains on kids teeth by professionals, researches and parents.
What Causes Black Stains On Kid’s Teeth
- Tartar buildup
- Tooth decay or cavities
- Kind of food and drinks they eat /drink
- Dental restoration
- Excessive fluoride
- Certain medications
Poor oral hygiene like not brushing or flossing teeth properly leads to formation of plaque that if not removed, harden into tartar also called calculus that appear as black spots and stains on teeth. (https://www.webmd.com/oral-health/guide/tartar-dental-calculus-overview#1). When tartar buildup it cause discoloration and makes it hard to remove new plaque. It also start attacking and damaging the tooth outer layer which makes it easy for bacteria to penetrate inside the tooth causing tooth decay, cavities and gum disease.
Tooth Decay or cavities
Frequent exposure to plaque and tartar for a long period of time cause damage to the outer teeth surface that develop into tiny holes also called cavities. When the tooth decayed due to frequent exposure to plaque and tartar, it forms a white, brown or black spot to occur inside the tooth (https://www.mayoclinic.org/diseases-conditions/cavities/symptoms-causes/syc-20352892) a sign of serious dental health. Booking an appointment to see your child dentist is the best way to get this sorted out before infection spread out to other nearby teeth.)

Kind of Food and Drinks They Eat /Drink
Frequent eating or drinking of dark food/ drinks such as chocolate, berries, coffee, black tea, red wines, cola, tomato sauce can also cause black stains on children teeth. It is advised that you ask the children to drink plain water immediately after eating or drinking these kinds of foods to avoid stains formation.
Fillings and crowns that contain amalgam, particularly silver sulfide, can cause teeth to appear black in color (https://www.healthline.com/health/black-teeth#causes). This means that incase you see your child has black stains on their teeth while they keep proper dental hygiene but has filling that contain silver amalgam then this can be the cause and nothing to worry about.
In case your kid has a habit of chewing tobacco when it gets mixed with saliva it forms dark brown liquid which is awfully staining. When this liquid left to have contact with the teeth for long time it cause black stains on tooth edges or near the gum line (https://www.smilebrilliant.com/articles/tobacco-stains-on-teeth).
Consuming too much fluoride while the teeth are being formed can lead to fluorosis. This condition causes white or brown discoloration or spots on the enamel, or tooth surface. The spots and stains left by fluorosis are permanent. They may darken over time (https://www.colgate.com/en-us/oral-health/basics/fluoride/fluorosis)
Taking certain medications, such as liquid iron supplements can cause teeth stains (https://www.medicalnewstoday.com/articles/321777.php). If your child’s teeth have dark stains, they could be caused by iron, such as that in a vitamin (http://www.ctkidsdentist.com/blog/causes-stains-childs-teeth/)
