We all want our child’s smile to be the brightest and healthiest that it can be. When we notice that their teeth are discolored, it is natural to be concerned and ask yourself, “Why are my child’s teeth yellow?” The yellowing may be internal or external, and there are many things that can cause this discoloration. Speaking with your child’s dentist is always recommended before making any attempts to whiten the teeth, and the Gator Crew at Alligator Dental is always here to help. Check out five common causes of yellow teeth in children and then give us a call to speak with a dentist in Seguin today!

Common Causes of Yellow Teeth


Prescription medications can often have several undesirable side effects. Tetracycline is an antibiotic that is used to treat a wide variety of bacterial infections, and it is often prescribed for acne. It destroys certain types of cells in the body, and this can cause yellow streaks on teeth. Doctors often avoid prescribing this antibiotic to children when possible.

Food and Drink

We know that certain beverages can discolor teeth, and children’s teeth are just as susceptible to staining. Just as dark tea and coffee can discolor permanent teeth over time, soda and fruit juices can cause stains on children’s teeth. Even soy sauce can cause discoloration if consumed often enough. Rinsing with water after consuming these foods can help reduce staining.

Too Much Fluoride

A condition called fluorosis can develop if your child ingests too much fluoride while their teeth are developing under the gums. Fluoride may come from toothpaste and other dental care products, water sources, and supplements. Teeth affected by fluorosis may have surface irregularities and staining, ranging from white lacy marks to yellow and brown discoloration.

Poor Oral Hygiene

Teaching your child good brushing and flossing habits is important not only for a healthy smile, but also for encouraging a white smile. Poor brushing and flossing habits can allow plaque to build up on teeth, and if this happens, you may begin to notice that your child’s teeth have a yellow tinge to them. This demonstrates the importance of good oral hygiene practices.


If you notice that one or more of your child’s teeth has suddenly become more yellow than the others, this could be a sign that it has suffered some kind of trauma. You can help protect your child’s teeth by encouraging the use of mouthguards and other protective equipment. It is important to contact the dentist if you suspect your child has suffered some type of oral injury.
