Why Kids Get Yellow Teeth

Posted on January 20th, 2022

New Iberia dentist, Dr. Rebecca Charpentier at Charpentier Family Dentistry discusses reasons that children’s teeth turn yellow and what can be done to prevent or treat the problem.Most adults spend a lot of time, effort and sometimes money to keep their teeth as white as possible. White teeth are considered one of the most important aspects of physical attractiveness in modern culture. If you notice your child’s teeth looking yellow, you may have some cause for concern—but there are plenty of possible reasons for yellow teeth in kids:

  • Dental caries (cavities) and tooth decay
  • Poor oral hygiene that allows plaque formation
  • Excessive fluoride in formula or milk can leave white streaks or patches
  • Hepatitis, jaundice and other ailments can discolor teeth
  • Tooth trauma or injury can break blood vessels, affecting tooth enamel
  • Tetracycline use in pregnant mothers can discolor a baby’s teeth
  • Genetic causes such as missing or thin tooth enamel

The permanent (adult) teeth contain more dentin, which appears yellow in color and is visible below translucent tooth enamel. When sitting beside a baby tooth, the permanent tooth automatically seems more yellow. Once all permanent teeth have erupted, overall tooth color will blend and look more uniform.

Dr. Rebecca Charpentier of Charpentier Family Dentistry does not recommend any type of tooth bleaching or whitening before the age of 12 or 13 years old, when all the permanent teeth are present. If bleached before all the permanent teeth arrive, the ones that arrive later are unlikely to match.
