The Culprits behind Your Child’s Discoloured Teeth

Kid's Dental HealthInfants and children are just starting to grow their teeth, so it may be a cause of concern to see some discolouration. The teeth are still young and new, so why would your child have yellowed or stained teeth?

In Derby, many dentists limit cosmetic dentistry to adults. The recommended age for getting your first tooth whitening procedure is at 18 years old. Understandably, some parents find it upsetting, especially if they feel that their child needs it. But what are the causes behind staining?

Here are just some of the reasons your child's teeth have stains:

Poor Oral Hygiene

Poor oral hygiene and the excessive consumption of sugar are two of the most common causes of stained teeth. Young children need to be closely supervised while they are brushing their teeth, as they have not yet developed the skills necessary to brush properly. If needed, help them with brushing to make sure that you clear teeth of debris and plaque build-up.


Some infant medications may cause staining and discolouration. Iron and other vitamins and minerals are common culprits, as these materials may change the colouration of the enamel. Pregnant women who took the antibiotic tetracycline may also find that their child's first teeth are discoloured once they emerge.


Fluoride is good for the teeth, but in some cases it causes stains. If your child is exposed to too much fluoride, small white spots or streaks may appear on their teeth. This is not dangerous, however, as it is entirely cosmetic.

Newborn Jaundice

Newborn jaundice is common, especially among breastfed babies. The skin and the eyes of the newborn may look yellowish in appearance, while the teeth may take on a greenish tint. Infant jaundice usually goes away on its own, so it is usually not a cause for concern.

When it comes to the staining of primary teeth, prevention is still better than cure. Care for your child’s teeth before these become discoloured. Of course, some of the culprits behind stained teeth are out of your jurisdiction, but in most cases, it is entirely preventable.
