Causes of Teeth Discoloration in Babies and Children and Recommendations for Treatment

In this article, we will tell you the causes and treatment methods of teeth discoloration in babies and children.

From time to time, families may complain that their babies or children have tooth discoloration. Iron preparations started between 4 months and 6 months at the beginning of the causes of tooth discoloration. In addition, frequent use of antibiotics can cause discoloration of the teeth.

But there are many other reasons that we overlook. We will also talk about them in this article. First of all, we should point out that the teeth of an adult individual are not that white. His teeth have some yellowing. But you will notice that children’s milk teeth are whiter than the teeth of adults. This is because milk teeth contain more calcium. Despite this situation, there is a situation that can be contradictory. Because although the teeth of babies or children are not very rotten, they can change color very easily. The most common reason here is the misconceptions or incomplete knowledge about tooth brushing.

When should children start brushing their teeth?

We perceive brushing as something that should be started after tooth eruption, but this is wrong. Because tooth brushing is a situation that should be started as soon as you start solid food for your baby and in the same way, if your baby has started teething at 4 months and 5 months, even if you have not started solid food, you should brush your teeth.

In other words, if your baby’s teeth have come out or you have started solid food, you need to start brushing teeth, we recommend using a toothpaste with organic content for this. The American Society of Pediatrics says you can use a toothpaste with fluoride.

What happens if you don’t brush your children’s teeth?


Plaques form in the mouth due to the organics created by the bacteria in the mouth and some decay. However, the majority of these formations, unfortunately, do not go away despite tooth brushing. This condition can only return to normal after children’s teeth fall out.

Tooth discoloration due to iron preparations

The second possibility is the most well-known. Iron preparations that are started between the 4th and 6th months in babies and the active ingredients in some antibiotics can cause color changes in the teeth. The most common of these active substances are tetracyclines.

Tooth discoloration due to drugs used during pregnancy and breastfeeding

Color changes have been detected in the teeth or bones of babies due to the use of antibiotics and tetracycline-containing drugs and iron preparations during pregnancy and breastfeeding periods. Therefore, do not forget that the drugs and antibiotics used by mothers during both pregnancy and breastfeeding should be chosen very carefully.

Darkening of the tooth due to a blow to the tooth

If your baby or child’s teeth do not have a serious discoloration, but only one of them has such a serious darkening. The reason for this is usually because one of the blood vessels feeding the tooth in the child’s tooth bleeds due to trauma, that is, due to the impact, and stains the inner structures a little. There is no cure for this condition.

Tooth discoloration due to genetic factors

Another reason is that some families genetically have that layer called enamel on the top of the teeth that is weaker and can darken more easily. This can cause discoloration of milk teeth. There isn’t much you can do here. You should show maximum care as much as possible and you should pay attention to prevent this situation from increasing.

Tooth discoloration due to excessive fluoride intake


Another cause of tooth discoloration is excessive fluoride intake, especially if there are white lines on the teeth. If your baby is using formula and you do this with a fluoride-enriched liquid, then your child may have a discoloration in the form of white stripes on their teeth. If you have such a thing, you can go to your pediatrician and make sure that research is done on this issue and that your medications or treatments are rearranged if necessary.

Tooth discoloration due to jaundice

In some cases, newborn babies may encounter a problem known as “newborn jaundice”. What is known as neonatal jaundice, or hyperbilirubinemia, can cause a slight greenish staining of yellow in babies’ skin. The discoloration and staining here can also cause staining in different tissues in the body, brain tissue, normal muscle tissue, and bone tissue. It can also cause discoloration of the teeth. In other words, if your baby has had an excessive amount of jaundice during the newborn period, it is quite normal for your baby’s teeth to teeth with a slightly yellow and green color and for milk teeth to be colored like this. There is not much you can do for it, but we can say that it is not harmful.

Conclusion and recommendations

As much as possible, try not to make your babies and children use antibiotics too often. Because the need for antibiotics in the childhood age group is really very low. Apart from this, if you are pregnant or breastfeeding, the type of antibiotics you will use is very important. If the antibiotic you are going to use is really necessary, you will have to use it. You have no choice. However, you should not forget that some antibiotics that you will use can easily cause tooth discoloration after your child is born or during breastfeeding.

If poor dental hygiene causes tooth discoloration, then you can try to increase tooth brushing a little more, to do it a little more carefully. You can make your child perceive the habit of brushing teeth as a game. In this way, your child will start brushing with you. You don’t have to use toothpaste as you can’t teach your child to spit easily before they are 3 years old. Tooth brushing is the brushing itself that matters, not toothpaste. But if you want to use toothpaste, in this case, be careful to use a toothpaste that contains either organic ingredients or fluoride, as recommended by the American Pediatric Dentists Association. Also remember that the amount of toothpaste should be less than a grain of rice.

Try not to give fruit juices or sugary drinks with a bottle to reduce cavities or the formation of dental plaque, and to prevent bacteria on the teeth from creating more cavities. Also, don’t try to sweeten the pacifiers in any way.

 Another recommendation is that feeding the child while they sleep is not very correct in terms of children’s dental health. We recommend that children brush their teeth before bedtime, if possible.

Do not share containers of your own food with your babies or children. If you share something you ate from your lunch box to your child, then it will be easier for bacteria to reach him in your mouth and increase the likelihood of cavities.

Finally, do not forget to take your children to the pediatric dentist regularly.
