My Child's Teeth Are Discolored!

Dark teeth can appear in permanent or primary teeth. Discoloration, particularly in the front teeth, can cause aesthetic concerns in both parents and children. Due to the increasing visual perception of children and adolescents today, it can sometimes negatively impact their psychological well-being, leading to a lack of self-confidence and social isolation.

Dark teeth can appear brown-black, yellow-orange, or green-gray. These discolorations, which can sometimes be mistaken for cavities, should be discussed with a pediatric dentist as soon as possible to determine the cause, treat them, and take the necessary precautions.

What Causes Tooth Discoloration?

While discoloration can have many causes, the most common are poor oral hygiene, the use of iron medications, and the growth of certain color-causing bacteria in the mouth.

What Causes Black and Brown Discolorations?

These are the most common discolorations in children. Studies conducted in children aged 5 to 13 in our country have calculated the prevalence of this type of discoloration to be approximately 17%. This means it affects approximately one in every five school-aged children. It generally appears in areas close to the gums, parallel to the gums, in spots or bands. It is most common on the upper front teeth, which are unable to benefit from the rinsing effect of saliva. It is caused by an increase in color-producing bacteria in the mouth. These bacteria are called chromogenic bacteria. This type of discoloration occurs when the chemicals produced by chromogenic bacteria combine with the iron in saliva or gingival fluid. Therefore, the use of iron-containing medications increases the likelihood of discoloration.

What Causes Gray-Green Discoloration?

This type of tooth discoloration, which can appear gray, brown, or green, is usually seen in the upper front primary teeth. This type of discoloration, which is twice as common in boys as in girls, is caused by tissue residue left on the tooth surfaces during the eruption of primary teeth. This type of discoloration occurs when the structure surrounding the tooth surfaces, called the Nasmyth membrane, breaks down over time and does not completely remove itself from the tooth surface, resulting in the growth of chromogenic bacteria in the area.

What Causes Yellow-Orange Discoloration?

This type of discoloration is seen in areas near the gums in cases of inadequate oral hygiene. It is more common in the upper or lower front teeth. This type of discoloration is often observed in children with malnutrition.

How Are Tooth Discolorations Treated?

Once the cause and type of external discoloration are identified, treatment can be initiated. Discoloration can usually be removed with a thorough cleaning (polishing) with fluoride-containing paste. In some cases, ultrasonic cleaning devices may also be used. However, for the treatment to be effective, daily oral care must be followed closely. Your dentist will provide detailed recommendations for eliminating the factors causing the discoloration.

How Can I Take Precautions?

1. First and foremost, the child's oral hygiene should be maintained to the highest standard. At checkups, detailed information on oral care, depending on their age, will be provided. To prevent bacterial transmission from parents or siblings, avoid sharing food and drink, and pay attention to the hygiene of pacifiers and baby bottles.
2. Habits such as kissing the child on the lips can also spread these discoloring bacteria.
3. To prevent recurrence of discoloration caused by iron supplements, immediately after administering the medication, the child should be given water or rinsed with a mouthwash, and then brushed.
4. You can consult your dentist to discuss the possibility of changing the medication.

Discoloration or Decay?

These two conditions can often be confused, especially with black discoloration. If sensitivity or pain is present, you should consult a pediatric dentist as soon as possible. Treatment for decay may be necessary.

So, What Should Be Done for Internal Tooth Discoloration?

Besides the external discoloration mentioned above, we can sometimes observe different discolorations within the tooth. These discolorations may develop due to the medication used (especially tetracycline), high fluoride intake, genetic disorders, or other causes. A detailed examination is necessary for diagnosis and treatment.
