Why Permanent Teeth Can Look Yellow In Kids
Between the ages of 6 and 7, permanent teeth begin to erupt. Parents may notice that the new teeth look more yellow than the surrounding baby teeth.
This is often completely normal. Permanent teeth contain more dentin than baby teeth. Dentin is the naturally yellowish layer beneath the enamel, so permanent teeth can appear more yellow when they first emerge.
Dentin, Enamel and Tooth Color
Dentin helps protect the inner pulp of the tooth, where the nerves and blood vessels are located. It also plays an important role in tooth colour. Because the enamel of newly erupted permanent teeth can be more translucent, the naturally yellow dentin underneath may show through more clearly. As the enamel matures, the teeth may appear less yellow over time.

Plaque and Tartar Can Make Kids’ Teeth Look Yellow
Plaque buildup can also contribute to yellow teeth in kids. If plaque isn’t removed with regular brushing and flossing, it can collect stains from foods and drinks and eventually harden into tartar, which may appear yellow or brown.
Brushing twice a day for two minutes and regular dental cleanings can help prevent plaque and tartar buildup. If yellow discolouration doesn’t improve with brushing, a dental checkup can help determine whether plaque, tartar or another cause is responsible.
Thin Enamel Can Make Kid’s Teeth Look Yellow
Thin enamel can cause yellow teeth in kids. Enamel is the hard, lighter coloured outer layer of the tooth, while the dentin underneath has a naturally yellow tone. When enamel is thinner than normal, more of the underlying dentin can show through, making the teeth appear yellow. , In some children , thin or weakened enamel may result from problems that occurred while the teeth were developing.

Conditions That Affect Tooth Enamel In Kids
Several conditions can affect the strength, thickness or appearance of a child’s tooth enamel.
Enamel hypoplasia occurs when there is less enamel than normal because the enamel did not fully develop.
Enamel hypomineralization occurs when there is less enamel than normal because developing teeth didn’t absorb essential minerals effectively, The enamel coating remains vulnerable.
Enamel erosion happens when acids gradually wear away the enamel after the teeth have erupted. Frequent exposure to sugary or starchy foods and drinks, poor brushing habits and genetics can contribute to erosion and make the underlying yellow dentin more visible.
When to See a Dentist About Yellow Teeth in Kids
Yellow teeth in kids are often normal, especially when permanent teeth are first coming in. However, it’s a good idea to book a dental appointment if the discolouration is new, getting worse, appears as distinct yellow or brown spots, or doesn’t improve with regular brushing.
Routine dental checkups and cleanings every six months can also help identify plaque buildup, enamel problems or other causes of tooth discolouration early. Children should have their first dental visit within six months of their first tooth appearing or by their first birthday.
