Many Glen Iris parents are surprised to discover that stained or yellowing teeth don’t just happen to adults — they can appear in young children and even babies. Understanding why this happens can help you protect your child’s developing smile.
Normal Baby Tooth Colour
Baby (primary) teeth are typically a soft off-white or ivory shade, and slight colour variations are normal. However, noticeable yellowing or discoloration is often caused by inadequate brushing or early tooth decay.
Just like adults, children need their teeth brushed twice a day, including after meals when possible. Without good brushing habits, plaque and cavity-causing bacteria can quickly build up.
White Spots or Streaks? It May Be Fluorosis
If you notice faint white streaks or chalky spots on your child’s teeth, this may be fluorosis — a harmless cosmetic condition caused by too much fluoride exposure early in life.
How to Prevent Fluorosis
-
Use only a rice-grain–sized amount of fluoride toothpaste for children under 3
-
Ensure children don’t swallow toothpaste
-
Be aware that most Melbourne water supplies, including Glen Iris, already contain fluoride
Fluoride is essential for keeping children’s teeth cavity-free by promoting re-mineralisation, so don’t cut it out entirely. If you’re unsure how much fluoride your child needs, speak to Dr Kaufman at Tooronga Family Dentistry.
Illness, Infection, and Medications
Several medical factors can influence tooth colour during early childhood development:
-
Jaundice after birth can cause a greenish tint to teeth
-
Infant infections may lead to darker discolouration
-
Medications, such as iron supplements or certain antibiotics, may cause visible staining
If you notice unusual colours — brown, grey, green, or dark spots — it’s worth having your child examined.
When Should Babies See a Dentist?
Babies should have their first dental visit before their 1st birthday, or within 6 months of the first tooth erupting. Early visits help establish healthy habits, detect problems sooner, and give parents confidence about caring for their child’s smile.
