The falling of milk teeth and the arrival of permanent teeth is a natural developmental process in children. Generally, milk teeth begin to fall at around 6–7 years of age and are fully replaced by permanent teeth by 12–13 years. However, in some children, this process gets delayed — leading to confusion and concern among parents.

What Causes Delay in Milk Teeth Falling?

According to Dr. Rakesh Bagdi, former pediatric specialist at AIIMS, Delhi, the reasons behind this delay can vary from nutritional issues to natural growth patterns.

1. Nutritional Deficiencies

• Lack of calcium, vitamin D, and essential nutrients may delay tooth development and make the root resorption of milk teeth slower.

• Calcium and vitamin D are critical for strong teeth and jawbone structure.

2. Slow Growth of Permanent Teeth

• Sometimes, the permanent teeth do not erupt on time due to delayed development inside the jaw.

• When the permanent tooth does not push against the root of the milk tooth, the old tooth does not loosen or fall.

3. Heredity and Natural Variation

• Every child’s growth timeline is unique.

• If a parent or sibling also lost teeth late, this delay could be hereditary and normal.

4. Strong Roots of Milk Teeth

• Occasionally, the roots of milk teeth remain intact longer than expected.

• This prevents the teeth from loosening and can cause misalignment when the permanent teeth arrive.

When Should You See a Doctor?

While a slight delay is common, consult a pediatric dentist if:

• No milk teeth fall by age 7–8

• By age 9–10, several milk teeth are still intact

• Permanent teeth are emerging, but the milk teeth have not fallen

• The child is facing eating or speaking difficulties

• There are signs of pain, swelling, or infection

Risks of Delayed Tooth Loss

• Crooked Teeth: Permanent teeth may erupt at the wrong angle.

• Overcrowding: Two teeth may occupy the same space, making brushing harder and increasing the risk of cavities.

• Gum Infections: Delayed shedding may lead to irritation or gum swelling.

Dental Care Tips for Children

Dr. Bagdi recommends the following for healthy teeth:

✅ Healthy Habits

• Brush twice daily using child-friendly toothpaste.

• Rinse the mouth after meals, especially sweets.

✅ Diet Tips

• Avoid excessive sugar, soft drinks, and sticky snacks.

• Include calcium-rich foods (milk, paneer, yogurt), vitamin D (sunlight, fortified cereals), and protein (eggs, pulses).

✅ Dental Check-Ups

• Visit a dentist every 6 months.

• Seek early treatment if milk teeth aren’t falling or permanent teeth seem misaligned.

After Tooth Falls – What to Do?

• Keep the area clean and encourage rinsing with lukewarm salt water if there’s bleeding.

• Ensure the child doesn’t poke or irritate the area with fingers or tongue.
