Every day in the clinic, parents tell me a few things about milk teeth. They come from a good place: milk teeth are temporary, and nobody wants to put a young child through treatment they don’t need. But each of these beliefs can lead to a small problem quietly becoming a big one.

Here are the four I hear most often, and what I tell parents in return.

1. “Doctor, doodh ke daant hain, gir jayenge.” (They’re milk teeth, they’ll fall anyway.)
Yes, they will. But not as soon as most parents think. The front milk teeth usually fall between 6 and 8 years of age, while the back milk molars often stay until 10 to 12 years. A cavity in a 4-year-old’s back tooth could be in the mouth for another seven or eight years.

That’s a long time to live with a cavity. Decay in milk teeth spreads quickly because their enamel is thinner than in adult teeth. Over time it can lead to pain, infection, difficulty chewing, poor sleep and missed school days.

2. “Dard toh nahi ho raha usko.” (But he’s not in pain.)
Cavities in milk teeth often don’t hurt until they are quite deep, sometimes close to the nerve. Many children also don’t say “my tooth hurts”. Instead, they chew on one side, avoid certain foods, or become cranky at night.

No pain doesn’t mean no problem. Treating a cavity early, before it hurts, is usually quicker, simpler and much more comfortable for your child.

3. “Permanent teeth aayenge, tab dekh lenge.” (We’ll see when the permanent teeth come.)
The permanent tooth develops right underneath the milk tooth, very close to its roots. If a milk tooth becomes infected, the infection can affect the permanent tooth even before it comes out. This can show up later as white or brown spots, weak enamel, or a permanent tooth that comes in out of position.

Looking after milk teeth is one of the best ways to protect the adult teeth that follow.

4. “Nikaal hi do, doctor.” (Just pull it out, doctor.)
Milk teeth do more than help children chew. They hold space for the permanent teeth. If a milk tooth is removed too early, the neighbouring teeth can drift into the gap, and the permanent tooth may not have enough room to come in. This can lead to crowded or crooked teeth, and sometimes braces later on.

Whenever we can, we save the milk tooth. If a tooth really does need to be removed early, we often place a space maintainer, a small appliance that holds the gap open until the permanent tooth arrives.

Why milk teeth matter

• Chewing and nutrition: children need healthy teeth to eat a full, balanced diet.

• Speech: milk teeth help children form sounds and words clearly.

• Space for adult teeth: they guide the permanent teeth into the right position.

• Confidence: a healthy smile matters to children too.

• Comfort: no child should have to live with toothache or infection.

What parents can do

• Brush twice a day with fluoride toothpaste: a rice-grain-sized smear under 3 years, a pea-sized amount from 3 to 6 years.

• Limit sugary snacks and drinks, and avoid milk or juice after the night brush.

• Watch for early signs: white or brown spots, food getting stuck, chewing on one side, or a small pimple-like bump on the gums.

• Visit a pediatric dentist by your child’s first birthday, and then every six months.

So yes, milk teeth will fall one day. But until then, they need care, just like adult teeth.

FAQs

Is it worth filling a cavity in a milk tooth that will fall out anyway?
Usually, yes. Many milk teeth stay in the mouth for years. Treating a cavity early prevents pain and infection and protects the permanent tooth developing underneath. Your pediatric dentist will advise based on the tooth and how long it is likely to stay.

At what age do milk teeth fall out?
The front teeth usually start falling around 6 years of age. The back milk molars typically fall between 10 and 12 years.

Can a decayed milk tooth really affect the permanent tooth?
Yes. An infection in a milk tooth can affect the developing permanent tooth underneath, causing spots, weak enamel or changes in how it comes in.

My child’s milk tooth has a small black spot but no pain. Should we wait?
It’s best to get it checked. Small cavities can be treated quickly and simply. Waiting often means the cavity grows and needs more treatment.

What is a space maintainer?
A small, custom-made appliance that holds the space of a milk tooth lost too early, so the permanent tooth has room to come in properly.

How can I prevent cavities in milk teeth?
Brush twice a day with the right amount of fluoride toothpaste, limit sugary foods and drinks, avoid bottles at bedtime, and visit a pediatric dentist regularly.
