Baby Teeth Basics
Baby teeth are the first teeth that grow in your mouth. They are also called primary teeth. You get 20 baby teeth in all. This is less than the 32 adult teeth you will have later.
What Are Baby Teeth?
Baby teeth are small. They are white. They help you:
- Chew food
- Talk and make sounds
- Smile and look nice
Baby teeth save space for your adult teeth. They help your face grow the right way too.
Why Baby Teeth Matter
Baby teeth are not just for show. They help with:
- How you talk
- What you can eat
- How your jaw grows
- Making room for adult teeth
If baby teeth get hurt or come out too soon, it can cause big problems later. Your face and mouth might not grow right.
Baby Teeth Timeline
Baby teeth start to come in when babies are about 6 months old. Most kids have all their baby teeth by age 3.
Eruption Chart
Here is when baby teeth come in:
Tooth Type | When It Comes In |
---|---|
Bottom front teeth | 6-10 months |
Top front teeth | 8-12 months |
Side front teeth | 9-13 months |
First molars | 13-19 months |
Canine (pointy) teeth | 16-22 months |
Second molars | 23-33 months |
It’s OK if teeth come in a bit early or late. All kids are different!
When to Worry
Most of the time, you don’t need to worry. But call the dentist if:
- No teeth by 18 months
- Teeth grow in very crooked
- Some teeth are missing
- Teeth have spots or marks
When baby teeth grow in the wrong way, it might mean there is a problem.
Teething: Symptoms & Soothing
When baby teeth push through gums, it can hurt. This is called teething.
Signs of Teething
Look for these signs:
- Lots of drool
- Red or puffy gums
- Want to chew on things
- Fussy or cranky
- Not sleeping well
Note: Teething does NOT cause fever or diarrhea. If your baby has these, call the doctor.
Safe Remedies
Here’s what helps:
- Cold (not frozen) teething rings
- Clean finger to rub gums
- Cool washcloth to chew on
Don’t use numbing gels with benzocaine. They can be unsafe for babies.

Caring for Baby Teeth
Taking care of baby teeth is very important!
Brushing & Flossing
Start cleaning teeth as soon as they come in:
- Use a tiny bit of toothpaste (size of a rice grain)
- Brush two times every day
- Use a soft toothbrush made for babies
- Start flossing when teeth touch each other
Use fluoride toothpaste to make teeth strong. It helps stop cavities.
Avoiding Decay
Baby teeth can get holes called cavities. To avoid this:
- No bottles at bedtime
- Limit juice and soda
- No all-day sippy cups with sweet drinks
- Clean teeth after eating
Did you know? About 23% of kids ages 2-5 have cavities. That’s almost 1 in 4 kids!
Common Problems & Solutions
Baby teeth can have problems. Here are some common ones.
Tooth Decay
Decay means holes in teeth. It happens when:
- Sugar sits on teeth too long
- Teeth are not cleaned well
- Babies drink sweet drinks in bed
For small cavities, the dentist might use silver diamine fluoride. It’s a special liquid that stops decay. For bigger cavities, they might need to put a crown on the tooth.
Grinding (Bruxism)
Many kids grind their teeth at night. This is called bruxism.
Good news! Most kids stop grinding as they grow. If it’s very bad, the dentist might make a night guard to protect the teeth.
Trauma
If a baby tooth gets knocked out or chipped:
- Stay calm
- Find the tooth or piece
- Call the dentist right away
- Don’t try to put a baby tooth back in
Trauma to baby teeth can hurt adult teeth growing under them.
Losing Baby Teeth
Losing baby teeth is normal and exciting!
When Do They Fall Out?
Baby teeth start to fall out around age 6-7. The last ones usually fall out by age 12.
Here’s the order:
- Bottom front teeth (age 6-7)
- Top front teeth (age 6-8)
- Side front teeth (age 7-8)
- First molars (age 9-11)
- Canines (age 9-12)
- Second molars (age 10-12)
Complications
Sometimes things don’t go as planned:
- Shark teeth: Adult teeth come in behind baby teeth
- Early loss: Baby teeth fall out too soon
- Late loss: Baby teeth stay too long
If baby teeth fall out too early, the dentist might put in a space maintainer. This keeps room for adult teeth.
Dental Visits
First Visit Timing
Take your child to the dentist by age 1 or when the first tooth comes in. Don’t wait!
The first visit is usually:
- Short and fun
- A chance to check teeth
- Time to learn how to care for teeth
- A way to get kids used to the dentist
Common Procedures
At dental visits, the dentist might:
- Count teeth
- Clean teeth
- Put on fluoride varnish to stop cavities
- Take X-rays (for older kids)
- Put on sealants to protect teeth
Sealants are like rain coats for teeth. They keep food and germs out of the grooves.
