On day five, my daughter's mouth had white patches that
wouldn't wipe away. Thrush. The pediatrician prescribed antifungal drops and
taught me to clean her gums after each feeding with a soft cloth. "Start
oral care now," she said, "months before teeth appear." I had no
idea. Here's why newborn dental care begins at birth, not when the first
teeth erupt.
Why Oral Care Starts at Birth
Building Healthy Habits Early
Newborn dental care
establishes oral hygiene as a normal part of daily routine.
When you start early, the baby gets used to mouth care.
By the time teeth arrive, the routine is already familiar.
It's easier to maintain a habit than create a new one
later.
Preventing Bacteria Buildup
Milk residue and bacteria accumulate on gums even
without teeth.
This buildup can lead to problems when teeth do erupt.
Clean gums = healthier environment for incoming teeth.
Preparing for First Teeth
Healthy gums support healthy teeth.
Regular gum cleaning prepares the mouth for teeth. The
gums stay strong and are less prone to inflammation.
Oral Thrush Prevention
Oral thrush (candida overgrowth) appears as white
patches in the baby's mouth.
Regular gum cleaning helps prevent thrush by removing
milk residue where yeast can grow.
My daughter got thrush despite cleaning. Without
cleaning, it would have been worse or happened repeatedly.
Cleaning Baby's Gums
Start from Day One
You can start cleaning gums from birth.
Incorporate gum cleaning into your daily hygiene
routine along with bathing. We started at the hospital after the
pediatrician showed us how.
Early start = early habit formation.
Using a soft, Damp Washcloth
What you need
- Clean, soft washcloth or gauze
- Plain water (no soap, no toothpaste)
- Clean hands
How to do it
1.
Wrap a damp
cloth around your finger
2.
Gently
wipe gums and inside of cheeks
3.
Use
gentle, circular motions
4.
Cover
all gum surfaces
It takes 30 seconds max.
Gentle Wiping After Feeds
Ideal time: After feeding, when milk residue is fresh.
Reality: This is hard to maintain with every single
feeding. Once or twice daily is fine.
We aimed for after morning feed and before bed.
Once or Twice Daily Is Enough
Don't stress about cleaning after every feeding.
Realistic routine:
- Morning: After first feed
- Evening: Before bedtime
This frequency prevents buildup without becoming
burdensome.
What NOT to Use
Avoid
- Regular toothpaste (before first tooth)
- Mouthwash
- Harsh scrubbing
- Rough clothes
- Antibacterial products
Plain water and gentle wiping is all you need for gums.
When First Teeth Appear
Average Timeline (4-7 Months)
Most babies get their first tooth between 4 and 7
months, with an average of around 6 months.
My daughter got her first tooth at 5 months. My son is
7 months.
Both completely normal.
Wide Range of Normal
Normal tooth eruption range: 3-12 months
Some babies get teeth at 3 months. Others don't see
teeth until their first birthday.
Both ends of this spectrum are normal. Don't compare it
to other babies.
Bottom Front Teeth Usually First
Typical eruption order
1.
Bottom
two front teeth (lower central incisors)
2.
Top two
front teeth (upper central incisors)
3.
Top
lateral incisors (next to front teeth)
4.
Bottom
lateral incisors
5.
First
molars
6.
Canines
(pointed teeth)
7.
Second
molars
By the time they turn three, children usually have their full set
of 20 baby teeth
Natal Teeth (Rare)
About 1 in 2,000-3,000 babies are born with teeth
already present (natal teeth).
These are usually loose and may need removal if they
pose a choking hazard or interfere with feeding.
If your baby is born with teeth, the dentist will
evaluate.
Tooth Eruption Order
|
Teeth |
Typical Age |
Number |
|
Lower central incisors |
6–10 months |
2 teeth |
|
Upper central incisors |
8–12 months |
2 teeth |
|
Upper lateral incisors |
9–13 months |
2 teeth |
|
Lower lateral incisors |
10–16 months |
2 teeth |
|
First molars |
13–19 months |
4 teeth |
|
Canines |
16–23 months |
4 teeth |
|
Second molars |
25–33 months |
4 teeth |
This is a guideline. Your baby's timeline may differ.
Signs Your Baby Is Teething
Drooling
Increased drooling is a classic teething sign. Baby suddenly soaking through bibs. Shirts are constantly wet. Drool rash on the chin. Starts weeks before the tooth breaks through.
Hand-to-Mouth
Baby constantly chewing on fists, fingers,
toys—anything they can reach.
They're trying to relieve gum pressure. The pressure
feels better with counter-pressure.
Gum Rubbing
Baby rubs gums together or rubs the area with fingers.
If you feel their gums, you might notice hard spots
where teeth are pushing through.
Irritability
Some babies get fussy during teething. More crying,
harder to soothe.
Not all babies show this. My daughter was cranky. My
son barely noticed.
What Teething Doesn't Cause (Fever, Diarrhea)
Important - Teething does NOT cause
- Fever over 100°F
- Diarrhea
- Vomiting
- Severe diaper rash
- Loss of appetite
Teething might cause slight temperature elevation
(under 100°F) and loose stools, but true fever or diarrhea indicates illness,
not teething.
If the baby has a fever, look for other causes. Don't
blame teething.
Teething Relief
Cold Teething Toys
Cold numbs gums temporarily.
What works
- Refrigerated (not frozen) teething rings
- Cold washcloth to chew
- Refrigerated pacifiers
Don't freeze solid - Too
hard can damage gums.
Gentle Gum Massage
Rub baby's gums with a clean finger using gentle
pressure.
Many babies find this soothing. Some hate it.
Try it. Baby will tell you if it helps.
What to Avoid (Teething Tablets, Gels with Benzocaine)
FDA warns against -
- Benzocaine gels (Orajel, Anbesol):
Can cause a serious blood condition (methemoglobinemia)
- Homeopathic teething tablets:
Some contained belladonna (toxic)
- Amber teething necklaces:
Choking and strangulation hazard
Don't use these products. They're not safe.
When to Use a Pain Reliever
If the baby is truly miserable, acetaminophen or
ibuprofen can help.
Guidelines
- Acetaminophen: Safe from birth (dose by weight)
- Ibuprofen: Only for those over 6 months old
Ask the pediatrician about dosing. Use sparingly, not
daily for weeks.
First Tooth Care
Brushing with an Infant Toothbrush
Start brushing as soon as the first tooth appears.
Infant toothbrush features -
- Very soft bristles
- Small head
- Easy-grip handle
- Designed for tiny mouths
We used a finger brush at first (a rubber brush that
fits on a finger). Easier control.
Fluoride Toothpaste (Rice-Grain Amount)
AAP and AAPD now recommend fluoride toothpaste from the
first tooth.
Use rice-grain-sized smear (not pea-sized—that's for
age 3+).
Fluoride strengthens enamel and prevents cavities. The
tiny amount is safe if swallowed.
Twice Daily Routine
Brush baby's teeth twice daily:
- Morning (after breakfast)
- Evening (before bed)
Evening brushing is most important, as it removes the day's
buildup before a long sleep.
Making It Fun
Tips for cooperative brushing
- Let the baby hold their own brush while you use another
- Sing brushing song
- Making silly faces
- Brush your teeth together (they copy you)
- Use flavoured toothpaste (if baby likes it)
Some resistance is normal. Keep it quick and
consistent.
H2: Pacifiers and Thumb Sucking
Effects on Oral Development
Thumb sucking and pacifier use are common ways children soothe
themselves
Potential issues (only with prolonged use past age 3-4)
- Changed tooth alignment
- Narrowed palate
- Bite problems
Before age 2 - harmless.
When It's Okay
Pacifier use in the first year is fine and even beneficial
- Reduces SIDS risk
- Provides comfort
- Easier to wean than thumb (can take away pacifier, can't remove
thumb)
Thumb sucking under age 2 is also normal and harmless.
When to Wean
Recommended weaning timeline
- Pacifier - Between ages 2-3
- Thumb sucking - By age 4
Most kids naturally reduce these behaviours as they get
older.
If still at age 4+, the dentist may recommend
intervention.
First Dental Visit
By Age One or First Tooth
AAPD recommendation - First
dental visit by age one or within 6 months of first tooth eruption, whichever
comes first.
Example: Tooth appears at 6 months → schedule visit by
12 months.
Early dental checkups create a lasting care base and help detect
issues sooner.
What to Expect
First visit typically includes
- Teeth and gums
- Assessment of bite and jaw development
- Check for oral issues (thrush, tongue tie)
- Oral hygiene education for parents
- Fluoride application (sometimes)
- Discussion of diet and oral habits
Usually quick (15-20 minutes). The goal is familiarity,
not treatment.
Finding a Pediatric Dentist
Look for
- Pediatric dentistry specialty
- Child-friendly office
- Accepts your insurance
- Convenient location
Children’s dentists receive specialized training in growth patterns
and managing young patients’ behaviour.
Common Oral Issues in Newborns
Oral Thrush
What it is: Yeast infection in the mouth
(candida).
Signs
- White patches on the tongue, gums, and inside cheeks
- Patches don't wipe away easily
- The baby may refuse to feed or seem uncomfortable
Treatment - Antifungal drops prescribed by the doctor.
Treat for the full course (usually 10-14 days).
Know when to call about oral issues like thrush
or feeding difficulties. My daughter needed treatment at 5 days old.
Prevention - Clean gums regularly, sterilize
pacifiers/bottle nipples, and treat maternal yeast infections.
Tongue Tie (Ankyloglossia)
Tongue tie occurs when the tissue under the tongue (frenulum)
is too short or tight.
Effects
- Difficulty latching for breastfeeding
- Poor milk transfer
- Clicking sounds while feeding
- Speech problems (later)
Learn how tongue tie and feeding difficulties
are connected. Some babies need frenectomy (a simple procedure to release the tie).
Not all tongue ties require treatment—only those
causing problems.
Lip Tie
Similar to tongue tie, but affects upper lip attachment.
Can interfere with feeding and create a gap between the front
teeth.
Assess if causing feeding problems. Many resolve on
their own.
Natal Teeth
Around 1 in every 2,000–3,000 newborns are born with teeth already
present.
Usually harmless if
- Firmly attached
- Not interfering with feeding
- Not causing injury to the baby or the mother
Loose natal teeth may need removal to prevent choking. The
dentist will evaluate.
My Experience with Newborn Dental Care
Week 1 - Thrush diagnosis. Started cleaning
gums after every feeding with a damp cloth.
Month 2 - Reduced to twice-daily gum cleaning.
Much more sustainable.
Month 5 (daughter) - First
tooth! I started brushing with a finger brush and rice-grain fluoride paste.
Month 7 (son) - First tooth appeared. By then,
brushing felt routine from experience with my daughter.
At 12 months, children should have their first dental appointment. Quick
exams. Both have fluoride applications.
What I learned
- Gum cleaning is easier than I expected
- Starting early made tooth brushing less of a battle
- Teething symptoms vary wildly between kids
- Dentist visits aren't scary for babies who don't know how to be
scared
- Consistency matters more than perfection
The twice-daily gum cleaning took 30 seconds each time.
When teeth came, we just swapped a cloth for a toothbrush. Easy transition.
Conclusion
Newborn dental care starts
from birth with simple gum cleaning.
Use a soft, damp cloth once or twice daily. When the first
tooth appears (usually for 4-7 months), start brushing with a rice-grain amount
of fluoride toothpaste.
Key takeaways
- Clean gums from day one
- First tooth = start brushing
- Use fluoride toothpaste (tiny amount)
- Teething is uncomfortable, not dangerous
- First dental visit by age one
- Pacifiers are fine in the first years
- Watch for thrush and tongue tie
Oral habits start early. The effort you put into it
now prevents problems later.

Frequently Asked Questions
Q: Do I really need to clean my baby's gums before
teeth come in?
A: Yes. Cleaning removes bacteria and milk residue,
prevents thrush, and establishes an oral care routine. Use a soft, damp washcloth
once or twice daily.
Q: At what age do first teeth usually appear?
A: Average is 6 months, but 3-12 months is the normal
range. Some babies are born with teeth (natal teeth); others don't get teeth
until after their first birthday.
Q: Should I use fluoride toothpaste on my baby?
A: Yes, AAP and AAPD now recommend fluoride toothpaste
from the first tooth. Use a rice-grain-sized amount. Fluoride strengthens enamel and
prevents cavities.
Q: Can teething cause a fever?
A: No. Teething may cause slight temperature elevation
(under 100°F), but it doesn't cause true fever. If the baby has a fever, look for other
causes like illness.
Q: When should my baby see a dentist?
A: By age one or within 6 months of the first tooth,
whichever comes first. Early visits establish dental homes and prevent
problems.
