Eight tools and answers, no appointment needed

Everything we wish parents knew sooner

Start with what your child's mouth needs at their age, tap through the baby tooth chart, get the brushing and flossing routine right, then read the straight answers on habits, snacks, braces and mouthguards.

What a mouth needs, age by age

We are a pediatric practice, so the five child stages below are where our detail lives. The last two exist because parents ask us constantly what happens when a child outgrows us, and what they should be doing about their own teeth.

  1. 0 to 3Our patients

    First tooth, first visit

    The lower central incisors usually arrive between six and ten months, and all twenty primary teeth are typically in by age three.

    At the practice

    • Knee-to-knee exam on your lap, about half an hour
    • Lift-the-lip check of the upper front gumline, where early childhood caries starts
    • Fluoride varnish painted on in seconds
    • A real conversation about bottles, night feeds and teething

    At home

    • Wipe the gums after feeds before any teeth appear
    • A rice-grain smear of fluoride toothpaste from the first tooth
    • Bottle finished before bed, then brush or wipe
    • Move toward an open cup between twelve and eighteen months

    Worth watching for. White chalky bands along the gumline of the upper front teeth. That is the earliest sign of decay and it is still reversible.

  2. 3 to 5Our patients

    The practice years

    A full primary dentition, with the spacing between front teeth that looks like a gap problem and is actually a good sign for the adult teeth to come.

    At the practice

    • Checkup and cleaning every six months
    • X-rays once the back molars touch and we can no longer see between them
    • Habit review for thumbs and pacifiers
    • First proper ride in the chair, usually without a parent's lap

    At home

    • Pea-sized fluoride toothpaste from age three
    • Twice a day, and a parent does the night pass
    • Floss wherever two teeth touch
    • Treats with meals rather than spread across the afternoon

    Worth watching for. A thumb or pacifier habit that is still going strong at four. It is far easier to unwind now than after the permanent incisors arrive.

  3. 6 to 9Our patients

    Wobbly teeth and new molars

    The mixed dentition. First permanent molars erupt behind the baby teeth around six without anything falling out first, and the lower incisors start to shed.

    At the practice

    • Sealants on the permanent molars as soon as the grooves are fully erupted
    • The age seven orthodontic check for crossbites, crowding and arch width
    • A mouthguard scan if a contact sport has started
    • Brushing coached against the new molars, which kids consistently miss

    At home

    • A parent pass at night until they can tie their own shoelaces, roughly seven or eight
    • Flossing becomes non-negotiable where the molars touch
    • New permanent teeth often come in yellower than baby teeth, which is normal
    • Water between meals, not juice

    Worth watching for. An adult tooth coming in behind a baby tooth that will not wiggle out. Call us, it usually needs a hand.

  4. 10 to 13Our patients

    The last baby teeth go

    Canines and premolars shed, second permanent molars arrive around twelve, and the bite settles into something close to its adult shape.

    At the practice

    • Sealants on the second molars
    • Orthodontic timing reviewed at each checkup
    • Wisdom teeth first appear on an X-ray around twelve, so we start tracking them
    • Gum health check, because hormonal gingivitis begins in this window

    At home

    • Independence with a spot check, not a handover
    • Interdental brushes or floss threaders once braces are on
    • A replacement mouthguard each season, they outgrow them fast
    • Sports drinks are the single biggest new enamel risk at this age

    Worth watching for. Puffy gums that bleed when brushed. That is gingivitis, not a sign to brush less.

  5. 14 to 18Our patients

    Their mouth, their habits

    A full permanent dentition apart from the third molars. Enamel is mature but the diet and the schedule are working against it.

    At the practice

    • Checkups booked around practices and exams, including our Saturday mornings
    • Whitening once growth and any orthodontic work have finished
    • Wisdom tooth position reviewed and referred if they are heading for trouble
    • Straight talk about vaping, energy drinks and mouth piercings, with the parent out of the room if that helps

    At home

    • Retainer wear if braces or aligners are done
    • A guard for grinding, which shows up around exam season
    • Brushing twice a day is the floor, not the goal
    • Their own reminders, not yours

    Worth watching for. Chalky white marks appearing around brackets. That is decalcification and it is permanent once the braces come off.

  6. 18 to 19Transitioning

    Handing over the chart

    Growth is essentially complete and wisdom teeth are the open question. From here the care a mouth needs is adult care.

    At the practice

    • We care for patients from the first tooth up to the nineteenth birthday
    • Current patients are welcome through the summer after high school, so nobody is dropped mid-treatment
    • At the last visit we send records, X-rays and a short summary wherever you ask
    • We will name two or three general dentists in the Treasure Valley who we would send our own families to

    At home

    • Ask for a copy of the chart before a college move
    • Keep the retainer, it does not stop mattering at eighteen
    • Register with a dentist near campus rather than waiting for a holiday
    • Know your own insurance details for the first time

    Worth watching for. The gap year where nobody books a checkup. It is the commonest reason a first adult visit starts with bad news.

  7. Grown-upsWe refer

    Parents, and grandparents

    We do not treat adults, and we would rather explain what changes than pretend it is all the same. Adult mouths fail differently from children's.

    What changes

    • Gum disease, not decay, becomes the main reason adults lose teeth
    • Dry mouth from common medications raises decay risk sharply in later life
    • Decay on exposed root surfaces is a specifically older-adult problem
    • Worn enamel, cracked cusps, crowns, implants and dentures are all general and restorative dentistry

    At home

    • The same two minutes twice a day, with interdental cleaning that actually reaches
    • Tell your dentist every medication, including the ones that seem unrelated
    • Book your own checkup on the same day as your child's if it helps you remember
    • Ask us for a referral, we keep a short list

    Worth watching for. Parents who have not been seen in years while their children never miss a visit. We see it constantly, and we will always give you a name.

The age we hand over

Little Molars treats children from the first tooth up to the nineteenth birthday. Patients already in treatment are welcome through the summer after high school so nobody is dropped part-way. At the final visit we send records and X-rays wherever you ask, and we will name general dentists in the Treasure Valley we would send our own families to.

General information, not dental advice. Every child develops on their own timetable and a few months either side of these ranges is normal.

Tap a tooth, or slide through the months

When do baby teeth show up?

Every child is on their own schedule. Most have all 20 baby teeth by age 3, and a few months early or late is completely normal.

Pick any tooth to see when it usually arrives and when it wiggles loose.

Based on American Dental Association eruption charts. Ask us if teeth are more than 6 months early or late.

Two minutes, twice, and four things after that

What actually matters at home

Parents are sold a lot of products. Here is the honest sort: the two things to protect on the worst evening of the week, the three that do the real work when you have the energy, and the two that are our job rather than yours.

Non-negotiable

Do these even on a bad night

  • Fluoride toothpaste, twice a day

    The right amount for the age, and spit rather than rinse afterwards so the fluoride film stays on the teeth and keeps working.

  • A parent pass at bedtime

    Let your child go first for the independence, then go over it properly yourself. Keep doing this until they can tie their own shoelaces.

Where cavities are won

Do these most days

  • Clean where two teeth touch

    A brush cannot pass a contact point. Floss or an interdental brush is the only thing that reaches, and back molars are where childhood cavities start.

  • Keep sugar to mealtimes

    How often it arrives matters more than how much. A dessert after dinner is gentler on enamel than the same sugar sipped across an afternoon.

  • Water between meals

    Not juice, not milk, not a sports drink. Water clears acid and keeps saliva doing the repair work it is built for.

Your job is only to turn up

Leave these to us

  • Sealants on new molars

    The grooves in a six-year molar are narrower than a bristle, so no amount of brushing reaches the bottom of them. Sealing closes the commonest cavity site in childhood.

  • A checkup every six months

    This catches what the rest of the list missed. It does not replace any of it, which is why it is in the last group rather than the first.

Brushing, properly

  1. Soft bristles, a small head, and whatever handle they will actually pick up. Manual and electric both work when the technique is right.
  2. Angle the bristles at about forty-five degrees to where the tooth meets the gum, not flat against the tooth.
  3. Short gentle circles in one place before moving on. Scrubbing hard scores the gumline and cleans less.
  4. Four quadrants, thirty seconds each. That is what the two-minute timer is dividing up.
  5. Do not skip the chewing surfaces, the tongue side of the lower molars or the back of the upper front teeth.
  6. Spit, do not rinse. Leaving the fluoride film on the teeth is half the point of using it.

Flossing, which is where the cavities are

  1. Start when two teeth touch

    For most children that is the back molars around age two to three, long before the front teeth ever touch. Anywhere a brush cannot pass is a flossing site.

  2. Floss picks count

    The best floss is the one that gets used. Picks are easier in a small mouth and easier for a parent reaching across a wriggling child.

  3. Hug the tooth

    Curve the floss into a C against one tooth, slide gently under the gum edge, up and out, then repeat against the neighbour. Do not snap it down between them.

  4. Once a day, at night

    Before the toothpaste, so the fluoride can reach the surfaces you just cleaned.

  5. A parent's job for longer than you think

    Most children do not have the dexterity to floss properly until around ten. Before that, expect to do it.

Interdental and the extras

Useful in the right mouth, and pointless in the wrong one. Here is who each of these is actually for.

  • Interdental brushes

    Small tapered brushes that fit gaps floss struggles with. Essential once braces are on, and easier than threading floss under a wire.

    Braces, wide gaps, tweens and teens
  • Floss threaders

    A soft loop that carries floss under an orthodontic wire or a space maintainer so you can still clean the contact point underneath.

    Braces and appliances
  • A water flosser

    Genuinely useful for rinsing debris out from around brackets. It is an addition to string floss, not a replacement for it.

    Braces, or a child who refuses floss entirely
  • Fluoride mouthrinse

    Worth adding from about age six, once a child can reliably spit everything out. At a different time of day from brushing, not straight after.

    Higher decay risk, ages 6 and up
  • Brushing the tongue

    A gentle sweep with the brush. Most childhood bad breath comes from the tongue, not the teeth.

    Any age
  • A mouthguard at night

    Grinding is common in childhood and usually needs nothing. A guard is for teens who are wearing enamel down or waking with jaw ache.

    Teens who grind

General information, not dental advice. Ask us at a checkup before starting a fluoride rinse or changing anything for a child under six.

Press start, then brush along

The 2-minute brush timer

Most kids stop brushing after 45 seconds. Our timer splits two minutes into four 30-second zones, so every tooth gets its turn.

  1. Top leftBack molars first, little circles
  2. Top rightSwap sides, do not forget the tongue side
  3. Bottom leftChewing tops and along the gums
  4. Bottom rightLast zone, then spit, do not rinse
2:00Ready when you are

Snack swaps teeth love

It is not only candy. Sticky, starchy and sipped-all-day snacks cause most of the cavities we see. Try these easy swaps.

Timing tip: serve treats with meals, not between them. Teeth need 2 to 3 hours to recover from each snack.

Straight answers, no scolding

The four habits parents ask about most

Teething, thumbs, pacifiers and bedtime bottles. Here is what actually matters for the bite, and what you can safely ignore.

Teething without the tears

Teething usually starts between 4 and 7 months. Drooling, chewing and fussiness are normal. High fever and diarrhea are not caused by teething, so call your pediatrician if those show up.

Worth doing

  • Chilled (not frozen) teething rings
  • Gentle gum massage with a clean finger
  • Wipe gums with a soft cloth after feeds

Skip these

  • Numbing gels with benzocaine for babies
  • Amber teething necklaces (choking risk)
  • Frozen rings that can bruise gums

Teething at home

Thumb sucking: when to worry

Sucking is a natural soothing reflex. Most kids stop on their own between 2 and 4. If it continues after permanent front teeth arrive, around age 6, it can push teeth forward and cause an open bite.

Worth doing

  • Praise thumb-free moments instead of scolding
  • Offer a comfort object at bedtime
  • Use a sticker chart for older preschoolers

Skip these

  • Bitter nail polish without talking to us
  • Shaming or punishment
  • Forcing it during stressful life changes

Pacifier habits and weaning

Pacifiers are easier to wean than thumbs, and they can be helpful for sleep in infancy. We suggest starting to limit them around 12 months and saying goodbye by age 2 to 3 to protect the bite.

Worth doing

  • Limit to naps and bedtime after the first birthday
  • Try the pacifier fairy or a trade for a toy
  • Replace cracked or worn pacifiers

Skip these

  • Dipping pacifiers in honey or sugar
  • Cleaning a pacifier in your own mouth
  • Clipping on long cords
Ask us about pacifiers
Pacifiers at home

Bottles, sippy cups and bedtime

Milk or formula pooling around teeth during sleep is a leading cause of early childhood cavities. Aim to move from bottle to open cup between 12 and 18 months.

Worth doing

  • Finish the bottle before bed, then brush or wipe
  • Offer only water in bedtime cups
  • Practice with an open or straw cup at meals

Skip these

  • Putting baby to bed with milk or juice
  • Carrying a sippy cup of juice all day
  • Adding sugar or cereal to bottles

Why age 7 is the number to remember

The American Association of Orthodontists recommends a bite check at 7, while the jaw is still growing and easy to guide. Most kids need nothing. For the few who do, early is easier.

  • Crossbites and narrow upper arches
  • Crowding with no room for adult teeth
  • Front teeth that stick out or do not meet
  • Jaw shifting to one side when biting
Book a visit
  1. Age 6

    First adult molars

    Six-year molars erupt behind the baby teeth. Perfect time for sealants.

  2. Age 7

    Ortho screening

    We check bite, spacing and jaw growth at a routine checkup, at no extra cost.

  3. Age 8 to 10

    Phase 1 if needed

    Expanders or Invisalign First guide growth, usually for 6 to 12 months.

  4. Age 10 to 12

    Baby teeth finish

    Canines and molars shed. We watch for crowding and impacted teeth.

  5. Age 12 to 14

    Phase 2 or full treatment

    Aligners or braces for teens who still need alignment.

  6. Age 16 to 19

    Retainers and wisdom teeth

    Retainers keep results. We X-ray wisdom teeth before they cause trouble.

Ages are typical ranges. Growth varies from child to child, and this is general education, not medical advice.

A knocked-out tooth costs more than a mouthguard

Kids without a mouthguard are far more likely to chip or lose a front tooth in contact sports. We scan, we fit, and your child picks the colors.

  • Custom-fitWhat we make

    Made from a 3D scan, thin enough to talk and breathe, in team colors. Best protection and comfort.

  • Boil and bite

    Store-bought and molded at home. Better than nothing, but bulkier and easy to chew through.

  • Stock

    Ready to wear, no fitting. Loose and uncomfortable, so kids tend to take them out.

Sports we fit guards for every season

  • Football
  • Hockey
  • Lacrosse
  • Basketball
  • Soccer
  • Wrestling
  • Skateboarding
  • Mountain biking
  • Martial arts
