When kids lose their first tooth

Your kindergartener bites a sandwich and tells you with a panicked face that their tooth is loose. Half an hour later they have visited every adult in the house with the news. You smile and try to remember roughly when this is supposed to happen and how concerned to be. Short answer: probably not concerned. Slightly longer answer, with the chart and the timing, is below.

The normal age range

Pediatric dental practice in the US uses the following ranges as typical. These come from the American Academy of Pediatric Dentistry and from large population studies.

• Lower central incisors (the two front bottom teeth): 6 to 7 years old
• Upper central incisors (the two front top teeth): 6 to 8 years old
• Lateral incisors (the ones next to the centers): 7 to 8 years old
• First molars (back, the ones on the chewing surface): 9 to 11 years old
• Canines (the pointy ones): 9 to 12 years old
• Second molars (very back): 10 to 12 years old

Note that the first tooth lost is almost always one of the lower central incisors. If your kid's first wiggler is a top tooth or a side tooth, that's still within the normal range — but a quick dental check-in is reasonable to make sure the adult tooth underneath is positioning correctly.

The order mirrors the order they came in

Teething goes in a predictable order: lower fronts first, then upper fronts, then sides, then molars and canines. Tooth loss mirrors that. The first teeth to erupt are typically the first to fall out. Knowing this means you can roughly predict your kid's pattern from their baby photos.

This also means that early teethers tend to be early losers. If your baby got their first tooth at 4 months (early), they often lose their first tooth closer to 5 years (early end of normal). Babies who teethed late often lose their first tooth closer to 7 years.

Why it happens when it does

Baby teeth don't fall out because they're "old." They fall out because the adult tooth growing under them dissolves the root of the baby tooth from below. Over months, the baby tooth's root is reabsorbed until only the crown is left, held in by very little tissue. Eventually it wobbles loose and falls out.

That process is happening invisibly for months. The wiggle stage is just the visible final week. By the time your kid notices the looseness, the adult tooth is usually within weeks of erupting.

What "early" looks like (before 4)

A baby tooth lost before age 4 is uncommon and worth a dental visit. Possible causes:

• Trauma. A fall, a bump, a soccer ball to the mouth. If the tooth gets knocked out by impact, it's gone. Save the tooth in milk and call the dentist within an hour, but for baby teeth most dentists don't try to reimplant.
• Cavity damage. A severe cavity can destroy a tooth's structure. Once the tooth is non-functional, the dentist may remove it.
• Periodontal disease in the rare hereditary form. Very uncommon, but worth ruling out.
• Underlying medical condition. Some rare metabolic and developmental conditions affect tooth integrity. Your pediatric dentist will screen.

Don't panic, but don't shrug it off. A dental visit within a week of an early tooth loss is the right call.

What "late" looks like (after 8)

If your 8-year-old has lost zero teeth, your pediatric dentist may take an X-ray to look at the adult teeth underneath. Possible explanations:

• Late developer. Most common. Some kids' teeth simply come and go later. If the X-ray shows adult teeth in normal position, you wait.
• Ankylosis. A baby tooth fused to the jawbone. Rare but treatable. The dentist will plan removal.
• Missing adult tooth. If there's no adult tooth under the baby tooth, the baby tooth may never fall out. The dentist will discuss options (let it stay, plan a future implant).
• Crowding. If adult teeth come in crowded, they sometimes erupt behind the baby teeth ("shark teeth"). Usually resolves on its own with a few months of patience. Sometimes needs a quick dental visit to remove the stubborn baby tooth.

Shark teeth: when the adult comes in behind the baby tooth

This freaks parents out and is almost always fine. The baby tooth's root didn't fully reabsorb, and the adult tooth came in behind it. Most of the time the baby tooth falls out within 4 to 8 weeks as the tongue pushes against it and the adult tooth keeps moving forward. If it hasn't resolved in 8 weeks or if your kid is in pain, a dentist can remove the baby tooth in a 5-minute appointment.

The "should I pull it" question

Short answer: usually no. Long answer: only if it's hanging by a thread.

A tooth that's loose enough to come out on its own will come out on its own. A tooth that you have to wrench out wasn't ready. Pulling early can:

• Hurt more than necessary.
• Leave a piece of root behind, which the dentist then has to deal with.
• Bleed more than a clean loss would.
• Slightly increase infection risk.

The exception: if the tooth is hanging sideways, the kid can't eat, or it's flopping enough to be a choking concern. In those cases, a clean tug with a tissue is fine — but if you're not sure, call your dentist's after-hours line. Most pediatric dentists will talk you through it on the phone.

The tooth-loss event itself

When the tooth finally comes out, the socket will bleed for a few minutes. Have your kid bite down on a gauze pad or a clean washcloth for 5 to 10 minutes. The bleeding stops quickly. If it doesn't stop within 30 minutes of pressure, call the dentist.

For the next 24 hours:

• Soft foods only. No popcorn, no hard pretzels.
• Gentle brushing around the area, not directly over the socket.
• Salt-water rinses 2 or 3 times a day, especially after meals.
• Avoid hot drinks for the first few hours.

By day 3 they'll be back to normal eating.

Tooth fairy logistics

Up to you, the family. A few practical notes:

• The current average tooth-fairy payment in the US is roughly $5 to $6 per tooth (Delta Dental's annual survey). Some families do $1. Some do $20. Set a household rate early so siblings don't compare.
• Have a small pouch by the bed. Sticking a tooth under a pillow is hard if the kid is restless. A small fabric pouch on the nightstand is easier on the tooth fairy who must operate stealthily at 11pm.
• Keep the tooth if you want. Some parents save them in a labeled bag. Others toss them. There's no right answer.

When to call the dentist

Most tooth losses don't need a dentist call. Call if:

• The tooth is lost before age 4 from any cause.
• Bleeding doesn't stop within 30 minutes of firm pressure.
• The adult tooth comes in behind the baby tooth and isn't resolving after 8 weeks.
• Your kid is past 8 and hasn't lost a single tooth yet.
• Pain doesn't fade within a day or two.
• You see white pus or smell foul breath from the socket — signs of infection.
