Your child just handed you a tiny tooth with a little blood on it, the tooth fairy is due tonight, and you're not sure whether keeping it is sweet or slightly strange. Keeping baby teeth is common, and it doesn't have to be strange at all. Here's how to preserve baby teeth so they stay clean for years, which container suits which goal, and the few habits that keep a tooth keepsake from sliding into creepy territory.

What to do with baby's first tooth (both of them)

There are two "first teeth," and only one of them can go in a box.

The first tooth to come in usually appears somewhere around 6 months and stays put for years. For that milestone, the keepsake is the record. Write the date in the baby book and take a photo of the new tooth, or of the drool-covered grin around it.

The first tooth to fall out usually goes around age 6, and it's often one of the bottom front teeth. Kids have 20 baby teeth in all, and most lose the last ones in their preteen years. HealthyChildren.org, the American Academy of Pediatrics' site for parents, covers the typical timeline, and your child's dentist can tell you what to expect.

That six-year gap matters if you're buying or receiving a first tooth keepsake box as a baby shower gift. It will sit empty for years, so a simple design that suits a 6-year-old, and the adult they become, beats a babyish one. If you're the gift-giver, add a line to the card like "For the first tooth they lose, around age 6" so the parents remember what it's for.

How to clean a baby tooth before you store it

In short: rinse, scrub, soak if you like, then dry it longer than you think you need to.

A tooth that falls out on its own is usually small, with a hollow or jagged base. That's normal: the root wears away as the adult tooth pushes up underneath. A tooth your dentist pulls may have more root and tissue attached, so if a tooth is coming out at an appointment, ask ahead of time to take it home. Offices can usually rinse it and send it home in a small container.

1. Rinse it over a strainer or bowl. Run cool water over the tooth to wash off any blood. Don't rinse it over an open drain, because a baby tooth can vanish down the sink in a second.
2. Scrub gently. Use a spare soft toothbrush and a drop of mild dish soap, working around the base where tissue clings. Skip pins and toothpicks, which can chip the thin edges.
3. Soak briefly, if you want. For an extra clean, soak it for a few minutes in regular drugstore hydrogen peroxide (the standard brown bottle, not a stronger salon or "food-grade" version), then rinse with plain water. This is an adult-only step, so keep the bottle out of reach. Skip bleach and boiling; both are harsher than a tooth needs.
4. Dry it completely. Set the tooth on a folded paper towel in a small open dish for at least 24 hours, or 48 if your home is humid. Moisture trapped in a closed container can lead to a musty smell or mold, so don't rush this part.

Put the drying dish up high, not on a counter edge or nightstand. A tooth is choking-size for a baby or toddler sibling, and so are the vials, stoppers and jewelry pieces below.

Tooth fairy box vs. vial vs. jewelry vs. keepsake box

In short: a sealed vial protects a tooth best, a keepsake box hides it best, and the two together beat any single option.

How to choose:

• If you only need somewhere to put tonight's tooth, a tooth fairy box is enough. Move the tooth into something sealed afterward.
• If you're keeping more than one tooth, use one vial per tooth, each labeled. A jar of mixed teeth is exactly the look you're trying to avoid.
• If you want to wear it, a locket lets you take the tooth out later; a resin setting doesn't. Before mailing a tooth to a maker, ask how they handle it, use tracked shipping, and keep at least one other tooth at home. DIY resin kits are an adult-only project with gloves and good ventilation, so practice on a pebble first.
• If you already have a keepsake box with a tooth compartment, use it, but put the tooth in a small vial first so it can't rattle or slip loose.

Our take: for most families, combine a vial and a keepsake box. One small sealed vial, labeled, tucked into a keepsake box with the other first-year things. It's clean and protected, and nobody sees a tooth unless they open the lid on purpose.

How to keep a tooth keepsake from looking creepy

Baby teeth earn their creepy reputation from a few habits: a sandwich bag of loose teeth in the junk drawer, a jar of all 20 with no labels, dried blood still on a tooth, or a tooth sitting out on a living room shelf. Skip those, and a tooth reads as a keepsake instead of a leftover.

Clean and sealed beats loose

A clean, dry tooth in a closed container looks intentional. A loose one in a drawer looks forgotten. The cleaning steps above do most of the work here.

Keep fewer, and pick them on purpose

Decide your plan before the first wobble, so you're not making it up at bedtime:

• The first tooth lost, only
• The first and the last
• One per year, from about age 6 onward
• All 20, each in its own labeled vial or numbered slot
• None, keeping the record instead (more on that below)

Show the story, not the tooth

The photo of the gap-toothed grin says more than the tooth does. Pair the vial with that photo, the date and one line about how it came out, like "wiggled loose on an apple at Grandma's." The tooth can stay in the box behind them.

Display small, and in private spaces

If you want something on the wall, try a small shadow box holding the photo, a handwritten label and the sealed vial fixed in place behind glass. Hang it securely at adult height in a bedroom or hallway, rather than in the kitchen or living room where guests gather.

Give your child a vote

It's their tooth. Some kids find saved teeth fascinating, and some think it's gross. Ask once they're old enough to have an opinion, and don't be surprised if the answer changes in the teen years.

How to label baby teeth so you know whose is whose

Baby teeth from two siblings look almost identical, and you won't remember in 15 years which vial belonged to whom. Label each tooth the day you seal it, using a fine-tip permanent pen on a small tag or sticker. Then put a matching note inside the box lid in case the tag falls off.

Copy this format:

"[Name] · [which tooth, e.g., bottom front, left] · lost [month, day, year] · age [X] · [how it came out]"

Write "left" and "right" from your child's side, not yours. For dentist-level precision, US dentists label the 20 baby teeth with letters A through T, and you can ask for a tooth chart at the next checkup. Plain words work just as well.

It's the same habit that keeps a handprint ornament meaningful years later: name and date on the day, not someday.

Keeping the tooth when the tooth fairy "takes" it

The tooth fairy and your keepsake plan can clash on night one. Families usually handle it one of three ways.

• The quiet swap. The tooth fairy takes the tooth, and you move it to the drying dish and later its labeled vial. Store it where a curious 7-year-old won't stumble on it, and decide ahead of time what you'll say if they do.
• The return. The tooth fairy leaves the first tooth behind with a note, so it's kept in the open.
• The child's choice. Your child decides whether to leave the tooth or keep it and leave a note instead.

A note for the return:

"I picked up your tooth tonight, but this one is too special for my collection. First teeth belong with your family, so I left it right here for you to keep safe. Keep up the good brushing! — The Tooth Fairy"

A note your child can leave if they want to keep it:

"Dear Tooth Fairy, can I keep my tooth this time? I drew you a picture of it instead."

A tooth in a small box is far easier to find under a pillow in the dark than a loose one in the sheets. If the tooth goes under the pillow the same night, rinse it and pat it dry first, then do the full scrub and dry after the swap.

If a tooth gets swallowed or lost at school, a note to the tooth fairy works fine, and the date still goes on the record. If you're ever worried about a swallowed tooth, call your pediatrician.

Where to store baby teeth for the long haul

Once a baby tooth is clean, dry and sealed, it's stable. Enamel is the hardest material in the human body, so the storage spot matters more for the container and label than for the tooth.

• Good spots: a high closet shelf or a parent's jewelry box kept up high. Anywhere in the lived-in part of your home, where temperature and humidity stay steady. Once no one under 3 lives with you, a dresser drawer works too.
• Skip: bathrooms (steam), attics, garages and basements (heat, cold and damp), and sunny windowsills (faded labels, yellowed resin).
• Keep it on a high shelf or in a latched box while you have kids under 3 at home.
• When you move, pack it with jewelry and important papers, not in a general box of odds and ends.

Before you close the lid, run through this:

• ☐  Tooth rinsed and gently scrubbed
• ☐  Air-dried for at least 24 hours
• ☐  Container closes firmly
• ☐  Label with name, which tooth, date and age
• ☐  Matching note inside the box lid
• ☐  Stored up high, out of reach of babies and toddlers
• ☐  Date also logged somewhere else, like the baby book or a phone note

Baby tooth keepsake ideas that don't show the tooth at all

Sometimes the best tooth keepsake is the record. These work alongside a saved tooth, or instead of one.

• A tooth chart. Draw a simple mouth with 20 teeth, or use the chart that comes with many tooth fairy boxes, and write in the date as each tooth goes. Keep it in the keepsake box lid.
• The gap-toothed photo. Same spot, same pose, every lost tooth. Lined up years later, the photos tell the whole story in one row.
• A note by the height mark. If you mark heights on a growth chart, write "first tooth out" beside that year's line. It's one small reason some families choose a wall growth chart over an app: the milestones land in one place you can see.
• A time capsule entry. Tooth fairy notes and the tooth chart fit neatly into a yearly family time capsule, where they make a fun surprise to reopen.
• Nothing saved at all. Letting the tooth fairy truly take them is a fine choice. A dated photo and one line in the baby book keep the memory without keeping the tooth.

Whatever you decide, the method stays the same: clean it, dry it longer than feels necessary, then seal and label it the same day. Keep the one or two teeth you'll actually want to open again, store them somewhere private and out of small hands, and let the photo and the date carry the display.
