• An adult tooth that hasn’t erupted on schedule is usually impacted, meaning it’s stuck under the gum or bone, often blocked by a baby tooth, crowding, or an unusual growth angle. Upper canines are common offenders.
• Treatment is typically exposure and bonding: an oral surgeon uncovers the tooth, bonds a small bracket and chain to it, then the orthodontist uses that chain to slowly guide the tooth into place over several months.
• Sedation options like nitrous oxide, local anesthesia, and IV sedation are available so your child stays comfortable throughout, and the procedure itself usually takes under an hour.

If you’ve noticed one of your child’s adult teeth is taking its time, or their pediatric dentist mentioned a tooth that “hasn’t come in yet,” you’re probably looking for answers and wondering how worried you should be. The good news is that this is a common issue, and it’s very treatable. Here’s what’s actually going on, and what usually happens next.

Why an Adult Tooth Might Not Erupt

Every tooth follows its own timeline, but there’s a general schedule most kids’ teeth stick to. When a tooth misses that window by several months or longer, it’s often because something is blocking its path. This is called an impacted tooth, and it means the tooth is stuck, partially or fully, beneath the gum or bone instead of coming in where it belongs.

A few common culprits: a baby tooth that never fell out and is sitting in the way, crowding that leaves no room for the new tooth to travel through, an unusual angle of growth, or extra teeth that create a physical obstruction. The upper canines, sometimes called eye teeth, are the most frequent offenders after wisdom teeth, since they erupt later than most other adult teeth and have a longer path to travel. An impacted canine may cause no noticeable symptoms at all, which is why routine dental checkups and X-rays are so important for catching it early.

Often, a pediatric dentist or orthodontist spots the issue first, either because a baby tooth is still hanging on well past when it should have loosened, or because an X-ray shows a tooth that isn’t tracking toward its normal position. From there, most general dentists and orthodontists refer out to an oral surgeon for the next step, since this is a surgical procedure that requires specialized training.

What Happens Next: Exposure and Bonding

If a tooth is impacted and unlikely to erupt on its own, the standard treatment is a procedure called exposure and bonding, sometimes referred to as tooth chain surgery or expose and bond. It sounds intimidating, but it’s a well-established, minor surgical procedure that oral surgeons perform regularly.

Here’s the process in simple terms. First, if a baby tooth is still in the way, it’s removed. Then the surgeon gently lifts the gum tissue covering the impacted tooth to expose it. A small orthodontic bracket is bonded directly to the tooth’s surface, and a tiny chain is attached to that bracket. The gum tissue is repositioned, with the chain left accessible so the orthodontist can connect it to the braces already in place.

From there, the orthodontist takes over. Over the following months, gentle, gradual force is applied through the chain to slowly guide the tooth down into its correct spot in the dental arch. It’s a slow process by design; moving a tooth too quickly can damage the root or surrounding bone. Most patients see steady progress over several months, and the payoff is a tooth that erupts into proper alignment instead of being extracted.

Why bother saving the tooth instead of just pulling it? Canines especially play an important role in a healthy bite, and losing one means either a gap that needs to be closed orthodontically or a more involved restoration down the road. Exposure and bonding gives your child’s own tooth a real shot at doing its job for the rest of their life.

What About Sedation? Will My Child Be Comfortable?

This is usually the question parents care about most, and understandably so. The procedure itself is quick, often under an hour, but it’s still surgery, and it’s natural to want your child to be calm and pain-free throughout.

Most pediatric oral surgery offices offer a range of sedation options tailored to the child’s age, anxiety level, and the complexity of the procedure. 

• Nitrous oxide, or laughing gas, is a good option for kids with mild anxiety who just need to take the edge off. 
• Local anesthesia numbs the surgical area directly and is typically used alongside other methods to keep the area pain-free. 
• For children who are more anxious, younger, or need a deeper level of relaxation, IV sedation is often recommended, which allows the child to remain comfortable and unaware of the procedure as it happens.

A good oral surgery team will walk you through each option during the consultation and help you choose the approach that fits your child best. There’s no one-size-fits-all answer here, and that’s exactly the point.

When to Get It Checked

If your child’s dentist or orthodontist has flagged a tooth that hasn’t come in on schedule, or you’ve noticed a longstanding baby tooth that just won’t budge, it’s worth getting an evaluation sooner rather than later. Early evaluation gives everyone more options and generally makes for a smoother, shorter treatment process.
