How to Make Teeth Come In Faster: What Actually Works

Tooth eruption is governed by more than 300 genes, and no home remedy, supplement, or device can override that genetic programming to make a tooth appear sooner than your body intends. The process depends on a precisely orchestrated cycle of bone remodeling around each developing tooth, and that cycle runs on its own clock. What you can do is remove the obstacles that slow eruption down, address nutritional or medical conditions that cause delays, and, in the case of orthodontic treatment, use clinically proven techniques to move teeth that are already present but stuck. The gap between what parents hope for and what the biology allows is wide, so understanding what genuinely matters saves both worry and money.

Why Teeth Run on Their Own Schedule

Every tooth sits inside a pocket of tissue called the dental follicle, and that follicle acts as the control center for eruption. It sends signals that trigger two coordinated events: bone above the tooth gets broken down to clear a path, while bone below the tooth gets built up to push it upward. The follicle manages this by switching specific genes on and off at precise times, controlling which cells dissolve bone and which cells form it. When the follicle’s signaling is disrupted, teeth simply do not erupt on schedule, and no external force can substitute for what the follicle does internally.¹ The follicle also coordinates things spatially: bone resorption happens above the tooth crown, while bone formation happens below it, with different genes expressed in the top and bottom halves of the follicle to make this work.²

This means eruption is not a matter of the tooth being “ready” and just needing a nudge. The surrounding bone has to be remodeled in a specific pattern, and the nerve supply at the root tip contributes to generating the eruption pressure itself.³ It is a multi-step biological project, not something you can hurry along from the outside.

What “Normal” Eruption Actually Looks Like

Parents frequently worry that their child’s teeth are late, but the normal range is broader than most people realize. The lower front teeth are typically the first to appear, followed by the upper front teeth, and the entire set of baby teeth takes roughly 22 months to come through from first to last.⁴ Variability is lowest during infancy and increases substantially with age, which means the window for “normal” first teeth is relatively narrow, but the window for later teeth (and especially wisdom teeth) is enormous.⁵

A baby who cuts a first tooth at four months and one who waits until twelve months can both be completely normal. For permanent teeth, the spread widens further. If your child’s teeth fall within a few months of the typical range and there are no other developmental concerns, there is almost certainly nothing wrong and nothing to fix.

Conditions That Genuinely Delay Eruption

While you cannot speed up a tooth that is developing on its natural timeline, you can identify and treat conditions that are actively slowing things down. These fall into nutritional, hormonal, and birth-related categories.

Vitamin D and Calcium

Children with low vitamin D levels are significantly more likely to have delayed tooth eruption. One study found that children who were vitamin D deficient had more than twice the odds of retaining baby teeth past the age when permanent teeth should have replaced them.⁶ A separate study confirmed that children with delayed eruption had significantly lower blood levels of both vitamin D and calcium, along with elevated parathyroid hormone, which is the body’s signal that calcium supplies are low.⁷

This does not mean that supplementing a healthy child with extra vitamin D will make teeth appear faster. It means that if eruption is noticeably delayed, vitamin D deficiency is worth checking for and correcting. Adequate vitamin D supports the bone remodeling that eruption depends on. A deficiency undermines that process.

Thyroid Problems

Hypothyroidism is a well-recognized cause of delayed eruption in both baby and permanent teeth. The thyroid hormones T3 and T4 play a direct role in normal development of the jaw and teeth, and when levels are too low, eruption slows or stalls. Congenital hypothyroidism, in particular, is associated with delayed eruption of both sets of teeth.⁸ Treating the underlying thyroid condition is the intervention; there is no tooth-specific workaround.

Premature Birth and Low Birth Weight

Babies born prematurely tend to get their first tooth later than full-term babies. In one study, preterm infants got their first tooth at an average of about 9.3 months compared to about 8 months for full-term infants. Babies with very low birth weight (under 1.5 kg) showed even greater delays, averaging nearly 10 months. However, when the researchers corrected for gestational age, the difference between preterm and full-term groups disappeared, suggesting that premature babies are not truly delayed relative to their developmental age.⁹ Complementary feeding, parity, and weight-for-gestational-age were all significant factors influencing when teeth appeared.¹⁰

The practical takeaway: if your baby was premature, count tooth eruption from the due date, not the birth date. That adjustment usually eliminates the apparent delay.

When a Tooth Is Stuck: Eruption Cysts and Impacted Teeth

Sometimes a tooth is ready to erupt but physically cannot get through. The two most common local obstacles are eruption cysts and impacted teeth, and how they are managed differs considerably.

An eruption cyst is a fluid-filled swelling that forms over a tooth just before it breaks through the gum. It looks like a small, translucent or bluish bump. When blood collects inside the cyst, it turns dark blue or purple and is called an eruption hematoma.¹¹ These look alarming, but the standard recommendation is to leave them alone. Most eruption cysts resolve on their own as the tooth pushes through, and monitoring without surgical intervention is generally effective.¹² If a cyst persists and truly blocks the tooth, a dentist can make a small incision to release the fluid, but this is rarely necessary.

Impacted teeth are a different problem entirely. An impacted tooth is one that has formed but is trapped in the bone or gum tissue because it is angled the wrong way, is blocked by another tooth, or has insufficient space. Upper canines are among the most commonly impacted permanent teeth. These will not come in on their own and require dental intervention, typically a combination of surgical exposure and orthodontic traction. A surgeon uncovers the tooth, bonds an attachment to it, and an orthodontist then uses braces or wires to gently guide it into the correct position over months.¹³

Surgical and Orthodontic Techniques That Actually Speed Things Up

For teeth that are impacted or being moved orthodontically, there are evidence-based techniques that genuinely accelerate movement. These are clinical procedures performed by dental professionals, not something you can replicate at home.

Corticotomy and Bone Scoring

When an impacted canine needs to be brought into the mouth, a technique called corticotomy-assisted traction can dramatically cut the time required. In one randomized controlled trial, impacted upper canines treated with corticotomy moved at an average rate of about 1.15 mm per month compared to 0.70 mm per month with conventional traction alone, and the overall treatment duration was reduced by about 29%.¹⁴ Another study found an even larger effect: forced eruption with an ostectomy-decortication technique took an average of 6.6 months compared to 21 months without it, making the treated teeth arrive more than three times faster.¹⁵

These techniques work by creating controlled, minor injuries in the bone around the tooth. The body responds with an inflammatory healing process that temporarily softens the bone, allowing the tooth to move through it more easily. This is the same principle behind micro-osteoperforations.

Micro-Osteoperforations

Micro-osteoperforations (MOPs) are tiny holes made in the bone near a tooth that needs to be moved. The procedure triggers a local inflammatory response that reduces bone density in the tooth’s path and speeds up movement. One study reported a 2.3-fold increase in the rate of orthodontic tooth movement with MOPs.¹⁶ The accelerated movement appears to be driven by increased cell turnover in the periodontal ligament, the tissue that connects the tooth root to the surrounding bone.¹⁷ A systematic review confirmed that MOPs consistently increase the rate of orthodontic movement across both animal and human studies.¹⁸

It is worth emphasizing that these techniques apply to teeth being moved orthodontically, not to baby teeth or permanent teeth erupting on a normal timeline. You cannot micro-perforate your child’s jaw to make a first tooth appear sooner, and no dentist would do so.

Vibration Devices

Commercially available vibration devices (like AcceleDent) are marketed as a way to speed up orthodontic treatment. A systematic review found that high-frequency vibrations in the range of 60 to 120 Hz showed promise for accelerating tooth movement, increasing the rate of space closure with braces and allowing faster aligner changes.¹⁹ The evidence here is still mixed, and the effect sizes are modest compared to surgical approaches. These devices are relevant only during active orthodontic treatment, not for natural eruption.

Low-Level Laser Therapy

Low-level laser therapy has been studied as a non-invasive way to speed up orthodontic movement. One randomized trial found that a 970 nm laser produced faster tooth movement in the treated group, but the overall treatment time was virtually identical between the laser and placebo groups.²⁰ A meta-analysis concluded there is no reliable evidence that laser therapy can accelerate orthodontic tooth movement in a clinically meaningful way.²¹ So while the idea is intriguing, the evidence has not held up well enough to recommend it.

Teething Comfort Is Not Eruption Speed, but It Is What Parents Really Need

Many parents searching for ways to make teeth “come in faster” are actually looking for relief from teething symptoms: the fussiness, drooling, and sleep disruption that come when teeth are actively breaking through the gums. Addressing discomfort does not accelerate eruption, but it is the practical problem that needs solving.

A clinical trial comparing non-drug approaches found that chilled teething rings produced the best results for symptom relief and parent satisfaction, followed by gentle gum rubbing and comforting the baby through cuddling.²² A systematic review confirmed that teething rings were the most effective non-drug intervention, particularly for drooling, gum irritation, disrupted sleep, and crying.²³

Cold pressure is the common thread. A chilled (not frozen) teething ring provides both counter-pressure on the swollen gum and mild numbing from the cold. Frozen objects can damage delicate gum tissue, so aim for refrigerator temperature. Rubbing the gums with a clean finger works on the same counter-pressure principle and has the advantage of being always available.

What to Avoid

The teething aisle is full of products that range from useless to dangerous. Two deserve special mention because they remain popular despite clear evidence against them.

Benzocaine Gels

Topical numbing gels containing benzocaine (sold under brand names like Orajel) were once widely used for teething pain. The FDA issued a safety warning because benzocaine can cause methemoglobinemia, a condition where the blood’s ability to carry oxygen drops dangerously. Symptoms include blue-tinged skin, difficulty breathing, seizures, and in severe cases, coma.²⁴ Children under two are especially vulnerable. The FDA recommends against using benzocaine products for teething in children under that age.

Amber Teething Necklaces

Amber necklaces are marketed with the claim that body heat releases succinic acid from the amber beads, which then gets absorbed through the skin to reduce inflammation. Testing has shown there is no evidence that succinic acid is released intact at body temperature, and even if it were, the amounts would be far too small to produce any anti-inflammatory effect.²⁵ Meanwhile, the necklaces present real physical dangers. Laboratory testing found that about half of amber teething necklaces failed to open under the 15 pounds of force specified in safety standards for children’s jewelry, and 80% failed to release at the much lower force that can obstruct a young child’s airway.²⁶ Despite widespread awareness of strangulation and choking risks, many caregivers continue to use them with inadequate safety precautions.²⁷

When Eruption Timing in Humans Is Unusual by Design

Something that rarely gets mentioned in parenting forums is that human tooth eruption is, by its nature, oddly timed compared to our closest primate relatives. In chimpanzees, the peak growth spurts of tooth roots line up neatly with the ages when those teeth break through the gum. In humans, the root growth spurts happen well before the teeth actually erupt. Human first molars, for instance, erupt around age six, but the surge in root growth that prepares them occurs earlier, while the teeth are still buried in bone.²⁸

This disconnect appears to be an evolved feature of our unusually long childhood. Humans grow slowly, wean late, and develop their dentition on a stretched-out schedule that matches our extended period of dependence. The teeth are biologically “ready” before they appear, waiting for the surrounding jaw to grow enough to accommodate them. This is part of why trying to rush eruption is fighting against a deeply embedded evolutionary strategy rather than fixing a problem. The teeth are not late. The timeline is simply longer than it looks from the outside, and that elongated schedule is part of what makes us human.
