Teething can be tough for babies and stressful for parents. When a baby is fussy, drooling, biting on everything, and having trouble sleeping, it is natural to want fast relief. That is why many parents look for teething gels, tablets, or other teething medicines marketed for sore gums.
But the U.S. Food and Drug Administration (FDA) has issued warnings about some teething products, especially those containing certain active ingredients. The main reason is safety: some teething medicines have been linked to serious side effects and may not be effective enough to justify the risk.
Here’s what parents need to know about why the FDA warns against teething meds, what the risks are, and what safer options can help. For families dealing with an infant who has a complicated health history, it can also help to read about related pediatric concerns such as Blue Baby Syndrome: Causes, Symptoms, Diagnosis & Treatment to understand why symptom changes in babies should always be taken seriously.
Why the FDA warns against teething medicines
The FDA warns against some teething products because they can cause harm, especially in infants and young children. Babies are more sensitive to medications than older children and adults, and even small amounts of certain ingredients can lead to dangerous reactions. That is one reason parents are urged to be cautious with teething medicines and to avoid assuming that a product is safe just because it is sold for babies.
Some teething products have been sold as gels, liquids, lozenges, and tablets. The concern is not just the format, but the ingredients inside them. The FDA has specifically raised concerns about products containing:
- Benzocaine
- Lidocaine
- Belladonna
- Certain herbal or homeopathic ingredients that are not well regulated
These ingredients may sound familiar because they are commonly used in other medical products. However, what is safe for adults or older children is not always safe for babies. That is why teething medicines should be evaluated carefully before being used at all.
Teething often overlaps with normal infant fussiness, which makes it easy to reach for a quick fix. Still, teething medicines are not a substitute for careful observation. If symptoms are unusually intense, parents should think beyond the gums and consider whether another illness may be causing the discomfort.
The main safety concerns
1. Benzocaine can cause a rare but serious blood disorder
Benzocaine is a numbing ingredient found in some oral gels and sprays. The FDA has warned that benzocaine can cause methemoglobinemia, a rare but potentially life-threatening condition in which the blood cannot carry enough oxygen.
Symptoms can include:
- Pale or gray skin
- Shortness of breath
- Fatigue or weakness
- Rapid heart rate
- Dizziness or confusion
This risk is especially concerning in infants because symptoms can develop quickly and may be mistaken for something less serious. Parents looking for teething medicines often want immediate comfort, but the possible harm can outweigh the short-lived benefit.
Even when a product seems gentle, the concern is not just how it feels in the moment. The bigger issue is whether a baby can safely process the ingredient after it is applied to the gums or swallowed. In many cases, the answer is no.
In practice, that means the safest choice is often to skip teething medicines with numbing ingredients and use simpler comfort measures first.
2. Lidocaine can be dangerous if swallowed
Lidocaine is another numbing medicine sometimes used for mouth pain. In babies, even a small amount can be risky if swallowed or absorbed through the mouth. This is one of the clearest reasons the FDA warns against teething meds that contain lidocaine.
Possible side effects include:
- Seizures
- Heart problems
- Severe drowsiness
- Breathing difficulties
The FDA has warned that oral lidocaine products should not be used for teething in infants and young children unless specifically directed by a healthcare professional for a different medical reason. In other words, teething medicines that include lidocaine are not a routine fix for gum discomfort.
This warning matters because teething products are often used at home, where dosing mistakes are easy to make. A tiny amount can go from a quick comfort measure to a serious exposure if the product is applied too often or if the child swallows more than expected.
Parents sometimes think a little extra gel will help a baby sleep, but more medicine does not mean more safety. With teething medicines, the margin for error can be very small.
3. Belladonna and some homeopathic products may be unsafe
The FDA has also warned about some teething tablets and gels labeled as homeopathic, especially those containing belladonna or inconsistent ingredient levels. Belladonna is a poisonous plant, and products made with it may have unreliable amounts of active compounds.
Potential symptoms of belladonna poisoning include:
- Flushing
- Dry mouth
- Trouble urinating
- Agitation
- Trouble breathing
- Seizures
Because babies cannot clearly explain how they feel, these reactions may be harder to spot in time. Even if teething medicines claim to be gentle or natural, that does not guarantee they are safe for infants.
Parents may assume that a product sold in a natural-health format has fewer risks, but that assumption can be misleading. Homeopathic labels do not automatically mean carefully standardized or suitable for babies, and inconsistent ingredients can make safety harder to judge.
That is why it helps to read the label closely and treat any unfamiliar ingredient as a reason to pause and ask a pediatrician or pharmacist.
4. Many teething products may not work well enough
Even when a teething product does not cause immediate harm, the FDA has concerns about whether it provides meaningful relief. Numbing agents may only work briefly, and babies may swallow the product quickly, reducing any benefit while still exposing them to risk.
In other words, the possible payoff is often too small compared with the safety concerns. For most families, that makes teething medicines a poor choice when simpler comfort measures are available.
That is especially true because teething discomfort often comes and goes. A product that briefly reduces gum sensitivity may not solve the bigger issue, which is an irritable baby who needs soothing, rest, and close attention rather than repeated medication use.
When the benefit is uncertain, it makes sense to start with the lowest-risk approach and reserve medication only for guidance from a healthcare professional.
What are the signs of teething?
Before trying any treatment, it helps to know what teething usually looks like. Common teething signs include:
- Drooling
- Swollen or tender gums
- Biting or chewing on objects
- Irritability
- Trouble sleeping
- A mild increase in temperature, but not a true fever
It is important to know that high fever, diarrhea, vomiting, or severe crying are not typical teething symptoms. If your baby has those signs, another illness may be the cause, and you should check with a healthcare provider.
Parents sometimes assume teething medicines are needed for every cranky day, but normal teething discomfort is often better managed with comfort and observation. If the baby is eating, gaining weight, and otherwise acting normally between episodes of fussiness, the problem is more likely mild teething than a serious illness.
Teething usually causes gum tenderness and a desire to chew. It should not make a baby look very sick. When a child seems unwell in a broader way, it is better to pause and ask whether something else is going on before turning to medication.
Knowing the difference can prevent unnecessary use of teething medicines and help parents notice warning signs sooner.
Safer ways to soothe a teething baby
The FDA and pediatric experts recommend non-medicinal comfort measures first. These are generally safer and can be effective.
1. Give your baby a firm teething ring
A clean, solid teething ring made for babies can help them chew and relieve gum pressure. Avoid liquid-filled teething toys if they can break.
Look for products that are easy to clean, made in one piece when possible, and large enough that the baby cannot fit the item completely into the mouth. A good teething ring can give the gums pressure in a safe, controlled way.
2. Use a cold washcloth
A clean, damp washcloth chilled in the refrigerator can provide soothing relief. Do not freeze it, since very cold objects can hurt the gums.
Some babies enjoy the texture of a washcloth because they can gum it gently. Parents can supervise closely while using this simple option, which makes it one of the easiest alternatives to teething medicines.
3. Gently massage the gums
Use a clean finger to rub your baby’s gums lightly. Some babies find this very comforting.
This can be especially helpful before naps or bedtime, when gum discomfort may be making it harder for the baby to settle. Gentle pressure often helps more than parents expect.
4. Offer safe chewing items
If your baby is old enough and already eating solids, talk to your pediatrician about safe options like chilled (not frozen) fruit in a feeder designed for babies.
Any chewing item should be age-appropriate, easy to supervise, and too large to become a choking hazard. Never give hard foods or small objects that can break off or be swallowed.
5. Try extra comfort and routine
Sometimes teething discomfort improves with simple soothing:
- More cuddling
- A calm bedtime routine
- Rocking or holding your baby
- Extra naps when possible
These approaches can make a noticeable difference without exposing a child to the possible risks that come with teething medicines.
Parents can also reduce frustration by keeping the baby’s environment calm. Lower noise, dim lights in the evening, and predictable routines may not stop teething, but they often make the discomfort easier to manage.
Even small comfort changes can help a baby settle without needing medication. For many families, that makes daily life easier and avoids unnecessary reliance on teething medicines.
What about over-the-counter pain medicine?
In some cases, a pediatrician may recommend acetaminophen or ibuprofen for significant discomfort, but these should be used carefully and only according to your child’s age and weight. Never give ibuprofen to babies under 6 months unless a doctor says to do so.
Do not use adult pain medication or give medicine just because a product is labeled “natural” or “baby-safe.” Always check with your pediatrician before giving any medicine to an infant. If you are also reading about prescription medicines and child safety, a resource like the FDA’s safety warning on benzocaine teething products is a helpful primary source.
Even when a doctor does recommend medicine, the goal is usually short-term comfort, not repeated treatment throughout the day. Parents should follow dosing instructions closely and avoid combining products unless a clinician says it is safe.
If you are uncertain about the correct dose, ask before giving anything. A careful question is always better than guessing when a baby is involved, and that is especially true with teething medicines or any other oral treatment.
Medical guidance can also help you tell whether the problem is teething, reflux, an ear infection, or something else that needs treatment beyond home care.
Common questions parents ask
Are teething gels safe for babies?
Many teething gels are not recommended for infants, especially those containing benzocaine or lidocaine. These ingredients can cause serious side effects and are not considered a good first choice for teething relief.
If a gel promises quick numbing, that may sound appealing, but the FDA warning exists because the risks can be much greater than the benefit. In general, families should be cautious about putting numbing products into a baby’s mouth.
Are homeopathic teething tablets safe?
Not necessarily. Some homeopathic teething products have been recalled or flagged by the FDA because of safety concerns, ingredient inconsistencies, or contamination risks. “Homeopathic” does not always mean harmless, and it does not automatically make teething medicines safer than other options.
In fact, many parents choose homeopathic products because they seem milder than standard medications. The problem is that “mild” on the label does not always match what is inside the product or how an infant’s body will react to it.
Why do some products still say they help teething?
Some products remain on the market because they are sold under different regulations or marketed in ways that can be confusing. The FDA warning is based on reported harms, ingredient risks, and the lack of clear benefit in infants.
That can make shopping for baby care products frustrating. A package may look official or reassuring, but parents still need to read ingredients carefully and verify that a product is truly appropriate for infants.
When in doubt, it is safer to choose non-medicinal relief than to rely on teething medicines with uncertain ingredients.
What if I already used a teething medicine?
If your baby has used a teething product and seems fine, they may not have any problem. But if you notice unusual sleepiness, trouble breathing, pale skin, weakness, vomiting, agitation, or seizures, seek emergency medical care right away.
If the exposure was recent and you are unsure what was used, call your pediatrician, poison control, or emergency services right away based on the severity of symptoms. Fast action matters if the product contains a risky ingredient.
When should I call the doctor?
Call your pediatrician if:
- Your baby has a fever that is high or lasts more than a day
- Symptoms seem severe or unusual
- Your baby is not feeding well
- You think a medicine may have caused a reaction
- You are unsure whether the pain is from teething or something else
If symptoms seem unrelated to teething or you are worried about another child health issue, your doctor can help you decide whether the problem is really teething or something else entirely.
Parents should also trust their instincts. If the baby looks unusually uncomfortable, weak, or different from their normal teething pattern, it is reasonable to ask for medical advice rather than relying on teething medicines at home.
How to choose safe teething products
If you are shopping for teething relief, keep these safety tips in mind:
- Avoid products with benzocaine or lidocaine for infants
- Be cautious with homeopathic teething tablets or gels
- Choose products made specifically for babies
- Look for products that are easy to clean and cannot break apart
- Check for recalls or FDA safety alerts before buying
Also, make sure any teething toy is age-appropriate. Small parts, detachable pieces, beads, and necklaces can be choking hazards. Teething necklaces, in particular, are not recommended because they can pose strangulation and choking risks.
If you want to avoid teething medicines altogether, choosing safe, simple products is often the most practical option. In many homes, a chilled ring and a little extra comfort do more than any gel or tablet can do.
Before buying anything, read the ingredient list and the age guidance carefully. A product that looks baby-focused may still contain ingredients that the FDA has warned against, so a quick check can prevent a serious mistake.
For families comparing products, the safest choice is usually the one that relies on comfort, supervision, and clear labeling rather than numbing chemicals.
The bottom line
The FDA warns against some teething medicines because the risks to babies can be serious, while the benefits are limited or unproven. Ingredients like benzocaine, lidocaine, and belladonna have been linked to dangerous side effects, and many teething products are not the safest choice for infants.
For most babies, the best approach is simple comfort care: a chilled teething ring, a cold washcloth, gentle gum massage, and extra soothing. If your baby seems very uncomfortable or has symptoms that do not seem like normal teething, contact a pediatrician.
When it comes to teething, safer relief is usually the better choice. Choosing carefully today can help parents avoid unnecessary risk from teething medicines and focus on comfort that really fits a baby’s needs.
For most families, the key takeaway is simple: teething medicines are not the first answer. Careful observation, gentle home care, and medical guidance when needed are safer ways to support a baby through this temporary stage.
If you are unsure, treat new or severe symptoms as a reason to seek medical advice rather than trying another teething medicine at home.
