Baby Teething: Symptoms, Timeline, and Relief That Works

BabyInsight TeamMarch 11, 20269 min read

One morning your baby wakes up drooling like a faucet, gnawing on their fist, and crankier than usual. You peek inside their mouth and there it is: a tiny white ridge pushing through the gum. Teething has arrived. It is one of those milestones that can stretch over two years, and it comes with a lot of myths that can lead parents down the wrong path. Let's sort out what is actually teething, what is not, and what genuinely helps.

When Does Teething Start?

Most babies cut their first tooth somewhere between 6 and 10 months, but the range is wide. Some babies are born with a tooth (natal teeth, which is rare but real). Others do not see their first tooth until after their first birthday. Both ends of the spectrum are normal.

If your baby has no teeth by 12 months, mention it at their next well-child visit. It is almost never a problem, but your pediatrician may want to take a look.

The Teething Timeline — Which Teeth Come When

Teeth tend to arrive in a fairly predictable order, though there is always that one baby who does things completely backwards. Generally:

  • 6 to 10 months: Lower central incisors — the bottom front two. These are usually first.
  • 8 to 12 months: Upper central incisors — the top front two. Now your baby has a real smile.
  • 9 to 13 months: Upper lateral incisors — the ones flanking the top front teeth.
  • 10 to 16 months: Lower lateral incisors — completing the front row.
  • 13 to 19 months: First molars — these are the big ones. Larger surface area means more gum discomfort.
  • 16 to 22 months: Canines (the pointy ones) — fill in the gap between incisors and molars.
  • 25 to 33 months: Second molars — the last to arrive, way in the back.

By age 2.5 to 3, most children have all 20 primary teeth. Then you get a few years of peace before they start falling out again.

Actual Teething Symptoms

Here is where it gets important to separate what teething actually causes from what parents (and even some grandparents) attribute to teething. The real symptoms are relatively mild:

  • Increased drooling: Some babies soak through bibs. This is the most universal symptom.
  • Gum sensitivity and swelling: The gums over an emerging tooth may look red and puffy.
  • Chewing on everything: Fingers, toys, your shoulder, the dog's ear. Pressure on the gums feels good.
  • Mild fussiness: Emphasis on mild. Your baby might be a bit more irritable than usual, especially in the day or two before a tooth breaks through.
  • Slight decrease in appetite: Sore gums can make eating less appealing, particularly with a spoon or hard foods.
  • Disrupted sleep: Some babies wake more at night when a tooth is actively cutting through.

What Teething Does NOT Cause

This is the part most parents do not hear, and it matters a lot for your baby's health.

Teething does not cause: high fever (above 100.4F/38C), diarrhea, vomiting, body rash, runny nose, or ear pulling/infections. If your baby has any of these symptoms, they are likely sick with something unrelated to teething and may need medical attention. Do not dismiss a fever as "just teething."

So why does everyone think teething causes all of these things? Timing. Babies start teething around 6 months, which is exactly when maternal antibodies passed during pregnancy start to decline. This means babies get more infections right around the same time teeth are coming in. The teething gets blamed for the fever, the diarrhea, and the runny nose, when in reality it is a coincidence of timing.

This matters because dismissing a real infection as teething can delay treatment. A study in Pediatrics found that attributing fever to teething led to delayed diagnosis of urinary tract infections, ear infections, and other conditions.

Safe Teething Relief — What Actually Works

The good news is that there are several safe, effective ways to help your teething baby:

  • Gum massage: Wash your hands and rub your baby's gums with a clean finger. The pressure feels good and you are right there to comfort them. This is the simplest and often the most effective approach.
  • Chilled teething ring: Put a solid teething ring in the refrigerator (not the freezer). Cold numbs the gums slightly and the pressure of biting helps. Frozen teething rings are too hard and can actually hurt inflamed gums.
  • Cold washcloth: Wet a clean washcloth, wring it out, and chill it in the fridge. Let your baby chew on it. Simple, free, and effective.
  • Cold foods for babies 6 months and older: Chilled fruit in a mesh feeder, cold yogurt, or frozen breast milk popsicles can all provide relief and nutrition at the same time.
  • Pain medication when needed: Acetaminophen (Tylenol) for babies 3 months and older. Ibuprofen (Motrin, Advil) for babies 6 months and older. Use as directed by your pediatrician. These are safe, effective, and there is no reason to let your baby suffer when a tooth is clearly causing real discomfort.

Teething Products to Avoid

Not everything marketed for teething is safe. Some popular products carry real risks.

Benzocaine Gels (Orajel and Similar)

The FDA has issued multiple warnings against using benzocaine products in children under 2. Benzocaine can cause methemoglobinemia, a rare but serious condition where oxygen levels in the blood drop dangerously. In 2018, the FDA asked manufacturers to stop selling over-the-counter benzocaine products for teething. If you have an old tube in the medicine cabinet, throw it away.

Amber Teething Necklaces

These are marketed with the claim that body heat releases succinic acid from the amber, which then acts as a pain reliever. There is no scientific evidence that this works. What there is evidence for: strangulation risk and choking hazard. The FDA has warned against them, and multiple infant deaths have been linked to teething necklaces. They are not worth the risk, no matter what the marketing says.

Homeopathic Teething Tablets

In 2016 and again in 2017, the FDA warned about homeopathic teething products (including popular brands sold in major pharmacies) after reports of seizures and at least 10 infant deaths. Testing found inconsistent levels of belladonna, a toxic plant extract, in these products. The FDA continues to advise against their use.

The simplest options are the safest: A clean finger, a chilled teething ring, and age-appropriate pain medication if needed. You do not need fancy products. Your pediatrician can recommend exactly what is appropriate for your baby's age.

First Dentist Visit

The American Academy of Pediatric Dentistry recommends that your baby see a dentist by their first birthday or within 6 months of the first tooth appearing, whichever comes first. This might seem early, but the first visit is mostly about establishing a relationship with the dentist, checking for any early issues, and getting guidance on oral care.

Start brushing as soon as the first tooth appears. Use a soft-bristled infant toothbrush with a rice-grain-sized smear of fluoride toothpaste. Yes, fluoride. The ADA recommends fluoride toothpaste from the first tooth. The amount is so small that even if your baby swallows it (and they will), it is safe.

When Teeth and Other Things Overlap

Teething happens alongside so many other changes in the first two years that it can be hard to sort out what is causing what. Fussiness during teething might actually be a reaction to a recent vaccine. Sleep disruption might be a developmental regression rather than tooth pain. A fever is almost certainly not from teething.

BabyInsight can help you see patterns by tracking symptoms alongside teeth, vaccines, and developmental milestones. When you can look back and see that your baby's fussiness started exactly when they got their 6-month shots rather than when a tooth appeared, it changes how you respond. Good data makes better parenting decisions, and you do not have to rely on memory when you are running on three hours of sleep.
