When Do Babies Start Teething? Signs, Timeline & Proven Remedies

Your baby's been extra fussy, drooling more than usual, and gnawing on everything in sight. You're wondering if those first teeth are finally making their grand entrance—and when this phase might actually end.

Most babies start teething between 4 and 7 months old, with the first tooth typically appearing around 6 months. However, some babies begin as early as 3 months or as late as 12 months, and both are completely normal. The key is knowing what signs to look for and having a toolkit of safe, effective remedies ready.

Understanding the Teething Timeline

The American Academy of Pediatrics notes that baby teeth usually follow a predictable pattern, even though timing varies widely between children.

Typical teething schedule:

• 4-7 months: Bottom front teeth (central incisors)
• 8-12 months: Top front teeth (central incisors)
• 9-16 months: Side front teeth (lateral incisors)
• 12-19 months: First molars
• 16-23 months: Canine teeth
• 20-33 months: Second molars

By age 3, most children have all 20 baby teeth. But remember—these are averages. Some babies get their first tooth at 3 months, others wait until their first birthday. Both scenarios are normal and don't indicate any developmental issues.

Early Signs Your Baby Is Teething

Teething symptoms typically start 2-3 days before a tooth breaks through the gum and continue for a few days after. Here's what to watch for:

Physical signs:

• Increased drooling (often the first sign)
• Red, swollen, or tender gums
• Wanting to chew on everything
• Slightly raised temperature (under 101°F)
• Changes in eating or sleeping patterns
• Pulling at ears on the same side as emerging teeth

Behavioral changes:

• Increased fussiness, especially at night
• More clingy than usual
• Disrupted sleep patterns
• Less interest in food or bottle

The CDC emphasizes that while teething can cause mild discomfort, it shouldn't cause high fever, diarrhea, or significant illness. If your baby has a fever over 101°F or seems genuinely unwell, contact your pediatrician—something else might be going on.

Safe and Effective Teething Remedies

When your baby's gums are sore, you want relief that's both safe and actually works. Here are evidence-based approaches that pediatricians recommend:

Cold Therapy

Cold numbs pain and reduces inflammation. Try these options:

• Wet washcloths placed in the freezer for 15-30 minutes
• Chilled (not frozen) teething rings
• Cold fruit in a mesh feeder for babies 6+ months
• Chilled pacifiers

Avoid anything that's completely frozen, as it can damage tender gums.

Gentle Pressure and Massage

Counterpressure can ease the discomfort of teeth pushing through gums:

• Gently rub your baby's gums with a clean finger
• Let them chew on your knuckle (wash hands first)
• Offer firm teething toys made of safe materials
• Try a clean, damp washcloth for them to gnaw on

Foods for Teething (6+ Months)

Once your baby has started solids, certain foods can provide natural relief:

• Chilled cucumber spears (supervised)
• Cold watermelon or cantaloupe in mesh feeders
• Slightly frozen breast milk or formula in ice cube trays (then transferred to mesh feeders)
• Toast strips or unsalted crackers for gnawing

Always supervise eating and ensure pieces are large enough that they won't become choking hazards.

Over-the-Counter Pain Relief

For significant discomfort, the American Academy of Pediatrics says infant acetaminophen or ibuprofen can help:

• Acetaminophen: Safe for babies 2+ months (follow weight-based dosing)
• Ibuprofen: Only for babies 6+ months or older
• Always consult your pediatrician for proper dosing
• Don't exceed recommended doses or frequency

What to Avoid: Unsafe Teething Remedies

Some popular teething remedies can actually be dangerous. The FDA and pediatricians warn against:

Teething gels and tablets: Many contain benzocaine, which can cause a rare but serious condition called methemoglobinemia in babies under 2.

Amber teething necklaces: These pose choking and strangulation risks with no proven benefits.

Frozen teething rings: Rock-hard frozen items can damage gums and teeth.

Homeopathic teething tablets: The FDA has warned that some contain inconsistent amounts of belladonna, a toxic substance.

Adult pain medications: Never give aspirin, adult pain relievers, or medications not specifically approved for infants.

When to Call Your Pediatrician

While teething is normal, some symptoms warrant professional attention:

• Fever over 101°F (38.3°C)
• Signs of infection (pus around gums, persistent high fever)
• Refusal to eat or drink for more than a day
• Severe, inconsolable crying
• Symptoms that seem too intense for teething alone
• No teeth by 18 months

Trust your instincts. You know your baby best, and if something feels off, it's always okay to call your healthcare provider.

Making Nighttime More Manageable

Teething pain often feels worse at night when there are fewer distractions. Here's how to help everyone get more sleep:

• Give pain medication 30 minutes before bedtime if needed
• Stick to your regular bedtime routine for comfort
• Offer extra nursing or bottles for comfort
• Keep teething toys accessible in the crib
• Consider temporarily bringing baby closer to your room for easier nighttime comfort

Remember that sleep disruption during teething is temporary. Most intense discomfort lasts just a few days per tooth.

The Bottom Line

Teething typically begins between 4-7 months, but the range of normal is much wider. Look for increased drooling, gum changes, and the urge to chew as early signs. Safe remedies include cold therapy, gentle pressure, appropriate foods for older babies, and occasional pain medication when needed.

Avoid teething gels, amber necklaces, and anything completely frozen. Most importantly, remember that teething is a phase—uncomfortable for everyone involved, but temporary.

Frequently Asked Questions

How long does teething last for each tooth?

Teething symptoms typically last 2-3 days before the tooth breaks through the gum and continue for another few days afterward. The entire process for one tooth usually takes about a week, though this varies by baby and tooth type.

Can teething cause fever and diarrhea?

Teething may cause a slight temperature elevation (under 101°F), but it shouldn't cause high fever, diarrhea, or vomiting. According to the CDC, these symptoms indicate illness rather than teething and warrant a call to your pediatrician.

What if my baby hasn't started teething by 12 months?

Late teething is usually normal and often runs in families. Some babies don't get their first tooth until 15-18 months. However, if there are no teeth by 18 months, consult your pediatrician to rule out any underlying issues.

Is it normal for teeth to come in crooked or out of order?

Yes, baby teeth often appear crooked initially and may come in a different order than the typical pattern. They usually straighten out as more teeth emerge and as your child's jaw grows. Permanent teeth are a separate matter and will be evaluated by a dentist later.

How should I clean my baby's new teeth?

Start cleaning as soon as the first tooth appears. Use a soft-bristled infant toothbrush or clean, damp washcloth. The American Dental Association recommends using a rice grain-sized amount of fluoride toothpaste for children under 3, increasing to pea-sized for ages 3-6.
