Quick Answer
Teething is when a baby's primary teeth emerge through the gums, often starting around 4 to 7 months per AAP guidance—though timing varies. Common signs include drooling, gum swelling, fussiness, and chewing on firm objects. Fever above 101°F (38.3°C) is usually not from teething alone. AAP guidance warns against benzocaine gels, homeopathic teething tablets, and amber necklaces. Brush new teeth with a rice-grain smear of fluoride toothpaste and schedule a first dental visit by age 1. WHO oral health guidance supports early prevention because decay can start with the first tooth.
What Parents Need to Know
Many babies explore the world with their mouths from about 3 months, but the first tooth often appears closer to 6 months. Order varies—some get bottom front teeth first, others top front teeth.
Teething is uncomfortable for some babies and barely noticeable for others. Heredity influences timing, so a late first tooth does not automatically mean something is wrong.
Evidence-Based Guidance
AAP teething guidance for 4 to 7 months explains:
- Central incisors (top or bottom front teeth) usually appear first, followed by opposite front teeth, then molars and canines
- Timing varies widely—some babies have no teeth by their first birthday
- Mild irritability, drooling, and chewing urges are common
- Gum massage with a clean finger or firm rubber teething ring can soothe discomfort
- Frozen teethers can become too hard and cause harm—use firm rubber instead
AAP first-tooth guidance adds:
- Most babies get teeth between 6 and 12 months, though some earlier or later
- Avoid benzocaine teething gels, homeopathic teething tablets, and amber necklaces because of toxicity, inconsistent ingredients, and choking risks
- Brush twice daily with a smear of fluoride toothpaste the size of a grain of rice once teeth appear
- Never let baby sleep with a bottle—pooled milk raises cavity risk
- First dental visit should happen within six months of the first tooth or by 12 months
WHO oral health guidance notes:
- Oral diseases are among the most common health conditions globally
- Most oral disease is preventable with hygiene, diet, and early care
- Primary teeth matter for chewing, speech, and holding space for adult teeth
- Professional care and fluoride support healthy development when used appropriately
- Early habits reduce lifelong dental burden
Practical Steps
- Offer a clean finger or firm rubber teether for gum massage—avoid frozen rings that turn rock-hard.
- Wipe gums twice daily with a soft cloth even before teeth appear.
- Brush new teeth with a rice-grain fluoride smear and a soft infant toothbrush.
- Schedule the first dental visit by the first birthday.
- Check temperature—call your pediatric clinician if fever exceeds 101°F (38.3°C) or baby seems very ill.
- Skip unproven products like amber necklaces and homeopathic teething tablets.
- Log symptoms so you can tell teething fussiness from illness patterns.
How MomAI Agent Helps
MomAI Agent on momaiagent.com helps you log drooling, fussiness, soothing methods, and each tooth's arrival date beside AAP and WHO oral health guidance so well-child visits start with clear notes. Mom AI Agent supports teething tracking—it does not diagnose fever, infections, or dental disease.
Safety Considerations
- Never tie anything around your baby's neck, including amber teething necklaces.
- Do not use benzocaine gels or homeopathic teething tablets marketed for infants.
- Avoid frozen teethers that can injure gums or break teeth later on.
- Do not attribute high fever or lethargy to teething—seek medical evaluation.
- Supervise chewing on teethers to prevent choking on broken pieces.
When to Contact a Clinician
Contact your pediatric clinician if:
- Fever is above 101°F (38.3°C) or baby seems unusually ill
- No teeth by 18 months—discuss at a routine visit
- Gums are bleeding heavily or you see a bluish cyst that worries you
- Baby refuses to drink or shows signs of dehydration
- Rash, diarrhea, or ear pulling accompanies fussiness and may suggest illness beyond teething
- You have questions about fluoride supplements or toothpaste use
The Bottom Line
Teething brings new teeth and temporary discomfort for many babies around 4 to 7 months, with wide normal variation. AAP guidance supports gentle gum massage, firm teethers, early brushing, and timely dental visits while avoiding risky gels and necklaces. WHO guidance reinforces that oral health starts early. Most teething fussiness passes as each tooth emerges.

FAQ
Q: What is teething?
A: Teething is the process when a baby's primary teeth push through the gums. AAP guidance explains that babies often start teething around 4 to 7 months, though some have no teeth by their first birthday and that timing can be normal.
Q: What are common teething signs?
A: AAP guidance lists mild irritability, increased drooling, desire to chew on firm objects, and swollen tender gums. A slight temperature rise may occur, but fever above 101°F (38.3°C) is usually not from teething alone and should be evaluated.
Q: What teething products should I avoid?
A: AAP guidance warns against teething gels with benzocaine, homeopathic teething tablets, and amber teething necklaces because of rare toxicity, inconsistent ingredients, and choking or strangulation risks. Firm rubber teething rings are safer than frozen teethers that become too hard.
Q: When should my baby see a dentist?
A: AAP guidance recommends a first dental visit within six months after the first tooth erupts or by 12 months of age, whichever comes first. WHO oral health guidance also supports early professional care to prevent decay.
Q: How can MomAI Agent help with teething?
A: MomAI Agent on momaiagent.com lets you log drooling, fussiness, gum massage, and the date each tooth appears beside AAP and WHO oral health guidance for well-child visits. Mom AI Agent supports symptom tracking—it does not diagnose fever causes or dental problems.
