Most 8-month-olds have between zero and four teeth, with two being the most common number. The two bottom front teeth typically appear first, usually between 6 and 10 months, followed by the two upper front teeth between 8 and 12 months. If your baby has no teeth yet at 8 months, that’s still well within the normal range.
What’s Typical at 8 Months
A commonly used rule of thumb is that for every six months of life, roughly four teeth will erupt. By that math, an 8-month-old might have around two to four teeth. In practice, the range is wider. Some babies cut their first tooth at 4 months, while others don’t see one until after their first birthday. Both extremes are normal.
The lower central incisors, the two small teeth at the very bottom center of the mouth, are almost always the first to break through. Their eruption window runs from about 6 to 10 months. At 8 months, many babies have these two and are working on the upper central incisors, which typically emerge between 8 and 12 months. After those four front teeth arrive, the upper lateral incisors (the teeth flanking the top front pair) usually follow between 9 and 13 months, with the lower lateral incisors coming in between 10 and 16 months.
Why Some Babies Get Teeth Later
Genetics is the biggest factor in teething timing. If you or your partner were late teethers, your baby is more likely to be one too. Premature birth can also shift the timeline, since tooth development follows gestational age more closely than birth date.
Nutrition plays a supporting role. Calcium and phosphorus are the primary minerals that form tooth enamel, and vitamin D helps the body absorb both of them. Babies who are breastfed, formula-fed, or eating age-appropriate solids generally get enough of these nutrients without supplementation, though your pediatrician may recommend vitamin D drops for breastfed infants.
A baby with no teeth at 8 months doesn’t need any special evaluation. Most pediatric dentists consider delayed eruption worth looking into only if no teeth have appeared by around 18 months.
Signs a Tooth Is Coming
You’ll often notice the signs before you see the tooth. Increased drooling, chewing on fingers or toys, and mild fussiness are the classic indicators. Some babies develop slightly swollen or reddened gums right where the tooth is pushing through. Sleep disruptions and mild irritability around mealtimes are common too, especially when the larger upper front teeth are on their way.
Teething does not cause high fevers, diarrhea, or rashes. A very slight rise in temperature (below 100.4°F) can happen on the day a tooth breaks through, but anything higher is likely from an unrelated illness that just happens to coincide with the teething window.
Safe Ways to Ease Teething Pain
The simplest and most effective relief is pressure on the gums. Rubbing your baby’s gums with a clean finger or a piece of wet gauze for about two minutes can noticeably reduce discomfort, and you can do it as often as needed. Chilled (not frozen) teething rings, pacifiers, or wet washcloths from the refrigerator also work well. If you use a teething ring, choose one filled with distilled water rather than gel, in case your baby’s new teeth puncture it.
For babies who are especially uncomfortable, infant-appropriate pain relievers like acetaminophen or ibuprofen can help, but limit use to one or two days at a time.
Avoid frozen items like ice or frozen pops, which can cause frostbite on delicate gum tissue. And skip hard foods that pose a choking risk.
Products to Avoid
The FDA has issued direct warnings against using teething gels or creams that contain benzocaine or lidocaine on infants. These numbing agents, found in products like Orajel and Anbesol, can cause a dangerous condition called methemoglobinemia, which severely reduces the blood’s ability to carry oxygen. The FDA also warns against homeopathic teething tablets, some of which have been found to contain inconsistent and potentially harmful amounts of belladonna, an ingredient that can trigger seizures and breathing problems in small children.
Caring for Those First Teeth
Even before any teeth appear, the American Academy of Pediatric Dentistry recommends cleaning your baby’s gums with a soft infant toothbrush or damp cloth. Once that first tooth breaks through, switch to brushing twice a day with a soft-bristled toothbrush designed for infants and a tiny smear of fluoride toothpaste, roughly the size of a grain of rice. That small amount provides cavity protection without posing a risk if swallowed.
Brushing at bedtime is especially important. Milk or formula that pools around new teeth overnight can promote early decay, sometimes called “bottle mouth.” If your baby falls asleep with a bottle, try to gently wipe the teeth and gums with a damp cloth before putting them down.
The First Dental Visit
The American Academy of Pediatric Dentistry, the American Dental Association, and the American Academy of Pediatrics all recommend scheduling a baby’s first dental visit by age one or within six months of the first tooth appearing, whichever comes first. For an 8-month-old who already has a tooth or two, that means a visit in the next few months is a good idea. These early appointments are brief and low-key. The dentist checks for proper development, looks at how the teeth are coming in, and gives you personalized guidance on cleaning and fluoride use. Starting early also helps your child get comfortable with dental visits before they’re old enough to feel anxious about them.
