When Do Babies Get Their First Tooth? It Depends on Genetics.

September 17, 2021

First Tooth or Baby teeth milestones are not as precise as other milestones for infants. Baby teeth are born at different ages. Some babies have one or more teeth. Sometimes, babies don’t get their first tooth until 12 months. Baby teeth can emerge between 4 and 10 month olds, with an average age of 6 months for most babies. While genetics are largely responsible for the time when teeth appear, timing can have serious consequences on infant health.

Dr. Kami Hoss is a UCLA School of Dentistry Board of Counselors member. She says that “if the teeth come in a couple of months early or late there are usually no concerns.” It can become a problem if the timing is not right. For example, early teething affects breastfeeding.

Hoss says this is a very important consideration because breastfeeding is so vital for your oral health. Breastmilk is good for your baby’s facial muscles and helps you avoid cavities.

Supernumerary teeth, or the presence of additional teeth, can also be detected in very early teeth. Hoss states, “I have seen anywhere from one to twelve extra teeth in children.” “An additional tooth that is not allowed in can cause regular teeth to become crowded or gum damage,” Hoss says.

Supernumerary teeth are treatable when caught early enough. You can have them removed easily. That is if your baby doesn’t suffer from any problems.

There could be several reasons why teeth may not emerge as expected. You would sometimes find a tooth stuck between two teeth. You would sometimes, miss a permanent tooth because of a delayed tooth. In both cases, x-rays will be required to diagnose the problem and determine possible treatment options. Sometimes, kids suffers from thrush usually before teeth emerge due to weak immune system. These phases make kids fussy and irritated.

Hoss encourages parents to be calm if they aren’t getting their first baby teeth in time. He says that there are families who get their teeth later than others. “If I see a child with teeth that are coming in late, I will usually ask when their siblings got them. It’s usually because their biological clock is slower.

In those cases, the biological clock may be slower. The same child may not reach all milestones in the same time span, even though they are walking to puberty. Parents should consider the developmental pace of each child when setting milestones.

Hoss points out that it is possible to manage baby dental health problems. However, it is crucial to catch the problem early enough to fix it.

Hoss states that the American Academy of Pediatric dentists recommends every child see a pediatric dentist within six months of their first birthday. “But I personally believe that after 25 years in practice, the latest parents should visit a pediatric dentist. I recommend that parents find a dentist for their baby during pregnancy.
