How Long Does Teething Last? The 6 Stages of Teething

Your baby getting their first teeth is an exciting moment that parents love to talk about. It’s a tangible milestone in your child’s development that brings them into the world of textures and flavors. But if your child has just started teething, you might be wondering how long the process is going to be, especially if they seem uncomfortable or distressed by it. So how long does teething last, and what can you expect?

In this post, we’ll look at how the teething process occurs by dividing it into five stages sorted by age. Next, we’ll discuss why your child can seem upset and distressed while teething and offer some advice.

How The Teething Process Works

Your baby’s first teeth will cut through their gums as they emerge into the mouth. Naturally, it can be uncomfortable, even painful for them. Even before this emergence happens, the child can start to show symptoms and behaviors of teething.

Some of these symptoms include:

  • Drooling, sometimes causing a mild rash
  • Irritability or fussiness from time to time
  • Refusing to eat food
  • Swollen gums
  • Behaviors involving the mouth, such as biting, chewing on, or sucking objects
  • Rubbing the face or ears, particularly when molars are emerging
  • Inability to sleep, restlessness
  • Mild fever (less than 101 degrees)

However, if your baby’s experiencing coughing, rashes elsewhere on the body, rising fever, coughing, or diarrhea, these are not related to teething. They might suggest another illness or condition, and you should contact your pediatrician.

How they handle the teething process is entirely up to your baby’s temperament. Some children have no trouble at all, while some become very fussy and cranky. Knowing the timeline for teething is, therefore, important for you to know what to expect. Here are the five stages of teething.

How Long Does Teething Last?

Note that the ages given are average ages. Some children may have teeth come in much later, but the average child begins to teeth by around six months. Teeth might also emerge in pairs, which can make the process seem longer.

Stage 1 – Central Incisors

Between the ages of 6-12 months, you can expect your baby to get their very first teeth. These are often the lower and upper central incisors, which lie front and center in your baby’s mouth. The lower central incisors can erupt between 6-10 months, with the upper incisors coming in at 8-12 months.

Stage 2 – Lateral Incisors

Next to central incisors are the lateral incisors, which can come in at around 9-13 months. Both upper and lower incisors can erupt in this period, with the process completing at around 16 months.

Stage 3 – First Molars

The first molars are separated from the lateral incisors by canines, which will erupt later. They emerge at 13-19 months, and your baby may rub their cheeks and pull their ears due to the discomfort. This is normal, and your pediatrician can advise solutions to calm your child.

Stage 4 – Canines

The distinctive canines come in between 16-23 months in, and by the time your child is two years old, they’re almost done teething.

Stage 5 – Second Molars

The second molars are the last teeth to erupt, occurring between 25 and 31 months. By the age of three, the teething process should be complete. At this stage, your child should be able to tolerate the eruption of new teeth relatively well.
