How Long Does Teething Last?
Average Timeline of Teething
Teething is supposed to start around six months of age, but for some babies, it can begin as early as three to four months or as late as after their first birthday. Most children finish teething by the time they are two to three years old, with a complete set of 20 baby (primary) teeth. Baby teeth usually come in a certain order, which is mostly the same for all children:
- Lower central incisors (the two front bottom teeth) usually erupt first, around 6 to 10 months old.
- Upper central incisors (the two front top teeth) usually appear next, around 8 to 12 months old.
- Lateral incisors (the teeth next to the front ones, both top and bottom) come in around 9 to 16 months old.
- First molars (the back teeth used for chewing) erupt next, between 13 and 19 months on the top, and 14 to 18 months on the bottom.
- Canines (also called cuspids) appear between 16 and 23 months of age.
- Second molars are the last to appear, usually between 23 and 33 months old.

Common Symptoms During Teething
Here are some signs that your child is going through the teething process:
- Drooling: Babies often drool a lot during teething. This can sometimes cause a rash on their face, chin, or chest due to skin irritation.
- Irritability and Fussiness: Babies may become crankier or cry more because their gums hurt as the teeth push through.
- Chewing and Biting: To ease the discomfort, babies may chew on their fingers, toys, or anything they can find. They might also rub their gums or cheeks.
- Sleep Problems: Teething can make it harder for babies to sleep well or stay asleep through the night.
- Swollen Gums: The gums where a tooth is coming in may look red, swollen, and feel sore.
- Other Signs: Some babies rub their cheeks or ears on the side where the tooth is coming in. They might also eat less for a short time.
When to Consult a Pediatric Dentist?
During teething, symptoms usually last only a few days for each tooth, starting a few days before the tooth comes in and ending a few days after. If the symptoms last much longer, it may be due to something other than teething. Signs that it might not be teething and your baby should see a doctor include:
- High Fever: A temperature over 38°C (100.4°F) is not common with teething and could mean your baby has an infection or illness.
- Extreme Fussiness: If your baby cries a lot and can’t be comforted, it may be more than just teething.
- Diarrhea, Vomiting, or Other Illness Symptoms: These are not caused by teething and should be checked by a doctor.
- Widespread Rash: Teething may cause a rash around the mouth or chin due to drooling, but a rash on other parts of the body could be a sign of something else.
- Not Eating or Drinking: If your baby refuses to eat or drink anything, including breastmilk or formula, it may be a sign of illness.
If your baby has any of these symptoms or the discomfort lasts too long without a tooth coming through, it’s best to see a pediatric dentist. They can check for any other problems and help your baby feel better.
