Teething can cause a lot of trouble for babies. It’s a natural process but it’s still very painful. It can begin when your baby is 3-month-old, it usually happens between 4 and 7 months.
According to kidshealth.org:
The first teeth to appear usually are the two bottom front teeth, also known as the central incisors. They’re usually followed 4 to 8 weeks later by the four front upper teeth (central and lateral incisors). About a month later, the lower lateral incisors (the two teeth flanking the bottom front teeth) will appear.
Next to break through are the first molars (the back teeth used for grinding food), then finally the eyeteeth (the pointy teeth in the upper jaw). Most kids have all 20 of their primary teeth by their third birthday. (If your child experiences significant delay, speak to your doctor.)
What are the teething symptoms:
The level of pain that a baby can handle will be different for each child. Some may be a lot fussier than others while they are teething. The soreness and swelling of the gums before a tooth comes through is the cause for the pain and fussiness a baby experiences during this change. These symptoms usually begin about three to five days before the tooth shows, and they disappear as soon as the tooth breaks the skin. Some babies are not even bothered by teething.
