Babies begin to cut teeth at around four to seven months old in most cases, with some late developers waiting until one year or later. Some babies, however, will experience the first tooth breakthrough or signs of teething even earlier. A three-month-old with teething symptoms is not uncommon, and the physical signs of this occurrence are fairly easy to spot if you know what to look for.
One of the first things a parent will notice about a teething baby is excessive drooling. A three-month-old baby will often begin drooling to the extent that the baby requires a fresh bib quite often. This is very likely a sign of teething. Even if the tooth buds are not visible yet, the teeth are approaching the surface and pushing upward with considerable force. This upward movement stimulates the production of saliva, causing the perfectly normal drooling problem, according to The Labor of Love.
When the developed teeth begin pushing against the surface of the gums, trying to cut through them, it is not surprising that it causes trauma to the gum line. Irritated, red and swollen gums are a normal part of this process. Parents may also notice white dots on the gums or small openings where teeth will appear in coming days, according to Parent Time.
Before the breakthrough of the new tooth, painful red spots that swell will likely appear. This swelling and irritation will cause a considerable amount of discomfort to the baby. Topical medicines to dull the pain are available from drug stores. Make sure the medicines are safe for baby use before application. Teething rings also provide comfort for irritated gums.
You can't blame the baby for being fussy at this point in his life. A sudden increase in fussy behavior may be a sign of teething. The pressure on the gums and the irritated area where the tooth is about to break through or has already broken through will likely cause some crying and irritable behavior.
Another side effect of the pain and irritation associated with teething is the inability to sleep. A combination of the above symptoms and a problem with getting to sleep or staying asleep is very likely a sign of teething.
Just like anyone else, even a dull pain can be enough to put extra stress on the baby's mind and body. This can lead to sleepless nights for baby, mom and dad.
Teething may be the reason the three month old refuses to eat, according to Baby Center. When the gums are especially irritated and painful, the chewing motion may cause discomfort. The spoon going into the mouth may also hurt when it touches the affected area.
Low Grade Fever
Any fever in a small child is cause for concern. However, a low-grade fever may simply be another sign of teething. Sometimes, the gum irritation can trigger a mild fever. Keep an eye on the baby's condition when a fever is present to make sure it isn't something more serious.
