No, babies don’t have to have fever when they are teething, but they may have the following symptoms (depending on individual babies):

Slight fever: the inflammation on the gum may cause slight fever, lower than 38.3oC. For safety’s sake, if the fever lasts three days, you will have to take the baby to a doctor.

Salivation: teething will stimulate the secretion of saliva.

Rashes on the chin or face: the rashes may be caused by allergy due to contacts with saliva for a long time. To avoid these rashes, you will need to constantly wipe away the saliva secreted. Also, when the baby is asleep, put a small towel underneath the face to absorb the saliva.

Slight cough: too much saliva may cause nausea and cough. It does not really matter so long as it is not flu or allergy. Sometimes, babies may try to attract attention by coughing; they may think that coughing is fun!

Nibbling: babies may tend to bite when they see people because, through this action, they are trying to release the pressure on the gum when they are teething.

Pain: inflammation is the only way that the soft gum deal with the out growing teeth, and it may cause sharp pain in some babies while some may not feel anything. The baby is particularly uncomfortable when they grow the first tooth and molar tooth.

Touchy: when the tip of the growing tooth gets closer to the surface of the gum, and inflammation is getting serious, the continual pain will make the baby get angry easily

Refusal to Eat: the babies who are growing teeth may be touchy and restless; they may feel like putting something in their mouths and act like very impatient. However, the sucking action may cause pain on their gum, leading them to lose interest in eating. Those babies who have started to take solid food may also refuse to eat; in this case, milk is essential to maintain their nutrition. If the refusal of food persists, you will have to take the baby to a doctor.

Diarrhea: some doctors think diarrhea is related to teeth growth, because the babies have swallowed too much saliva making feces soft. But some doctors disagree with this thinking. In any case, parents have to pay attention when their babies are suffering from diarrhea.

Sleeplessness: the growing of teeth occurs during both night and day, and they may not be able to sleep due to discomfort. If your baby wake up suddenly, don’t coax or feed him/her right away; wait and see if he/she will calm down by him-/herself.

Bleeding on the Gum: teething may sometimes cause bleeding on the gum, forming a bruised sarcoma. Most doctors suggest that we let it heal by itself. An iced pad may be used to speed up the recovery.

Touching the ear and cheek: the pain on the gum may be transmitted to ear and jaw through the nerve, especially when growing the molar tooth. Therefore, we may see the baby scratching his/her ear or touching his/her face.

Give the baby something to bite, such as a cold banana; it will be able to alleviate his/her pain.
