Teething and Fever
Does teething cause fever? Most experts will tell you that teething does not cause fever and definitely does not cause a high fever. It may cause a low grade fever though, especially on the day that the tooth actually erupts, but when it doubt, don't blame your child's fever on teething, especially since it could be a coincidence and your child could be teething and have another illness causing the fever.
In addition to a high fever, such as above 102 F, teething is not usually thought to cause diarrhea, a decreased appetite for liquids, other types of rashes, or a cough.
