What Is Teething
Teething is the natural process when a baby’s first teeth begin to come through the gums. This stage often starts between 4 and 7 months of age, but it can begin earlier or later depending on the child. Each baby grows at their own pace, so there is no exact time for when teething must start.
Before teeth appear, they grow under the gums and slowly move upward. As they push against the gum tissue, they create pressure that can cause mild discomfort. This is why babies may seem more fussy or want to chew on things more often.
Teething is not an illness. It is a normal part of development that every baby goes through. While it may cause some discomfort, it is usually mild and temporary.

Does Teething Cause Fever
One of the most common concerns parents have is the question does teething cause fever
Medical experts give a clear answer based on research and experience. Teething does not cause a true fever. While a baby may feel slightly warmer than usual, this small increase in temperature stays below the level of a real fever.
A fever is when body temperature reaches 100.4°F 38°C or higher. This is a sign that the body is fighting an infection. If your baby has a high temperature, it is important not to assume it is from teething.
Instead parents should consider other causes such as viral or bacterial illness and take proper action to protect their baby’s health. You can also learn more about oral health care through your dental provider to better understand early dental needs.
Teething Temperature vs Fever
| Condition | Temperature Range | Meaning |
|---|---|---|
| Normal | 97.7–98.6°F | Healthy body |
| Slight rise | 98.7–100.3°F | May happen during teething |
| Fever | 100.4°F or higher | Likely illness |
