Wisdom teeth are rear molars that erupt last, usually around the late teens or early 20s. There are normally two wisdom teeth in the upper jaw and two in the lower jaw.
Wisdom teeth can cause various dental problems. Sometimes it will be recommended that problematic and painful wisdom teeth be removed.
Common problems of wisdom teeth
Wisdom teeth infection – In some cases, there may not be enough room in the jaw for wisdom teeth. This can make brushing and flossing these teeth very difficult. Food and bacteria will build up between the wisdom tooth and its neighbouring molar, therefore decay and gum infections are more likely.
The symptoms of an infection caused by a wisdom tooth include:
reddened, inflamed gum alongside the wisdom tooth
sore lymph glands under the jaw
difficulty swallowing or opening the mouth
