There is no fixed time period for wisdom teeth to erupt and form; most people’s wisdom teeth will form around the age of 16 and may be in the growth phase until the age of 35. Normally, there are four wisdom teeth in the back of the human mouth, two at the top and two at the bottom, which begin to erupt and grow between the ages of 16 and 35. Some individuals may also have missing wisdom teeth due to physical variability, but this does not affect their normal oral systemic function. When wisdom teeth are in the eruption or growth phase, they may be placed horizontally, tilted toward or away from the second molars or tilted inward or outward. However, as the wisdom teeth grow, their improper alignment can crowd or damage other tissues such as adjacent teeth, jawbone, and nerves, resulting in pain, swelling, jaw stiffness, and other adverse symptomatic reactions, and in severe cases, even evolve into pericoronitis or other oral systemic diseases. In addition, some individuals are at increased risk of wisdom tooth decay due to inadequate oral cleaning. Once you feel toothache, swelling and other uncomfortable symptoms during the eruption and growth of wisdom teeth, it is recommended to go to the dentistry department of the hospital for examination as soon as possible to rule out the possibility of lesions and to clarify the cause of the disease for targeted treatment.
