What are Wisdom Teeth? When do They Appear?

The term wisdom tooth refers to the last molar tooth (among the three) to erupt in the jaw. These teeth emerge in the oral cavity at an age of around 17 to 25 years. They are commonly known as Wisdom Teeth because they tend to appear in the mouth at an age when the individuals grow up or become wiser. Some people get their wisdom tooth even after 25 years of age. After 30 years, their eruption is very unlikely.

For some people, these teeth prove to be a blessing (helps to chew) but in other cases they may be problematic for surrounding molar teeth and soft tissues. This depends on whether they are erupting in a correct direction or slightly tilting. They are mostly misaligned; either slanted towards or away from the second molar tooth, or inward (towards the tongue) or outward (towards the cheeks). Improper positioning of a wisdom tooth causes problems such as crowding, nerve injury, impaction or harm to adjacent teeth.

Functions of a Wisdom Tooth:

Our predecessors were the one to be the most facilitated by the third group of molars, thus aiding in the digestion process. On the other hand, the food that we prepare today is more refined and easily digested. This has dismissed the use of third molars.

Time Required for Complete Healing?

It takes several weeks to months for a socket to heal completely. Most of the healing process occurs within the first 2-3 weeks of extraction during which strict care is to taken. After this period, the patient should start feeling comfortable and this is all that is required.

Common Treatment Options for Wisdom Teeth?

The only treatment option for a problematic wisdom tooth is extraction. Firstly, because it doesn’t serve any important masticatory or aesthetic function. Secondly, because it is located far away from the mouth opening (since it is the last tooth in the jaw) which makes it difficult for accessibility and visibility.
