toddlers and small children are brought to the dental offices for consultation visits as soon as milk teeth appear in their mouth. However, lifestyle modifications and improved dietary habits are needed. These days, Children do not like to eat hard foods. Increased intake of fast foods, soft diet and cola drinks causes decreased stimulation of jaw bone growth during early life when jaw development is underway. Restricted jaw growth is the major reason for impacted third molars/wisdom molars


What are third molars? Why these third molars are known as wisdom teeth?


Third molars or wisdom molars usually remain hidden within the gums or socket bone due to limited space or hindrance in their path of eruption. These are most commonly impacted teeth followed by second premolars and upper lateral incisors. Wisdom teeth are usually absent in a large number of individuals. Sometimes, wisdom teeth make their path within the small sized jaw bones or limited which results in their tilting, drifting, rotation. These tilted, drifted and rotated wisdom teeth badly affect adjacent teeth, jaw bone and nerves crossing near their roots and crowns. Furthermore, these can act as spaces accumulation of food debris which can result in infections, gum diseases and tooth decay in the future. Is wisdom teeth removal necessary always? No.

These teeth normally erupt around 17-25 years of age (late teenage years and early twenties). This age range is associated with the development of intelligence and learning in young ones. This is the reason why these third molars are called wisdom teeth.

wisdom teeth removal necessary


When jaw bone growth becomes restricted, it results in late eruption of teeth and this decreased size of jaws cannot accommodate all teeth within the mouth. Third molar teeth are located in the end of your mouth do not find enough space to erupt and remain within the gums and jaw bones. Little or no space does not allow these relatively large sized teeth to erupt through the jaw bone and gums. The diet has softened and people do not eat foods that are as hard. As a result Jaws are smaller and teeth do not have as much room to fit.


Why is it necessary to remove wisdom teeth from the mouth in majority of cases?


Abnormally tilted, drifted and rotated wisdom teeth become the reason for the occurrence of food impaction, infection and swelling of gum tissues surrounding and covering these teeth. Food particles cannot be easily cleaned from these narrow spaces and pockets around the wisdom molars leading to development of reddish, swollen and infected soft tissues which become extremely painful especially when patient tries to open wide. Normal tooth brushing and mouth rinsing becomes less beneficial when the problem becomes severe.

Severe pain, infection, fevers and reduced mouth opening develops in severe cases. You will be unable to eat, talk and perform your daily activities. Do all wisdom teeth need to be removed? Not always.

Novel treatments such as PRF wisdom teeth surgery, help accelerate bone healing and reduce swelling and pain after wisdom teeth removal.

Removal of these affected teeth becomes essential for the prevention of infection spread. Exposure and removal of surrounding jaw bone and gums may be needed. American Dental Association recommends complete and comprehensive consultation regarding the status of wisdom teeth buds in infants or around 16-19 years of age. Their early removal following preventive approach can save future complications.
