Wisdom Tooth Decay – Should it be removed or filled?

Theo dõi Gangwhoo trên

Wisdom tooth decay is quite common nowadays. Wisdom tooth decay is when it grows impacted or at the back of the gums, making it difficult to clean your teeth every day. In addition, because wisdom teeth are located next to important chewing teeth on the jaw, food can easily get stuck in this position, thereby causing tooth decay.


1. Great consumption of starchy food and sweets

Sugar and starch are the food that creates an ideal environment for the bacteria to reside and wreak havoc on our teeth. If you do not clean your teeth thoroughly after eating, microscopic food debris can stick to the surface of the teeth. Bacteria will “consume” this food debris and then release acid. It is this acid that will cause damage to the tooth surface, creating tiny holes that are difficult to see with the naked eye. Over time, these tiny holes will damage the outer layer of enamel. It then reaches the inner dentin layer and gradually touches the pulp.

Tooth decay starts with small holes on the teeth’ surface because acids and bacteria can penetrate the enamel layer, affecting the dentin. Lots of people think that the micro dark holes on the teeth’ surface are not significantly big, so there is no need to visit the dentist. But in fact, there are lots of serious cases of tooth decay caused by tiny holes on the teeth’ surface. At that time, the cavity of the tooth pulp has been severely damaged, causing the tooth to weaken quickly and easily crumble.

3. Bad breath

Poor dental hygiene can cause wisdom tooth decay. Another sign of tooth decay is that the breath can be a little “smelly” without us even realizing it. In addition, when bacteria consume starch and sugar, they will release gases that create an unpleasant scent. Those who have wisdom tooth decay, they should brush their teeth and use mouthwash daily.
