Tooth extraction is the removal of a tooth from its socket in the bone.
If a tooth has been broken or damaged by decay, your dentist will try to fix it with a filling, crown or other treatment. Sometimes though, there has been too much damage to the tooth that it cannot be repaired. In this case, the tooth will need to be extracted. A very loose tooth also will require extraction if it can't be saved, even with bone replacement surgery (bone graft). Wisdom Tooth Surgery
Adults can have up to four wisdom teeth, two in the upper and lower jaw respectively. The wisdom teeth are the last to erupt into the oral cavity. Sometimes the wisdom teeth do not erupt in the correct orientation due to space constraints.
In such cases, it is recommended to have the impacted tooth surgically removed. This prevents tooth decay on both the wisdom tooth and the tooth in front of it, which often occurs as a result of food trapping in the area.
