Many teens and adults have wisdom teeth emerge without any discomfort or pain, and in these cases it would be inappropriate to remove them. However, it is usually during the emergence of the teeth that it becomes apparent there is a problem.
Our modern diet has resulted in a larger dental arch and there is often just no room for the wisdom teeth to emerge. This can cause extreme pain in the mouth and head and push the other teeth out of alignment. It is also common for wisdom teeth to begin emerging at an angle so that they cannot emerge fully as the other molars are blocking the way.
Wisdom teeth are more susceptible to decay and infection as they are right at the back of the mouth and are often difficult to reach for regular daily dental care. Wisdom teeth can also become broken.
In all of these instances your dentist will examine the tooth, and most likely take x-rays, to determine whether an extraction is necessary. X-rays will also show whether a standard or surgical extraction is required.
