An impacted tooth is one that is unable to come up through the gum in the normal manner. It may have twisted roots that have tangled around the roots of other teeth or become attached to the jawbone. It may have moved or developed into a horizontal position and have one end caught underneath the roots of the adjoining tooth. Or the space for it to emerge is simply not big enough to accommodate the size of the tooth.

An impacted tooth can cause a great deal of pain as it tries to emerge and then goes back again. In many cases, this process lasts for years if not attended to. Many wisdom teeth - or third molars - are impacted and unable to erupt. Pain at the back of the jaw and gum is often a sign of an impacted tooth.

In some cases, the tooth will come just partway through and then these small edges trap food particles that are difficult to remove. This will quickly lead to decay in both the impacted tooth and its nearest neighbour. Dentists recommend removal of wisdom teeth and in some cases must take them out in pieces. But that's better than leaving them their to cause their many problems.
