The final and third set of molars are the wisdom teeth. If they are properly aligned and healthy they can be an asset, if they are impacted or crooked they will most probably have to be extracted. Wisdom Teeth Extractions – Dental Care can advise you on what is best for your situation.
When wisdom teeth grow horizontally they can damage adjacent teeth, the jawbone, or the nerves and will have to be removed. They can trap plaque and cause decay. If they are entrapped in the soft tissue they can allow bacteria to grow and cause infection, this is known as an impacted tooth which can be very painful. Brushing is difficult and gum disease is likely to develop with these teeth.

The teeth are made up of three layers which include enamel, dentin, and pulp. Teeth are important for speech and chewing and are the hardest substance in our bodies. Enamel is the outer white part of the tooth. Dentin in the underlayer made up of living cells and pulp is the soft inner structure made up of nerves and blood vessels.
Your dentist will take x-rays of your teeth periodically to see what is going on, if your wisdom teeth need attention he or she will advise you accordingly. Misaligned or horizontal teeth may need to be extracted before they cause problems. Doing this will prevent more complex and painful extractions at a later time. It is easier to remove wisdom teeth in younger people when the bone is less dense and not fully developed. When it is done on older people they take longer to heal.
Wisdom teeth are easily extracted, like any other teeth, if they fully erupt. If not your dentist will let you know what the plan is in the pre-extraction exam. If they are embedded in the gums and jawbone you will need to have some of the bone removed as well. They will probably be removed in sections to minimize the amount of bone that will be lost. You will be given a local and a sedative during the procedure and you should not drive yourself home.
