What are impacted teeth?
When one or more teeth fails to grow in the correct position and is therefore held below the normal gum line, it is called an impaction. This can be complete, such as completely unerrupted (buried) third molars (wisdom teeth) or partial when just part of the tooth is visible in the mouth.
For best function and appearance the teeth should grow in a healthy alignment. When one or more teeth is impacted, this can affect the function of that tooth but also the function and appearance of other teeth.
If impacted teeth are not treated, some can lead to medium and long-term problems such as decay, infection, gum disease and dental cysts – but these can all be watched out for by dentists.
Normally, every adult has two canine teeth in each upper and lower jaw. They are the ‘pointier’ eye teeth (‘fangs’ in animals) that are in line with the corner of your mouth.
Children also have the same number of canine teeth but these will normally be shed when the adult (permanent) teeth replace them.
Canine teeth are more important than some other teeth for the correct function of the teeth and also for appearance. This is why dentists and orthodontists like to correct their position if possible.
What can go wrong with canine teeth?
Sometimes, because of the way teeth grow in the jaws and gums, one or both canine teeth develop in the wrong position for normal appearance or function. For example, they might erupt in the wrong position or not at all.
Dentists and orthodontists usually detect a problem with the canine teeth in children around the ages of 10-14 years, which is a time when they will recommend treatment.
The treatment options for impacted or misplaced canines will depend on the type and severity and the alignment of other teeth. Your dentist, orthodontist and/or oral and maxillofacial surgeon will explain the options to you, which can include surgery.
