Hyperdontia is an oral condition in which a person has supernumerary teeth, which means that they have more teeth than the standard number of 20 primary (baby teeth) or 32 permanent teeth. Although excess dentition doesn’t always cause problems, it’s a good idea to talk with your Westmount dentist about potential issues and the best ways to keep your teeth and mouth healthy.
What Causes Hyperdontia?
The cause of hyperdontia is not entirely clear, but it is believed that genetic factors may be involved. Risk factors for hyperdontia include conditions such as Ehler-Danlos syndrome, Down’s syndrome Gardner syndrome, and cleft lip and cleft palate. It is more common in males than females.
Also known as baby teeth, your primary teeth are the first set of teeth that erupt, usually by the age of three. Primary teeth are commonly shed by the time you’re about 12, and permanent teeth erupt to take the place of primary teeth. Typically, permanent teeth are fully erupted between 16 and 18. A person with hyperdontia develops more than 20 primary teeth or more than 32 permanent teeth. These additional teeth are called supernumerary teeth. Hyperdontia in primary dentition typically causes more problems and must be monitored to see if future treatment such as orthodontia is needed. it If you or your child develops has supernumerary teeth, it’s important to visit your dentist for a thorough exam and x-rays to detect and evaluate supernumerary teeth as soon as possible.
Dental Problems Caused by Hyperdontia
Excess dentition can cause an array of cosmetic and functional issues, including:
- Delayed eruption of adjacent teeth
- Impacted teeth
- Overcrowding of teeth
- Chewing issues
- Fusing with permanent teeth
- Growth of cysts or tumors
Treatment for Hyperdontia
Extraction of supernumerary teeth and orthodontic treatment can help prevent and correct problems caused by hyperdontia. When a child is very young, it can be difficult to determine how primary supernumerary teeth will affect permanent teeth, alignment, and bite, so many Westmount dentists take a “wait and see” approach when treating children. When hyperdontia involves permanent teeth, it is usually easier to apply solutions such as extraction and orthodontic treatment.
Visiting your Montreal dental clinic at least twice a year for regular checkups and professional cleanings can help to ensure that your oral health isn’t being harmed by excess dentition. Make sure to practice a good oral hygiene routine, which includes flossing, rinsing and brushing twice a day with fluoride toothpaste. This can be especially helpful if you have crowded or crooked teeth, as bacteria and plaque can easily accumulate in hard-to-reach places between them.
