What is Hyperdontia: 7 Effective Treatments for Excess Teeth

If you or your child seem to have more teeth than everyone else, you are not imagining it. Some people are simply born with extra teeth, and that is exactly what hyperdontia means. In Ventura County and across our five clinic locations, our dentists see this condition regularly. The good news? In many cases, it can be treated simply and safely.

This guide will explain everything you need to know about hyperdontia in plain language, no dental degree required.

What is hyperdontia?

Most people grow 20 baby teeth as a child and 32 permanent (adult) teeth by the time they are adults. Hyperdontia is the term used when a person grows extra teeth beyond that normal number.

These extra teeth are called supernumerary teeth, which just means “more than needed.” They can show up anywhere in the mouth, but they appear most often in the upper front area. A person might have just one extra tooth or several.

You might also hear it called: supernumerary teeth, extra teeth, or accessory teeth. All of these terms refer to the same condition.

Types of hyperdontia

Not all extra teeth look the same. Here are the most common types:

• Mesiodens: The most common type. A small extra tooth that grows behind or between the two upper front teeth.
• Paramolar: An extra tooth that grows next to one of the back molars.
• Distomolar: An extra tooth that grows behind the last molar, further back in the mouth.
• Conical: Cone-shaped, like a small peg.
• Supplemental: Looks like a normal tooth but is just extra.
• Tuberculate: Barrel-shaped; this type often stays hidden under the gum and does not come out on its own.

Some extra teeth come through the gum (erupted), and others stay hidden inside the jawbone (impacted). Impacted supernumerary teeth are only visible on an X-ray.

Why does hyperdontia happen?

Researchers have not yet found one single cause for hyperdontia. What we do know is that it tends to be related to a mix of genetics and other developmental factors. In other words, some people are simply born with a tendency to grow extra teeth.

Hyperdontia is also seen more often in people who have certain health conditions, including:

• Gardner syndrome (a genetic condition that can also affect the skin and colon)
• Cleidocranial dysplasia (a condition that affects how bones develop)
• Cleft lip or palate
• Down syndrome
• Ehlers-Danlos syndrome

However, many people with extra teeth have none of these conditions at all. It can simply happen on its own. It is also more common in men than in women.

What does a patient see or feel? signs of hyperdontia

Many people with hyperdontia do not feel any pain or discomfort, especially if the extra teeth are hidden. In those cases, the only way to discover them is through a dental X-ray during a routine visit.

However, some patients do notice things like:

• A tooth or teeth that look different or seem to be in an unusual spot
• Crowded teeth or teeth that are crooked or pushed out of place
• A gap between the upper front teeth that will not close (called a diastema)
• A baby tooth that does not fall out on time, because an extra tooth is blocking the adult tooth underneath
• An adult tooth that never comes in, because a hidden extra tooth is blocking it
• Swollen or tender gums in a specific area
• Difficulty chewing or biting properly

If you or your child are experiencing any of these signs, it’s a good idea to schedule a dental visit at one of our Channel Islands Family Dental offices in Ventura, Oxnard, Newbury Park, Port Hueneme, or Santa Paula.

How is hyperdontia diagnosed?

Diagnosing hyperdontia is usually straightforward. Here is what to expect:

• Clinical exam: Your dentist will look carefully inside your mouth to see if any extra teeth are visible.
• Dental X-rays (panoramic or periapical): These are the most important tool for finding extra teeth, especially those that have not come through the gum yet. A panoramic X-ray gives a full picture of all your teeth and jawbone.
• CT scan: In more complex cases, a 3D CT scan may be recommended. This gives a very detailed picture and helps the dentist plan treatment precisely.

At Channel Islands Family Dental, we use modern digital X-ray technology at all our locations in Ventura, Oxnard, Newbury Park, Port Hueneme, and Santa Paula, to detect hyperdontia early and accurately.

How do we treat hyperdontia at our clinics?

Not every extra tooth needs to be removed right away. The treatment depends on whether the tooth is causing problems. Here is how our dentists approach it:

Monitoring (watch and wait)

If the extra tooth is small, not causing any pain, not blocking other teeth, and not creating hygiene problems, your dentist may recommend monitoring it over time with periodic X-rays.

This is common in children whose mouths are still developing.

Extraction (tooth removal)

This is the most common treatment. The extra tooth is removed surgically, usually under local anesthesia (a numbing injection). This procedure is routine in our offices and most patients do very well.

Extraction is typically recommended when the extra tooth is:

• Blocking an adult tooth from coming in normally
• Causing crowding or shifting of other teeth
• Making it hard to brush and floss properly (which raises the risk of decay)
• Causing gum swelling or pain
• Affecting the patient’s appearance or self-confidence

Orthodontic treatment

After an extra tooth is removed, the remaining teeth may need to be guided into the correct position. Your dentist may refer you to an orthodontist for braces or clear aligners to straighten things out.

Pain management

If an extra tooth is causing mild discomfort, your dentist may suggest over-the-counter pain relievers such as ibuprofen as a short-term measure while a treatment plan is arranged.

Our dentists at Channel Islands Family Dental in Ventura County evaluate every case individually. The right treatment for you or your child depends on the type, location, and impact of the extra tooth.
