What Is an Impacted Tooth? Causes, Signs, and Treatment Options

What Is an Impacted Tooth?

An impacted tooth is a tooth that becomes trapped beneath the gums or bone and cannot erupt into its proper position. While wisdom teeth are commonly impacted, other teeth—especially upper canine teeth—can also become impacted.

Because impacted teeth cannot emerge normally, they may affect the alignment of neighboring teeth, the bite, and overall oral health if left untreated.

Why Do Teeth Become Impacted?

Several factors can contribute to tooth impaction, including:

  • Lack of space in the dental arch
  • Crowding of nearby teeth
  • Genetics and family history
  • Abnormal tooth position or eruption path
  • Extra teeth blocking eruption
  • Delayed loss of baby teeth

Upper canine teeth are particularly prone to impaction because they follow a long and complex eruption path.

Common Signs of an Impacted Tooth

In many cases, impacted teeth do not cause pain and are discovered during a routine dental or orthodontic examination.

Signs may include:

  • A permanent tooth that has not erupted on schedule
  • A baby tooth that remains in place longer than expected
  • Crowded or shifting teeth
  • Swelling or tenderness in the gums
  • A noticeable gap where a tooth should be

Digital X-rays and 3D imaging help orthodontists identify impacted teeth and determine the best treatment approach.

Which Teeth Are Most Commonly Impacted?

The teeth most commonly affected by impaction include:

  1. Wisdom teeth
  2. Upper canine teeth (eye teeth)
  3. Premolars

Among these, impacted upper canines are one of the most common orthodontic concerns because they play an important role in both smile aesthetics and bite function.

How Are Impacted Teeth Treated?

Treatment depends on the tooth's position and the patient's age.

Options may include:

Monitoring Growth and Development

For younger patients, regular orthodontic evaluations can help identify potential eruption problems early.

Creating Space

Braces or clear aligners may be used to create room for the impacted tooth to emerge.

Removal of Baby Teeth

In some cases, removing a retained baby tooth can encourage the permanent tooth to erupt naturally.

Surgical Exposure and Orthodontic Guidance

If the tooth remains trapped, an oral surgeon may uncover the tooth, and orthodontic treatment can gently guide it into its proper position.

Can Impacted Teeth Be Prevented?

While not all impacted teeth can be prevented, early orthodontic evaluations can identify potential concerns before they become more complicated.

The American Association of Orthodontists recommends that children have their first orthodontic evaluation by age 7. Early monitoring allows orthodontists to detect eruption problems and intervene when appropriate.

When Should You See an Orthodontist?

If a permanent tooth seems delayed, a baby tooth has not fallen out, or your dentist has mentioned a possible impacted tooth, an orthodontic evaluation can help determine the next steps.

Early diagnosis often makes treatment simpler and may help avoid more complex procedures later.
