A tooth usually follows a predictable path as it develops and emerges through the gums. However, sometimes a tooth cannot erupt into its expected position. It may remain trapped beneath the gum tissue, become partially visible, or grow at an angle that prevents normal eruption.
This condition is known as tooth impaction.
An impacted tooth may cause no noticeable symptoms, especially in its early stages. In other cases, it can contribute to discomfort, gum inflammation, crowding, or damage to neighboring teeth.
Although wisdom teeth are commonly associated with impaction, other teeth, including the upper canine teeth, can also become impacted. Understanding the cause and location of the problem helps determine whether monitoring, orthodontic treatment, or another intervention may be appropriate.
At Pacha & Bijan Dental in Maitland, FL, a dental evaluation can help identify an impacted tooth and determine the next steps based on the patient's individual needs.
What Is an Impacted Tooth?
An impacted tooth is a tooth that has not erupted into its expected position within the dental arch because its eruption is obstructed or otherwise disrupted.
Teeth develop inside the jaw before moving toward the oral cavity. During eruption, the developing tooth follows a path through the surrounding bone and gum tissue.
When that path is blocked or the tooth develops in an unfavorable position, eruption may be delayed or prevented.
An impacted tooth may be:
- Completely impacted: The tooth remains entirely beneath the gum tissue and may also be enclosed in bone.
- Partially impacted: Some of the tooth has emerged, but the remainder is still covered by gum tissue or blocked by surrounding structures.
- Ectopically positioned: The tooth develops or erupts in an abnormal position or direction.
These descriptions help dentists understand the tooth's position, but the appropriate treatment depends on more than whether the tooth is visible.
Why Do Teeth Become Impacted?
Tooth impaction can occur for several reasons. In many cases, more than one factor contributes.
Insufficient Space in the Dental Arch
A tooth needs sufficient space to erupt into its expected position.
If the jaw does not provide enough room, the tooth may become trapped or emerge at an angle.
Crowding can contribute to impaction, particularly when several teeth are competing for limited space.
Abnormal Tooth Position
A developing tooth may be angled incorrectly or follow an unusual eruption path.
Even when space is available, an unfavorable position can prevent the tooth from emerging normally.
Obstruction by Another Tooth
A neighboring tooth may block the eruption path.
This can prevent the developing tooth from reaching its normal position and may affect the alignment of the surrounding teeth.
Extra Teeth or Other Obstructions
An additional tooth, known as a supernumerary tooth, can sometimes obstruct the eruption of a permanent tooth.
Other abnormalities involving the surrounding tissues may also interfere with eruption.
Developmental Factors
Tooth development and eruption are influenced by genetics, jaw growth, and the timing of dental development.
In some patients, these factors may contribute to delayed or abnormal eruption.
Identifying the precise cause may require a clinical examination and dental imaging.
Which Teeth Are Most Commonly Impacted?
Several teeth can become impacted, but some are affected more frequently than others.
Wisdom Teeth
Wisdom teeth, also called third molars, are located at the back of the mouth.
They often erupt later than other permanent teeth, when the available space in the dental arch may be limited.
Their position and eruption pattern can make them susceptible to impaction.
Upper Canine Teeth
Upper canines, sometimes called eye teeth, play an important role in the appearance and function of the smile.
They typically erupt after the permanent incisors and before the premolars.
If an upper canine becomes impacted, it may remain beneath the gum tissue rather than emerging into its expected position.
This can affect alignment and, in some cases, the neighboring teeth.
Premolars and Other Permanent Teeth
Premolars and other permanent teeth can also become impacted, particularly when an obstruction or developmental problem interferes with eruption.
The specific tooth involved influences the diagnostic process and treatment options.
What Are the Symptoms of an Impacted Tooth?
An impacted tooth does not always cause symptoms.
Some cases are discovered during routine dental examinations or when X-rays are taken for another reason.
When symptoms occur, they may include:
- Pain or tenderness in a particular area
- Swelling around partially erupted teeth
- Red or irritated gum tissue
- Food trapping around a partially erupted tooth
- Difficulty cleaning the affected area
- Persistent bad breath associated with local inflammation
- Crowding or changes in tooth alignment
- A permanent tooth that has not erupted when expected
These symptoms are not exclusive to impaction. Other dental conditions can produce similar signs, so an examination is necessary to establish the cause.
Can an Impacted Tooth Damage Neighboring Teeth?
In some cases, yes.
An impacted tooth may press against an adjacent tooth or develop in a position that interferes with its normal structure.
Depending on the location and direction of the impacted tooth, potential complications may include:
- Damage to the root of a neighboring tooth
- Localized bone changes
- Displacement of adjacent teeth
- Problems with normal eruption
- Development of a cyst associated with the impacted tooth
Not every impacted tooth causes these complications.
The risk depends on factors such as the tooth's position, its relationship to neighboring structures, and whether a developing problem is present.
This is one reason dentists evaluate impacted teeth even when they are not painful.
How Is an Impacted Tooth Diagnosed?
Diagnosis involves determining which tooth is affected, where it is positioned, and whether it is causing or likely to cause complications.
Step 1: Clinical Examination
Your dentist examines the mouth for missing permanent teeth, abnormal eruption patterns, swelling, and other signs that may suggest impaction.
The gum tissue is also evaluated for inflammation or infection.
Step 2: Reviewing Dental Development
The dentist may ask about your dental history, previous orthodontic treatment, and whether a permanent tooth has failed to appear at the expected time.
In children and teenagers, the timing of eruption is particularly relevant.
Step 3: Dental X-Rays
Dental imaging helps reveal teeth that remain beneath the gums or inside the jawbone.
X-rays can show the tooth's position, angle, and relationship to neighboring roots.
The type of imaging depends on the clinical question. Additional imaging may be recommended when the location or relationship to important structures requires further assessment.
Step 4: Evaluating Potential Complications
The dentist considers whether the impacted tooth is affecting neighboring teeth, surrounding bone, or soft tissues.
The findings help determine whether the tooth can be monitored or whether treatment should be considered.
Step 5: Developing a Treatment Plan
The recommended approach depends on the patient's age, the tooth involved, its position, the condition of adjacent teeth, and the likelihood of successful treatment.
In some cases, observation is appropriate. In others, intervention may help preserve dental function and prevent complications.
What Are the Treatment Options for an Impacted Tooth?
Treatment is not the same for every impacted tooth.
The goal is to address existing problems, reduce the risk of future complications, and preserve healthy teeth whenever possible.
Monitoring
An impacted tooth may be monitored when it is not causing symptoms or damaging surrounding structures and when observation is considered clinically appropriate.
Monitoring may include periodic examinations and imaging when indicated.
Observation does not mean ignoring the tooth. It means checking for changes that could affect the treatment decision.
Orthodontic Treatment
Certain impacted teeth, particularly upper canines, may be candidates for orthodontic treatment.
The dentist or orthodontist evaluates whether the tooth can be guided into the dental arch safely.
In selected cases, a procedure may be needed to expose the impacted tooth so that an orthodontic attachment can be placed.
The orthodontic appliance can then apply controlled forces to guide the tooth toward its intended position.
Successful treatment depends on the tooth's location, its orientation, the available space, and the health of the surrounding structures.
Surgical Exposure
Surgical exposure involves accessing an impacted tooth that remains beneath the gum tissue or bone.
This procedure may be part of a coordinated orthodontic treatment plan.
The specific technique depends on the tooth's location and the treatment objective.
Not every impacted tooth is suitable for surgical exposure and orthodontic movement.
Extraction
Extraction may be recommended when an impacted tooth cannot be positioned predictably, causes significant complications, or is unlikely to provide a useful functional result.
The decision depends on the tooth involved and the individual clinical findings.
Extraction is not automatically required simply because a tooth is impacted.
What Happens if an Impacted Tooth Is Left Untreated?
The outcome varies.
Some impacted teeth remain stable and do not produce significant problems. Others can cause complications over time.
Potential concerns include recurring inflammation around a partially erupted tooth, damage to neighboring roots, changes in surrounding bone, or cyst formation.
An impacted tooth may also interfere with orthodontic treatment or normal dental development.
Because the risks differ from one case to another, your dentist can help determine whether monitoring or treatment is appropriate.
Is an Impacted Tooth Always Painful?
No.
A tooth can remain impacted for years without causing obvious discomfort.
The absence of pain does not necessarily mean that the tooth has no effect on nearby structures.
Conversely, pain does not automatically mean that an impacted tooth is responsible.
Dental examination and appropriate imaging help distinguish impaction from other possible causes of discomfort.
When Should You Seek Dental Care?
Arrange a dental evaluation if you notice that a permanent tooth has not erupted as expected, a tooth appears to be emerging at an unusual angle, or swelling develops around a partially erupted tooth.
Seek prompt care if you experience significant pain, facial swelling, fever, pus, or difficulty opening your mouth.
Difficulty swallowing or breathing requires emergency medical attention.
Children and teenagers should also receive age-appropriate dental evaluations so that eruption patterns can be monitored and potential problems identified early.

Frequently Asked Questions
Can an impacted tooth erupt on its own?
Some teeth may erupt naturally, depending on their position, available space, developmental stage, and the presence of obstructions. Others remain trapped and may require monitoring or treatment. A dentist can assess the likelihood of natural eruption.
Are impacted teeth always removed?
No. Extraction is only one possible treatment. Depending on the tooth and clinical findings, a dentist may recommend monitoring, orthodontic treatment, surgical exposure, or extraction.
Can an impacted canine be saved?
In selected cases, an impacted canine can be guided into the dental arch through coordinated surgical and orthodontic treatment. Success depends on the tooth's position, available space, root development, and the condition of the surrounding structures.
Can an impacted tooth cause crowding?
An impacted tooth may be associated with crowding or displacement, particularly when there is insufficient space in the dental arch. However, crowding has multiple causes, and not every impacted tooth will move neighboring teeth.
How does a dentist find an impacted tooth?
A dentist examines the mouth and may use dental X-rays to identify a tooth that has not erupted. Additional imaging may be considered when more detailed information about its position is needed.
Can adults have impacted teeth?
Yes. An impacted tooth may remain undiscovered until adulthood, particularly if it does not cause symptoms. Adults can also develop problems associated with teeth that have remained impacted for years.
Can an impacted tooth become infected?
A partially erupted tooth can create an area where food and bacteria accumulate, potentially contributing to inflammation or infection. Infection is not inevitable, and fully impacted teeth can have different risk profiles depending on their position and condition.
When should an impacted tooth be treated?
Treatment timing depends on the tooth involved, the patient's age, the risk of complications, and whether the tooth can be guided into a functional position. Your dentist may recommend monitoring or intervention based on the clinical findings.
Understanding the Tooth's Position Is the First Step
An impacted tooth is not automatically a dental emergency, nor does every case require extraction.
The appropriate response depends on why the tooth failed to erupt, where it is positioned, and whether it is affecting the surrounding structures.
Early identification can help patients understand their options and make informed decisions about monitoring, orthodontic treatment, or surgical intervention when appropriate.
At Pacha & Bijan Dental, an individualized dental evaluation can help determine whether an unerupted or abnormally positioned tooth requires further assessment.
