Upper canines — often called eye teeth — play a critical role in both appearance and function. When these teeth fail to erupt naturally, patients and parents often ask:

Unfortunately, most impacted canines do NOT erupt without help. Understanding why this happens can prevent long-term damage and unnecessary delays in treatment.

What Is an Impacted Canine?

An impacted canine is a permanent tooth that:

• Remains trapped inside the jawbone or gum

• Fails to erupt at the expected age

• Has no clear eruption path

Upper canines are the second most commonly impacted teeth after wisdom teeth.

Normal Eruption Timeline for Canines

• Primary (baby) canines erupt around age 2

• Permanent canines usually erupt between 11–13 years

If a canine hasn’t erupted by this age, further evaluation is required.

Main Reasons Impacted Canines Don’t Erupt Naturally!

1. Lack of Space in the Jaw

Crowding is the most common cause.If there isn’t enough room in the dental arch, the canine cannot move into position and remains trapped.

2. Abnormal Eruption Path

Canines have the longest eruption path of all teeth.Even a slight deviation can cause the tooth to drift:

• Toward the palate

• Toward adjacent tooth roots

• Deep inside the bone

Once this happens, spontaneous eruption is unlikely.

3. Retained Baby Canine

When the primary canine doesn’t fall out on time, it blocks the permanent tooth’s eruption path.

Early extraction of the baby tooth can sometimes help — but only if detected early.

4. Thick Bone or Gum Coverage

In some patients, the bone or gum covering the tooth is too thick for eruption to occur naturally.

5. Genetic Factors

A family history of impacted teeth increases the risk.Some jaws simply develop in a way that restricts normal eruption.

6. Late Diagnosis

The longer an impacted canine remains untreated, the less likely it is to erupt on its own.After a certain age, natural eruption becomes nearly impossible.

Why “Waiting and Watching” Can Be Risky?

Leaving an impacted canine untreated can lead to:

• Damage to neighboring tooth roots (root resorption)

• Formation of cysts

• Infection

• Bite imbalance

• Longer and more complex orthodontic treatment

• Eventual tooth loss

Waiting rarely improves the situation — it often makes treatment more difficult.

Can Braces Alone Pull an Impacted Canine?

No.Braces cannot move a tooth that is fully covered by bone or gum.

Orthodontic force works only after the tooth is surgically exposed.

How Surgical Exposure Helps?

Surgical exposure:

• Uncovers the tooth crown

• Creates a pathway for eruption

• Allows orthodontic attachment placement

• Enables controlled, gradual movement into position

This preserves the natural tooth and ensures proper alignment.

When Is the Best Time for Surgical Exposure?

The ideal time is:

• During early teenage years

• When roots are still forming

• When bone is more flexible

Early exposure results in:

• Faster tooth movement

• Shorter orthodontic treatment

• Higher success rates

Diagnosis Before Surgical Exposure!

At YOUR DENTIST, evaluation includes:

• Clinical examination

• Digital OPG X-ray

• 3D CBCT scan to determine:

  • Exact tooth position

  • Depth and angulation

  • Relationship to nearby roots

This ensures safe, precise surgical planning.

What Happens After Exposure?

• Orthodontic traction begins after healing

• Tooth is slowly guided into position

• Regular follow-ups monitor progress

Most impacted canines erupt successfully when managed early and correctly.
