DENTAL CONCERN

Damaged Teeth

Also called: broken tooth, chipped tooth, cracked tooth, damaged teeth, worn teeth, decayed tooth, cracked filling, old fillings, tooth broke off

Damaged teeth can include teeth that are chipped, cracked, fractured, worn or otherwise weakened. Damage can range from small changes to the enamel to deeper fractures affecting the internal structure of the tooth, sometimes causing sensitivity, pain or difficulty biting.

TYPICALLY OCCURS

Injury, decay, grinding, biting hard foods and tooth wear.

TREATED BY

Crowns, veneers, bonding, fillings and root canal treatment.

Why it happens?

Teeth are naturally strong, but their structure can become damaged when subjected to forces beyond what they can withstand. Accidents, falls, sports injuries or biting unexpectedly hard foods or objects can cause a tooth to chip, crack or fracture. Teeth can also gradually wear down through repeated grinding or clenching, known as bruxism, which places significant pressure on the enamel and may eventually lead to cracks, flattened surfaces or small fractures.

The condition of the tooth before an injury also matters. Tooth decay removes healthy dental tissue and can weaken the remaining structure, making the tooth more vulnerable to breaking under normal chewing pressure. Large or older fillings may leave less natural tooth structure available to support the tooth. Previous dental procedures, erosion of the enamel and general wear over time can similarly affect strength. Acidic foods and drinks, acid reflux and other sources of repeated acid exposure can gradually erode enamel, leaving teeth thinner and more susceptible to sensitivity, wear and damage.

Not all tooth damage is immediately obvious. Very small cracks may initially cause few symptoms but can become more noticeable as they extend or the tooth is repeatedly placed under pressure. Deeper damage can expose the dentine or reach the pulp, where the tooth’s nerves and blood vessels are located. At this point, sensitivity, pain or inflammation may develop, and bacteria can potentially enter the tooth. The significance of a damaged tooth therefore depends not only on how it looks, but also on how deeply the tooth structure has been affected.

How far along is it?

Early

Small chips, superficial cracks or mild enamel wear affect the outer surface of the tooth, often with little or no discomfort.

Moderate

A larger chip, crack or area of wear reaches deeper tooth structure. Sensitivity, discomfort when biting or a noticeable change in the tooth’s shape may develop.

Advanced

A deep fracture or extensive structural loss may reach the pulp or significantly weaken the tooth. Pain, infection or substantial difficulty biting may occur, and urgent dental assessment may be necessary.

A visibly chipped, cracked or broken tooth is worth having assessed even if it is not painful. Minor enamel damage may require little intervention, but deeper cracks and fractures can become more difficult to manage if the tooth continues to experience pressure.

Seek dental attention promptly if tooth damage causes significant pain, sensitivity, swelling, bleeding or difficulty biting. A tooth that has become loose, substantially fractured or knocked out following an injury requires urgent dental assessment.

Quick Questions:

Can a damaged tooth repair itself?

Enamel that has been physically chipped or lost does not grow back. Very early mineral loss can sometimes be remineralised, but cracks, fractures and significant structural damage generally require professional assessment.

How do I know if my tooth is cracked?

A cracked tooth may cause pain when biting or releasing pressure, sensitivity to hot or cold, or intermittent discomfort. However, some cracks produce few obvious symptoms and may only be identified during a dental examination.

What happens if a damaged tooth is left untreated?

This depends on the type and depth of damage. Some minor chips remain stable, while deeper cracks can progress and allow bacteria to reach the inside of the tooth, potentially resulting in inflammation, infection or further structural damage.

Can a badly damaged tooth be saved?

Often, but it depends on how much healthy tooth structure remains and whether the root and internal tissues are affected. Depending on the damage, options can include bonding, fillings, veneers, crowns or root canal treatment. In some severe cases, the tooth may not be restorable and extraction may need to be considered.
