What are the types of tooth cracks?

Cracks vary in depth, length depending on the location of the tooth.

Craze lines

They are the smallest cracks that occur on the tooth enamel. They are hard to be noticed since they don’t cause pain and require no treatment.

Split tooth:

The crack splits the tooth into two. A dentist can only save one part of the tooth using a


In other cases root canal treatment can be used.

Oblique subgingival cracks

The cracks are painful and extend below the gum line.

Oblique supragingival cracks:

They don’t go below the gum line and affect the crown only. They are not painful.

Fractured cusp

This happens if a piece of the chewing surface gets broken. It is commonly found around the dental filling.

Oblique root cracks

The cracks do not happen on the surface of your tooth. The damage usually occurs below the jawbone.

Vertical root fracture:

The crack starts below the gum line and extends upward.

How to diagnose a cracked tooth?

It is not always simple to diagnose a cracked tooth, especially if the crack is small.

X-rays cannot also help locate the crack To help diagnose the tooth, the dentist will do the following:

Ask your dental history:

Whether you grind your teeth or chew very hard food.

Do a visual examination:

Your dentist uses a magnifying lens to enlarge small cracks.

Feel for a crack

The doctor runs a dental explorer around your teeth to find if it ‘catches’ on an edge.

Use of dental dye:

This makes the crack to stand out.

Probes your gum to look for an inflammation:

It is very important in locating vertical cracks that irritates the gum.

Having you bite something:

When you release the bite you feel the pain and that is a sign of a cracked tooth.

X-ray the teeth:

The X-rays may not reveal where the cracks are located but can reveal problems in teeth pulp. Unhealthy pulp suggests a crack.

How to treat a cracked tooth?

The treatment is based on where the crack is located and the damage caused.
Treatment is not necessary if the crack is tiny and no discomfort is caused.

In cases of extensive cracks the following treatments are done by a dentist:


Plastic is used to fill the crack and this restores its look and function.

Using a crown:

A dental crown is made of ceramic or porcelain. It is fitted on the damaged tooth or capped on it.


If the tooth, and roots and nerves below it, are damaged, the only option is to remove it.

Root canal:

In very severe cases the crack may have penetrated the pulp, root canal is done.
Gluing on the broken or chipped part of the tooth.

How to prevent a cracked tooth?

It is not a preventable condition, but these strategies can help:

Avoid chewing hard foods such as unpopped popcorn kernels and ice.
Try not to clench your teeth.
Avoid habits that can damage your teeth such as biting pens or grinding.
Wear a mouth guard while in sporting activities.


It is a common experience for many people to have a cracked tooth. There are many ways to save your teeth and their appearance.
Although the tooth can be treated, it cannot be 100 percent healed, unlike broken bones do.

Prompt treatment will save your tooth and prevent it from further damage and infection.
