Hello.

We are The Square Dental Clinic, where we first look for ways to preserve teeth as much as possible.

When Your Front Tooth Breaks: This Is What Determines Whether It Can Be Finished with Resin or Needs a Crown image 1

When a front tooth breaks,

have you asked yourself these three questions?

"Do I have pain right now?"

"How much broke off?"

"Since when has it been like this?"

There is one criterion that is even more important than these questions.

It is how far the damage extends into the tooth layers.

When a front tooth breaks, it is often difficult to judge the extent of the damage based only on the visible size.

Even if it looks small on the surface, there can be cracks that extend into the inner layers.

So today, let’s organize how to distinguish front tooth fractures step by step,

and which criteria should be checked first to better understand the condition.

[Key points to check immediately when a front tooth has a crack]

A broken front tooth should be checked starting with the internal structure, not just what is visible on the surface. When Your Front Tooth Breaks: This Is What Determines Whether It Can Be Finished with Resin or Needs a Crown image 2

Just because a front tooth is broken does not mean every case is handled the same way.

The important criterion is how far into the layers the damage has progressed.

A tooth is broadly made up of four layers.

| Enamel (outer layer) | The hardest outermost layer. If the damage is shallow, its shape can be restored with resin.

| Dentin (inner layer) | If the inner layer becomes exposed,

sensitivity may appear,

and if stimulation is repeated,

it can affect the internal tissue.

| Nerve (pulp) | If the damage reaches the nerve,

pain or inflammation may occur,

and root canal treatment is needed.

| Root | If the crack progresses toward the root,

the possibility of keeping the tooth should be evaluated first,

and extraction may be considered depending on the situation.

One point to pay special attention to is that

it is difficult to conclude that the damage is shallow just because there is no pain.

Even if it looks like only about 1 mm has broken off on the outside,

there are many cases where the crack continues slowly downward inside.

So when a front tooth breaks, the first important step is to check how deep the damage goes.

Checking early is the most realistic way to save the tooth. When Your Front Tooth Breaks: This Is What Determines Whether It Can Be Finished with Resin or Needs a Crown image 3

The direction of treatment after a front tooth fracture often changes depending on when it is checked.

If the condition is checked early, it can often be managed with a relatively simple method,

but if time passes and the damage becomes deeper,

the available options may decrease.

If checked early ✔️ Resin restoration ✔️ Reattachment of the broken fragment ✔️ Nerve protection

If checking is delayed ✔️ Crown prosthesis needed ✔️ Root canal treatment ✔️ Extraction in severe cases

However, checking early does not always mean it will end with a simple procedure.

If the nerve was already damaged at the moment the trauma occurred,

then even if it is checked quickly,

root canal treatment may still be necessary.

In particular, if you notice the following changes,

it would be a good idea to have the condition checked.

A strange feeling only from a certain direction when eating
A sudden sharp sensation when drinking cold water
A clear crack visible when looking in the mirror
A sharp edge felt when touching it with your tongue

These signs may be early signals that appear before the problem progresses further.

Therefore, not missing this timing and checking the condition in advance helps widen your options later.

What matters first is not what to do, but what the current condition is. When Your Front Tooth Breaks: This Is What Determines Whether It Can Be Finished with Resin or Needs a Crown image 5

"Should I get resin?"

"Should I get a crown?"

We receive this question often.

But what should be checked first is which stage the tooth is currently in.

At The Square Dental Clinic, we first look at the following four criteria.

※ Depth of damage

(enamel / dentin / nerve / root)

※ Whether the nerve is exposed

※ How force is distributed when biting together

※ Stability of the remaining tooth structure

Based on these criteria,

the direction is decided according to the stage,

including whether resin restoration, crown prosthesis, root canal treatment, or extraction is appropriate.

In addition, it is necessary to check not only the visible size of the fracture,

but also the direction in which the crack is progressing and how the force on the surrounding teeth is changing.

Even with the same size of fracture,

the period during which the tooth can be preserved and the follow-up care may differ depending on the structural conditions.

Rather than rushing with "We need to proceed right away," we place importance on

first explaining the current condition accurately

and then deciding the next step together.

When a front tooth breaks, at The Square Dental Clinic we first proceed with these three steps.

① Accurate stage diagnosis

We first check not the visible size of the fracture,

but how deep the actual damage has progressed.

② Explanation of options

We objectively explain the methods that can be applied in the current condition and the pros and cons of each,

and also explain the criteria by which the choice changes.

③ Decide together

Rather than rushing with "You need treatment right away,"

we place importance on the process of fully understanding the current condition

and then deciding the direction together.

Even without pain, internal damage can progress quietly.

But if you check accurately at this stage,

you can sufficiently reduce the extent of progression before it reaches an irreversible stage.

Only as much as needed,

accurately.

Based on that standard, The Square Dental Clinic is carrying out diagnoses.
