Hello.

We are The Square Dental Clinic, which focuses on conservative and restorative treatment.

If one day you suddenly feel a sharp, “zinging” pain when chewing hard foods,

or you casually look in the mirror and notice a crack in your tooth?

At times like this, many people delay visiting the dentist because they worry that

they might be told to have the tooth extracted. (^^;)

To give you the conclusion first, for those with tooth crack symptoms,

in some cases treatment may not be necessary,

and even if treatment is needed, extraction is not always required.

So there is no need to be afraid in advance.

In other words, if the right action is taken at the right time, it is fully possible to save your precious natural tooth.

In this post, we will calmly go over the following three topics:

  1. Whether treatment is needed depending on tooth crack symptoms

  2. “Tooth crack resin” for addressing microcracks

  3. The armor that protects teeth: “tooth crack crown”

Tooth crack symptoms,

“When this happens,” treatment is needed. As mentioned, a cracked tooth does not always lead to treatment.

Teeth are consumable, so after many years of use, tiny cracks can appear in anyone’s teeth.

If your tooth crack symptoms are

✔️ a crack only in the outermost layer of enamel, or ✔️ even if the crack extends to dentin, it is only mild,

then you can monitor it with regular checkups to see whether the crack worsens.

However, if the tooth crack symptoms progress further, for example:

  • severe sensitivity when eating cold or hot foods
  • pain so intense that you cannot sleep at night
  • increasing frequency and intensity of pain

this means it has progressed to pulpitis, and natural healing is not possible.

Therefore, you should visit a dental clinic as soon as possible.

If you miss this window, the tooth may split completely and extraction may become necessary.

Tooth crack symptoms,

“Tooth crack resin” that blocks microcracks If you search for tooth cracks, you may have felt confused because each source recommends different treatments, such as

tooth crack resin vs. tooth crack crown.

Let me clearly sort that out here.

If the crack is very early or falls into one of the following cases,

📌 the crack has caused only a very small chip at the corner of the tooth 📌 there is almost no pain when chewing 📌 the crack remains shallow and limited to the enamel

then tooth crack resin treatment may be considered.

Tooth crack resin involves gently refining the cracked area and filling the gap with dental resin.

Treatment can be done on the same day, the cost burden is relatively low,

and above all, its biggest advantage is that it preserves the natural tooth almost as it is.

However, tooth crack resin may not be suitable for molars that are under strong biting pressure or for cracks that have already progressed deeply.

This is because it lacks the strength to firmly hold teeth that are spreading apart.

If resin is forced in such cases, the crack may worsen even faster.

Tooth crack symptoms,

“Tooth crack crown” that becomes armor If the crack has progressed beyond the enamel to the dentin,

then you need the strength to hold the tooth so it does not spread further or split.

A tooth crack crown can be that solution.

A tooth crack crown is a treatment in which the tooth is reshaped overall,

and then covered with a strong prosthetic such as gold or zirconia.

Because a restoration is placed over the tooth, there is some burden in that a certain amount of tooth structure must be removed,

but it can distribute chewing force, fundamentally prevent tooth fracture, and help extend the tooth’s lifespan.

However, many people hear “tooth crack crown” and think

that root canal treatment is always necessary and become frightened...

  • Key point: According to a 6-year long-term follow-up study published in the world’s most authoritative international endodontic journal, when crown treatment was performed at an early stage for tooth crack patients with slight pain when chewing, approximately 80% of patients regained healthy tooth function without root canal treatment, with the pain disappearing.

  • Source: J Endod. 2007 Dec;33(12):1405-7. doi: 10.1016/j.joen.2007.08.015. Epub 2007 Oct 22.

If there is no pain and only a tiny crack,

treatment with a crown alone may be possible without root canal treatment.

Tooth cracks often do not show clearly even to the naked eye or on X-rays,

so the dentist’s diagnostic ability is very important.

So for those of you reading this,

if you want a more accurate diagnosis and treatment that is right for you,

✅ Do they have precision diagnostic equipment that can detect even tiny cracks inside the clinic?
✅ Are specialists in fields such as orthodontics/general dentistry on site to create a treatment plan that takes into account not only the tooth condition but also the bite?
✅ Do they practice with a medical philosophy that aims to preserve the patient’s natural teeth as much as possible?

I recommend carefully evaluating these points when choosing a dental clinic.

However, if a non-specialist individual delays treatment based on their own judgment,

there may come a time when they need more complex treatment that costs more and takes more time.

In other words, if you are worried, it is more efficient to visit a dental clinic as soon as possible for a precise diagnosis,

and to hear the doctor’s practical advice as well.
