Godeok Station Dental Clinic, Why Does Resin Treatment for Gum Notches (Cervical Abrasion) Keep Falling Off?

Hello.

I am the director of Seoul Bardi Dental Clinic.

Have you ever been startled because your teeth suddenly felt

"sharp!"

when drinking cold water?

When you look in the mirror, the area where the tooth meets the gums

looks as if it has been struck by an ax,

with a deep notch...

We call this

"cervical abrasion."

Usually, materials such as resin or GI are used

to fill the notched area,

but the problem is that they often fall off.

"I filled this last time, but it came off again. ㅠㅠ"

Why does this keep happening?

Today, along with the hidden reason,

I’ll share a case of treating a severely notched front tooth.

Cervical abrasion,

Why does the filling keep falling off?

Godeok Station Dental Clinic, Why Does Resin Treatment for Gum Notches (Cervical Abrasion) Keep Falling Off?

There are two main causes of the tooth neck area becoming notched.

One is improper brushing habits, such as brushing too forcefully from side to side,

and the other is

excessive biting force (occlusal force) applied to the teeth.

If the filling keeps falling off, you should pay attention to the latter:

"occlusal force."

Every time the upper and lower teeth come together,

the teeth bend very slightly to the side.

But if the chewing force is too strong

or only certain teeth are biting hard,

then the enamel in the weakest area, the tooth neck (cervical area),

starts to break away.

The professional term for this is

"abfraction."

This goes beyond simple surface wear;

it is a structural problem caused by the tooth bending under occlusal force.

No matter how firmly resin is bonded to a tooth

that keeps being hit like it’s being hammered,

every time excessive force is applied,

the resin has no choice but to pop off.

A case that required both a crown and an implant

due to severe abfraction

Godeok Station Dental Clinic, Why Does Resin Treatment for Gum Notches (Cervical Abrasion) Keep Falling Off?

A patient who visited our clinic recently

was deeply concerned because the resin kept falling off.

There was cervical abrasion overall,

but

in particular, the two upper left teeth (#22 and #23)

were especially deeply notched.

Because the notched area was quite large,

the nerve had already been exposed.

Why were these two teeth

so severely notched?

The reason became clear as soon as we looked at the lower teeth.

250317

The patient ate much more on the left side than the right,

and the lower left teeth were severely worn down,

so the chewing force on the left side was overwhelmingly stronger.

In a structure where occlusal force is concentrated on one side like this,

it may be natural that even a carefully done filling

falls off again after just a few days.

Treatment plan and process for cervical abrasion

Because the notched area was already too large

and the nerve was exposed,

simply "filling it" was no longer meaningful.

So we planned crown treatment after root canal treatment.

However, there was one major variable here:

the second front tooth (#22).

The neighboring canine (#23) had a deep root and strong bone support,

so after root canal treatment, placing a crown on it

would allow it to be used for a sufficiently long time,

but

the small front tooth next to it (#22) was a bit different.

Compared with the canine, the bone around the root had resorbed significantly,

and mobility was already observed.

We could perform root canal treatment

and force a crown onto it,

but

how long would this tooth really be able to withstand strong occlusal force?

Rather than spending unnecessary money and time

on a tooth that would likely need to be extracted soon,

we decided that an implant would be better for the long-term prognosis.

We explained the current condition honestly to the patient,

and in the end,

we decided to save the canine with root canal treatment and a zirconia crown,

and proceed with an implant for the mobile small front tooth.

A prosthesis created through our in-house lab,

balancing aesthetics and stability

Since the implant and crown would be placed side by side,

the harmony with the surrounding teeth was especially important.

We have a specialized lab inside the clinic.

Using the patient’s occlusal data,

which we analyzed in detail,

I and the head technician communicate closely

by sharing information in real time.

To disperse the strong force concentrated on the left side,

we not only designed the shape and angle of the prosthesis

with great precision,

but also reproduced the color and texture of the surrounding teeth as closely as possible.

Using high-strength zirconia that is suitable for patients with strong biting force,

we made it so they could eat comfortably without worrying about fracture.

Just because a tooth is notched does not mean

that filling it with resin is always the best answer.

The first question should be:

"Why did this area become so notched?"

If the filling keeps falling off,

or if you feel the tooth neck area gradually getting deeper,

it may not be simple wear,

but a problem with your bite.

Don’t keep worrying about it alone—

what forces your teeth are enduring,

and which treatment is the best choice for you.

We will help you carefully with an accurate diagnosis

and the treatment that matches it.

Thank you^^
