Are Differences in Root Canal Crown Lifespan Caused by the Type?

Did you know that root canal treatment causes structural changes?

As a treatment to remove inflammation or infection inside the tooth,

it is performed when the condition is significantly poor, such as tooth discoloration or discomfort in the gums even while resting.

In the process of removing the pulp tissue inside the tooth (nerve and blood vessel tissue),

the tooth loses its nutrient supply and gradually becomes weaker.

It changes into a vulnerable state that can be easily damaged by external pressure.

At this point, placing a crown can greatly improve structural stability.

I’ll explain more below.

There is a reason for getting a crown!

When treating cavities or performing root canal treatment,

a crown is often done together.

It is not only for improving appearance.

It also surrounds the entire tooth, disperses force,

and helps restore chewing function more stably.

As mentioned earlier, after root canal treatment,

the risk of fracture increases and the internal structure weakens,

so using the tooth without a prosthetic restoration leaves it vulnerable to external stimuli,

which is why it must be done.

In other words, it serves as a protective barrier around the tooth

and is an important step that makes long-term use possible.

Just as you need to wear a helmet when riding a bicycle or motorcycle

to reduce the impact transmitted if your head hits something,

you can think of it in that way.

How long does a root canal crown last?

Generally, it is about 7 to 15 years.

Since it varies from person to person,

this is closer to a reference value than an absolute standard.

If the bite is stable

and oral hygiene is carefully maintained,

there are cases where it lasts even longer.

Habits such as teeth grinding,

an imbalanced bite, or accompanying gum disease

can shorten its lifespan.

The maintenance period can vary greatly depending on the oral environment.

Different characteristics and the period for maintaining intact condition by material

Depending on the material used, strength, esthetics,

wear characteristics, and thermal conductivity differ.

PFM has a color similar to natural teeth

and is relatively less expensive than the two materials below,

but it has less translucency, and over time,

the internal metal may become visible and may look like decay.

Zirconia has excellent strength and color stability,

so it is chosen frequently by patients,

but if it is made too thin, the risk of fracture increases.

Gold is strong, but because it is gold-colored,

it has the advantage and disadvantage of being less esthetic.

No matter which material you choose, the lifespan of a root canal crown

is determined by the combined effects of its characteristics and maintenance.

It is not greatly related to whether the cost is low or high.

If a problem occurs, the lifespan shortens.

Even if it looks fine from the outside,

if inflammation or secondary decay occurs,

the lifespan may become shorter.

In particular, if the margin at the boundary area lifts up,

or if you repeatedly feel like food is getting stuck,

you cannot rule out the possibility that a problem has developed inside.

Because sensation becomes dulled and problems often progress without pain,

constant caution is necessary.

To prevent such situations,

regular observation and early response are essential.

Management habits have a major effect on how long it lasts.

To use it for a long time, please reduce your intake of hard, sticky,

and chewy foods.

If you usually clench your teeth frequently or when sleeping,

or grind them,

do jaw massage and exercises every day

to relieve tense muscles.

If it still does not improve,

it may be good to consider wearing a mouthguard

or getting jaw Botox.

If the habit is wrong,

it can affect not only the tooth that had root canal treatment

but also other teeth.

Because food can get stuck easily,

careful brushing around the teeth and gums

and hygiene management using oral aids are also necessary.

If you feel discomfort, it is also good to visit the dental clinic

for a checkup and treatment.

The process of getting root canal treatment and then placing a crown

is also the starting point of proper care.

No matter how good the material is,

the lifespan can vary depending on the bite, lifestyle habits,

and care methods.

To keep the lifespan of a root canal crown long,

reducing excessive use and repeatedly making hygiene care and regular checkups a habit

may be the best approach.
