when can you start eating?

After receiving root canal treatment,

many patients ask questions like:

“Can I eat now?”

“Is it okay even though the anesthesia hasn’t worn off yet?”

If you have just finished treatment,

you may be concerned about whether

you can eat right away as usual.

If the treated tooth feels slightly heavy

or sensitive when you chew,

many people also worry

that something may have gone wrong. (ㅠㅠ)

Today, we will take a step-by-step look at

when you can eat after root canal treatment

and which foods you should be careful with!

Before explaining further,

let us briefly explain

what root canal treatment is!

A tooth may look hard on the outside,

but inside it contains soft tissue

through which nerves and blood vessels pass.

If a cavity becomes deep

or bacteria enter the inside of the tooth

through a crack or fracture,

throbbing pain or inflammation may occur.

Root canal treatment involves removing

the infected or damaged tissue,

cleaning the inside of the tooth,

and filling it with a material

to prevent bacteria from entering again.

After root canal treatment is completed,

the treatment is usually finished

by placing a crown to protect

the weakened tooth.

So,

what should you do about eating

after root canal treatment?

If you eat while the anesthesia is still active,

you may unknowingly bite your tongue

or the inside of your cheek quite hard,

so if anesthesia was administered,

it is best to wait until sensation

has sufficiently returned to your mouth

before starting a meal.

You should also be careful because

you may not properly sense the temperature

of hot food and could burn yourself.

In many cases, the anesthesia gradually wears off

after about 2 to 3 hours.

However, the time it takes for the anesthesia to wear off

varies from person to person,

so rather than focusing only on how many hours have passed,

it is important to check directly

whether sensation has returned to your lips and tongue.

Once the anesthesia has worn off,

start slowly with soft foods

such as porridge, steamed eggs, or tofu.

During root canal treatment,

the inside of the tooth is sealed

with a temporary material.

This material prevents food particles or bacteria

from entering the inside of the tooth during treatment,

but it is not as strong as the final material.

Therefore, it is best to avoid sticky foods

such as chewing gum, caramel, and taffy,

and hard foods such as ice, nuts, and candy

should also be avoided when possible,

as they may cause the temporary material to come out

or the tooth to break.

In addition, teeth undergoing root canal treatment

are often already weakened

because of cavities or fractures.

Until treatment is complete,

we recommend eating on the opposite side.

This has been an overview of eating

after root canal treatment.

The treatment process itself is important,

but the condition of the tooth over time

can also vary depending on how you use it afterward.

Avoid overusing the treated tooth,

continue with the recommended restorative treatment

and regular checkups,

and take good care of your natural tooth

to help maintain it for a long time.

In addition to brushing,

please use oral care products

to keep the spaces between your teeth

and the gumline clean! 🦷🤗
