Hello, this is E-Pyeonhan Sesang Dental Clinic.

One of the treatments many patients find difficult is root canal treatment.

Because it is hard to finish in one visit and often requires several appointments, many people find it inconvenient.

Since visits are frequent, there are also care points that need attention after treatment just as often.

One of them is alcohol.

Many people know that drinking after root canal treatment is not good, but they often wonder why it is not good and when they can start drinking again.

So today, we have prepared a detailed look at this topic.

| ① Teeth that have finished root canal treatment are sensitive. |

Before talking about whether you can drink after root canal treatment, let’s briefly talk about the condition of a tooth that has completed root canal treatment.

Root canal treatment refers to the procedure of removing damaged nerve and blood vessel tissue from inside the tooth.

Once removed, a hollow space is created inside, and root canal treatment involves disinfecting that space and filling it with a material.

Although it may look as if the treatment is finished on the outside, the gum bone and gums around the tooth, as well as the tissues around the root canal, are actually in a sensitive state.

Therefore, a recovery and adjustment period is needed.

In particular, right after treatment, inflammation may remain around the tooth root, or the damaged tissues may be in the process of recovering, making the area more sensitive to stimulation.

So everyday habits that normally seem harmless can become significant irritants, and caution is needed.

| ② Do not drink alcohol after root canal treatment |

The reason I mentioned in advance that the tooth is sensitive after root canal treatment was to explain why alcohol should not be consumed after the procedure.

As you may have already guessed, you should not drink alcohol after root canal treatment.

When alcohol enters the body, the alcohol in it causes blood vessels to expand, lowers immune function, and slows the rate of regeneration.

These bodily changes can cause various problems after treatment.

When blood vessels expand during drinking, blood flow increases. This can further encourage inflammation, and especially if inflammation around the root has not fully subsided, swelling or pain may become worse.

Also, alcohol weakens the function of white blood cells, temporarily reducing the body’s defense against bacteria.

Because the treated area is still healing, if this condition continues due to drinking, the risk of bacterial infection may increase.

Lastly, you should abstain from alcohol because you will likely be prescribed painkillers and antibiotics.

After root canal treatment, painkillers and antibiotics are prescribed to control pain.

If you drink alcohol while taking these medications, healing may slow down, side effects may occur, or the medication’s effectiveness may decrease, so it is best to avoid alcohol completely.

| ③ After root canal treatment, when can you drink? |

So, when can you drink after dental root canal treatment?

To give the conclusion first, it is best to drink at least one week after treatment is completed.

Root canal treatment usually does not end in a single visit, but is carried out over 2 to 4 sessions.

Alcohol avoidance is recommended during treatment and after the treatment is completely finished.

During treatment, the inside of the tooth is sealed with temporary material, so it is sensitive and inflammation can easily occur.

If inflammation develops, the treatment period may become longer, so abstaining from alcohol is recommended.

Also, after all treatment is completed, the tissues around the root need time to heal stably.

This period is about 5 to 7 days.

Therefore, we recommend waiting about one week after root canal treatment before drinking alcohol, and if the inflammation was severe before treatment, please remember that the abstinence period may need to be longer.

| ④ Please still be careful about these situations after root canal treatment |

Even after root canal treatment is finished, the treated tooth does not immediately become healthy.

Treatment completion simply means that the dental procedures that can be done at the clinic are finished; the surrounding gum bone, gums, and the area at the tip of the root still require ongoing healing.

Therefore, it is important to carefully monitor symptoms after treatment.

If a panoramic X-ray shows apical inflammation after treatment, extra caution is needed.

Before root canal treatment, inflammation spreads to the tip of the tooth root, so instead of healthy white gum bone, the inflamed area appears dark.

After treatment, it is normal for this area to gradually shrink over time and be filled in with gum bone.

However, if the inflammation is severe or if recovery takes a long time, the inflamed area may still be visible on the panoramic image even after treatment.

In that case, it is best to focus as much as possible on recovery, including avoiding alcohol and smoking, so that the inflammation does not grow again and healing can proceed well.

Also, caution is needed if pain persists when chewing or if a dull, sensitive pain is felt. If the gums around the treatment area continue to swell or feel warm, additional treatment may be needed, so it is best to contact the dental clinic in that case.

In today’s post, I said that after finishing root canal treatment, you may be able to have one or two light drinks after one week.

In fact, this can vary from person to person.

It can depend on the current condition of the tooth and surrounding tissues, the degree of inflammation, and an individual’s recovery speed, so it is important to decide the details through consultation with the medical staff.

This may be disappointing for people who enjoy drinking, but I hope you remember that a tooth you must use for the rest of your life is more valuable than a brief period of drinking.

This has been E-Pyeonhan Sesang Dental Clinic.

Thank you.
