안녕하세요.

This is E-Comfortable Life Dental Clinic!

No matter how carefully you brush your teeth, it is impossible to completely remove food particles and bacteria stuck between your teeth. These residues that are not removed create acid and act as a cause of worsening the health of your teeth and gums. Since oral care has its limits with brushing alone, it is a good idea to prevent oral diseases through scaling performed at the dental clinic.

However, many people avoid scaling because of the various uncomfortable symptoms that appear afterward. Today, together with our clinic, let’s look at why tooth sensitivity and bleeding can occur after scaling.

Tooth sensitivity after scaling,

Is it okay?

Some people feel tooth sensitivity after tartar removal at the dentist. To start with the conclusion, there is no need to worry too much. This symptom appears when scaling is performed after a long time without it, or when a large amount of tartar that had built up is removed for the first time.

As the accumulated tartar suddenly disappears, the teeth may become sensitive due to sudden exposure to the external environment. Depending on the patient’s gum condition, this may last for several days or several weeks. However, if tooth sensitivity after scaling continues for a long period of time, there may be another problem with the teeth, so it is best to visit the dental clinic and have the condition checked.

Bleeding after scaling,

Is it okay?

Sometimes, while rinsing your mouth during scaling or looking in the mirror after treatment, you may notice bleeding. Because of this, you may mistakenly think that the dental instruments used during scaling poked the gums and caused a wound.

However, this bleeding occurs as an inflammatory reaction in the gums while removing tartar and other buildup stuck between the gums. As time passes, the swollen gums subside and recover, so if you take care of your oral hygiene thoroughly after treatment, they will naturally heal.

Receive your once-a-year health insurance benefit!

As mentioned above, some people avoid treatment because of symptoms such as tooth sensitivity and bleeding after scaling. However, since the state also provides citizens with a once-a-year health insurance benefit, many people should know that this is an essential treatment for maintaining oral health.

Anyone aged 19 or older can receive the health insurance benefit once a year and undergo the procedure at a lower cost. The price varies slightly depending on the size of the medical institution, but in the case of clinic-level facilities, treatment is usually available for around 10,000 won. In addition, pregnant women whose gums become weaker due to hormonal effects may receive additional discount benefits. The insurance benefit for scaling is renewed every year on January 1 and can be applied until December 31, so it is a good idea to visit the dentist at least once a year to check your teeth and receive scaling as well to take care of your gum health.

Scaling is the foundation of preventive treatment and one of the treatments that must be performed for oral health. Rather than postponing treatment because of symptoms such as tooth sensitivity and bleeding after scaling, if you have not yet had scaling this year, or if it has been a long time since your last scaling, why not get scaling at a nearby dental clinic in the near future? Thank you.
