Q. Does fluorine coating help preventing cavities?

A. ‘Yes’

Fluorine is the safest and easiest way to prevent cavities, and with the slightest care, one can easily undergo this preventive measure.
Fluorine is one of halogen, which surrounds the outer tooth to protect the tooth from acid, to help melted minerals recover, and to keep cavity viruses from develop.
Fluorine coating is effective as a prevention and treatment for all ages, but since permanent teeth take place from the age of 6 to 12, and become mature, the rate of cavity occurrence rises, so fluorine coating during these ages is helpful in cavity control. Therefore, fluorine coating is the most needed treatment for elementary students, who are clumsy at brushing teeth, and whose permanent teeth more prone to cavity. It is effective to receive the treatment every 3-6 month.
For the dental care and cavity prevention, regular dental checkup is important.

Q. Is teeth whitening safe?

Yes. Extensive research and clinical studies indicate that teeth whitening under the supervision of a professional is safe. In fact, many dentists consider whitening as one of the safest cosmetic dental procedure. As with any teeth whitening products, Zoom! is not recommended for children under 13 years of age, and for pregnant or lactating women.

Q. What will I experience during the Zoom! In-Office Procedure?

During the procedure, patients can comfortably watch television or listen to music. Individuals with a strong gag reflex or anxiety may have difficulty undergoing the entire procedure.

Q. Are there any side effects of Zoom teeth whitening?

Some patients may experience hypersensitivity during the treatment. The Zoom! Light generates minimal heat which usually causes discomfort. On rare occasions, a patient may experience minor tingling sensation immediately after the procedure, however, it dissipates eventually. You can also ask your dentist to supply you with oral gel to apply after the treatment.

Q. How does the Zoom! In-office whitening system work?

The Zoom! Light activates whitening gel’s active ingredient, hydrogen peroxide. As Hydrogen Peroxide breaks down, oxygen enters the enamel and dentin layers, and bleaches pigmented substances while the structure of a tooth remains unchanged. The Zoom! Light helps activating hydrogen peroxide and penetrating the surface of the tooth. A study has shown that use of the Zoom! Lamp increases the effectiveness of the Zoom! Gel by 26% or more, providing an average improvement of up to eight shades.

Dental Implants

Q. Can I get several immediate implants at the same time?

It is possible if you have strong and healthy alveolar bone mass & density. However, if the teeth are damaged or suffering from periodontal diseases, delayed implant must be performed – 6~8 weeks after the extractions

Q. Does an implant get loose if it is placed where a tooth is extracted?

No, it doesn’t. Immediate implant is only performed when alveolar bone around the extracted tooth is strong and healthy, and the loose area, if there is any, will be grafted with bone from the extracted tooth.

Q. Can I get an immediate implant for a tooth with a cavity?

A tooth with a cavity or periodontal disease may not have enough alveolar bone mass and density.  An accurate assessment must be done before deciding on an immediate implant.

Q. Does dental implant procedure hurt much?

In general, there isn’t much pain except the moment the anesthetic wears off. However, there tends to be more pain if the degree of operation is complex thus requiring longer operation time and more modifications on the surgical site. Although maxilla implant is generally more complicated than mandibular implant, patients do not feel much of discomfort because of the advanced anti-pain system of Hus-hu such as Conscious Sedation Implant program or use of Patient-Controlled-Analgesia (PCA).

Q. Does bone grafting must be done for all dental implants? When can an implant be placed after the bon

Bone grafting is done when there isn’t a enough bone mass available to place an implant. Dental Implants on a poor bone mass will increase the chance of nerve damage or antral perforation as well as the loss of dental implants. Depending on the condition of alveolar bone, implants can be placed immediately, or 2~3 months after the bone grafting.

Q. Can a replanted tooth be used semi-permanently?

It is required to get a regular check up once a month for 6 months, and every 3 months after 6 months. If a replanted tooth isn’t fixated or get a recurrent inflammation and severe pain, you must extract the tooth out and replace it with a regular dental implant.

Tooth replantation usually cost lower than dental implant procedures. Replacing a replanted tooth with a regular dental implant is also possible at lower cost if the replanted tooth does not last longer.

Q. In what cases can a tooth be replanted?

Tooth replantation is mostly used on a tooth when a root canal procedure cannot be performed successfully. It is best when the root is not broken, and the periodontal ligament of a tooth is undamaged and healthy.


Q. Does orthodontic appliance hurt?

A. “No.”

An orthodontic appliance, attached to the tooth, gradually moves the tooth to a desired space. Therefore, attaching an orthodontic appliance does not hurt, although some patients expressed a slight pain on the tooth as the tooth starts to move. However, this pain is not unbearable, and will diminish as the correction proceeds.
The degree of pain depends on each person. Some will say it merely feels stiff, while others say it hurts. The pain can be alleviated with the help of a painkiller, such as Tylenol, or cold drinks.

Q. When do you need orthodontic treatment?

1. Crowding(Teeth Erupting Too Close) 2. Spacing (Too Much Space Between Teeth) 3. Underbite(Lower Front Teeth More Protrudent Than Upper Ones)
Upper Front Teeth Protrusion
Dental Midlines Not Matching.etc
4. Overbite (Upper Front Teeth Fully Covers Lower Teeth) 5. Openbite (Some of Upper and Lower Teeth Not Matching

Q. What is the procedure for dental examination for braces?

Our dental examination includes general photos, impression(to have dental mold), X-rays and 3D CT scan to check your bite and degree of your nose, mouth, and jaws and orthodontist check-up, etc. It takes about 30 minutes and it takes about 3~5 days to know the result.

General Dentistry

Q. Does scaling whiten teeth?

A. Scaling removes impurities from teeth and make them clean, so you may get a sense of their teeth becoming clearer, but it does not “whiten” teeth in terms of the coloring.

*Difference between Whitening and Scaling

– Scaling (Teeth Cleaning): procedure to remove tartar on the upper epithelium of the surface of a tooth.

– Teeth Whitening: procedure to whiten pigmented/discolored tooth
Scaling removes tartar, plagues, nicotine, and pigments, shines the surface of a tooth, and prevents gum diseases such as bad breath and periodontal diseases.

Q. Wisdom Tooth covered by Gum

Q. Teeth near molar have been hurt since few days ago. I went to dentist and there was a wisdom tooth. It seemed fine but was covered by gum and it was swollen and painful due to infection. Neck, cheek, gum, and throat on the side of wisdom tooth are swollen, and all teeth are in pain. I feel like I should treat the infection. Is it possible to remove the gum around the wisdom tooth without pulling it off? In my case, the infection appeared because substances would be washed off due to covering gum, not because of horizontally lying tooth. Then is it possible to remove the covering gum, leaving the tooth alone?

A. Wisdom tooth is the third molar which appears at the age of 18 to 20 or in some cases it appears even later or does not appear at all. It is recommended to take off the tooth since it occurs big pain or disease in that it tends to be covered or to grow horizontally due to lack of space between jaw and teeth where wisdom teeth comes out. It seems like wisdom tooth pericoronitis in your case. It can be treated by pulling off the tooth or by cutting off the gum around. To cut the gum, wisdom tooth should not be tilted, not affect other teeth nearby, and take a good care of it afterwards such as brushing teeth. Also gum around the wisdom tooth should be sticked firmly to bone so as not to have any problem later. With all these conditions satisfied, it can be treated by cutting off the gum and not pulling off the tooth. Even if cutting off the gum is possible, it is prior to treat the infection firstly since it is still ongoing. I recommend you to go to dentist, get a exact diagnosis, ask the possibility of cutting off,, and get the proper treatment.

Q. How do I treat aching gum?

The cavity filled with amalgam long time ago has been aching so I visited a dentist’s office. The unfilled space had cavity again, so I had it treated and filled it with gold amalgam. Even though all treatment has passed, the aching persists. The dentist told me to wait and see if the aching gets sever, in which case he will execute endodontic treatment. I don’t quite understand why endodontic treatment has to wait.

Endodontic treatment removes nerve tissue of a tooth, so to go through such treatment means to lose a tooth’s life. If the cavity is severe, nerve tissue’s degree of exposure can be determined during the elimination process. If the cavity is placed in the borderlines of nerve tissue, dentists usually watch the progress after temporary or permanent charge. If the tooth can function after the charge, then the tooth can be permanently be in use without having to go through endodontic treatment. A healthy tooth does not have to go through endodontic treatment and reduce its life. A deep cavity can cause aching even if the nerve is not damaged. The dental pulp, a nerve system for teeth, is a soft tissue with ample nerve and blood vessel, and thus very sensitive. The teeth may ache not only due to damage to nerve system, but also due to sensitive response to charging materials, which are different from the ingredients of teeth. First and foremost, one must bear until the tooth can become accustomed to a changed environment due to the charged materials. During this period, try to avoid stiff and tough food, and avoid chewing hot or cold food on the charged side of the mouth. Once the tooth has undergone this period, the nerve tissue will return to the original state. If the nerve tissue is actually damaged, the pain will be so severe that one cannot even fall asleep. In such cases, endodontic treatment is necessary, so it is wise to stay vigilant, as your dentist suggested.

Q. My gums bleed while brushing teeth. Is it because the way I brush my teeth?

If your gum bleeds while brushing your teeth, it is likely that your gum is infected. Therefore, it is advised that you visit the dentist’s office, get a checkup, and have it treated. Sometimes, inappropriate brushing may wear away your teeth, and may also degenerate your gums. We recommend using a soft-bristled toothbrush and learning appropriate way of brushing your teeth.

Q. I have such a bad breath. How can I treat it?

The cause of bad breath can come from either within the mouth or outside of mouth. The causes originating within the mouth are plaque, food residue, or the coat on the tongue. Cavities or periodontitis may also cause bad breath.
The causes originating outside of mouth are digestive system disorder (acid reflux, etc.), diabetes, or smoking. We recommend you to come in and check your oral status, followed by either scaling or cavity treatment. When brushing your teeth, brushing your tongue also helps with bad breath. In most cases, uncleansed tongue may lead to the coat on the tongue, which then causes bad breath. If bad breath persists, we recommend you to seek other medical checkup.

Q. Why are teeth sensitive after dental cleaning?

After the dental plague from teeth is removed, the swollen gums can be retracted and this will lead temporary exposure of teeth root. However this is transient, so it won’t last long.

dental cleaning, dental scaling, swollen gums, sensitive teeth, dental plague

Dental cleaning is the removal of ONLY dental plague from teeth with the intention of preventing cavities (dental caries), gingivitis, and periodontal disease. So it will not affect your tooth!
