Warning Signs to Watch For
Excessive treatment recommendations: If a clinic says that multiple cavities must all be treated immediately at your first visit, or that even healthy teeth need treatment, get a second opinion from another dentist.
Avoiding cost explanations: It is best to avoid clinics that do not clearly tell you the treatment cost or that say “we’ll know once we try,” without mentioning the possibility of additional costs.
Rushing treatment: Be cautious if they pressure you into immediate treatment with comments like, “If you don’t do it today, it will get worse,” without adequate consultation. Unless it is an emergency, it is normal to be given enough time to think.
Lack of equipment or facilities: Clinics that diagnose only by visual inspection or plan treatment without even taking X-rays may have difficulty making accurate diagnoses.
Frequently Asked Questions
How much does cavity treatment cost?
It depends on the size and location of the cavity. A small resin filling may cost about 50,000-100,000 KRW, root canal treatment about 150,000-250,000 KRW, and if a crown is needed, around 300,000-800,000 KRW. You can only know the exact cost after an examination, so it’s best to consult several clinics and compare.
When can I eat normally after cavity treatment?
After resin treatment, you can eat on the same day, but if you had root canal treatment, avoid hard or irritating foods for 2-3 days. Extra caution is needed while a temporary filling is in place.
Does cavity treatment hurt?
Modern cavity treatment is performed under local anesthesia, so it is almost painless. The injection itself can also be made much less painful by using surface anesthesia first. You may feel some discomfort after the anesthesia wears off, but severe pain is uncommon.
Why does root canal treatment require multiple visits?
Root canal treatment is the process of completely removing and disinfecting infected nerves, and it usually requires 2-4 visits. If it is not disinfected sufficiently, there is a risk of reinfection, so it is safer to proceed in stages.
How long do treated teeth last?
With proper treatment and care, treated teeth can last 10-20 years or more. Regular checkups, proper brushing, and avoiding hard foods are important.
Can I leave a cavity untreated if it doesn’t hurt right now?
Absolutely not. Cavities are a progressive disease and do not heal naturally. In the early stage there may be no symptoms, but if it progresses to the nerve, severe pain develops and treatment costs increase significantly. Early detection and early treatment are best.
Closing: For cavity treatment, accurate diagnosis and appropriate treatment are what matter most. The five clinics introduced above all have the expertise and reliability needed for cavity treatment. Considering your location and lifestyle, choose 2-3 clinics and get direct consultations, then receive treatment at the place you trust most.
