FAQ

Cavity Treatment questions

Still unsure? Message us on WhatsApp at +82 10-2762-3828.

How do I know if I have a cavity?

Common signs are sensitivity, toothache, dark spots or holes, food getting trapped and pain with sweet, hot or cold food. Some cavities have no symptoms and are found at check-ups.

Will I need a filling or a crown?

It depends on how much tooth is affected. Small to moderate cavities often need a filling, while extensive decay may need an inlay, onlay or crown.

Can decay come back under an old filling?

Yes, recurrent decay can develop around existing fillings. Your dentist checks and replaces them when needed.

How can I prevent new cavities?

Regular check-ups, professional cleaning and good daily care help. Read about dental sealants.
