I went for my regular dental check-up the day before yesterday...

The moment I visited the dentist and opened my mouth with an "Ah" in front of the doctor, as usual.

The doctor suddenly changed his expression and said, "Oh~ you need treatment," so I thought, "Huh... what's going on?"

A cavity had formed again in the spot where I previously had a filling due to tooth decay... Sigh, I had no choice but to go for dental treatment.

Next time, if a cavity occurs again in the same spot, I heard that there is a limit to filling treatment...

Phew... I save up money for various things, but if the crown gets fitted incorrectly, it could all be gone in an instant... It made me realize I need to take good care of it...
