Small cavities generally do not hurt. But the best time to fix a cavity is while it is still small so that a conservative filling is all that is required. Some people ignore problems that are not yet symptomatic…but small cavities can get bigger in due time and require more extensive treatment later on. When caught early, small cavities are generally easily fixed. Please consider using fluoride products and improving oral hygiene to reduce the risk of cavities. At IQ Dental Group, we only use high-quality composite fillings or fluoride releasing fillings.
